I checked with airlines websites about regulations on lithium battery with capacity under 100WH. They didn’t state the quantity limitation for battery with capacity less than 100WH. I am wondering if I can carry 3 of my 99WH power banks with or without special procedure? My trip are usually between US and Japan.


Per IATA rules you are allowed to carry up to 20 such power banks. They must be isolated and in your carry-on luggage.

Note that those are IATA guidelines, individual airlines are allowed to deviate from that, so you should check the airline’s rules.

    I guess that would be the total number of power banks and spare batteries including such things as DSLR batteries, drone batteries and so on. Apr 26 at 20:58
