The Mi Power Bank comes with a 10,400mAh lithium-ion battery (at 3.6V for 37.44Wh), sourced either from LG or Samsung (as stated by Xiaomi). If you’ve read our power bank buying tips article, you’ll know that due to power lost during voltage conversion, along with other factors like circuit resistance, the number of recharges you can get from a power bank isn’t simply a division of its capacity and your device’s battery capacity. According to Xiaomi, the Mi Power Bank is able to recharge the Mi 3 smartphone 2.5 times, the iPhone 5S smartphone 4.5 times, and the iPad Mini tablet 1.5 times. These numbers seem to be quite accurate, as we managed to top up the charge of an iPhone 5S (that has a 1,560mAh battery) four times, and still had a bit of charge left on the power bank.
