MONTREAL/WASHINGTON, March 27 (Reuters) - The United

Nations aviation agency said the use of power banks, or

portable, rechargeable battery packs, would be limited to two

per passenger on flights effective on Friday as part of new

rules for using the devices while in the air.

Passengers will also be prohibited from recharging the power

banks during flights, the International Civil Aviation

Organization said in a statement.

Airlines such as the Lufthansa Group and countries

like South Korea had already been introducing restrictions on

the use of power banks on flights, following incidents like a

fire on an Air Busan plane in 2025.

The U.S. Federal Aviation Administration was not immediately

available for comment.

Montreal-based ICAO normally sets global standards for

aviation that are mostly approved by its 193-member states,

however the new specifications regarding power banks are

effective immediately.
