Wh (watt hour), mAh (milliampere hour), w (watt) is the unit of power, mA is the unit of current, power=voltage x current, therefore, wh=voltage xAh, for mobile phone automatic power supply, the battery voltage is generally 3.7v, so wh=3.7xAh, a charging bank with a capacity of 10000mAh, the capacity converted to wh is 3.7x10Ah=37wh
10400 divided by 1000 times 5V is equal to 52Wh, less than 100Wh, which complies with the regulations of the Civil Aviation Administration and can be taken on the aircraft.
