Title: Igaro D1 USB Dynamo Power Converter
Post by: igarocom on November 30, 2016, 05:49:55 pm
Hi,

Andrew here from igaro.com. I hope I don't fall foul of the commercial rules - (mods read this out before hitting delete).

Every so often we aim to raise brand awareness by offering Igaro D1's with a massive discount in return for reviews posted on a cycling forum thread, the last being on lfgss.com. It's mutually beneficial - short-term we try to put ourselves out of business  ::-), riders ride for less  :thumbsup, and others have more honest feedback for comparison and decision undertaking.

This week it's yacf's turn.

1. an Igaro D1 to you with a 50% discount - so probably the worlds finest USB charger momentarily becomes the cheapest!
2. you agree to post a review in this thread (say what you want).
3. you have to be a yacf user prior to the date of this post.
4. you must own a dynamo hub or be willing to buy one.
5. reviews must be posted within 3 weeks (unless you're going on a longer tour etc).
6. the unique code you'll be given expires 9/Dec.

Then we'll link back to this thread from the website.

If you're up for it stick a post in this thread to say so and send me a PM for a unique code which will give you the discount. Starting now 30/Nov and ending 7/Dec.

(review units come with our usual lifetime warranty).

Currently a Luxos user (running off a Shimano DH-3N80) which is fine for low demand stuff like keeping the Garmin going but unconvincing for charging phone (or cache battery) over longer distances.

Post by: marcusjb on November 30, 2016, 10:31:03 pm
These little feckers are good.

After another miserable wet long ride with a Luxos giving intermittent action (it actually never failed as a light this time, but this is the gen 1 version and I had to have the USB lead unplugged for much of the second half of my trip to the south of France - so no charging and no bright beam).

Anyway, Luxos are basically brilliant lights, but sucky in the rain and this is largely down to the USB thing.

So, I have ridden a few things with the Igaro (I have yet to replace my Luxii with something that is just a light, but that is primarily down to laziness and the pound being so weak that what would have bought me a nice light in June now just about gives me enough for a box of matches). Some audaxy stuff with a SONdelux and some touring stuff with a SON28.

What is there to say? It works. Brilliantly.

Not much more to it really.

The only detractor is the USB lead being permanently fitted (this is good for waterproofiness and reliability) - it is a bit of a pain in the arse if you use a bike in different ways. It is a bit of a pain if I go out on one of the audax bikes for a quick 50km thrash or whatever and it is fitted. If I do not have a bag fitted anywhere, the lead is flapping about a lot.

Anyway - minor stuff.

It works, it is way tinier than you expect, it is well made, I have yet to experience it getting hot at all when descending at speed (even in 1000+m mountainous areas).

Having two devices rather than the all in one Luxos may seem less good on paper, but a Luxos can not be relied on for USB charging in wet weather, and has let me down on the whole lighting thing in wet weather as well. (I have both gen 1 and 2 Luxii and both have had moments in poor weather).

Oh and the little sticky 'feet' on the igaro don't really like being moved from bike to bike, but I can live with that - I suspect application of some gorilla glue will sort them out.

I'd like to give this a try out too, I have a Luxus at the moment, but the n+1 (fixed edition) will be dyno'ed as well, but I'm debating the lighting options in my mind at present, this would be a great thing to free the options away from a light and built in charging solution... plus i could test it on my present SON equipped geared bike, so win!

hi Andrew, are you planning to make one with the cables coming out of the same end? this would make it much neater if the charger is mounted under the top tube, down tube or stem. also, any plans on an option in "universal black"? thank you!
Title: Re: Igaro D1 USB Dynamo Power Converter
Post by: igarocom on December 01, 2016, 10:51:24 am
Check out the Facebook page for internal bracket pictures (it's only in a prototype stage at present but you can make one yourself).

No plans to paint - it's titanium so doesn't require it.  :thumbsup

Wires all out of one end is impossible due to space constraints within the D1 body.

The question of how this compares to a USB-Werk is more interesting to me than how it compares to a Luxos-U. So some of you reviewers: please address that.
Title: Re: Igaro D1 USB Dynamo Power Converter
Post by: igarocom on December 01, 2016, 11:51:54 am
The USB-Werk is a little different, it works around the low frequency dynamo AC by charging it's li-ion first (no power out) then discharging it to the device (no power in).

1. you get stable power out for a period of time regardless of whether you stop [good]
2. you get no power out for a period of time [bad]
3. there is a period where no power is consumed from the dynamo [bad]
4. li-ion and associated step up/step down circuitry introduce a 25% efficiency drop [bad]
5. li-ion's degrade after 500 cycles [bad]

The D1 omits 2,3,4,5 and does it's best to provide 1 for a longer period by way of high efficiency and frequency detection at low speed.

Do you have a minimum bend radius for the cables, or is it just a matter of avoiding kinking?

No minimum bend, let's say 180 degree within 20mm^2. As with all small core cable shouldn't be continuously flexed (unsure what have you in mind).

Really just picking up on zigzag's point and wondering how sharp a bend was possible to get the cables pointing the same way, if that's what the installation called for. 

Sounds like 'be sensible' is the answer ...

Don't forget everyone, as part of the deal you must be able to post a review within three weeks of receiving it. If you don't own a dynamo or have no time before your audax/tour come summer - please reconsider - it's not just a discount as they're being offered below cost here.

I'm interested - I have a Shimano dynohub on my solo touring bike and would be interested in having a charging facility (principally for phone) when cycle camping etc. When do you think we would receive them?
Am I right in thinking that for the purpose of the initial review I could just connect it and pop it in my bar bag along with the phone? I'm happy to have the temporary restriction of needing the bar bag pending a better set up later.

Delivery 1-2 working day(s) (UK). Dispatch 0-1 working day(s). Stock is plentiful.

Re: temporary bag

Short answer yes, but read "Will the D1 heat up if I place it in a bag?" in the FAQ to ensure you understand the condition in which this is no and ensure it doesn't occur until the unit is mounted as per the instructions.

Typo/style suggestion in one of those FAQs ...

Quote
How theftproof is the D1 / should I remove or risk it?

The D1 is very small and discrete and it's mounted in an unsuspecting place (not the top tube or side of bike) where it's unlikely to be noticed. Most dynamo hub power converters are mistaking as a powerbank but the D1 is obviously too small to be one. These two points reduce the exposure of the D1 being stolen however it is up to you to weigh up the risk.

discreet
unobtrusive

I have 2 dynohub setups, a 2nd gen Luxos U / SON Delux on my Audax bike and a Luxos B / Shimano DN-3H80 on my commuter.   Planning on trying this on both setups,  would be handy to have a charger on the commuter,  but would also be good to compare with my increasingly temperamental Luxos U. 
This sounds like a good deal.   Exactly how much will we pay?

Looking at your site I can't see a comment or voucher code ? So how does discount work ?
Title: Re: Igaro D1 USB Dynamo Power Converter
Post by: igarocom on December 02, 2016, 01:42:27 pm
jsabine -> thanks for the heads up on that particular FAQ entry.

OK lets begin early to save on the logistics, if your name is down here as wanting a unit send me a PM, I'll generate a unique discount code which will give you 50% off the unit price. You may only order 1 unit and you may only order once  ;). On the bottom of the web page stick the code in "Offer Code" and the price will update. It may take up to 24hrs before the code activates but hopefully it'll be much sooner.

Please make sure you've read https://www.igaro.com/d1 so that you're comfortable with the specification - and no, you can't power a hairdryer with it.  :thumbsup:

Many of you are asking if you can power a USB and lights at the same time, this depends on a) dynamo wattage (greater as speed increases) b) light wattage (newer LED lights take almost all the power) and c) USB device (Garmin etc don't take much power, a large powerbank will). The D1 consumes no power if no USB device is plugged in. More on this and other FAQ's here: https://www.igaro.com/d1/faq

£44.47 inc VAT & postage (UK) - Shimano, SP

SON is about £1 more - you get piggyback connectors crimped, soldered and heat shrink wrapped.

International postage is £1-2 more.

Andrew, I have a Sunup EcoDyn dynamo which produces DC - would you device work with this?

Quote
The Sunup Eco spoke dynamo is based on a three phase generator unlike standard hub dynamos which are single phase. The advantages of three phase generators are that they:

 
  •     are inherently more efficient than one phase generators;
  •     produce more stable electricity (lights will not flicker at low speeds); and
  •     produce direct current (DC) as opposed to the alternating current (AC).

Hi Russell,

It's not so suitable - you'd be better off buying a buck switch and including overvoltage protection. Here's why;

1. only half the rectification circuit would be utilised which would overheat if you consumed more than 1A - that could destroy the D1.
2. the rectification circuit would be obsoleted by the DC and has a efficiency penalty.
3. the D1's digital frequency monitoring would most likely not work (depends on the frequency from the dynamo) therefore it would not turn the USB off if you were to go very slow. That could result in devices toggling on/off quickly.

Regards, Andrew

What's your take on a 'first impressions' review within the three weeks, with the promise of a fuller one later?

No problem at all installing it and using it sharpish, but realistically, a proper view on it takes either a tour or a decently long ride - and from an audax perspective, I'm not likely to get anything more than a 200 in before Christmas. (I'm quite happy to be told I'm overthinking this.)

Post by: igarocom on December 05, 2016, 09:02:51 am
That's pretty much it, I can't ask for a long-term test with just a three week window. Some angles that could be covered and which normally cause issues with dynamo chargers;

1. compatibility with your devices
2. slow speed performance
3. build quality, your impressions on reliability, water resistance
4. installation, appearance, neatness
5. effectiveness at cruising speed (how fast a device charges within a given amount of time)

What options would you recommend for wiring the D1 in conjunction with a light?
I realise that the unit should be wiring in parallel with the light, but was wanting to know what solutions people had found to do this neatly.

I use an Exposure Revo light which I move between two bikes (each bike is equipped with it's own dynamo wheel and cable for the light).
It would be good to have the option to easily move the D1 between bikes. I assume soldering and heat shrinking a branch off the main light cable would be the way to go. I was thinking about the option of getting some kind of discreet secure inline cable connector to attach the D1. The ones that B&M use on the E-WERK look good, but haven't been able to find these or similar as a loose component. Does anybody know of anything suitable?

That's pretty much it, I can't ask for a long-term test with just a three week window.

Disappointingly, I've had to send my SON back for a service so I'm highly unlikely to be able to get a review done in time. I was already thinking of getting one of these before the offer, so will probably put an order in ahead of LEL anyway. Looking forward to seeing the reviews...

What options would you recommend for wiring the D1 in conjunction with a light?
I realise that the unit should be wiring in parallel with the light, but was wanting to know what solutions people had found to do this neatly.

I use an Exposure Revo light which I move between two bikes (each bike is equipped with it's own dynamo wheel and cable for the light).
It would be good to have the option to easily move the D1 between bikes. I assume soldering and heat shrinking a branch off the main light cable would be the way to go. I was thinking about the option of getting some kind of discreet secure inline cable connector to attach the D1. The ones that B&M use on the E-WERK look good, but haven't been able to find these or similar as a loose component. Does anybody know of anything suitable?
At Kim (OTP) 's recommendation I've used Tamiya connectors before in similar application. 
In that case it was power convertor into one half of the connector, dynamo & light into the other.

If you wanted to move the D1 along with the light between bikes you could put those two together into one side and the dynamo into the other?

Very kind of you, although tbh I don't know when I'm going to have time to test it anyway so I'll pass for now. So busy at work at the moment, and then going away in two weeks the Christmas period - I was quite keen to get my dynamo set-up sorted in time for the Poor Student but that might end up being the test ride...

Shoudn't need extra charging capability for a 200 anyway.

Is the bracket (as pictured on Facebook) to hold the unit inside the head tube essential, for heat dissipation for example?

As I have mudguards, can I not just fit it into the head tube and use the mudguard to hold it in place, or will that not work?

Unsure how you will hold it using the mudguard, but the body should press against metal for the internal mount - for heat dissipation when going downhill with no load attached. That's why the mount was made from aluminium not titanium.

At some point we'll begin fitting them to the external capacitor lead as we have plans to introduce a 20,000uF capacitor bank for extreme low revolution performance with high current devices (specifically the Sony Xperia Z3 which is a nightmare at low RPM) and for combining a 12v solar panel.

Why does it have to dissipate so much heat anyway?  Are you using a zener shunt for over-voltage protection, rather than crowbarring the dynamo?

As a mudguard blocks the hole in the underside  of the fork crown, any put into the steerer tube isn't going to fall out. However, if it is going to overheat in this position then it's a no go.

Could the alloy bar go through this 'plug' instead, then make a lip and fix it to the bottom of the mud guard?

The D1 has a small heat capacity hence some form of transfer ability is needed should the protection circuit cut in.

It doesn't for everyday riding but an 'edge condition' such as a 60kph downhill section for several minutes without a load will trigger the protection. The D1 is small and doesn't have much volumetric heat capacity. Speed and subsequent air flow will take what is generated away but hidden up the fork would undo that.

Igaro D1 Review

The Igaro D1 was bought to replace a Lightcharge USB charger I've been using on Audax events of 300km and over for the last 4 years. Recently the Lightcharge has become unreliable - the switch has become difficult to operate and the wiring needs attention on a regular basis. I use an old Son 28 hub to power a B & M Cyo and Secula rear light. USB charging is limited to recharging a Sigma Rox 10 GPS and occasionally an Anker 5000mAh cache battery.

Ordering and Delivery

The Igaro D1 was ordered on a Friday afternoon and the package arrived Royal Mail “Signed For" on Tuesday morning.

(http://i1380.photobucket.com/albums/ah171/kieronyates/Mobile%20Uploads/EF25989B-721A-44D5-AD16-7FF2D45D2858_zpsq1femktd.jpg~original) (http://s1380.photobucket.com/user/kieronyates/media/Mobile%20Uploads/EF25989B-721A-44D5-AD16-7FF2D45D2858_zpsq1femktd.jpg.html)
Package with business card for size comparison.

Box unpacked

Inside the box you have the Igaro D1 unit; a couple of spare spade connectors (unused); two mounts (unused at the moment - the double sided tape was a bit feeble, and I thought they were unnecessary); two zip ties (unused - used my own more robust zip ties); FAQ sheet (unread as I'd already read the FAQs online); installation instructions .

Installation

This really was very simple. I detached the B & M Cyo spade connectors from the Son 28 hub and attached to the piggyback connectors of the Igaro D1. The piggyback spade connectors were then connected to Son 28 hub: this, for me, was a minor issue as fitting was tight and difficult to secure, eventually needing pliers to force down the connectors onto the hub's spades - I can imagine this being a bit frustrating if an inner tube change is required on a cold, wet night.

(http://i1380.photobucket.com/albums/ah171/kieronyates/Mobile%20Uploads/7f0ba8c1-ef08-462e-9d44-fc7aa3011098_zpsyhftotir.jpg~original) (http://s1380.photobucket.com/user/kieronyates/media/Mobile%20Uploads/7f0ba8c1-ef08-462e-9d44-fc7aa3011098_zpsyhftotir.jpg.html)

The cable of the Igaro D1 was then threaded and secured around the fork and the main Igaro unit zip tied to the side of the head tube. The USB socket was fixed to the underside of the handlebars.

(http://i1380.photobucket.com/albums/ah171/kieronyates/Mobile%20Uploads/09ea3aea-8ee0-4904-b411-a1578b1372a2_zpschor6ynf.jpg~original) (http://s1380.photobucket.com/user/kieronyates/media/Mobile%20Uploads/09ea3aea-8ee0-4904-b411-a1578b1372a2_zpschor6ynf.jpg.html)

(http://i1380.photobucket.com/albums/ah171/kieronyates/Mobile%20Uploads/dac34800-ce34-4641-84ee-690b6294fd18_zps0ruxk7r5.jpg~original) (http://s1380.photobucket.com/user/kieronyates/media/Mobile%20Uploads/dac34800-ce34-4641-84ee-690b6294fd18_zps0ruxk7r5.jpg.html)

Testing

To test the unit I set off on my usual commute from Blackheath to Hackney Downs with my GPS switched on and 50% charged. Out on the road, once I began rolling, charging started pretty much instantaneously with no appreciable drag.

The walk through the Greenwich foot tunnel showed me charging didn't take place at normal walking pace and I later determined that it only kicked in at around 10km/h - not a problem as far as I'm concerned. Forty minutes and 13km later, at Hackney Downs, my unit was showing it was 80% charged.

Seven kilometres into the return journey the GPS was nearly fully charged. As it was getting dark I tested the unit in conjunction with front and rear dynamo lights; this increased drag but lights worked perfectly and the GPS unit showed it was still drawing power from the dynamo. I reached home with the GPS showing it had retained its 100% charge.

Conclusions

The Igaro D1 is a very compact and simple device that does exactly what it's supposed to. The unit is well constructed and finished and coming with a lifetime user guarantee promises many years of trouble free charging.

My reservations are the fact that the USB socket is potentially vulnerable to water penetration (I'll probably try to remedy this with a bit off Gorilla Tape stuck over the end when not in use) and the fiddliness of fitting the piggyback spade connectors which could be problematic if a tube change is needed on the road at night - as someone who routinely uses back-up battery lighting and a cache battery I don't see this as a deal breaker. I will also be paying attention to how hot the unit gets and will make adjustments to its mounting if necessary.

