You are allowed a portable charger that's rated up to 100 watt-hours. Anything over that and you need permission from the airline. To Calculate Watt Hours in Power Banks, it's simple math.

Milliamp Hours/1000 x Voltage = Watt Hours
(mAh)/1000 x (V) = (Wh)

For example, if you have a 10,000mAh portable charger you want to bring on a plane:
