The first battery was for me, before leaving the USA for 1 month. Indispensable with 2 iPhones, GoPro and other devices. Able to plug the iPhone's bro, and mine by taking a Dr Pepper posed quietly, and even walking, it's great. Since I even plug a Galaxy S4. Pruning is not clutter nickel, not thick and not too long. At least 2 charges iPhone 3 GoPro on the same charge this battery before draining. And I think to be an understatement. In short, my brother wanted a return, I took him, he was happy!