I'll update this review as and when I have anything additional to add.

I'm planning on wiring my Igaro piggybacked off the lamp input spades to prevent any fiddlyness with wheel removal,  in my case it will also mean only one set of wires to be run up the fork leg, though I realise in your case with the low mounted lamp,  you won't have that issue. 

All sounds good though, 

I'll hopefully get time to fit mine this weekend.

Igaro D1 Review

The Igaro D1 was bought to replace ...


Excellent feedback. Re your points:-

1. USB wasn't designed for outdoor usage, the pins are close together and will quickly suffer electrolysis. For this reason the USB plug is designed to drain water (hence the tiny gap around it) and is replaceable at little cost to customers. We can also supply replacement ports for DIY (very easy to replace) or for longer tours. If we were to include a cover it would only be waterproof when the unit wasn't being used. If we were to fix the port into the device (which would make the D1 body bigger) then the unit would have to be thrown when the USB port eventually fails. This is a big problem with our competitors but one users don't immediately pick up on.

2. The D1 monitors the stability of the supply. The dynamo frequency < 10kph for your wheel size/device was determined to be too low and hence it shut off. This is to prevent potential software lockup (smartphones, powerbanks) and worst case damage to the USB device, some of which do not enjoy rapid power cycles.

3. The 3M stickers are as good as it gets but the small surface area doesn't help. As you say, discard if not required.

Thanks for your feedback and I'm glad it's working well for you. Even better that it continues to work with lights as that's a popular question. Perhaps you can post the model of the lights and GPS unit?

Regards, Andrew

Edit: I see you've specified the GPS unit as I was typing. How about the front and rear lights?

Hi Andrew,

Thanks again for the great offer you have provided yacf users.

All of the information about the kit I use is in the first paragraph. I think the Cyo headlight I use is the 60 Lux version bought in 2010 and the SON hub is also a 2009/2010 model.

Ah those stickers!
Couldn't get the backing paper off until I'd completely ruined the adhesive with my sticky fingers on the other side ! :facepalm:

The zip ties are too short.  My head tube (for a 1-1/8" threadless) has a circumference of ~120mm, so 140mm zip tie will not be enough to attach anything to it.  Modern tapered head tubes are likely to be bigger still.

Those are not deal breakers though!

I've just been for a short test ride comparing the charging current to my Moto G3 phone running the Ampere app which measures the instantaneous net charging current.

Unfortunately although I carefully turned off wi-fi, mobile data, GPS, bluetooth, put it in Flight mode, what I forgot was the screen adaptive brightness, so the figures probably fluctated as I went in and out of shade.  However.... the Luxos U seemed to be giving the phone about 670mA (mostly +/- 20mA) whereas the Igaro D1 fluctuated between around 100mA and 340mA.  The correlation with speed was quite weak - some of the highest readings were when I was going quite slowly !

Obviously the cache battery of the Luxos would be expected to keep things steadier, and it's tough (well nigh impossible) to keep it charged when the lights are on, whereas switching the lights on in parallel with the Igaro, didn't make any noticeable difference to the readings.  As this was in daylight there was no way of checking if it dimmed the lights.

More testing to be done, but so far I'm a little underwhelmed.

With my eWerk, rather than trying to plug the light connectors onto the piggyback spades at the hub, I unplug the light connectors from the hub, plug them into the charger piggyback spades away from the hub, then plug the combined connectors into the hub.

Try it.

Bear in mind the numbers I quoted from the app are (supposedly) the net values going to the battery. The discharge rate when not connected, just running the OS and the screen (quite bright as it was outdoors), was around 250mA so that would have to be added to give a more realistic figure coming out of the Igaro.

I was going to say stuff buying a multimeter, I'm not fussed about the actual current values, only in comparing how fast the phone gets charged, but then I saw the price on the one you linked  :o so duly ordered, and will report back (in addition to trying the ideas you pm'd)

Sorry I misread the net. Assuming the App is accurate to some degree then that makes

Gross: 350 - 590mA

3W/5V = 600mA

Plus conversion efficiency penalty (0.84-0.9) places output into the 500mA region which matches your range.  :thumbsup:

The luxos can do more temporarily while it's cache discharges.

ISTR that these dynamos are only a nominal 3W at something like 15kph.  I may be mis-remembering it, but aren't they actually 1A constant current and variable voltage depending on speed ?  Kim will be along in a while to correct me if I've got that wrong. ;D

Averaging 22kph, and charging only the phone, the cache on the Luxos never seems to discharge to the threshold level at which it cuts the USB power - which, if the numbers from the app are correct suggests it's actually getting nearer to 5W ?    Whereas the Igaro is somehow 'throttled' so that it can only take a maximum of the nominal 3 W however much the dynamo is capable of at a given speed?

OK I didn't see your speed anywhere, assumed it was around 15kph.

So this could be the smartphone setting the current level based on when it initially received power (to the 500mA USB2 spec). There's no way around it other than adding a passthrough power bank or plugging in at 22kph. Unfortunately USB specification does not cater for re-detection of power supply current limits. I wrote about this phenomenon on the thorn cycles forum.

"most USB devices that accept high current input will park the current at a determined level. They do this by increasing load and testing the voltage drop on power on to determine what power level can be drawn (i.e USBv1 is 100mA, USBv2 usually 500mA-1A, power adapter 1.5-2A). If I take the Sony M4 Aqua for example (using an Igaro D1) the input current is 0.74A. It doesn't matter if I go 60mph, it will remain 0.74A. If I plug the same phone into a wall charger it'll take 1.5A. Why? because it "asked" for 1.5A and the voltage drop was too low, so it switched to 0.74A and stuck at that level. Most phones and USB powerbanks will do this - it's a requirement of being able to charge from USB sources of different current levels."

Typo/style suggestion in one of those FAQs ...

How theftproof is the D1 / should I remove or risk it?

The D1 is very small and discrete and it's mounted in an unsuspecting place (not the top tube or side of bike) where it's unlikely to be noticed. Most dynamo hub power converters are mistaking as a powerbank but the D1 is obviously too small to be one. These two points reduce the exposure of the D1 being stolen however it is up to you to weigh up the risk.

discreet
unobtrusive
can be mistaken for
likelihood

Also: descent is spelled with an 's', and "currently used only by use for quality assurance" => currently only used for quality assurance.

OK I didn't see your speed anywhere, assumed it was around 15kph.
There are lot of folks around here who can maintain an average on the road around 20kph for very long periods of time. 
It's pretty much a necessity for audax rides where the maximum time allowed (including stops for food/sleep) is often based on 15kph.

  this could be the smartphone setting the current level based on when it initially received power (to the 500mA USB2 spec). There's no way around it other than adding a passthrough power bank or plugging in at 22kph. Unfortunately USB specification does not cater for re-detection of power supply current limits.
Am I understanding this right then, that if I put a switch between phone and Igaro, and only connected the circuit when I was moving at a fair speed then it would negotiate a significantly greater current?

USB power 'negotiation' is tricky. It may do this but I wouldn't investigate it until you have more accurate current readings.

Smartphones and powerbanks may choose current based on;

1. USB data (where the chip indicates how much power it can deliver via software)
2. shorting out the data pins, or using varying levels of resistance (mostly older Apple devices, some Sony)
3. fast voltage drop detection
4. battery voltage and temperature

A switch would only help with (3) while a small powerbank with passthrough such as the Limefuel l60x would be a better bet.

If you take 5W for USB at higher speed you leave nothing for lights. When you turn them on some lights will dim (if they are resistive, cheaper B&M lights etc) others may turn off, or the D1 could reset first (more likely). USB specification doesn't cater for volatile power availability so what will will happen is up to the device.

Worth trying, make some steam and then connect the D1 USB to your micro USB (you can leave them loosely fitted and push together while riding).

I have assumed something, the power to your phone (the light and android charging icon, not the App) are stable once the D1 enables power? They shouldn't be cycling on/off.

That's good, the D1 frequency monitoring is working correctly. When your USB reader arrives and it's established as being an issue I'll investigate it with you.

Here's my review

I ordered the unit on Wednesday 7th December and it arrived 2 days later. My present setup is a SP dynamo powering front and rear B&M dynamo powered lights.

1. Fitting

Keeping it simple, I intended to attach it in parallel to the cable powering the lights. I disconnected the lego block and opened it up. I took the cable ends of the light and the Igaro and twisted them together intending to insert them into the lego block but the holes were too small to take a pair of cables. So I took a 5 cm piece of household 2-core cable and a small connector block so the lego block was connected to one end and and the 2 pairs of wires connected to the block at the other.

The Igaro cable was then run up the fork leg alongside the light cable, attached at the fork crown with the light cable. The Igaro unit was attached to the head tube with cable ties and the USB socket to the stem with another tie.

All in, about 30 minutes work.

2. Using

I took the bike for a ride to try out the charging capabilities. I tried 3 devices:

a. Mobile phone (iPhone) I plugged in the phone before setting off and I noticed that it started charging the phone almost immediately at the speed of 7-8 miles and hour. I don't mount my phone on the handlebars and don't use it when riding, it normally just stays in my pocket or in the handlebar bag so I didn't charge it for long, just enough to see if it worked. It did.

b. Garmin 810 GPS Next, I plugged it into the Garmin. This is probably the use I would find the Igaro most useful for. Previously, I have used an external power supply connected to the Garmin when I expected to use it on a long ride, or a night ride as I like to have the backlight on all the time during the dark. The 810 continues to work normally whilst connected to power. The Garmin was not fully charged when I connected to the USB socket and I was pleased to that every few minutes, the % charged would rise by 1% and otherwise worked normally.

c. External battery Finally, I used the Igaro to charge the external battery that I used to power the Garmin previously. This is a small, lipstick sized, battery designed for mobile phone charging. Once connected to the USB port, the charging light on the battery started flashing which means it was charging though I have no way of telling how effective it was.

Conclusion

Overall, a nice piece of kit. Very small and light and clearly does the job. The intensity of the B&M lights did not seem to diminish whilst charging over the USB. This is just my judgement and not the results of any measurements. The criticisms I have are minor. They are:

1. Some indication that the unit is powered would be helpful, like a LED on the unit body

2. A cover for the USB socket when not in use would be useful. I shall make one out of a piece of inner tube or something.

3. Piggybacking the Igaro cable onto the light cable is a bit messy. I think I'll make some sort of matchbox-sized junction box to mount on or near the head tube to take a single input cable from the dynamo and split it to the USB and lights.

4. I'm still unsure about the heat issue. Whilst on my test ride, the Igaro remained stone cold (it was 7 degrees today) but I would prefer to put the unit into some sort of container, maybe combined with the junction box to keep it out of harms way. But that's for another day.

Overall, a nice piece of kit and thanks to Igaro for providing a unit at a discount.

I had something like that in mind as well. It also occurred to me that you could put a switch in the junction, to toggle the power supply between light and D1.

Tried this yesterday.  Even connecting on a long downhill (35kph) made no appreciable difference to the charging current reported by the app.

No need, IME the D1 doesn't take enough power to affect the lights.  You can run them together.

On Ampere: http://forum.xda-developers.com/android/apps-games/app-ampere-charging-meter-t3012890

"The displayed current is an average value from 50 measurements minus the 10 upper values and the 10 lower values. The displayed current can be shaky or unstable or even just zero which means, that the Android system provides such unstable values. Some phones, like the Nexus 4 reports such unstable wide spreading readings when charged with a low current charger (e.g. 500mA), that even the average value is just a joke."

Smaller USB devices take less current so Garmin GPS and lights may work well together. Too many variables to give a boolean answer.

1. it would complicate the design, necessitate sealing around the LED to ensure waterproofing, and you wouldn't be able to see it anyway?

2. not recommended, see previous post or FAQ on why this may make it worse.

3. wiring is outside the scope of the Igaro design (agreed, shame Shimano/SP don't use SON 4.8mm fixings). Take a look at double bullet connectors for coupling under the fork crown.

4. it's not an issue unless you insulate the D1 (inside a junction box) and go really fast for an extended period of time without a USB load attached and with lights off - in which case the D1 could fail. This hasn't occurred and won't occur if the installation instructions are followed. Buyer beware!

You may wish to check our Facebook thread for the internal mounting bracket prototype - it's made from aluminium to counter the lack of air flow.

Review Part 1

My Current Set up:
SP PD8 Dynamo Hub, B&M IQ-X front and B&M Secula Rear

I received my Igaro on Saturday and as I had committed to being about the house I decided mounting it would take precedence over my long list of chores.

As others have said the unit is small and light, I like the overall look of the unit and it could potentially fit in a lot of places on the bike. My use for the charger is really only to keep a battery bank charged which I intend to keep in my saddle bag so my plan was to mount the Igaro on the rear of my seat post. My initial intention had been to snip the wire running to the rear light and solder in a wire that would run up to the seat post from the bottom bracket. As I was going through this I realised this would not work if I had the light switched off!

I ended up snipping the main wire from the light to the Dynamo hub  about 3/4 of the way up the fork and soldering in the additional wire from there (I am not gifted with excess talents in the soldering department but I can solder a few wires together). I re-taped the wire to the forks and ran it up through the bracket of the light and then followed the run of the rear light wire along the down tube and up the seat tube.

The Igaro sits nicely on the back of the seat post and the wire and USB plug can just reach around into the Super C  Audax saddle bag.

I tested it briefly with a ride around the supermarket car park after closing time and I was surprised how slow I could be moving for the charging to start. It was charging my Galaxy S5 at all times while I was moving and it made no difference if I had my lights on or not.

I will update this later in the week once I have had a longer ride in more 'real world' conditions trying to charge the 25,000 mah power bank which is completely drained at home.

Perhaps a 3.2mm piggyback connector to connect to the front light AC in? We fit the connectors properly (crimped, soldered, wrapped) which would mean a third product line to go alongside the Shimano/SP and SON offerings. It could be time to break out the D1 power cable with a 2.1mm power socket to handle the Shimano/SP and SON and B&M 3.2mm spade connections people require.

Having lights on may appear to make no difference but it will. Some USB devices will turn off, others will charge very slowly by switching to 100mA USBv1 load - which will actually result in a slow discharge with the screen on. It also depends on how bright the lights are.

There's no free power I'm afraid and modern front LED lamps tend to suck it up. Today I ran an Xperia Z3 at a 0.95A charge rate at 16kph and it was impossible to continue charging it with a 30lux front light on (and a 0.5W rear).

3. B&M 3.2mm piggyback spades on short cable (D1 joins at front light, dynamo connects at front light).

Rather than having three product lines (we have two already) a breakaway cable like that attached would allow for various leads to be made up and a single product line. It sounds like the way forward.

I'm glad I haven't tried to fit my D1 yet, as I now realise I'm getting rather confused working out how it will fit with the front and rear lights. At the moment, I have a SON 28 in the front wheel, and a B&M IQ-X front light (with handlebar bracket) and Secula Plus rear light to fit, together with the D1. I want to have the D1 located at the rear of the bike. I think I need to do the following, but have some questions:

1. Connect IQ-X to SON 28, and cut the wire somewhere convenient near the head tube
2. Fit some sort of connector block, with input from wire connected to dynamo, and 2 outputs; front light and D1
3. Fit rear light cable to output from IQ-X
4. Run rear light cable and D1 cables together down down tube, with D1 cable going up seat tube, and rear light cable going to rear axle and up mudguard stay

Assuming that is sensible, my questions are:

A. What connector block should I use, and what size? As it is at the front of the bike, something with a tidy appearance is preferred.
B. Does the connector block need to be waterproofed - might also make for a neater appearance?
C. What purpose would the waterproof screw have ... could that be the connector block? Or would the waterproof screw just be between the D1 and the connector block, to aid removal of either the D1 or the front light separately?

Sorry if these are noddy questions, but my wiring knowledge is on a par with Oscar's dad - except I do have a soldering iron and can use it.

Quick n dirty review, hopefully more to follow at the weekend after a longer ride.

It arrived very quickly - ordered Friday PM and arrived Saturday morning.

It's very compact. I've used a couple of others and they've been pretty bulky. I hated the Dahon Biologic Reecharge (full rant here (https://yacf.co.uk/forum/index.php?topic=51443.msg1074471#msg1074471)), and I've been quite happy with a B&M EWerk, though it's overkill for my current purposes, which are charging a Garmin and a phone, plus occasionally a cache battery.

I wired the Igaro to the rear light output from my front light just so I could trial it on this morning's ride, and tucked it away in my top tube bag. Not ideal, but it sat there quite happily, and on the way back I used it to charge my phone, which task it performed quite satisfactorily.

So far, I like how compact and simple it is. When I get chance I'll attach it somewhere unobtrusive for a fuller test.

Thanks for that, makes sense.

My usage will pretty much be to charge a Cache Battery in the saddle bag which I will then in turn use to charge the phone as the need arises. The cache battery will be used to top up my phone and emergency lighting as required so as long as the Igaro D1 can put something back into the Cache Battery during a days riding I will be more than happy that it serves the purpose.

I've been quite happy with a B&M EWerk, though it's overkill for my current purposes, which are charging a Garmin and a phone, plus occasionally a cache battery.

