battery low? then just grad one! the hottest stuff in the world. it's world best selling accessory, ever pass over the phone casing and Bluetooth headset.

the power bank is actually a very very large battery pack, ever bigger than your ass. simply grad one, connect your phone, and your phone charged. it can ever revive your dead battery, you know it. one thing you will have to remember that you should make sure the power bank is fully charged before you go aboard (and your phone as well, only dumb will ever forget it hihi)

some power bank with battery pack larger than your ball can ever charged your iPad too! and in case your car broken, it can ever jump start your car! seem amazing?
oops! my phone battery is fucking low. I will need power bank right now!
