buying yoobao is quite scary. until now i still duno whether my powerbank is original or not. but its been serving me alright.

bro there is already an existing thread discussing this. and its still on the first page, you just needed to scroll down.

here: powerbank discussion

im using the black transformer one on the right. that is the only power bank i have, and have been using it for the past few months. it does the job, but if anything, i wish its smaller. now its bigger than the phone.
but bigger capacity = bigger size. so no choice.

bro you cant exactly compared it to the speed of charging from wall plug. its portable. just leave it there and charge while you do your own thing. can bring it everywhere anyways.

yeah sort of the same thing here to. after i buy the powerbank i just on all the functions on the phone: data/location services/siri.

usually my phone will last till about 6-7pm if my day starts about 10. so if wanna go out at night den have to rely on powerbank.