I've got a USB-Werk, after giving up on developing my own design any further (I had a working prototype that was admirably efficient, but I'm rubbish at mechanical design, and in the time I'd procrastinated over how best to make the thing small, robust and waterproof, B&M had come out with a decent solution that was much cheaper than I'd ever be able to manage as a one-off).  It's worked well enough for keeping a cache battery topped up while touring, and doesn't need to be out in the airflow (it lives in my luggage with other electronics and valuables, and I plug it into a Tamiya connector on the bike when I'm using it).

The real advantage of the Igaro as I see it is for people who want to power an internal-battery GPS (or rechargeable light, or smartphone doing navigation duty) from the dynamo directly.  It's small and neat, which is ideal for semi-permanent mounting somewhere on the bike.

I should mention the USB Doctor inline voltage/current readers have around a 0.3v voltage drop over what they report, ideally the D1 voltage going out is 4.75v. This can go lower to aid low speed performance as most USB devices are happy with a few hundred millivolts out of spec, but with the USB doctor on top that may push it too far and cause the USB device (phone etc) to reset.

I received my charging unit last week. Since then I've been carrying out some tests over the same distance.


1. Phone on normal mode - charged up 16% in about 55 mins
2. Phone on normal mode with gps running on full brightness  - no charge
3. Phone on flight mode with gps running with a low screen - charged at 15%

I was also running my 40lux dynamo light which at all times was dimmed by about 30% ( including downhill) .

Fitting, I bored out the connector hole to allow the cables in parallel , this took no effort hardly needed a drill. I didn't fix to toptube  etc but cable-tied it to a an existing cable  , which I thought worked  well as the unit is unobstrusive .

My dynamo is old got it in 2009 a cheap one which may explain the light dimming. That said  I was happy with the amount of charge I got and can easily see this working with my Garmin so that at night I would be happy with the  7 or so hours of true darkness for the Garmin to cope on its own. To top up during the day.

In  conclusion.

Good for charging , my not be ideal for both lighting and charging if needing light to see by ( light was fine for commuting)
I'd rather have a bored out connector block ( £ 2.00 from spa) than the form mounts which never worked(tape riped foam)
Packaging , could be a bit more professional ( hand written address, could mistake as brought from ebay ;-) )
Instructions , might be worth a pictorial diagram for those not familiar with the terms parallel etc
Will send pictures as I thought some of the unit was unduly exposed to elements.

All in all a thoroughly decent bit of kit.

I finally extracted my igaro d1 from the post office today having missed it's delivery last Friday and the sorting office mistakenly sending it to my local post office for me to collect, very kind of them but it's shut by the time I get home...

None of that is anything to do with igaro and opening the box everything is looks good.  As with last review I slightly opened up the holes in the connector block on my sp dynamo.  I used a 3 mm drill bit in my hand, no drill, and it took just a couple of minutes.  Twisted ends with light cable, reconnected block and plugged my phone (Sony M2 aqua) in and it charged spinning the front wheel by hand from about 10 km/h.  Turned lights on (cyo 60 lux and secula rear) and tried again, same thing happened although I'll expect a slower charging rate.

A couple of zip ties on the fork leg to keep the wire tidy and the device tucked between the back of the bar bag and the part of the bracket that is screwed into the bag and it's ready for a road test on the commute tomorrow.  I did try a couple of other mounting positions - the d1 is just too long to fit flush under my stem and on the side of the headtube would leave a loop of wire sticking out.  I may well mount it there and shorten the cables, but will see if any other options occur to me first.  Even with a bit of faffing over this it was no more than 20 minutes from opening the box to being ready.

I'll add some charging rates once I've ridden with it, but so far so good.


Edit: on commute today charged from about 8-9 km/h.  Phone battery charged at about 15% per hour with lights on, according to t'internet it's a 2300 maH battery inside the phone so if I understand it right, the average charging rate was very roughly 350mA.   I make that about half the dynamo output so I'm expecting some dimming of the lights, but the 60 lux cyo is not needed at full power on the lit roads.  I'll check another time how it affects lighting in dark country lanes. Charging was only interupted at very low speeds (stopping for junctions) and stayed on as I climbed a short 10% hill at 12 or 13 km/h.

I've now got my multimeter (the portapow one recommended by Kim upthread) and inital try out from other power sources tends to confirm the charging/discharging numbers given by the Ampere app.  However further testing of the maximum amperage available from the D1 will have to wait, as the dyno-equipped bike is poorly at the moment (lower headset sealed bearing suddenly started spewing brown gunk and is now very notchy)
Title: Re: Igaro D1 USB Dynamo Power Converter
Post by: igarocom on December 15, 2016, 11:24:23 pm
Thank you for feedback so far. Improvements which will be actioned are;

1. rubber mounts without stickers
2. larger zip tie
3. power and accessory ports
4. 3x power leads (SON/Shimano/B&M front light)
5. accessories; stability bank, solar panel in

On the topic of amperage there hasn't been any issues reported so far, however in order to keep the D1 as small as possible it may be that there is not enough capacitance (470uF) to ensure stability with some USB devices. The only device that has this exhibited this problem so far is the Sony Z3, while the similar Sony M4 Aqua is fine pulling 4.76V/0.74A at 18kph.

For devices that exhibit the same problem as the Z3 a 20,000uF capacitance bank which will fit up the fork crown will be offered as an accessory. D1's can be retrofitted with an accessory port - details will be on the website in a month's time. With the additional capacitance the Z3 charges at any speed and pulls 4.86V/0.95A at 18kph (Shimano 3N80, 700c).

All measurements are without lights.

Regards, Andrew

There is an efficiency drop to convert 5V to Li-ion (4.2V) charging and power is used by the phone at the same time. With a 60 lux light fighting for power, the D1 is performing very well for you.

The external capacitor is sealed, the black heatshrink is little more than for cosmetic purpose - it's fine if water gets in the top.

The main unit is sealed and filled - no water can get into it. If it could, we wouldn't be offering a lifetime warranty.  :thumbsup:

My D1 arrived promptly and was packed in a neat little cardboard box with no space for any Haribo   :(   The unit itself is tiny and has a slightly home made look to it.  This is merely an observation and not meant as a criticism.  In practice this helps it to blend in with the homemade nature of the rest of the wiring on my bike.

I installed it on my commuter bike which has a Shimano 3N72 dynohub in 26" wheels, a Philips Saferide (?) front light and a Herrmans H-track rear light.  The D1 input wires were twisted around the existing front light wires and were then re-inserted into the Shimano 'lego block' connector.  I am not sure how these connectors ever work but they just do.

(https://c1.staticflickr.com/1/328/31533063432_b22ef9be71_c.jpg) (https://flic.kr/p/Q3tcas)DSC01007 (https://flic.kr/p/Q3tcas) by jwilton634 (https://www.flickr.com/photos/22204998@N05/), on Flickr

I know that there is corrosion, mildew etc but the bike lives outside all year round so hopefully it will make a good testbed.

The wire was wrapped around the fork leg a couple of times with random cable ties used to hold it in place.  The D1 body was then tie wrapped to the head tube using the supplied mounts and temperamental double-sided tape.

(https://c2.staticflickr.com/1/65/30869079993_ce393fea38_c.jpg) (https://flic.kr/p/P2N728)DSC01008 (https://flic.kr/p/P2N728) by jwilton634 (https://www.flickr.com/photos/22204998@N05/), on Flickr

The USB output had a couple of bits of self adhesive foam stuck to it (from an Aldi puincture repair kit) and this meant that a cable tie could get purchase on it when it was attached to the stem.  It was angled down to (hopefully) allow the water to drain from it.

(https://c7.staticflickr.com/1/61/31642161166_b9461b8673_c.jpg) (https://flic.kr/p/Qd7m7S)DSC01010 (https://flic.kr/p/Qd7m7S) by jwilton634 (https://www.flickr.com/photos/22204998@N05/), on Flickr


The first ride was a 0730 commute so the lights were on.  I plugged a 'USB Charger Doctor' into the D1's USB socket to help monitor what was happening and then plugged in my Samsung Galaxy Ace4.  At just above walking speed the display came to life and the phone proceeded to take charge.  The front light flickered a little as the D1 cut in but I am quite happy to blame that on the lego block connector.  I was a bit surprised that the current display on the Charger Doctor seemed to be all over the place.  It updates about once per second and was flipping around between 0.1A and 0.6A.  I had not seen this sort of behaviour when charging from a computer or a wallwart USB.

In an attempt to take any USB negotiation confusion out of the system I then tried charging a 2600mAh powerpack but this gave similar results.

I contacted Andrew who rapidly responded to tell me that the voltage drop on the monitor was probably confusing the USB circuitry.  It would have been good to get some quantitative charging rates but as the devices were charging I wasn't too worried.

Further experiments this morning showed that with the bike lights off my Etrex 30X takes current at speeds above about 9kph.  My phone does so at speeds above about 11 kph.  These speeds increase by 1-2 kph if the lights are on.

When I have felt the D1 it has always been stone cold but I haven't really tested it with sustained high speed.

Now that my monitoring plans have been thwarted I need to do some longer rides to get a feel for how fast I am putting charge in.
Title: Re: Igaro D1 USB Dynamo Power Converter
Post by: thesloth on December 16, 2016, 02:12:55 pm
I've used my D1 on my commute every day this week charging various devices using the D1 in isolation and also testing the D1 in combination with the lights.

I use an SP PD-8 dynamo in a 26" wheel. It normally drives an Exposure Revo light and an Exposure Redeye rear light. The rear light is powered from an output on the Revo, rather than directly from the dynamo.

To wire up the D1 I split my existing cable from dynamo at the head tube and soldered the D1 cable (in parallel). I then sealed it all up with heatshrink. I inserted a small piece of cable tie to form a splint across the join to avoid any flexing at the weak point.
Overall a neat and unobtrusive join.
I will mostly change this at some point as I would like the option of being able to move the D1 between bikes and remove it when not required. I have ordered some of the waterproof connectors mentioned up thread.
A was able to fit the D1 out of the way under the stem.
I suppose my preference would be to be able to place it inside a top tube bag. I did note the warnings about overheating.
Unfortunately there aren't any alpine passes on my commute so I wasn't able to test this. I have one short hill where I reach up to about 50km/h for a minute or so. I checked the D1, but couldn't feel any heat at all.
That said it's out of the way under the stem, so I'm probably happy for it to remain there.
(https://c1.staticflickr.com/1/731/30837802704_bffd805ec3.jpg)

I don't think that it's a good idea to expose the USB output to the elements so I placed that inside the toptube back, along with the device being charged.

Here's a list of the devices that I was able to successfully charge and the impact that they had on the light.
It should be noted that the Exposure Revo is a very bright light (800 lumen) and therefore probably draws a lot of current.

Garmin Edge 800: (My commute is 20km - 25km/h avg, 48min moving, 1hr 2min total) Commute without the lights took the Garmin from 6% to 35%.  Backlight was on high.
The same commute done with the lights on took it from 35% to 68%. There was no real noticeable drop in the light output while the D1 was connected.

Exposure joystick: Charged ok. It takes a lot of power from the light (estimate at least 75% only one LED functions)

Samsung Galaxy S5: Charged ok. It takes power from the light (estimate at least 50% only two LED function)

Olympus TG-850 camera: Charged ok. It takes a lot of power from the light (estimate at least 75% only one LED functions)

iPhone 6: Charged ok. It takes a lot of power from the light (estimate at least 75% only one LED functions)

Lezyne Micro Drive rear light: Charged ok. It takes power from the light (estimate at least 50% only two LED function)


In summary I am very happy with the performance and form factor of this device. It's exactly what I was looking for.
My tests have proven that it can successfully charge all the devices that I am lightly to want on the road.

The only "mission critical" device is the Garmin and it's a bonus that it looks like I will be able to charge this at night while using the lights. The other things can be charged during the day. Even the most power hungry devices still allow the light to function enough for it to be used as a "be seen" light.

I will most likely get a cache battery with passthrough and use that to power the Garmin to stop it beeping and turning on the light when it looses power when stopped.

It looked like the charging kicked in at around 14km/h. I was using 26" wheels, so maybe a km or two faster is to be expected when using 700C.
As I mentioned I will most probably put a cable connector on the input wire and possibly also the output wire.
I would assume that the majority of people who have chosen a dynamo solution are comfortable with bit of basic electrical wiring. Everyone will have different requirements regarding wire lengths, routes, D1 & light locations so it would be difficult to make a solution that caters perfectly for all. For me I was happy to solder my own connections and have a good length of wire to work with. Offering a pluggable option ala e-werk might not be a bad idea though.
I also liked that the USB connector, which is the component most likely to fail is not integrated into the device like a Sinewave or one of the chargers integrated into the steerer tube. This should be easy for most to repair/replace and this has been identified and offered as a future service which is nice.

...the only downside to all this wizardry is that I will no longer be able to use the excuse of stopping somewhere for a rest to charge my devices.

Thank you for the discount Andrew. I'll provide an update in future once I've managed to live off it in the wild for a few days (not expected until the summer)

Correct. The dynamo can only output a finite amount of power. Depending on how fast you are going/what type of dynamo you have/what type of lights you have/the power requirements of device you are charging. If you are not producing enough power something has got to give.

The SP dynamo that I have (and something like a SON delux) is designed to be used with LED lights. I believe if you have a dynamo like a SON 28 they produce a lot more power.

That's what I thought and possibly an argument for using the B&M Luxos (yes I know some people including myself have had reliability problems) and not the D1.  When the Luxos is lit and you have something plugged into the USB output and you ride slowly (hill climbing is a good example) the red LED on the handlebar switch goes out to indicate the cache battery is flat but as far as I can tell it still powers the device connected to the USB.  I say "as far as I can tell" and I think I am right as often I am powering my Garmin E30 off the USB and if the external power fails the unit tells me. 

But the crucially point is that at no point does the light dim.  I'd far rather sacrifice USB power than maintain it at the expense of light brightness.

Or am I missing an important point?

That's a simple but not a complete solution. 

You can't charge a Garmin E30 as it runs on AA cells.  But it will take an external power source (USB in this scenario) which means you aren't chewing through the AA cells and (this is the best bit) the back light stays on when the unit is externally powered.  Very handy indeed at night, and I ride a lot in the dark.
Title: Re: Igaro D1 USB Dynamo Power Converter
Post by: Kim on December 16, 2016, 04:56:14 pm
Occupational hazard of using a charger that's independent from the lights.  It can't do much to prioritise lighting over USB power, except gracefully dropping out at low speeds.  The flip side of that is the non-linearity of both LEDs and the human eye: it takes quite a change in power to the lighting before there's a perceivable difference, so you can probably keep an eTrex ticking over without a perceivable effect.

Personally, this doesn't bother me, as my main use for USB power is to recharge a battery pack when touring, which is mostly a daytime activity.

I also do a lot of night riding. With a device with replaceable AA cells, I don't particularly want to use external power. You can ride a 400km with an E30 on a single pair of AA cells. Backlight on all the time of course makes this much shorter - so I don't do that.

I'd like to be able to record more data, such as using the Edge 1000. Or using my phone. But each of these has no replaceable batteries so I need to carry a fairly bulky Li-ion cache battery. By the sound of it the D1 can replace this with something smaller.

Yes I do sometimes use a power pack which can power the E30.  I have the Luxos USB plugged into the pack too which keeps it topped up.  But, the power pack requires the use of a bar bag which I don't always need.  Obviously I could find another power pack carrying solution like a top tube bag.

Sure, all that makes sense. 

Despite favouring the Luxos for my own usage (assuming the bloody thing doesn't fail - fingers crossed - I've been OK for a while) I think the  D1 seems to be an excellent solution for many riders.  Having choice is the key thing here.

Yes, sounds sensible if you're using a device with replaceable batteries. I was thinking in terms of my own set-up with an Edge 510 (non-replaceable battery).

Andrew made a good point upthread about power packs with pass through (eg Limefuel) - so you could have the D1 > power pack > Garmin in series. I thought my Anker power pack had this feature but I tested it and it doesn't.

E20 with backlight on low will last about 22 hours on a single set of AA's. Beware of having it plugged in to external power on the bike. I did that (all the time off a Luxos U)  and it wrecked the USB port and I had to get a reconditioned unit after it broke.  My preference now would be to plug in cheap charger to charge some AA and swap them over as required. If touring and you have access to a power socket at night you can of course just carry a charger to use in the evening.

Apologies for the 'thread hijack' but may I ask , did you mean the USB port on the Luxos or the E20? and in what manner did it get wrecked ? 
I've run my Vista off the Luxos USB for a long time now with no problems, and no doubt will on day have to move with the times and get an E20/E30, so I'm wonderign if there is something new I should be looking out for?

Sadly not.  I don't need any more chargers.  Indeed, I can barely ride a bike at the moment.

E20 with backlight on low will last about 22 hours on a single set of AA's. Beware of having it plugged in to external power on the bike. I did that (all the time off a Luxos U)  and it wrecked the USB port and I had to get a reconditioned unit after it broke.  My preference now would be to plug in cheap charger to charge some AA and swap them over as required. If touring and you have access to a power socket at night you can of course just carry a charger to use in the evening.
Apologies for the 'thread hijack' but may I ask , did you mean the USB port on the Luxos or the E20? and in what manner did it get wrecked ? 
I've run my Vista off the Luxos USB for a long time now with no problems, and no doubt will on day have to move with the times and get an E20/E30, so I'm wonderign if there is something new I should be looking out for?

The USB socket on the E20. A connection between the USB port and the circuit board clearly got damaged in the unit. It would no longer be detected by the PC or recognise when external power was connected.  The Luxos USB output continues to work and I charge the small lipstick battery chargers from time to time off it. Those chargers cost under £10 so no big deal if I need to replace them if the port connections fail.

OK - thanks.
I've had Etrex (HCx generation) USB ports fail, both completely, and failing just the data element - but not (AFAICR) though having them externally connected like this.  I do have mine  somewhat protected at both ends of the cable with bits of sugru in a bid to limit water ingress.

Hi Andrew,
I'm running a velological rim dynamo on my recumbent. Would be interested to know if the D1 would work with this ? I wouldn't be looking to run lights and charge at the same time, most likely be using to top up Garmin and a cache battery for I phone.

Micro USB is flimsy, it's important to use a 90 degree USB cable, to ensure it's not pulling on the port and that the cable isn't able to move.

Water must never be allowed into the device port when charging - the micro usb pins are tiny and electrolysis will eat them in no time at all.

We've put a bulk order in for these as they're reversible. You may wish to check them out:

The eTrex series still use *mini* USB.  Which is an even worse choice, in some ways (at least with micro USB the part most susceptible to mechanical damage is in the cable, not the socket), and similarly intolerant of getting wet.  Fortunately the eTrex also uses AA batteries, so there's no real need to feed it external power while riding.

Technically it's only rated to 1.5W, though reviews indicate it gives out more. The D1's digital monitoring may fail to work correctly due to the likely AC frequency difference over a hub dynamo so you may have intermittent power when setting off or slowing down (this may cause problems with some cache batteries and phones). If it doesn't work correctly just send it back - you'll only loose the £2.09 postage (assuming you're in the UK).

So my device was shipped 8th December arriving next day but I haven’t had much time to give it a try out until this weekend, so only 2 rides to test it out.
I decided to temporarily mount it on my main Audax bike, this already runs a SON dynamo and Busch + Müller IQ2 Luxos U light with a complimentary Toplight View Brake Plus Rear Light.  The more permanent plan is for this to be on my single speed bike as an alternative to having a Luxos U installed on that too.

I opted for the SON compatible piggy back spade connectors to save on faff for trying this device out.  They arrived attached to the D1 dynamo end of the cable.  Probably would be nice to have some heat shrink on them to neaten them up and dispel the worry of anything shorting them out.

Also in the box are some foam mounting bridges/spacers and a couple of black cable ties.
The unit itself is very light, there is an external capacitor mounted on a fly lead which is then held to the ‘out’ cable using heat shrink. in addition to the ‘in’, these enter in to the ends of the metal housing, the ends of which are sealed with heat shrink and some form of glue (epoxy/hot melt?). This heat shrink isn’t the most cosmetically pleasing solution giving a look more akin to a prototype device rather than a ‘retail’ unit, but appears so far to be functional for sealing the unit.

Installation:
Installation was quite easy, I just fitted my existing light wires to the piggy back portion of the D1 connectors, then pushed the whole piggy back assembly on to the connectors of the dynamo.

The cable was then fed up the fork following a similar spiral as the existing installation, a small cable tie ensuring the risk of any tyre rub on lose cable is avoided.

I managed to purchase the recumbent version of the IQ2 lamp, but in over a year I still haven’t got round to shortening the cable, so this bunch of cable made a good location to mount the D1 from, which was achieved using a couple of black cable ties.

This mounting location leaves the USB socket in a suitable position to sit inside my bar bag when fitted.

Try-Out 1:
The first run out with this was 70km ride with about 3 hours moving time, bike light on all the time.  The only thing I had to hand at the time to test was a 5000mAh power bank, this was showing 2/4 LEDs on the charge indicator, I will assume these relate linearly to the stored charge, so after the 3 hours of moving at an average of around 24kph, the power bank showed ¾ LEDs, so one could draw an assumed increase from 2500mAh to 3750mAh, so 1250mAh increase over 3 hours, circa 416mA of current provided over that time. (as a very, very rough estimate!)

Try-Out 2:
The second time out was the Santa Special 200km Audax, again with the bike lights on, here I have no real measure other than perhaps extrapolating from the battery level of the Garmin Edge 1000 it was powering.  I put the Garmin on charge when it was around 67% left, and in 2 hours it was up to 100%.  The standard Garmin Edge 1000 battery is 1100mAh, so that’s 33% in 2 hours@21kph ave (assuming 1% is 11mAh) then that’s 363mAh put in over 2 hours, so 181mA current drawn. 
The device then kept the Garmin charged for the remainder of the 7 hours left of the ride (the exceptions being where I took the Garmin off the bike for control stops etc).  Remember, this current is an indication of what the Garmin required, not what is possible to be supplied by the D1, which could be a lot more.
I didn’t see any noticeable dimming of my lights but once the Garmin was charged, there is minimal current draw to maintain it, the data from my Garmin prior to charging it shows it is about 127mA current, but that will depend on what you are doing with it (screens, sensors etc).

Conclusions:
Early doors, but it appears to do what it says on the tin, it seems happy to provide 400mA of current and will happily keep the Garmin charged. Obviously the caveat here is the assumptions in my calculations of course!

Thanks for the opportunity to own and provide a review, hope it helps :)

Thanks for the feedback. Regarding your points;

I like the solution B&M have for the attachment of their USB connector, using the weather proof barrel connector, this allows the charger lead to be left with its cap installed and less obvious about what it is, so perhaps less chance of being stolen?  Also this facilitates different lead types or lengths to be added.

>> it's coming up, in the form of a power and accessory port (retrofittable)

Some heatshrink on the piggy back connectors would be a good idea.

>> agreed, we heatshrink them in two places but need a little over the top where it's been soldered. This will be done for the SON power lead.

I recognise there might be a weight penalty to this, but perhaps consider epoxy potting the D1 internally and using heat shrink as strain relief for the cables rather than the present glue/heat shrink solution?

>> we do potty the inside and that is heat shrink for strain relief. It's actually heat shrink with a glue liner which acts as a second water barrier and prevents it falling off the D1 body (a problem we found during assembly). It's not the neatest due to the shrinkage and glue seepage but it works very well.

As with others on this thread, I received an Igaro D1 2 days after ordering, neatly packaged with the simple installation instructions. I installed mine without the foam supports, just cable tied directly to the side of the head tune, the heat shrink at the ends of the device providing adequate ‘support’.

Dynamo is an SP8 in a 700C wheel.

Devices tested:
•   Garmin etrex HCX Vista
•   Olympus TG850
•   Pebble smartstick battery pack (2,800mAh, 1A charge)
•   Ravpower RP-PB17 battery pack (6,700mAh, 2A charge)

All charged OK from the Igaro D1 when directly connected to the dynamo. Charging started about 1s after moving, and above 10km/h. This is the most likely use for me, to charge devices during the day when lights are not needed. I would not normally run the etrex off anything other than AA batteries (getting a good 40 hours from AA lithiums which I use for 600km+ events), but it did run quite happily when above 10km/h (but the switch back to batteries when stopping for junctions, etc. would annoy me).

The second test was with the Igaro wired in parallel with my light, which is a ‘homemade’ Philips Saferide 80 with battery electronics removed and replaced with the electronics from a Cyo; this draws 1A 6V at about 30km/h (and is still by the far the best dynamo light I have ever seen). This test was conducted on rollers in my dark garage, at 30km/h, with a light meter fixed to the garage door:
•   etrex worked fine and there was no reduction in light intensity, which is what you would expect with such a small current draw by the etrex.
•   Pebble smartstick reduced the light intensity to about 80% of the intensity when nothing was connected to the Igaro USB output.
•   Ravpower battery pack reduced light intensity to about 10% intensity when nothing was connected to the Igaro USB output.

I have not attempted to measure the current provided by the Igaro to any of these devices. From this result with a 6W front light, anything drawing any significant current from the Igaro would not be a workable solution for me, but as mentioned about, that is not a use case that I would employ.

After this short testing, I did notice that the Igaro was quite warm to the touch, maybe 50°C (no airflow on the rollers), which confirms the FAQ not to put it in a bar bag.

I have used it on my daily commute for a few days, to charge the Pebble Smartstick (easiest thing to use), which it seems to have done quite happily. With an air temperature of 3-5°C I would say that the Igaro is at about 20°C when I arrive at work after 25 minutes. A couple of times I have run it with nothing connected to the USB outlet, but the Igaro still connected to the dynamo. To my surprise, it has also ended up at a similar temperature. It would be interesting to know how it would fair in warmer air conditions, for example the 34°C I had in Provence in September.

In terms of use, if I was going to mount this permanently I would run a single cable from the dynamo to close to my front light, and then insert a switch to allow me to switch power to either the light or the Igaro (in fact my light has a 3 position switch of which only 2 are used, so it would be easy to run the Igaro cable from the light using the 3rd position to give off or front light or Igaro with the light switch.

I have not used any other dynamo USB chargers, but I like the look of the form factor, robustness and apparent smooth output of the Igaro. My only question at the moment is the amount of heat generated with no load attached.

I think you mean:-

"Pebble smartstick reduced the light intensity to about 80% intensity when connected to the Igaro."

Heat

There is an electrical trade-off for over-voltage protection, either;

a) parallel clamp - which offers greater efficiency when device is used (which is why so many of you are having success running the D1 alongside lights) or
b) a load based clamp which induces a voltage drop penalty (works out at around a 18% efficiency drop) but which produces no heat when no device is used.

The D1 had extensive research and real-life testing prior to it's final circuitry being mass produced and option a. was found to have the greatest success for most people. That does mean it's less suited for a small proportion of riders - those that don't run lights or a USB device and which ride faster than the average rider. Under these circumstances some power will be lost as heat. It is one of many considerations when designing these power converters. If we'd gone with b. there'd be people complaining their devices don't charge at lower speeds or that there's zero chance of charging with lights on.

Fortunately the eTrex also uses AA batteries, so there's no real need to feed it external power while riding.

I've found the same with the Edge 510, even though it has an internal battery - just plugging it in to a battery pack when stopped at controls is more than sufficient to keep it topped up for a 600.

In terms of charging things on the bike I have really simple needs, I don't even need that much power. I like many others have a Garmin Etrex for navigational duties as I like being able to use AA batteries (readily available and easy to store spares). However I had bought myself a Polar M400 Running / Cycling Watch which I use for tracking my performance data, this has an internal battery that's life when using the GPS is not that great, a fair trade off as it's not much bigger than a digital watch.

The D1 arrived a couple of days after I ordered and on first impressions I was surprised how small it is. I mounted it on the side of my head tube with the foam mounts and ran the cable down the fork where I twisted the ends together with the lead for my lamp. For comparisons sake the bike I've fitted it to has an Exposure Revo lighting system which comes with an exposure branded SP dynamo. This is different to my other bikes which have SON units but this is my daily commuter stead so the best to test the D1 on.

I modified a Polar handlebar mount and a short micro usb lead to allow me to plug the watch in while riding and gave it a go, alas the watch has no power or charging indicator but on arrival at work some 24km later it had gone from 50% to 100%.  As I live in the Cotswold's I had the opportunity (read no choice whatsoever) to ride up and ride down some pretty steep inclines.  When climbing my observations show that anything below about 10km /h results in no power and the 50km /h plus descents did not result in any undue overheating.

I decided to make the fitting more permanent by making a dynamo tail from a short length of Schmidt coaxial dynamo cable and connecting the lamp and D1 at the top of the fork with a solder joint insulated with shrink wrap cable outer.

Am I happy with the unit, yes it meets my simple needs and looks unobtrusive on the bike though there is enough wire and mounts on this ride no one would notice, At this point I'm considering buying another one to go on my tourer and possibly one for the tandem rather than make plugs and things to swap them around.

Frankly it just works.

A picture if possible would be great.  :thumbsup:

We have power and accessory ports coming soon which would be a cheaper way for you to swap over the unit between bikes. We'll have a service to retro fit them to your existing D1 too. ETA about a month.

My Igaro D1 Review

My Igaro was delivered within 2 days of ordering,  It came packaged in a small carboard box and came complete with fitting instructions and a FAQ.  I ordered the version for the Shimano Hub as I wanted the bare wires rather than piggy back spade connectors.

It’s taken me a while to get around to fitting the unit.  To cut a long story a bit shorter - The original plan was to fit it to my commuter to test and write this review and then re-fit it to it’s intended home on my Audax bike.  However things changed when I decided that my Luxos U was getting too unreliable.  It kept randomly switching itself on and the light was flashing while on standlight.  I’m already on my second lamp after a warranty replacement for the first one and my Audax bike needs to be reliable.
So I decided to bite the bullet and replace the Luxos with an B&M IQ-X and while I was changing and rewiring my new lamp, I might as well wire in the Igaro too. 

So the full set up is a SON delux hub built into a 700c wheel, a B&M IQ-X front lamp and a secular rear lamp & now of course the Igaro D1.  I will be mostly using it to charge my Garmin 1000, occasionally my Sony Xperia Z3 Compact phone & even less occasionally my Anker powerbank.

I decided that the best place for the Igaro was under my stem.  I run a long 13cm stem and it fitted under there quite nicely.  I used the supplied self-adhesive sponge mounts and secured the Igaro to the mounts and the stem with a couple of zip ties.  I only need the USB wires to reach a few centimetres to the Garmin on my stem or the phone or powerbank in my top tube bag.  So I used the shortest micro USB lead I could find, but there was still an excess of cable, so I coiled the excess around and secured it to my stem with another zip tie.  In the future I’m thinking I’ll chop off the USB socket and wire in a shorter micro USB cable instead (everything I’m likely to charge will be via micro USB).

I ran the wires for both the Igaro and the IQ-X down to the front hub where I terminated them directly into 2 spade connectors for the SON hub.  On my set up, the wires of the Igaro were just long enough to reach from my stem to the hub (I’ll edit this post later when I get home and add my bar to hub height here).  The wires were placed next to each other and taped to the inside of the fork leg with insulation tape and secured at the top and bottom with a zip tie to stop the tape unpeeling.  The bottom end of the wires and the spades were covered in heatshrink to give them some protection.  Using one pair of spades rather than piggy back spades gives a neater appearance, no different to running the lamp on its own and doesn’t interfere with wheel removal, but does not give the flexibility of being able to remove the charger from the lamp.

A quick 2 minute ride up and down the street showed that everything was working and that the unit was delivering charge to my Garmin at anything above about 12-14kph without the lights on.  With the lights on, I was getting charge, but the lights were flickering, but it was also trying to charge the standlight capacitors of both front and rear lamps too at this point.  A longer ride will tell me more. 

I knew I was going to be testing the Igaro, so before I removed the Luxos from the bike I did a benchmark test where I timed how long it took to charge my Garmin 1000 while out on a typical ride with no significant stops (i.e. only waiting at T junctions etc).  I then repeated the test with the Igaro. Both tests were done without lights on.
The test was to charge my Garmin from 40% to 100%, in both cases the screen brightness was set to 2 bars, displaying the map screen and navigating to a location and route recalculation switched on.  I had it navigating me to home, but I wasn’t heading that way so it was regularly recalculating.
What I found was:-

Luxos U. 
Time to charge from 40-100%: 1hr 15min
Distance covered: 32.6km
Average moving speed: 25.9km/h

Igaro.
Time to charge from 40-100%: 1hr 18min
Distance covered: 39.7km
Average moving speed: 30.3km/h

I consider these two results to be essentially the same.  In that they both took a similar length of time to charge my Garmin.  The 3 minute difference between the Luxos and Igaro is well within the accuracy of my timings and the battery reporting of the Garmin.  Also note that the cache battery of the Luxos was already full charged when I started that test.  I don’t think the different average speeds mattered too much as I’m assuming that I’m above the speed needed to for the hub to give the maximum electrical power, or maybe it’s the limit of the current that can be taken by the Garmin.

Other observations while out on the road.  I found that I could run my lights and charge the Garmin while the Garmin’s charge was above about 95%, although there was a slight reduction in the lamp brightness which was only really noticeable when plugging/unplugging the charging lead while riding along.  Below 95% charge on the Garmin the front light would flicker, even at highish speeds, i.e. above 30 kph.  This isn’t really a big deal, when using this bike I tend to keep the Garmin plugged in all the time anyway, so It would usually be on full charge when I switch the lights on.  The Luxos used to struggle with lights and charge too, the light beam would be much dimmer while charging and while powering the Garmin at 100%, more so than with the Igaro.  I’m asking a lot to be able to charge and run lights at the same time with my SON delux hub, I imagine a SON28 or Shimano would be better for this.

I also tested charging my phone.  This wasn’t a thorough test, I haven’t ridden in daylight enough recently for that, but I did ride with the lights off and the Igaro plugged into my phone for about 10 minutes at 25-30kph and noticed that during that time the battery had charged by about 3%.  I didn’t notice at what speed I needed to be riding at for charging to commence however.  I’m very impressed with this as the Luxos struggled to charge my phone, it would cycle from charge to not charge as the cache battery would discharge and recharge which was very in efficient at the back light would come on at each cycle.  The Igaro only seems to cycle the charge when I slow or stop which on a long ride would not be very often.

A tip with charging android phones is to use the “Solar Screen Off” app which vastly reduces (almost eliminates) the screen switching on when charge is connected/disconnected.

