Hi, I also just got myself a nice 900 mAh pass-through battery, so this thread was exactly what I was looking for.
But I have a few additional questions:
Firstly a "duh!, of course!", but I want to make sure:
I can charge my pass through 900mAh on my threaded charger, just like a charge my other batteries (650mAh, 280mAh, 180mAh), right?
But then something more technical:
I happen to have a cellphone (Moto Defy) that also charges through an USB cable. So I've been wondering whether I could use my moto mains-adapter:
1. With my USB pass-through cable (almost identical to my phone cable, just mini-USB instead of micro-USB)
2. With my threaded charger
The output specs of the wall plugs are a little bit different:
phone: 5.1 Volts, 850 mA
e-cig: 5 Volts, 500 mA
(the very short threaded charger: 5Volts, 420 mA)
Might the 900mAh pass-through battery get cranky when offered more current?
(If it was only a pass-through without a battery I'm guessing it would just vape a little hotter - or maybe a lot hotter?)
I'm guessing the minor difference between 5 V and 5.1 V wouldn't matter much, but could the batteries take the higher current? Could the threaded charger? (And does it actually modulate the 500mA of the plug down to 420mA, or is it just that it itself has whatever resistance is needed to make up the difference?
(Sorry, it's been 25 years since I learnt this in school, I only remember enough to be able to follow the reasoning, not enough to whip the formulas out of my memory and calculate it - except for plain V times A equals watt (mind your units!), I've totally forgot how the formula(s) with resistance work )
Help? I'm trying to read through what wikipedia says about USB-charging standards, but so far I'm not sure I'll even understand it (or have enough data about the batteries to be able to make use of it - all my batteries are plain and not branded, the 900mAh passthrough is from LibertyFlights).
