New international flight safety rules for power banks

Stricter global regulations for the transport and use of power banks have been introduced by the International Civil Aviation Organization (ICAO) in response to recurring safety incidents. As of March 2026, passengers are prohibited from charging or using external power banks during flights, with a limit set on carrying a maximum of two units in carry-on luggage.

The policy shift follows a series of mid-air emergencies, including a recent incident where a Lufthansa flight was diverted to Lyon after a passenger's power bank caught fire. While the crew managed to contain the hazard using a specialized fire-retardant bag, the event underscores the persistent risk posed by lithium-ion batteries in high-altitude, pressurized environments.

Major carriers, including Lufthansa, Eurowings, and Swiss Air, have updated their safety protocols accordingly. Power banks remain strictly forbidden in checked baggage. Within the cabin, these devices must be kept within reach and are not to be stored in overhead bins, where fire detection and suppression are more difficult. Devices exceeding 100 Wh capacity generally require prior airline approval.

According to aviation authorities such as the FAA and the UK's CAA, the proliferation of battery-powered consumer electronics—often numbering in the thousands on a single wide-body jet—has necessitated these increased safety measures. Passengers are urged to consult their airline’s specific restrictions before traveling to ensure compliance.
