I recently purchased a Xiao Mi Power Bank 10400mAh (which is a great tool – my phone which would barely last 1/2 day on battery has so far been going strong for 4 days charging from the powerbank). However the powerbank only came with a Chinese manual. After searching high and low on the internet I haven’t been able to find an English version of the manual, but I did manage to get some of the key points translated which may help others.

Note: I have added numbers next to each of the LED lights on the picture above which are referenced in the tables below.

Power button

The button that looks like a power button is actually a battery capacity check button. You only need to press this to check the remaining capacity of the device. The device will power itself on and off when you plug/unplug a phone to charge.

The LED lights behave slightly differently in each mode.
