Hi guys, i need to buy an external battery for my iPhone and don't know witch one i should buy. This new trent seems good but i don't know if there is one better. I would need one with at least 7000mAh and that charged the iPhone as quick as possible.
Apreciate any help, thanks
I prefer the Sanyo Stick Booster:
For every set of these you carry extra, you add 5100mAh to the capacity:
Add the two batteries in the Stick booster on top of that, and it's 7650mAh for one extra set, or 12750mAh for two sets.
