Blasphemy!
Anyways...
I received the Power Bank today, well I actually received it some weeks ago but the first one was faulty (poasted about it in this thread):
It's sold by
mobilefun, I don't know who manufactures it but it's high quality in build, if it had a Samsung logo on the back then it could otherwise be an official product. It does come in white too
How does it work?
Initially I thought it would daisy chain alongside the built in battery and give 4400mAh of power but having now fully tested it, it acts like a normal power source (seen as a USB source by the phone as it outputs at 500mA).
The idea is that you would have the bank charged up beforehand and switch the bank on when your phone's battery is low and it will begin charging. Technically you could leave it switched on at all times so as soon as the phone battery drops, it charges back up immediately again but the bottom row light lights on the bank remain active while it is on, I imagine this will drain some of the battery in the bank too so best off using it once the phone's battery gets low.
The bank can also be switched on and off at any time while attached to the phone. The LED on the bank flashes while charging the phone and the number of active LEDs decreases as the charge from the bank transfers to the phone:
Does it add bulk?
Yes! It's 15.5mm thick so adds some bulk to the S3. It's not unacceptably bulky though and you could use it as a full time case as well as it allows full use of all ports on the phone and has a convenient kickstand. It weighs 81 grams.
How useful is it really? It's quite expensive afterall...
It is quite pricey but for many people it's a small price to pay to be able to get power to the phone when a standard power source is not available and you're running low on battery juice.
