Power banks on planes: new 2026 rules on capacity limits and how many you can carry

New regulations on carrying power banks on aircraft came into force in 2026. They must be carried in hand luggage only, not in checked baggage. Power banks up to 100 Wh are permitted without restriction; those between 100 and 160 Wh require airline approval; above 160 Wh is banned. Passengers should also check for the required certification markings.
