My answer is this, millet charging treasure button is a little strange way, if we click a charging treasure button, the charging treasure will be fast charging, suitable for charging the mobile phone, if we want to charge the Bluetooth headset, only need to quickly click the button twice, the charger will become a trickle charging mode charging speed will be very slow, suitable for us to charge the headset
Xiaomi charging treasure is not equipped with a power switch, similar to the power button is actually a power view button. Press to display the amount of power in the current power supply. When you need to charge your phone, just plug it directly into the USB port. The use of Xiaomi charging treasure is very simple, small partners can directly connect to the computer to charge it, you can also use a mobile phone charger to charge.
