Power Banks: Carry-On Allowed, Charging Prohibited on Flights

Power banks, or portable chargers, are like small banks for electricity.

They store energy and give it to your phone.

The rules say you can take them on the plane in your bag, but you can't use them to charge your phone during the flight.

The reason is because power banks have a rechargeable battery and circuits to control the power.

This is especially helpful when wall outlets are not available.

This is the basic gist of the regulations regarding power banks.
