Igaro D2
« on: October 11, 2019, 10:37:01 am »
My Igaro D2 arrived this morning and I've just been taking a look – impressively compact, though those exposed power prongs are a concern... Time will tell, I guess.

This is my first USB C device and the connection doesn't seem very secure – the plug doesn't fully insert and, when connected, the plug wobbles from side to side quite a bit. The plug also pulls free with very little force. This is in marked contrast to, say, Lightning, which feels considerably more secure.

So is this just a 'feature' of USB C and/or are all D2s like this – or has this one missed the QC mark..?

USB C should have a nice positive click when it’s fully in, just like lightning.

Maybe check the socket for debris?

The socket and plug both appear to be clear. Definitely no positive click.

Update: Possible resin in the USB port, according to Igaro, so sending back for a warranty swap. Ho hum.

thats annoying, but at least you aren’t being dismissed as an inconvenience to the manufactures.

On my second D2. The first had issues with the epoxy which leaked out into my top tube bag and heated up. Stopped charging and my headlight flickered regardless. I ended up taking it apart, mid-ride so I could see where I was going without having a seizure.

I now have the replacement which has an opaque epoxy which I assume is now the correct epoxy. Igaro have also changed the software so you can charge devices while running the light. Today will be my first ride testing it out. Seems fine on the work stand but only time will tell.

I REALLY don’t like the look of those little prongs. I’ll put a fiver on those not being up to the job.

I was disappointed that Igaro didn’t apologise about my top tube bag or offer any compensation when I paid full price and clearly the first device caused damage and wasn’t fit for purpose. Not great marketing or customer service in my opinion especially as they would be best off getting solid feedback on social media.

My confidence is really knocked back. It is an expensive purchase for someone on a low income and I really hope this second offering is up to the job.

Just got back from a 100+km ride to try out the D2.

I think I either misunderstood the email from Igaro or it’s too ambiguous for the likes of me. I understood from it (or misconstrued) that the device, with its new software, will charge even with the headlights on. This is NOT the case. It doesn’t charge when running lights. Or at least mine doesn’t. At least it charges when they are off.

I will need to do a ride in true darkness to see if the headlight (Son Edelux II on a Son hub) runs at full brightness when the Igaro D2 is attached.

Thanks for the picture JulesP, that's definitely resin in the USB port and we should have caught it before it made it out. We check all of them now but clearly missed one.

HeltorChasca, the SON Edelux 2 is a high power light and leaves nothing for USB charging. It leaves so little the D2 can't even initialise. If you blip the light on/off the D2 will initalise but even then there simply isn't the wattage from the dynamo to do both with this light. Please email us regarding your epoxy damage as we've been overloaded with the swap-out task and have missed it - we also pay warranty return postage (no messing about from Igaro on warranty or customer service).

Update:

AFAIUI Second D2 has been recalled and I’m awaiting the next offering.

3rd time lucky I hope.

There isn't a current recall.

To clarify the email that was sent, we had a D2 Pro unit (which has three tuning networks) fail when used with a particular light (Supernova E3 Triple). We've not been able to replicate the issue and haven't had any further failures so it may have just been within acceptable tolerance for electrical failures. It was replaced and hasn't failed again. Another user has the same set-up and we're awaiting to here back but it is the slow season for touring which doesn't help. We've pro-actively redesigned the third tuning circuit so if it is proving an issue we can expedite manufacturing and replacements, however unless another failure occurs it'll be shelved. D2 Lite and Standard models don't have the third tuning circuit so can't have the potential problem.

Is charging with D2 and tail light expected to work with B&M lights? In this case likely using IQ-X as light, but maybe others too.

Available power = speed, wheel size, dynamo type, unit efficiency, unit tuning.
Power demand = lights + USB device
Success = available power - power demand.

I'm mostly thinking the greedines. For example Beacon has two options, frontlight or charging priority. According to manual it seems that Igaro has frontlight priority, if it is switched on. Meanwhile B&M doesn't have option for taillight only. :)

You can't really have a priority mode without applying a blanket restriction on the current to the USB device. Some USB devices are happy at 100mA, others will drop after 500mA, others expect 800mA in USB 1.2 power adapter mode.

The only way to really do it is through USB enumeration and applying a profile based on which device is detected. You'll find that level of prowess in our upcoming Igaro C1.

I got one of these recentky and road tested it today. 

A partial success.

- Succesful power to the D2 when the wheel was rotating (evidenced by solid red light)
- Ability to divert power to the hub light (evidenced by er, light coming on)

My ultimate aim however was thwarted.  I was trying to use the Igaro to power an Etrex 30 so connected the USB on the igaro to the GPS by cable.  The GPS had no batteries fitted. 

Initially on a few rotations of the wheel the GPS powered up.  All good I thought but after a while the GPS would switch off even when the red light on the igaro untit was showing red & the hub light was switched off.  I persisted with it a few times but it just kept happening....probably the longest the Etrex30 was on was maybe 5-10 mins. 

Im not the most technically minded or patient person so the most likely answer appears to me to be either (a) Im doing something wrong, I just cant fathom what or (b) the power demand of the Etrex30 is more than the igaro unit can supply. 

All assistance appreciated.

The problem is that the GPS needs a constant supply and the dynamo provides a wildly varying amount - sometimes too high, sometimes too low. To smooth out the two you need energy storage, and there’s only a small amount inside the Igaro.

The obvious solution is to put a battery in the GPS.

Thanks Grams.  in this scenario then will the GPS draw power automatically from the Igaro when its able and fall back on the batteries otherwise? 

If so the net effect should be extended battery life. 

I was perhaps rather naively thinking i could rid myself of batteries for good, but at least if i can extend their lifespan its a +

Yes, it will.  For 30 seconds or so (with a helpful warning about external power being lost).  Then it will switch itself off.  Which is still an improvement, as it shouldn't lead to file corruption the way sudden complete loss of power can, but makes it unusable in practice.

(The HCx series used to have a configurable option to disable this warning and auto power-off, but they removed it in the 10/20/30)

If you really want to use it this way, you'll need some sort of battery pack inline to act as a buffer.  Or - alternatively - have an AA charger connected to the igaro and a second set of batteries, and swap them round when necessary (this has the advantage of not exposing the eTrex's mini-USB socket to vibration and weather).

For completeness: eTrexes can't actually charge the batteries with the USB power.  So you're just preventing them from running down.
Careful, Kim. Your sarcasm's showing...

If the light on the D2 is constant it's giving out power, but it may have became too low at a decreasing speed and triggered the USB devices UVLO (under voltage lockout) before the D2 triggered it's own UVLO. This doesn't happen often but would explain why the D2's red light is on constant and no charging is occurring. To try and work around this the D2 will reset power completely when you pick up speed (auto reconnect) but it's not 100% perfect because there's the delay for speed to pickup (assuming it does) and by that time the Garmin may have shut off.

If the D2 has a steady flashing light that means there's no power out, the D2's UVLO has triggered. Power will re-enable when speed increases about +7kph over the point of turn-off.

Most USB devices are fine charging directly but there are outliers which are problematic and several Garmin units fall into this category. There's a list of powerbanks at the bottom of this page which may prove useful. https://www.igaro.com/usbcompatibility

Many thanks.  Im going to try an inline battery.  Thats once Ive taken delivery of the necessary cables.

Is there any notable difference between Pro and standard 2 devices? I couldn't find information about the old devices anymore.
