The rated energy must not exceed 160Wh, equal to how many mah battery capacity?

The rated energy must not exceed 160Wh, equal to how many mah battery capacity?
The action power supply capacity indicator, correct should be marked with WHR (WH) watt hour, but the volume of the advertised power supply is usually used Xx000mah
WHr watt Hour, which is the operational power output power unit, P (WHR) =v voltage x I (capacitance AH).
The general lithium battery voltage is 3.7V, so 160Whr conversion into electric capacity mah algorithm is 160/3.7*1000=43,243mah; The WHR is 27,027mah.
Due to the power output voltage is 5V, the other algorithm is 160wh=32,000mah; 1000wh=20,000mah.
In short, as long as the capacity of the action power not more than 20,000mah, must be able to pass.
