Ok, I have decided to ditch the tablet and kindle.
On Saturday I got a new phone
It is awesome. As I mentioned previously, last time I did everything I needed on my phone - photos, blogging, googling stuff and posting pictures of my lunch
I only thought about taking my tablet to make life a bit easier, but to be honest, I don't think it will make any difference other than take up valuable pannier space.... The new phone has excellent battery life - of course, it's brand new, but all the reviews I read said it had really good battery life and I've been hammering it and so far battery life does indeed seem good.
I've also installed the Kindle app and have been using that to read for the past few nights and it's absolutely fine - so the Kindle goes.
So.... I have dug out an old 13Ah Anker to do some testing. I'm pretty sure it's a bit knackered - it is a few years old and has been sitting in a draw for over a year doing nothing, so I will still be going for a new battery or two.
One thing I've noticed is that when I charge the phone from the mains it says "Super charging" and it charges in a err... super kind of way. When I plug it into the Anker, it doesn't say "Super charging" so I guess it's just charging normally.
Can I assume that I'd need a battery that supports some sort of quick charging if I want it to be all super and stuff?
Edit: My phone is a Huawei Mate 10 Pro and apparantly it doesn't use Quick Charge, rather their own fast charging tech... hmmm..
Edit 2: Just found
this which pretty much tells me everything I need to know....
Edit 3: So basically, my best bet to get "Super charging" is to get a battery with USB-C to USB-C charging so I get an output of 5V/3.0A.
