Airlines tighten powerbank transport rules after fire incidents

Powerbanks, which use lithium‑ion cells, are classified as a fire risk on aircraft. Aviation authorities and airlines now require that these portable chargers be carried only in the cabin, prohibiting their placement in checked luggage. The rules set capacity limits: devices up to 100 Wh may be taken without special permission, those between 100 Wh and 160 Wh need airline approval, and any powerbank over 160 Wh is not allowed for passengers. Travelers are generally limited to two powerbanks each, and many carriers, such as the Lufthansa Group, forbid charging or using them during flight and mandate storage under the seat or on the person.

Incidents involving lithium batteries have risen, with the U.S. FAA logging 39 cases in 2025 where batteries ignited or generated smoke, prompting evacuations or emergency landings. These safety concerns have driven airlines to adopt stricter guidelines and urge passengers to verify each carrier’s specific policies before travel.