Overall , I’m impressed by the Igaro, it does what it says on the tin & seems to be a very efficient charger.  It’s a neat little unit which I can hide discretely under my stem.  I think my only criticism is the capacitor on the USB lead is a bit ugly/messy , I think I would rather have this located internally in the charger, even if this meant that the case of the unit was bigger, maybe there’s good reasons for this?   

I am thinking of shortening the USB lead and doing away with the female USB socket in favour of just a male micro USB plug.  Will this void the warranty?  Also Is the capacitor potted? Will I be able to solder a new cable to this or am I best cutting the cable and joining a micro USB plug on the end?

My Audax bike needs to be reliable, I could be in the middle of nowhere in the middle of the night. I’m very happy that I now have a system which due to the separate charging and lamp units I now have some redundancy built in.  In the (unlikely) event one of these fails, at least the other should keep working, this is less likely to be the case with all in one systems like the Luxos U

I’ll take some photos of my set up tomorrow in daylight and up load them to this thread.

Hi PeeJay,

The Garmin 1000 consumes low charging current so it's expected any unit will be able to power it. As you found out, when the current requirement nears the available dynamo power the extra efficiency of the D1 begins to matter. As you mention, this is even more problematic with a SON Delux.  :thumbsup:

Re: capacitor

Originally the D1 concept was to use several MLCC capacitors inside the tiny case, however performance testing exposed weaknesses in the MLCC's performance at higher capacities (I'll not go into it here). There is no other solution but to add extra capacitance externally to the case (or inside it but that would enlarge the case by quite a bit and there'd be a bit of unused space in there, plus Titanium costs quite a bit). The main reason for not adding electrolytic capacitors inside the case is reliability. They don't last forever, more so for this application as the dynamo hub gives out such low frequency AC they have a hard workout and that would have meant we couldn't offer a lifetime warranty. The D1 capacitor is the best there is, a Japanese unit with a 10X working life, and we estimate it will last 10-15 years before replacement is required. The further away the capacitor from the unit the worse the D1 performance will be. You could install a smaller 100uF capacitor in its place which in theory will allow for the main capacitor to be further away. Make sure this capacitor is minimum 25V rated and connected with correct polarity - failure to do so would likely end in the D1's destruction. As long as you get this right there shouldn't be a problem honouring the warranty.

I strongly recommend not replacing the USB port with a micro USB cable. These degrade very quickly when wet. Consider buying a short USB to micro cable (15cm's are possible) and using it as a sacrificial part.

http://www.ebay.co.uk/itm/15cm-Gold-Plate-USB-2-0-A-Male-left-Angle-to-Micro-Male-Right-Angle-Short-Cable-/321608143306

The D1 is as small as it gets without sacrificing every day performance. If you go ahead with changing the capacitor you may wish to consider boosting it to 20,000uF (2x 10,000uF 25V capacitors fit well under the fork crown). We'll be offering this as an accessory next month to boost high current out at low speed. It may however result in less power for lights. The capacitor fitted to the D1 generally gives the best overall outcome for most setups.

Hope that helps and many thanks for your review.

Andrew

Ordered mine late on Wednesday 7 Dec and very small package arrived on Sat 10 Dec after being posted on 8 Dec.  Very impressed thus far.

Opened package and very similar response to others who have posted thus far; albeit a little concern initially regarding the capacitor being slightly open to the elements and considered the use of black electrical tape, but then read reply at post #125 to a similar concern and realised all was well.  Remaining impressed.

Fitting was straight forward to a SON Deluxe and no more fiddlesome than existing SON connections to the light; agree that it might be worth having intermediate connectors that would also be good for a light only option.  Might use USB extension to lengthen cable to device and give the join a good wrap in tape to make it waterproof and allow the connector end to remain in the bar or top tube bag.  No idea how much losses would result in such additional connections but doubt whether it would be catastrophic!  Remaining happy with product.

Test was in daylight with Garmin 800 and all well.  Quick swap to external powerpack and charging took place.  Trying it with phone also resulted in charging.  As my intended use would be for charging in Garmin/powerpack/phone in daylight hours, as opposed to attempting charging when using the light, it meets my needs in every respect.

Overall, very happy and impressed with the product.  My comments very much reflect those of others who have reviewed the product and could no doubt be summed up by "wots not to like!"

Many thanks to Andrew at igaroo for both the product and fantastic discount.

A bit late getting round to this, I ordered at the last possible moment, then had to find time to pick up from the post office.

Review:

Fitting was a doddle, apart from initially peeling the tape off the foam spacers instead of peeling the cover off the tape. Despite that, it was pretty secure when fitted, but I added a cable tie as well just to be sure.

It was dark the first chance I had to take it out for a test ride, so I wasn't expecting much. Actually, I wasn't expecting anything: I have a Luxos U on the touring bike and that will charge, or run the light, but definitely not both together. So I was amazed when it started charging my phone almost straight away, even with both lights on.

In stop-start traffic the charging also stops and starts, which is to be expected as there's no buffer storage, but was a bit disconcerting at first - the Luxos has an internal battery which means it doesn't do that, but it also doesn't start supplying power for a while. When out of town the power cycling stopped and I checked how it affected the lighting. With the igaro D1 charging my phone the headlight was slightly dimmer, not enough to be a problem, but the light did flicker quite noticeably. I don't think I would use it in this way for long night rides, as I find the flickering very irritating, but it's good to know it's an option if needed.

The other thing that had concerned me was the fact that it is said to warm up when plugged in but not charging. This must mean it's drawing current, so will be adding drag even when nothing is being powered from the dynamo. A few minutes with the "wheel spinning test" shows that whatever power it's drawing the effect on drag is too small to be of any consequence.

Verdict: I'm incredibly impressed with the Igaro D1, it has far exceeded what I was expecting of it.

Equipment: Igaro D1; SON Classic; SON eDelux II; SON tail light; iPhone 6.

Post by: Manotea on December 28, 2016, 12:50:59 pm
My rather non-technical review based on one outing. :)

My dyno setup is an oldskool SON28 and a newskool B&M IQ-X, the 100 lux jobbe. I have a AAA battery powered rear light, and a AA powered GPS, and for the time being at least my main concern is to keep my phone charged on extended Audex events. The phone is a HTC One M8 with a 2600Mah battery. Under normal use it gets through about 75% charge daily.

Fitting the D1 was straightforward, using the D1 integral SON connector doubler and Zip tying the the D1 to the headtube. I don't have a bar/toptube bag for the phone so I ran a 1m USB cable along the top tube of the bike into my saddlebag where I stashed the phone. I put some tape round the USB connectors to weatherproof them, though that seemed rather redundant as the forecast was dry, and I was good to go. Easy.

I was interested in the D1's claims to deliver power with minimal losses which rather contrast from user reviews of the B&M Luxos U in particular. As it happens I'd had a MKII Luxos U for a while... I liked the light well enough but for various reasons (a long lay off riding/laziness/you know how it is...) I never got around to trialing the 'U' before I binned it because of failing electronics and corroded terminals. I'm hoping the metal bodied IQ-X will fare better.

I left home before dawn with my phone showing 25% charge and my light on. I immediately noticed the reduced brightness of the light, though it was hard to quantify because of the street lamps and damp rough tarmac roads round my way which seem to eat light. Once I reached the wild unlit country roads past Windsor (...)  I could better take stock and figured the light was in the 40-50 lux band, say equivalent to the soft unfocused light of the early Solidlight. Perfectly rideable but well off the hard bright beam of a fully powered IQ-X. I was ticking over around 25 and made a stop in Windsor - call it an hour moving time - to see how the charge was progressing. The charge had moved from 25% to to 35%, so it was working! I gave it another couple of hours of the same, and the charge move on to 55%. It was light by now so I turned the light off and also had the bright idea of turning the phone off, to see if that impacted the charge time (I had previously turned off off Wifi & BlueTooth though mobile data services were still enabled). I gave it another couple of hours and the charge moved on to 75%. At this point I disconnected the D1 to finish the journey. I'd like to report that without the additional power drain I immediately started riding 10kmph faster but I find the extra 'load' of the charging dynamo imperceptible.

So what are my conclusions?

Well, it demonstrably worked and was capable of powering a light and charging at the same time. My perception is the light output was about halved but still effective. I was generally moving around 20-25kmph (I ride fixed and am a cautious descender so rarely exceed ~45kmph even under ideal conditions). The light is B&M's latest and possibly more power hungry than others, so its plausible that lower spec'd lights might fare better whilst the D1 is charging but I really don't know; doubtless the efficiency of the electronics in the light have an impact. Like many others, the IQ-X has a capacitor to power standlight and daytime running lights.

Ref: Pickled Onions comments about flickering lights. The IQ-X flickers like mad at low speeds, say, <5kmph, but that stops as soon as the bike is moving properly. My perception is that the D1 had no impact on the lamp flickering at low speeds.

TBH given the impact on the light I felt somewhat underwhelmed by the charge rate of my phone. Doubtless I had unrealistic expectations but the D1 literature does emphasise higher charge rates compared to other products. Some real world examples would help here. My limited research indicates that for all these mobile charging technologies, including photo/solar, the reality is always, 'less than you might think', and the fact is my phone takes 'real-time' (hours...) to charge through a regular PC USB port. My Phone has a 2600Mah battery. Overall it was charging about 10% an hour. It didn't seem to make much difference whether the phone and/or bike light was on or not which I found surprising.

I don't know if the 1m cable I used - a regular USB to micro USB cable - had an impact on charge rate. If I had a bar/top tube bag then I would have used it, replacing the 1m cable with a small adaptor, though that's something else to lose on the road. I suspect the approach of using a cache battery that can be plugged straight into the D1 is the way to go.

In summary, I found the D1 compact, easy to fit and remove and I could comfortably charge my phone from cold during the day and have full power during the night, or run a phone like device, i.e., a gps, through the night with reduced but adequate lighting and that's exactly what I need for an upcoming tour where I'll not have time or inclination to worry about charging  kit at controls or buying additional batteries, so I'm a happy camper. Thank you, Andrew, for inviting us to take part in this review.

One very minor point... I suspect I'll tend to fit the D1 as needed, i.e., at most two or three times a year, and possibly to different bikes. On that basis, another set (or two) of the foam mounts would be useful.

I finally got around to fitting the unit today to my touring bike. I have an old Shimano DH-3N71 dynamo, with a newish B&M Cyo IQ Premium (and a battery rear light). I have been reading some of the other reviews so far and based on this one.....

1. Fitting
Keeping it simple, I intended to attach it in parallel to the cable powering the lights. I disconnected the lego block and opened it up. I took the cable ends of the light and the Igaro and twisted them together intending to insert them into the lego block but the holes were too small to take a pair of cables. So I took a 5 cm piece of household 2-core cable and a small connector block so the lego block was connected to one end and and the 2 pairs of wires connected to the block at the other.

.......I didn't bother fiddling around trying to wire both the light and the D1 into the lego block, but employed the same tactic of putting a new section of cable and connector block in. By effectively lengthening the cable run from dynamo to unit, this also gave me the opportunity to install the D1 in a different location to the recommended front of head tube position. I weighed up two possibilities - one being at the back of the tube (I have a nice CR badge at the front which I rather like and the head tube being tall has a space behind it which is just about long enough) and the other being underneath the handlebar/stem. I opted for the latter as to my mind it gave a neater look with the cable following the brake cable line, and the unit being virtually invisible. It seemed easy enough to cable tie the D1 into position (I will try to post a picture tomorrow). This means that I can neatly pop the USB end through the handlebar bracket when not in use which should keep it the right way up, and route it into the bag when in use for charging. 
@Andrew - is this likely to be OK longer term?  If so it would be really useful if the cable from the unit to the dynamo came a bit longer as standard, given it can easily be shortened if appropriate.

I've only done the wiring in a rough and ready way, if all goes OK will try to neaten up with crimps etc rather than the choc block connector wrapped in insulation tape and secured to the fork. However I wanted to give it a try before committing too much alteration of the existing lighting cable. Interesting dilemma as to whether to go for a permanently wired installation which I think would be neat, or to try something which allows for swapping between bikes (I have one with an SP dynamo).... given the comments earlier I think I will hedge my bets until I see what new options are available.

Like Manotea, my charging needs are really simple - just a phone, and particularly for cycle camping tours. However it's good to have something capable of charging a GPS should I succumb in the future.  I've only done one very short and cold ride today with the light on, so not really a fair trial yet - but I did manage to get my Motorola from 35% to 37% charge in just 2.5 miles so obviously something was happening. Impossible to tell whether the light was much dimmer as it was all on lit streets/paths. Hopefully I will get out for a daylight ride this week and will report back.

>> Additional mounts

Can be ordered on the website, we've implemented a proper shopping cart now to allow for pick 'n' mix.

>> Lights

I'm impressed the D1 works at all with such a powerful light. Even a 20 lux light will take much of the power away from the D1, enough to make charging a hit or miss depending on the USB device.

>> Charging Current

"Smart" USB devices (phones, powerbanks) do not redetect current availability. If your lights are on and the USB device detects a 300mA availability it will pick the next level down (i.e 250mA) and not rise above it. I wrote about this phenomenon here: http://thorncyclesforum.co.uk/index.php?topic=11774.0. Thus turning the lights off won't make any difference - you'd need to disconnect the power and reconnect it.

We have a stability bank accessory coming out soon (retrofittable and low priced) which will help some high current devices achieve a higher level of charge at higher speed by allowing the detection discussed above to move to a higher charge point at lower speed. It is expected lights will suffer however as electricity always takes the path of least resistance. Unfortunately there's just not enough juice coming out the dynamo to do everything.

Regards,

Andrew

Received the unit promptly from order, first reaction..where's the rest of it..it's tiny.
Mounted with a cyo plus lamp in place of Luxos U with SON 28/20. I have only temp assembled with the D1 taped to the front brake cable housing, but having tried that for a few rides I think that's actually quite a choice, so will leave in place. The good news is all devices charge as expected , Garmin 810, Samsung S7 and Anker Astro reserve battery. All still charge when moving briskly with the lamp on. Lamp seemed quite flickery with the Garmin though, and all stopped charging when the speed dropped down when climbing as expected.
This still leaves the same Garmin issue I have with the Luxos U. When externally powered the Garmin charges, but when the USB power supply falls the Garmin recognises this and stops....but it also the turns itself off after 15seconds (unless I respond to the screen prompt not too).. very annoying. I stress this the Garmins power management firmware not the Igaro per se. My approach is to carry on using the USB charger to charge an external reserve battery and then use that to feed the Garmin when needed, bit fiddly but it works - unless anyone has a better answer?
So a good functional little unit, and it frees me from the LuxosU which I think too complicated and that I don't really trust on a wet, windy , Welsh 600. Repeated BCM's have killed all my lighting systems at some point over the years, including variously 2x SON hubs, Schmidt Edelux lamp, B&M lamp, cateye battery lamps, and memorably the mounting bracket for a Hope1 backup light that unscrewed itself on the descent from Snowdon sending the light bouncing across the road at about 40mph.. that too some finding. Let's see what Igaro is like.

Hmm. Well, first impressions count, so let's start there. Sent and delivered promptly, though signed-for post meant I had to pick it up from the sorting office rather than it just dropping through my letterbox: as others have said, packaging details (handwritten address and the like) confirm that it's from a small company, which I quite like - personal service etc - but others might find less reassuring.

Looks - yes, it's tiny, and I confess to a touch of disappointment at the crimped rubber seals at each end of the main unit rather than the ostensibly cleaner look I was expecting from the pictures I'd seen online. (Of course, if I'd looked properly at the Igaro website rather than the (presumably) older photos at SJS, I'd have expected what I actually received ...) Like jiberjaber, I think a bit more heatshrink on the SON connectors would have looked better and been good - I always have an irrational fear that bare contacts so close together are going to go wrong in some indefinable way - probably that the electricity will leak out of them or something, just like it does from unshuttered mains sockets.

Installation - a supposedly temp job which will probably last for months - took minutes, admittedly with liberal use of insulating tape to hold the wiring to the fork leg, and a complete disregard for aesthetics. I've just zip-tied the unit to the headtube at present, relying on the rubber ends as a standoff rather than using the foam mounts supplied, and that seems fine - again, it's a functional look rather than one prettied up for the cameras.

As for use, I've not been riding enough to say much more than 'it works,' even toddling round town. Phone and GPS (an Etrex 30x) both receive power, and don't seem to dim the light (an old-school Cyo) noticeably. Of course, it's on-again off-again with low, town speeds: that's not a criticism, more an acknowledgement of expected behaviour, and use with a pass-through battery (as Andrew suggests) is the obvious counter - I have an Anker powerbank, though it's worth noting that the Etrex seems unhappy with the 'smart' USB ports and prefers connection to the dumb one. A couple of longer rides will give me a better feel for how this works out, and I'll update as appropriate.

One thing I've still not found a satisfactory solution for is what to do with the USB port when parked. This bike lives outside and, mindful of Andrew's warning about not allowing the connector to get wet, I've got a cut-down plastic bag taped over it. The Luxos U's rubber plug feels to me a more integrated response and I may get round to trying to make something neater out of Sugru (or more likely, an old inner-tube - I've got old tubes, I'll have to buy some Sugru ...).

I like the D1: it's easy to use, it's easy to install, and it's nice to have a power source that's independent of the light unit, so you can make your own choice of headlamp. It's also simple enough to transfer from bike to bike if that's important - with a plentiful supply of zip ties or insulating tape, you could have it off one bike and onto another inside five minutes.

