The Lufthansa Group announced that the use of power banks is now prohibited on board it's aircrafts, including flights operated by Lufthansa, SWISS, Austrian Airlines, Brussels Airlines, ITA Airways, and Eurowings. Travelers are allowed to carry up to two power banks on board (each under 100 watt-hours), but they may not be used to charge other devices or be charged using the aircraft’s power source.
Additionally, power banks may not be placed in the overhead storage bin or in checked luggage. They must be placed in the seat pocket or in a bag under the seat in front of the traveler.
Numerous other airlines, including Qantas, Emirates, and Cathay Pacific, have implemented similar policies due to the increased risks associated with lithium batteries onboard.
