after few days in using xiaomi powerbank. i found it able to charge my xperia ZL 2350mAh for 3 times.. everytime i charge is around 10% up to 100% and its will auto stop after certain full charged period..

if according to formula, 10400 x 3.6V / 5V = 7488mAh. with conversion around 90%. then left only 6739mAh.. divided by phone 2350mAh only 2.8 times.. i feel yes.. the battery have done what's it claimed by xiaomi..
