Tougher rules for on-board external batteries

14 Jan 2026 | Airlines

From January 15, Lufthansa Group airlines will be applying new rules governing the carriage and use of external batteries on board their aircraft. These measures are designed to enhance passenger and crew safety.

External batteries, commonly known as powerbanks, contain lithium batteries which can present a fire hazard in the event of a short-circuit. The new provisions are part of a preventive approach and comply with the recommendations of international aviation authorities.

Prohibited use on board

From now on, the use of external batteries in flight will be strictly regulated. It will no longer be permitted to charge personal electronic devices using an external battery during a flight.

It is also forbidden to recharge an external battery by plugging it into the aircraft’s power supply, whatever the class of travel.

Transport conditions for external batteries

Each passenger can carry a maximum of two external batteries. They may no longer be stowed in overhead luggage compartments.

External batteries must be :

  • worn,
  • placed in the seat pocket,
  • or stowed in a carry-on bag under the front seat.

The carriage of external batteries in the hold remains strictly forbidden.

Battery capacity and specific approvals

The maximum capacity allowed for an external battery is 100 Wh.

Batteries with a capacity of between 100 Wh and 160 Wh can only be accepted with prior authorization from the airline.

Special cases and equipment concerned

The use of external batteries to power essential medical devices remains authorized on board.

The same transport and use rules also apply to electronic cigarettes, which also contain lithium batteries.

Regulations based on international recommendations

These measures are based on current recommendations from leading international aviation authorities, includingEASA, FAA,IATA andICAO.

Travelers are advised to check these rules before departure, and prepare their luggage accordingly to avoid any inconvenience when boarding or on board.