But against that, I like the integrated nature of the Luxos I've got on my main bike, and the fact that its built-in cache battery smooths the supply to phone or GPS in most circumstances. Perhaps I'm lucky in that I haven't (yet?) had any of the trouble that other riders have reported with their Luxoses, perhaps I'm simply a fairly undemanding user. In any case, I'm lucky to have both a Luxos and a D1 available to use.

A small powerbank with passthrough will resolve the Garmin issue (i.e Limefuel L60x). Touring cyclists have been berating them for years over this 'feature' and they haven't listened. Eventually the Igaro G1 (D1 accessory) will be released which will give 4 minutes of stop power for smaller USB devices (specifically targeting the 8*0, 1000 etc Garmin units).

Thanks for everyone's comments and feedback. It's good to see and hear about the D1 doing its job. Little tweaks (we have a label printer but the niche demand hasn't warranted its use) will be incorporated. Going forward we will release;

1. power and accessory ports (a service will be on the website to retro fit if you want them) - eta 2 weeks
2. stability bank accessory - eta 2 weeks
3. internal mount bracket (hides D1 up the fork crown with USB cable out the top) - eta 8 weeks
4. solar panel input accessory - eta 8 weeks
4. Igaro G1 - 4-6 month

Thanks again,
Andrew

A quick review on the Igaro D1, given that there's been so many excellent reviews up thread and my knowledge on the more technical areas is quite limited compared the what others have written.

Overall
The Igaro D1 is a sleek device that provides on-the-bike charging in a fuss free manner.

My Previous Setup
Dynamo: Son 28
Front Light: IQ-X
Rear Light: Secula Plus

Positive Thoughts
Purchase experience and delivery was very pleasant, the device arriving in 2 days.
For a simple setup, the device would be easy to install.
The device worked as expected, charging a Garmin 820 on a trial ride without issue.
The device is small and has a pleasing appearance, therefore getting a neat installation on tubing is not too difficult.

Food for Thought
My initial intention was to mount the Igaro D1 at the rear of the bike, but I've not been able to work out how I should cut my front light wire to fit some sort of connector to allow the Igaro D1 and front light to operate in parallel. This is obviously an unconnected issue to the standard fitting and functionality of the Igaro D1, but the provision of guidance (perhaps in the FAQ) on how to install mid-wire rather than at the dynamo would be useful, including how to achieve this and what parts would be required. For now, I have temporarily attached at the dynamo.

What's next
I've only used the Igaro D1 on a single trial ride. Over the coming months I will be using it on rides of ever increasing distances, and fully expect it to replace the battery pack that I would usually carry on rides of 300km and upwards for keeping my Garmin charged.

Hopefully I will get out for a daylight ride this week and will report back.
I did in fact go out last week but have been a bit slack about reporting back. I only cycled about 14 miles and it was a real pootle around local roads and the Olympic Park so I didn't spend much time riding above about 10-11 mph. Even so I managed to charge my phone from 24% to 37% which seemed OK to me. Any half day ride, especially one at slightly higher speed should be enough to keep it topped up.

I am still interested in a longer cable on the dynamo side and would be happy to pay for a retrofit if it was available....any chance of this please so I can tidy up my wiring? I don't think any of the options mentioned in Andrew's last post would really be of use to me (although I am sure they will be to others).

First apologies for the delay in writing a review - I've been off the road due to a bout of flu. I've now managed two short rides this weekend and have set out initial thoughts below. I'll also add them to my bike and wheel blog, with pictures, at the weekend, as well as updating when I've done dome longer rides.

Ordering, delivery and first impressions
Simple and straightforward. I submitted an order on the website and the unit arrived in it's little box a couple of days later. My first impression was one of delighted surprise at how small it actually is and also how nice it looked in it's plain titanium case. Unassuming and very much form following function.

Fitting
Fitting was very straightforward. I simply ensured that I had enough bare wire and twisted the ends together with my front light wires, and then pushed them through the Shutter Precision/Shimano lego block. A bit of insulation tape to help route the cable up the fork leg and then to hold the D1 to the front of the headtube on my GF Ti - nice matching colour, and practically not at all noticeable. Worth pointing out that the cable ties wouldn't have gone around the big head tube, but that was fine in my case. This bike is in working trim and insulation tape is 'de rigeur'.

Set up
For completeness, and because there are a lot of tests using the SP PV8, I fitted the D1 to my GF Ti with an SV9 dynamo hub, Schmidt Edelux 2 and B&M Secula Plus. The SV9 is a tiny hub that doesn't meet the German regs in a 700c wheel, but does in a 20 inch wheel. The Shutter Precision website helpfully suggests that, 'You can just pedal 1.7km/h faster...' I was particularly interested in whether there would be any surplus power available to charge with the lights on at the same time - possibly asking a bit much - as well as what charge rate can be delivered without lights.

The usb leadout from the D1 is then fed past the headtube and into a small Restrap frame bag that I use to hold electronics and bits. The bag has a dynamo cable port, so that bit was easy too and it should keep the socket dryish.

Test rides
So far only two test rides. One very short and a slightly longer ride today.

Ride 1: I rode just over 6 miles around town with only the D1 in use, charging my work iphone 6. The D1 charged fast enough to add 10% to the charge position of the iphone, based on a battery monitor app. I was actually quite impressed by the speed of charge and only heard the phone 'bleep' to mark the end of charging when slowing right down.

Ride 2: I started this ride and did 15 miles at just over 15mph average with the lights on and the iphone charging. The charge status of the phone increased by only 2%, suggesting that the lights are power hungry enough that the dynamo cannot really supply sufficient power (or at least the voltage curve is such that...) to support significant charging at the same time. I then switch off the lights and rode the 7.5 miles home at a lower speed (into the wind) and found the iphone charge status had increased by 11%. Again, a very positive charge rate absent the lights.

Coming tests
I've ordered a usb charge meter so I can see what actual current is being put out by the D1 and will aim to use it on some longer rides. I've got a 3,000 and a 10,000 maH powerpack that I've allowed to discharge so I can test the D1 into those. The 10,000maH pack has pass through charging as well, so that will be a further test. Depending on the weather, some of this should happen in January - weather because the wind today interacted with the 30mm rims, 28mm tyres and guards on the GF Ti to make some gusts pretty terrifying, so the guards and big tyres are coming off.


Conclusion
I'm really pleased with the D1. It appears to work very well, and certainly much better than the usb-werk I had before. One positive is that I had no light cycling/flashing with the D1 today, it just didn't charge. The usb-werk and my (then) exposure revo were an unhappy combination with moments of unpredictable darkness. The charge rate appears useful and over a long ride I am comfortable that it would keep a powerbank charged, allowing continued used of phone and Garmin on tour for example. I suspect this is the main purpose and is one that I will likely adopt as well (look out for my trailer project...)

Andrew, thanks for the offer to test and review the unit. It seems to me to the most useful available at present and is also nicely and functionally put together. The accessories that you are developing with be really useful as well to those with more than one dynamo equipped bike and other wider needs. I hope the project goes well.

Regards

Mike

Sorry,  bit slow posting this,  but further to my review upthread ^^^^,  I thought I'd just add a photo of my Igaro d1 installation.   

(http://i57.photobucket.com/albums/g237/Pee_Jay_1/Mobile%20Uploads/DSC_0985_zpsppcgg2si.jpg)

This is of the Igaro zip tied to the underside of my (13cm) stem,  I'm using the supplied foam mounts here too.   The unit is secured with 2 zip ties and then a further 2 to tidy up the USB cable and secure the socket to the side of the stem.   I've then used a short micro USB cable with a 90 degree bend to plug into the port on the edge 1000.   I'm really pleased with the way it mounts here - it's practically invisible from above.

Finally in a position to post review. Delay caused by needing to ride Rapha Festive 500 on three wheels (trike currently doesn't have dyno hub and couldn't 'borrow' a wheel from another machine as it's on 26".

Further delay caused by an issue on the Condor where the Igaro D1 is installed.  Issue found and sorted.

I must be the final review of the Igaro.  My testing is in line with what everyone else has said.  The Igaro is small and delivers what it says it does with no fuss.  Being independent from the light is great.  I like the way you can switch between the various connector ends as it allows a variety of devices to be charged and covers off that the Garmin Edge range use both micro and mini USB.

My test was over my commute to work.  5 days and 450km with two returns in the rain flung in for good measure.  The Igaro worked brilliantly particularly given that I gave it my Edge 1000 to feed rather than the easier option of the 810.  Riding along without worry that the GPS would run out of power was brilliant.

As said up thread, if you plug in the GPS with minimum of 95% power the light works with zero issues with minimum loss of brightness.  If you want the GPS to be charged up from say 65% of power plus run the light, you will have a flashing light whilst the dyno hub / Igaro gets the GPS up to about 96% power then the light will resume normal service.

For value for money, simplicity and so far reliability a big thumbs up.

If you order the SON version, it will come with a pair of these piggyback connectors (https://www.sjscycles.co.uk/lighting-spares/wurth-cable-connector-noninsulated-63mm-female-with-piggyback-connector-x-1/) on the cable.
You take the light connectors off the hub and fit them to the spades on the piggyback connectors, the plug the piggyback connectors into the hub.

Aye - you end up with two cables running up the fork, one to the lamp, then one to the D1 (most likely mounted on stem or headtube) which then in turn has a further short cable to the trailing USB socket.

We have a stability bank accessory coming out soon (retrofittable and low priced) which will help some high current devices achieve a higher level of charge at higher speed by allowing the detection discussed above to move to a higher charge point at lower speed.

Any news on that?
I did a bit more testing today (with a portapow meter in the loop) charging both a phone and a cache battery and I'm consistently getting more (about 50% more) amps out of the Luxos with its cache battery than out of the D1.

You will, the Luxos uses the same NIMH batteries as the USB Werk - it will give you 1A when the batteries are charged and depleting, then zero while they are charging.

It's out (see website).

It's supplied with the "NC-17 Connect Appconn GT#1" (what a mouthful), an "all the bells & whistles" German power converter that uses an 18650 as a buffer and has an associated smartphone app that does things like count the dynohub pulses to measure distance (google translate magazine review (https://translate.google.co.uk/translate?hl=en&sl=de&u=http://www.bike-magazin.de/mtb_news/teile_zubehoer/neuheit-2016-nc-17-connect-appcon-gt1/a32761.html&prev=search)).

Not sure about that one.  I mean, front lights generally come with a long trailing wire to connect to the hub, and only have spade connectors on the rear light output (using that would mean you'd need to have the light switched on, drawing power).  Sure, some of us have fitted spade connectors on the input closer to the light to extend the cable run for an unusually shaped bike, but if we're capable of doing that, we wouldn't have a problem fitting our own connectors to the unterminated cable...

The thought (i.e. my thought) behind the connector block with spades was that putting spade connectors on a B+M light is a one off job, and if you also have piggyback connectors on the D1, you can fit either light or convertor or both, and swap back and forth freely with nothing other than keeping the cables tidy to worry about.

This is an interesting thought. I now have one bike with a Shimano dynohub and one bike with a Schmidt SON. I haven't bought an Igaro yet but it's on my shopping list and I've been mulling over the problem of how to swap it easily between the two bikes. The other solution is Kim's idea of using Tamiya connectors. I then got on to wondering how the lights would connect in this arrangement but I googled and found there is such a thing as a Tamiya parallel Y-connector.

The other other solution is to buy a second Igaro, but I'd prefer a cheaper option for now.

No need for that (unless you want to be able to move the lights around too).  I just connect the light and the dynamo in parallel to the back of a female Tamiya.

So I had my one and only issue so far with the Igaro D1 - Garmin was down to 40% battery on Saturday's audax, so pulled out a lead and plugged in the Garmin to the D1.  Nothing... no charging  :o  I still had a good few hours left to ride and the Garmin was my guide to getting back to the finish...  :facepalm:

I was riding along trying to think about what was the potential issue, lead? Garmin USB socket? D1?

Luckily I had put a small USB battery bank in my rack pack, so I was able to test out my assumption it was the USB lead I was using... it wasn't so I was able to get some charge in to the Garmin and made a note to investigate the D1.

I managed to take a look today and after a test ride, identified it was the power in cable where it was soldered to the piggy back connector - though there was no physical evidence of a broken cable, it eventually came away in my hand with a bit of encouragement.  I've since re soldered it back on and all appear to be OK. 

I took the opportunity to put a GPS logger on the power line as I was riding up and down testing but unfortunately the GPS part decided not to log, however I can say that the charging current on the Garmin Edge 1000 is about 375mA peak.

I also noted that with the IQX on, there was a good 4kph difference between powering the USB & not powering it compared with the IQX off - unfortunately no GPS log to record the speed vrs voltage/current I'm afraid.. If I get bored I might get round to putting the logger on the dynamo output and do some more comparison tests.

ETA: I would add my decision not to splice cables but use the already fitted piggy back connectors on the D1 was vindicated in that I still had working lights even though the D1 wasn't getting power...

Back on the bike after Black Ice Wednesday 8 weeks ago. As the baby cable to hook the Garmin Edge 810 to the Iggy had been organised during my extended sofa sit decided it was time to test this GPS rather than the Garmin Edge 1000.

Unlike the 1000 who loves the Iggy, the 810'positively hates it. Tried both the baby cable and my standard. Star Tech 3' cable. Both cause the Garmin to power down due to loss of external power. The longer cable does this more frequently, not just when you stop as per the baby cable. On both rides to work this has driven me so crazy that I've stopped to unhook the 810 from the Iggy.

Is there a solution to this other than putting a powermonkey between the 810 and the connection point with the Iggy? I'd prefer not to do this as it isn't a very good solution for the trike but would work OK with the two wheeled Condor.

Try a ride with the 810 using just the powermonkey and the cables you used before, to see if that gives power losses too.
If it does, it would probably be the USB port on the 810 starting to get flaky.

Many thanks. Will do and report back. Have noticed that using the 1000 there has been two periods of no power being provided by the Iggy. However as the 1000 carries on working without a blip you only notice as the end of the ride.

Received the unit promptly from order, first reaction..where's the rest of it..it's tiny.
Mounted with a cyo plus lamp in place of Luxos U with SON 28/20. I have only temp assembled with the D1 taped to the front brake cable housing, but having tried that for a few rides I think that's actually quite a choice, so will leave in place. The good news is all devices charge as expected , Garmin 810, Samsung S7 and Anker Astro reserve battery. All still charge when moving briskly with the lamp on. Lamp seemed quite flickery with the Garmin though, and all stopped charging when the speed dropped down when climbing as expected.
This still leaves the same Garmin issue I have with the Luxos U. When externally powered the Garmin charges, but when the USB power supply falls the Garmin recognises this and stops....but it also the turns itself off after 15seconds (unless I respond to the screen prompt not too).. very annoying. I stress this the Garmins power management firmware not the Igaro per se. My approach is to carry on using the USB charger to charge an external reserve battery and then use that to feed the Garmin when needed, bit fiddly but it works - unless anyone has a better answer?
So a good functional little unit, and it frees me from the LuxosU which I think too complicated and that I don't really trust on a wet, windy , Welsh 600. Repeated BCM's have killed all my lighting systems at some point over the years, including variously 2x SON hubs, Schmidt Edelux lamp, B&M lamp, cateye battery lamps, and memorably the mounting bracket for a Hope1 backup light that unscrewed itself on the descent from Snowdon sending the light bouncing across the road at about 40mph.. that too some finding. Let's see what Igaro is like.

Barry

A small powerbank with passthrough will resolve the Garmin issue (i.e Limefuel L60x). Touring cyclists have been berating them for years over this 'feature' and they haven't listened. Eventually the Igaro G1 (D1 accessory) will be released which will give 4 minutes of stop power for smaller USB devices (specifically targeting the 8*0, 1000 etc Garmin units).

Thanks for everyone's comments and feedback. It's good to see and hear about the D1 doing its job. Little tweaks (we have a label printer but the niche demand hasn't warranted its use) will be incorporated. Going forward we will release;

1. power and accessory ports (a service will be on the website to retro fit if you want them) - eta 2 weeks
2. stability bank accessory - eta 2 weeks
3. internal mount bracket (hides D1 up the fork crown with USB cable out the top) - eta 8 weeks
4. solar panel input accessory - eta 8 weeks
4. Igaro G1 - 4-6 month

Thanks again,
Andrew

Hi Andrew,

Any news on ETA for the retrofit service?  On a hilly ride this last weekend, the air was alive with Garmin's beeping as the speed dropped off on the climbs... a buffer to fill in the speed gaps would be a welcome addition to my present D1.  Also, is there a waiting list I can hop on for the d104?

I was using the D1 to keep the Garmin 820 topped up on that same hilly ride as an experiment for longer rides to come, but I wouldn't like to experience the incessant beeping from the Garmin when the speed dropped to below roughly 9 km/h in the future. A 4 minute buffer would suffice for most of my rides.

How big is the buffer battery capacity?  I have a B&M Luxos and on hilly rides sometimes the cache battery discharges fully and my Garmin starts beeping away.  When I put a big buffer between the B&M and Garmin things are much quieter although sometimes the big buffer runs down, like when we were the Peak District and Yorkshire last year.

It was the Shark... not that many non-hilly sections LOL (though I did stick mine on just as we hit the less hilly part, Andrew had his on on the last quarter - so we had a good 100km of beeping :D  :facepalm:

Personally, the less number of times I have to plug and unplug on a ride the better as its a bit of an agricultural approach to getting the connector in to the Garmin whilst on the move.

The hilly sections covered most of the ride! I hear what you say though. The problem would be that it is quite tricky getting the cable inserted into the Garmin, even when stationary. I wouldn't be comfortable inserting the cable whilst riding, and would prefer a solution that doesn't involve repeated removal and re-insertion that would lead to wear of the connection points.

I've just checked the Igaro website, and the stability bank accessory is actually available - I should have checked there first. I think jiberjaber was requesting info on something slightly different?

I don't plug my garmin in while on the move - I find topping it up at controls is more than adequate.

In fact, for a 200, I only ever have to top it up if I forget to turn the backlight off. I did a 275km ride a couple of weeks ago, without topping it up - was running on fumes by the end but it lasted the distance - nearly 15hrs continuous use. I don't even turn it off at controls, just leave it running (avoids the problems you get with elevation reading when stopping and starting the recording mid-ride).

I would use the Igaro to charge a power pack while on the move, then plug the Garmin into the battery at controls.

Having said that, a buffer of some kind would be handy. I looked at the Limefuel power packs but the shipping costs from the US more or less double the price. Anyone know of an alternative readily available in the UK that has pass-through?

The d1acc01 stability bank may give a little breathing room with smaller GPS units at low speed but it doesn't have the capacity to give the duration you'd like.

You will probably find a couple of these at the USB port will give a few minutes charge (with smaller Garmin like units):

https://www.aliexpress.com/item/farad-capacitors-supercapacitors-5-5V-1-5F-c/32596400806.html

Although they'll only charge to 5V most USB devices work down to 4.5V.

RAVPower packs (on Amazon) all seem to be pass-though.   Amongst the smallest/highest rated too.
I've a 6700 mAh unit, cames with slightly padded bag to protect it in luggage. 
I've checked the pass-though works with the Igaro D1, and that it gives quite fast charging to my Moto G.

Most useful information which I believe is supporting my plan of running the D1 during the day to charge power pack while power pack simultaneously feeds Garmin.  Power pack may also be charging phone if required, although tend not to have phone on all the time and only switch on when I need to.  At night Garmin runs off power pack and dynamo used only for light.  Must check to see if my power pack is pass-through and if not then "Hello RAVPower!".

There's also the Zendure A2 (6700 mAh), also on Amazon
(various sizes A1 to A8 available, presumably the number of 18650 inside)

Apologies for putting on this thread, but it's as close as I can figure. And the Igaro is something this suggestion might suit.

Is there a market for a 5W or 6W dyno-hub when one considers the additional accessories one wants to run? Currently everything is at 3W or less because that's what the bulbs added up to in the 1950s. For the committed tourer with backlit GPS, B&M headlights etc, why not sacrifice a bit more to the generator? It's not like it's crippling when compared to what your tyre choice or pressure is.

It would also allow one to run a light the equal of almost any battery. As it is we've reached the 100 lux recently and who knows what Supernova might do next?

Do you need 100 lux? My Edelux II has been more than adequate including fast descents at night. Why need more?

Also, I would have thought enough power option available during the day to charge 'stuff' during the day when not using the light from conventional dynamos.

If the electronics can make sensible use of the higher voltage you can draw more than 3W from a standard '3W' dynamo hub, as long as the wheel is turning fast enough (which is a big 'if' in a touring context).

You can squeeze a little more out at low speed by running a regular dynamo hub in a small sized wheel.  I have this on my tourer by accident of acquiring such a wheel with a second hand bike (I think it was built before small-wheel dynamo hubs with disc brakes were available).

It's an interesting idea though.  Particularly if it could be done in a way that would remain compatible with today's LED lighting...

The hilly sections covered most of the ride! I hear what you say though. The problem would be that it is quite tricky getting the cable inserted into the Garmin, even when stationary. I wouldn't be comfortable inserting the cable whilst riding, and would prefer a solution that doesn't involve repeated removal and re-insertion that would lead to wear of the connection points.
Personally, the less number of times I have to plug and unplug on a ride the better as its a bit of an agricultural approach to getting the connector in to the Garmin whilst on the move.

I don't plug my garmin in while on the move - I find topping it up at controls is more than adequate.

In fact, for a 200, I only ever have to top it up if I forget to turn the backlight off. I did a 275km ride a couple of weeks ago, without topping it up - was running on fumes by the end but it lasted the distance - nearly 15hrs continuous use. I don't even turn it off at controls, just leave it running (avoids the problems you get with elevation reading when stopping and starting the recording mid-ride).

I would use the Igaro to charge a power pack while on the move, then plug the Garmin into the battery at controls.

Having said that, a buffer of some kind would be handy. I looked at the Limefuel power packs but the shipping costs from the US more or less double the price. Anyone know of an alternative readily available in the UK that has pass-through?

Although my experience relates to touring, this is roughly my routine. Having the gps shut down on hills, passing pedestrians/traffic and rides on rough terrain made it too unreliable to have it plugged in at all. My cache battery (Powermonkey Explorer 2) has plenty to do iPad, iPhone and GPs at camp. During the day I top up with a solar panel and/or charge the battery on the Dynamo. Obviously fine to have battery plugged into devices while riding too.

When I grow some and start doing longer Audax, I will top up my gubbins with the battery. Solar panel will just be too intimidating.

Ok, I had a bit of time on my hands recently and was wanting to tidy up the wiring on my D1.  My Garmin 1000 is only a couple of cms away from the Igaro so the wire to the female USB socket and the shortest of micro USB leads is an order of magnitude too long.  In an attempt to tidy this up I chopped off the USB socket approximately half way between socket and capacitor, I then made a new micro USB lead by soldering the internals of a spare micro USB plug to the wires from the Igaro and used some Sugru to make a new casing/insulation for the plug.
So far so good, looks loads neater and the wire is still long enough to reach to anything I'm likely to charge.

While it works fine when up to speed, the problem I've now got is that intermediate speed performance with my Garmin 1000 is problematic; charge is not stable either on or off, it now fluctuates quickly  on/off/on/off.   What have I done? have I unwittingly reduced the capacitance of the system slightly?   I've still got the stock capacitor in the loop, I didn't touch that, but did the socket and extra cable add any extra capacitance that I've now removed??

And yes, I know , I was warned upthread not to remove the USB socket, and to use the micro USB lead as a sacrificial part as micro USB is less reliable than USB A.  I do acknowledge that I've done this entirely at my own risk.  My plan was to just replace my home made micro usb plug every so often or when it needed it.

Following my Thorn audax mk3 rebuild I finally got round to wiring up and using my Igaro as I intended, i.e. to keep my Samsung S7 charged while I am Audaxing.  I use my S7 to record the ride using Strava and to take photos during the ride, with the occasional phone call , text message and Internet access whilst at controls.  I have Igaro wired in parrallel with my B&M Cyo Premium (80 Lux) into my Shimano dyno hub.   Last weekend I did the 'Dorset Double'; The Hardboiled 300 on the Saturday and the Dorset Coast 200 on the Sunday; it was the ideal weekend to test out my proposed LEL bike setup which included the charging capability of the Igaro.   I can report that both worked very well!  For my bike setup I have decided upon a Carradice super C barbag and a Super C Audax saddle bag.  The barbag arrangement means that I can keep my phone in the bag with the charging cable, connected to my phone,  running out of the lid into the female plug on the end of the Igaro cabling.   To maximise the charging efficiency I kept my phone on flight mode (Strava just needs the locatyion / gps option enabled) and closed all other apps.  I also kept my Cyo turned off.  Although I have no definitive figures the phone charged at a good rate despite Strava running and me taking lots of photos!  On both days the charged reached 100% after a few hours.  I did also notice that I can't climb a 20% hill fast enough to keep the charging going as indicated by the 'bleep' my phone makes as charging stops and begins!

Running the Cyo and charging the phone is not really an option.  When trying to do this I noticed the light output was significantly dimmed, with occasional brighter flashes; the phone does charge during this (tested using the Android AMP app,  but the lighting is more important; therefore I simply disconencted the charger cable to give me full lighting.  The discharge with only Strava and GPS running seemed pretty minimal on my S7.

I do have a couple of suggestion with respect to the build:

1. The female plug came apart during the 300K ride but I managed to gaffa tape it back together.  Perhaps the female plug needs to be more robust

2. The wires on the end of the cable to connect to the Dynamo are extremely fine.  I would like it to be a bit more substantial and make it esier to strip
 without losing wire.

3. provide a slightly longer wire/cable to enable more routing and fixing options on both sides of the device.


these are only minor points and after a full weekends testing it a big  :thumbsup:  from me!

I think you are seeing the same behaviour Andrew and myself pointed to a week ago, I haven't chopped or rewired my USB, but I seem to recall before the recent V4 garmin updates, the Edge 1000 would just beep once and say, external power lost. and then at an appropriate time & speed would beep again and say, external power back on.  Behaviour now appears to be beep beep beep beep.... as it flicks between power there, power not there. 

So for me, this is either someway has changed on the Garmin about how they deal with the power being present or, something has failed on the D1 (capacitor?)

I'm erring on the Garmin induced version as it seemed to work OK before, and I noticed Andrew's Garmin doing the chirpy chirpy song when we slowed down on The Shark's hills so.  With the Luxus U, this is managed by there being a small battery in the lamp which fills in for a short period of time the power dropping from speed reduction.   Present work around suggested is to use a power bank, preferably one with pass-through charging.

igarocom have stated they are looking at a potential solution using large capacitors to provide a reservoir like option to fill in the gaps...

Also, that is a very good point.  I'd been off the bike for a few weeks and during that time 2 things have changed,  1) me chopping the USB socket off and 2) updated garmin firmware. 
I'd assumed that is was 1 that caused the issue but sounds like it may well be 2 if others are getting this without hacking their igaro. 
If so, that's a relief at least as far as my molishing skills are concerned.

They are shorted at the USB end of the D1. If the cable going from that to your unit has the data cut it would undo it.

Post by: igarocom on April 11, 2017, 07:01:42 pm
It sounds like Garmin are changing the firmware to poll more frequently, which is a problem at lesser speed as the dynamo AC frequency is so low. This condition was the reason for introduction of the stability bank accessory as a few phones and power banks do the same. Likely adding it will help at very low speed (other users have confirmed it makes no difference when speed increases).

The capacitor fitted to d101-103 models is overrated and the highest quality available (Nichilon Japanese, 10X working life), but it's capacity is limited and is in some cases not enough to smooth the low transients. Unfortunately size has a trade off.

Super capacitor accessory for the output side is under way, but 375mA (typical Garmin current) over a few minutes is a tall order even for the capacity we're thinking off (super capacitors are current limited which may put an end to the idea). Hopefully if 30 seconds is achievable that will be enough.

A few have asked by PM to help out, it may work better if we pay the postage to borrow a unit and return it with an accessory once we've worked out the appropriate size of the super capacitors required.

I'll stick an update on here once they arrive.

Edit: the math says 90 seconds of run time for a Garmin 810 for the super capacitor capacity we've ordered (that's at zero velocity).

Latest update:  I’ve re wired my micro USB plug to short the data pins and it doesn’t seem to have made any difference – my Garmin 1000 still plays the fluctuating charge ‘chirpy song’ unless I’m either stationary or riding fast.
I’ve tried to cure this by putting a buffer battery with pass through between the Igaro and the Garmin.  The battery I’ve used is the Zendure A1.  Still no good though, the Garmin still chirps until I get to speeds of 30kph+  .  The only difference now is that I get charge from the buffer while stationary.   
The igaro/Zendure buffer combo charges other stuff fine at all speeds e.g. phone (sony xperia Z3 compact) and my spare front light (cateye volt 300), it’s just the Garmin it struggles with.  What’s going on???  surely the buffer would smooth the charge delivered to the Garmin?

Edit: the math says 90 seconds of run time for a Garmin 810 for the super capacitor capacity we've ordered (that's at zero velocity).

If my understanding is correct, the super capacitor would kick in when the speed drops below the charging speed (which for me is circa 9.5kph), keeping the charging going for at least 90 seconds, but probably longer as there may still be some charging from the dynamo at the lower speed. By my quick calculations that would provide silence for 150 - 250 metres of climbing, which is probably good enough. Most longer climbs that I am likely to be doing would not be steep enough to reduce my speed to below the charging point, and I could survive the occasional climb with the bleeping ... it's just annoying when it occurs with every climb on a hilly ride.

Still no good though, the Garmin still chirps until I get to speeds of 30kph+  . 

I'm using a Garmin 820, which starts charging again as soon as I get back up to 9.5kph. Could it be the buffer battery that you are using that means that the battery takes the charge at the lower speeds, and only passes the charge through to the Garmin at the much higher speed, at least until the battery is charged again?

The Z3 is one of the most difficult of devices to charge (needs the d1acc01 stability bank, or power bank). With either of those your Garmin should be fine, I wonder if the port on the Garmin is damaged?

Strange indeed. Probably best to eliminate the D1 at this point by sending it in for testing (and replacement if necessary). I can't explain why the other devices are charging though. Do they actually charge in terms of a % indicator or just a power LED which could be giving a false indcation? Clutching at straws but perhaps the D1 regulator is only giving residual current. It would be the first time it's occurred if so, but with electronics anything is possible!

If it performs to spec this end we can add an accessory port and try with a d1acc01 stability bank and see if that helps? I'll PM you.

Odd experience with the IQ-X on the audax yesterday but I'm posting it in this thread because I suspect it might be Igaro related...

It was the first proper night riding I've done since fitting both the Igaro and the Secula rear light.

On the outward leg, the IQ-X behaved normally. Bright as you like. Secula also impressively bright.

On the way home, the IQ-X seemed a lot less bright. Secula was still very bright. I would say the IQ-X's brightness level was similar to my ride last week when I had forgotten to disconnect my phone from the Igaro. On that occasion it returned to normal brightness when I disconnected the phone. (That was before I'd fitted the Secula.)

On this occasion, there was no phone connected, although I'd left the phone charging cable plugged into the Igaro from earlier. Thinking that maybe having the cable attached was still causing the Igaro to draw power, even with the phone disconnected, I removed the cable. No difference.

Eventually, I tried disconnecting the Secula as well. It made a little difference but not much.

Is it possible the Igaro was for some reason still stealing power from the light even with nothing connected? And if so, is there any way to stop it?

Or could it be the Secula's fault somehow?

I'd also been using the Igaro to top up the Edge 510 (wouldn't normally charge on the move but in this occasion I'd left the Anker at home) and found it kept going into auto shutdown mode - as in every 30 seconds, regardless of speed. But then it would revert to normal operation just a few seconds later. Most odd. But given Peejay's experience with his 820, I suspect this is a Garmin issue rather than an Igaro one. It still charged up, but maybe not as quickly as I'd have expected.

Hi Citoyen,

Another user was having similar problems a few pages back, I recommended he lightly oil the inside of the USB plug (WD40/GT85) and haven't heard anything since. I'd do this first as it's the #1 culprit.

For your other question, the D1 consumes almost zero power when no USB device is attached. It will consume power if the over-voltage kicks in but that's not going to happen with a light on. The only situation would be if it's developed a fault, but as of yet there's been no D1 suffering electrical degradation. Peejay's may be the first, if it is the case. Others have failed where the wires have been ripped out by installing too tightly. As always, you're more than welcome to send it in for an inspection.

Ah! Thanks, I'll try that.

Is this a moisture thing? Makes sense if it is, as we did have a spell of rain during the ride - I keep the usb socket tucked inside a top tube bag but I guess some moisture could still get in.

I'll try to get out on the bike this evening to test it again.

Is it possible that certain types of USB cable plugged into the Igaro could cause it to draw power, even with no device on the other end?

Regrettably the super capacitor idea hasn't worked, at least not with the Chinese super capacitors which are of poor quality. The named manufacturer brands are very expensive for the charge capacity required which would make them non cost effective. It's back to a powerbank with passthrough for now.

Although Garmin have been told many a time about the troublesome power alert "feature" they've yet to listen. It may be worth starting an internet based "sign if you agree" campaign to put it on their radar.

Re: citoyen, USB

It's explained here (USB section) https://www.igaro.com/d1/installation

The USB pins quickly corrode when they get wet (regardless of gold plating which we also use).

No open ended USB plug will make the Igaro drain power.

Can anyone recommend JUST a power converter? I assume for £80-£90, this has some sort of cache battery. I already have a brilliant battery (Powermonkey Explorer 2) In other words I don't want to pay for another battery or cache device. Just the wiring and the converter.

I would piggyback a cable off my Schmidt Dynamo hub/headlight wire up to the converter which I would then plug in various USB charged items like my iPhone, GPS and battery pack. Is there something from Igaro like this perhaps?

PeeJay's D1 was returned and confirmed to be working fine. We've fitted a stability bank and it's on the way back to him. It looks like Garmin has indeed updated their firmware and the stability bank will be necessary post firmware upgrade. Once confirmed we'll write to model d101/2/3 owners to let them know.

Thank you. I'll take a look. I use a Garmin and have had all the above 'powering off' messages experienced upthread using B&M's USB/headlight system. I'm now running a Schmidt hub and Edulux 2 so I may hang tight until Igaro has an option that solves the slow speed/no power issue.

It's really great to see a product representative using the experience of the 'real end users' to develop the tech. It's bound to turn out for the best.

I'd suspect the light rather than the hub.
A hub just has wires and magnets, and if a wire breaks you'd get no light rather than dim light.
A light on the other hand has a variety of electronic components, which can lead to interesting failure modes. I had one that failed (at 70 kph), with the result that if you went faster than about 15 kph, it went out, and then wouldn't come back on (at about 1/4 brightness) until after you'd come to a complete stop.

I'd suspect the light rather than the hub.

I was thinking about how as well as the low front light, the Garmin was going into shutdown mode when connected to the hub via the Igaro even at high speed, which leads me to suspect the hub isn't putting out as much power as it should. (I'm not using both at the same time.)

First step will be to  get a multimeter to test the hub's output.

Then try all different configurations of the lighting/power setup.

Whatever the cause, it's something that changed about the setup between the start and finish of the Oasts & Coasts 300 last weekend.

In any case, to get back on topic, it seems unlikely it's the Igaro's fault.

HeltorChasca -> no cache battery in the D1. Check the website, it's been updated recently and has more info on it.

Thank you. I'll take a look. I use a Garmin and have had all the above 'powering off' messages experienced upthread using B&M's USB/headlight system. I'm now running a Schmidt hub and Edulux 2 so I may hang tight until Igaro has an option that solves the slow speed/no power issue.

It's really great to see a product representative using the experience of the 'real end users' to develop the tech. It's bound to turn out for the best.

Most users here are using the d101/2, the d103 came with an accessory port for a stability bank (optional) and d104 onwards includes it (mandatory). With the stability bank there is no on/off cycling at low speed (this may not apply with a light on since it will take much of the power away from the D1). If the speed is too low power will be lost. A powerbank with passthrough will resolve this.

After an initial local test last week, I finally used my D1 in anger on LWL at the weekend, mainly to charge a powerbank in order to top up my Garmin 500 (you can't use these old models to record rides whilst cycling) at the controls. A dodgy connection between my lead and the powerbank let me down. The D1 worked brilliantly off my SP dynamo.

Really liking my igaro.  Go out for a ride with front light automatically lit and the Garmin has more charge when I get home than when I started.

I did have a limefuel pass through pack which stopped charging.  I am about to try a new Ravpower pack and hope to do a night ride this weekend.

Apologies for delay, I can now confirm there is no problem charging any Garmin unit with the firmware update when using a D1 with the stability bank.

For d101/2 users (the model without an accessory port) there is a service to have the new stability bank capacitor retrofitted inline. Just buy the stability bank (about £8 exc return postage), send your unit in and we'll send it back fitted.

Have you considered connecting the USB port using the same round connector as you are using for the stability bank and solar input lead?

It would eliminate the need to return to base in the event of port failure, and would also allow the use of the B+M round plug to mini- or round plug to micro-USB leads, allowing weatherproof connection if the item being charged was in the handlebar bag

Post by: igarocom on June 02, 2017, 07:50:00 pm
We have (1.35mm connector, can't use the same) but it's not a priority. The Model 5 has two USB plugs and chances of both failing is very small. Also, you can use a 30cm USB extension cable, tape the join up and then the extension cable becomes sacrificial. We were trying to source the manufacturer of an IP67 rated USB design but haven't had much luck. Still trying, but we might end up opening a mould and recreate it ourselves.

At the moment our focus is on the G1 to give Garmin users 4 minutes of standby power.

Related enquiry, recently came into focus (when my Garmin "out-front" mount broke).
Can anyone recommend an "out-front" mount that has sufficient room to insert the charging cable whilst mounted ?

Thoughtlessly, bought an actual Garmin replacement, to discover shock/horror, there's no room for the charging lead (via Igaro D1) to insert without fouling the bar.

All thoughts recommendations thoroughly welcome !

That's what I use, a right angle, mini-USB lead, easily obtainable from eBay. The USB socket on the Garmin Edge 810 (mine) is "upside down" so you need the oppposite right angle to point the cable away from the mount.

Hello,

Im after advice from those who have fitted an Igaro alongside a headlight to an SP/Shimano hub.

Is it just a case of twisting the wires together into the connector plug or is there a better way?

Cheers.

Twisting the wires is what I did on HK's Condor but the Igaro wires are a bit fragile. When I get some time, I'll probably try the soldering and heatshrink route.

I bought one after reading this thread (just too late to get the discount) and it's been sat in its box ever since. However, with LEL coming up, I've fitted it to the fixie and I plan to use it to keep my Tecknet 15000mAh battery topped up. I took a couple of these with me on PBP to keep my phone charged (and letting it record the ride and display speed, HR data set on my Wahoo RFLKT+ head unit). I've done some basic tests so far, in that:

 - spinning the front wheel by hand is sufficient to wake up the Tecknet
 - if I spin faster, the charge indicator light starts to flash indicating it's actively charging
 - slowing down and it stops again, but charging resumes successfully

As I have a SON Deluxe, it will not charge as rapidly as with a SON 28, but should get some decent charge on descents.  I will start with the power bank fully charged. The bank should be able to charge the phone several times over. I'll run a cable along the frame, wrap up the Igaro's USB port, and keep the cache battery in my saddle bag. I believe the Tecknet can act as a pass through charger but once the phone is fully charged it will turn off the output. The phone can record a 200k ride on a full charge, the Tecknet probably charges the phone several times, so using the Igaro to top up will hopefully make it last the whole ride with one battery.


Title: Re: Igaro D1 USB Dynamo Power Converter
Post by: thing1 on October 26, 2017, 02:48:18 am
How did that go Simon?
I also bought an igaro some time ago (no accessory ports, single USB outlet, plus one small capacitor heatshrunk to it version) and only really used it in anger for the first time today.
Plan was to just charge my Ravpower 20,100 mAh battery pack through the day and then charge gadgets from that at night. We rode for 4hours but at the end of riding my USB doctor said it had only supplied 120mAh. Basically nothing. The Ravpower has an intelligent load circuit so will try and draw 1.1A (empirically determined) but with the igaro I see it back off to about 0.28A load. Coupled with the supply cutting in and out (as our speed fluctuates) I expect it's spending more time detecting what load to place than actually charging.

Anyway long story short, what's people's recommendations for a great battery pack to charge from it? Unfortunately we're in California and heading on holibobs in Colombia in 2 weeks so no time to return the D1 for any of the glorious upgrades invented since I bought mine.......

I charge my phone directly off the Igaro but if I were to use a powerbank, which would be for off road, then I'd use my Xiaomi 20,000mah powerbank which has pass-through charging. The powerbank starts charging as soon as power is supplied and turns off automatically when the charge ceases. You can basically leave it in a bag and the powerbank manages itself. This is good for things like long drags up steep hills where you aren't generating enough speed to provide adequate power, but ensuring that the powerbank isn't draining itself of power by remaining on.

Thanks for the pointer! With a bit more testing I discovered my Igaro had stopped charging altogether. It now appears to behave like an expensive 0.5 ohm resistor. I guess the input lead has a short -- I'll work on returning it when back in the UK.
I also worked through my inventory of battery packs to see how they cope with variable input voltage.  Quite enlightening - several back of current as the voltage drops (by design, or using cheap linear regulator?), some actually increase current (switch mode regulator?) and the most advanced have a stateful algorithm that slowly ramps up the current but then rapidly backs it off whenever the input voltage drops. The Anker Astro SE was almost the winner in this - except if the input drops to 4.4V it powers off and needs a button press to resume charging which would be a pain. That said for this trip I'm going to be using the LUXUS-U for power and that doesn't seem to sag voltage much at all when loaded. It's either at 4.9V (less whatever resistance the charging cable drops) or nothing if overloaded.

Sorry to here that thing1.

The issue involves the PCB - over time it has a slight expansion and if the case is too tight it's enough to bypass the insulation layer it fits on which then results in a short at the input side. The problem lies not with the PCB per say but the custom titanium casing which during manufacture has proved impossible to get equal tolerance. Some of these cases have a -.2mm variance and it's enough to disallow the expansion.

We attempted a correction with Model 4 by increasing the insulation layer thickness (originally it looked like this was breaking down) but it didn't resolve the issue. Model 5 corrected it fully by shaving the PCB's - no failures since it's introduction in April.

Where it occurs the warranty will ensure a swap-out. We haven't had any returns for a while now so most Model 1 -3 units that had that issue have since been replaced, while the majority have a 0 or + casing variance and won't have the issue at all. We publish the stats on our website.

(https://www.igaro.com/misc/d1_failure_rate.png)

Ah interesting. We were riding in the middle of a late Californian heatwave - it hit over 100F (36C) in Santa Cruz where we were.

We attempted to gain output graphs from the manufacturer a year ago but the engineer was away at the time. As I recall reading the output is significantly different and this could overload the D1 electronics. SON says...

"Schmidt Edelux and Edelux II headlights are made to be powered by a 6 volt, 3 watt hub dynamo. The use of Edelux or Edelux II powered by Velogical dynamos or other experimental generators risks damage to the headlight's electronics. Damage caused by overload through such generators is not covered by the 5 year Schmidt guarantee!"

HK has been holding off on getting a second Igaro (after the one received through this thread) for a while now, despite being wildly enthusiastic about it. The new Igaro will be going on her commuting/ do everything bike with the original D1 probably ending up somewhere else in her fleet for next year's PBP. No doubt she'll find an excuse to get a third Igaro somewhere down the line.

I understand that the too-fragile cables got beefed up a while ago and that several upgrades and options (a little complex for this bear of little brain) have also appeared. Is it possible to get the stronger cables retrofitted to the original D1 for a fee?

Apparently the D1 is being replaced by a D2 but I have no idea what is actually going on. Facebook will continue to be off-limits for me and there seems to be very little Igaro info elsewhere on the interwebs. Can somebody provide a Reader's Digest version of the situation?

A quick skim says the D2 ETA some time in 2019. It has a USB C socket built-in and the smoothing capacitor has been incorporated inside the casing. It seems like it has a moderately smarter / more efficient voltage convertor inside.

There's also something called a C1 which seems to be handlebar mounted and have status lights, and also has a vague future ETA (no recent posts about it).

There's also something called a C1 which seems to be handlebar mounted and have status lights, and also has a vague future ETA (no recent posts about it).

I found this post from April 2018 on Facebook about the C1:

 In other news the Igaro C1 is onto it's forth and likely final PCB and we can share a picture of it with you now. This one has been designed with casing form-factor in mind, and it is to fit on a 31.8mm handlebar next to the stem. It's only 40mm wide.

Look closely at the attached picture and you'll be able to spot two button switches and four LED's. These will give status indication and control over lights and USB.

We mentioned in a previous post we've hit a 99%+ efficiency rating (maximum), but now we can confirm the Igaro C1 also features ten stage load matching circuitry configurable to a particular dynamo model. This allows a peak power extraction of around 10W from a SON28.

The Igaro C1 will feature 50 farads super-capacitor storage. To put that into perspective, a Supernova E3 Pro 2 has 2 farads. This extra capacity can keep your devices charging while you wait for traffic lights to change and provide more power to bicycle lights (Igaro C1 will support the Igaro F1 and Igaro R1).

Another never done before feature, the Igaro C1 supports USB Host Mode to communicate and identify devices to allow for charging profiles. More charge, less light output, trickle charge below a specific speed, you decide. Once the profile is engaged the Igaro C1 switches to USB Power Adapter Mode (as required by Garmin units and similar). Profiles are managed over Bluetooth 4.2 BLE (as is updating the Igaro C1 firmware).

We're aiming for a release later on in the year but the complexity and amount of programming may push this back. Fingers crossed!

My preordered D2 turned up on Saturday (7th). SON piggyback connectors now connected, and waiting for proper testing.

Comment so far...
a) the cable pins look a bit vulnerable if you carry the D2 in with your general luggage when not in use. Suitable box required if I'm not to leave it on the bike full time. [edit] This was suitable (http://www.lloydspharmacy.com/en/noise-x-foam-bullet-shape-ear-plugs-2-pairs) - free earplugs included
b) the heat shrink supplied for the SON piggyback connectors doesn't shrink enough to grip the cable. I expect I'll squirt a bit of hot melt glue in.
c) I got 4 of the D1 foam frame blocks (https://www.igaro.com/d1/d1mnt01). Not quite sure why.

Because as a commercial entity they will have to pay for disposal of unsold products? If they send 4 blocks to each D2 customer the can reduce (or remove) there stock and thus save on disposal costs.

It does look neat. USB-C connector is an interesting innovation. I think I'll order one when stock is available.

Seems ok so far, will attach to bike, shame there wasn't an option to have a plugged power option as in the D1 so rather unplumb all the existing wiring for my D1 I've knocked up a plugged lead sacrifice of a capacitor unit I had unused f I'm my D1.

I've got some USB C leads arriving tomorrow, a C-A socket and a C-Micro B lead suspect I'll stick with the C-A as I can then easily replace the end cable if it breaks.

No idea where I'll mount it, suspect I'll silicon the usb port and hang from the aerobars with a couple of cable ties when I'm happy with it.(https://uploads.tapatalk-cdn.com/20190909/1a0feca3565ddb54c9c383b5af99de71.jpg)

Hmmm that didn't last long...   anyone else using theirs yet, can you confirm if there is supposed to be an LED on or not when it is working, mine worked and now doesnt work.  Cables all 'bell out ok' so pretty sure it's the D2.  Glad I didn't take the D1 off the bike whilst I was trying this!

Working - steady LED
Working, no or small USB power consumption - steady with off-blip
Initialise/warm up - flashing
Disabled due to dynamo lights - brief flash, then unlit

The manual also says

When the bicycle begins to move the Igaro D2 assesses whether dynamo lights are connected. For this reason it is important to only turn your dynamo lights on when at a stop as doing otherwise could result in dim dynamo lights
Could be irritating with a sensomatic light, having to stop to get proper lights at dusk, or when entering a tunnel.

The newer B&M lights just use the sensor to switch between daytime visibility and illumination mode.  I think they're following some DRL regulation or guideline or something?  I preferred the old senso behaviour.

Ta - I've been in touch with Andrew and I'm shipping my D2 back to him to investigate.

Hi All,

We had a few issues with the pre-release units (jiberjaber got caught with one of them) and they've now all been replaced.

As production has stabilised we can offer a 12% discount for anyone willing to write a review here on yacf. As before, write anything you want  :thumbsup:. The code is YACF201910 and can be used on our website for at least a month from now. Apologies we can't offer a larger discount but the electronics in the D2 are far more costly than the D1 and ultimately limits it.

Someone asked about the power pins. This was a trade-off, as there's NO room at all (to put it into perspective the D2 has the most condensed circuitry of any product of this genre including two stacked PCB's and three types of capacitors in the tiny casing). The only option was a wire coming out or the two pins. With the D1 we found users would accidentally forget to leave cable flex for handlebar rotation and rip the wires out so the pins avoid that. Although they're small we've used the best quality ones we could find, purchased here in the UK.

The production units (not pre-release which have all been replaced) reverses the decision to switch off with lights. Success will vary (speed, light wattage etc) but the unit will attempt to power share.

Also waiting on my D2 MII after it turned to ice cream in my top tube bag. Hope springs eternal and all is well with this next one.

Very interested in replacing my D1 with this unit especially now the no power while lights are on has been removed (i use power on at night to dip my bright light briefly for traffic)

igarocom: I am concerned about the USB-C connectors, I was following the development of your products on Facebook closely and at one point you publicly stated that you had modified some circuit boards as you found that USB-C tracks over with moisture far too easily. As you have made this unit very small I feel you have now used this more vulnerable connector regardless due to size constraints.
I understand the D2 does not require any air flow for cooling so i guess these are designed/recommended for internal storage now.

There's no such thing as a waterproof USB port. The smaller and closer the positive & ground track the greater electrolysis will occur when a bridging liquid (i.e water) is present. For this reason, as you say, USB-C is more likely to corrode when powered and wet. The simple answer, which applies for all USB ports, is not to get them wet when they are supplying power. This is why stem cap solutions don't work in the real world. USB-C was chosen for it's size, although the pins are more reliable than USB-A in terms of insertion count.

The D2 produces no heat so placing inside a bag is fine.

Really liking the look of the D2 (and would probably buy one if I didn't have a perfectly functional e-Werk), though I'm not sure about the power pins:

Given that it's going inside luggage because the USB port isn't waterproof, why optimise the form-factor and power input for handlebar-mounting?  Seems like the power pins are going to be vulnerable if it's rattling around in a bag, potentially with the cable disconnected, and a slightly larger case with a female power connector would be better.  (Or alternatively, given that it's going on the handlebars, why use a USB connector rather than some more 0.1" headers for the output?)

I'm not sure how I'd optimise this, other than with two different products.  Fair point about captive cables getting damaged; I don't like them either.

It is a fair comment, true and valid, but design has to have a commercial aspect. A popular design chosen by several of our competitors is the top cap design and some of these competitors are touting the design as waterproof. This is plainly ridiculous as with a USB inserted not only will water enter when power is on but it will sit in the connector and electrolysis between the pins will occur. However it looks small, neat and unobtrusive - so increases commercial success. More sales, a one year warranty and a higher initial cost mitigates failures. We're giving a 5 year warranty which is 3 years more than the next competitor - just look after the pins and USB port. (if you feel you can't, take out insurance!).
