In recent months, various global airlines, including Lufthansa Group, have heightened their regulatory measures on portable power banks due to fire safety concerns. Effective from January 15, 2026, Lufthansa Group announced that passengers would no longer be permitted to use or charge power banks during flights. This rule was established to decrease potential fire hazards associated with lithium-ion batteries, which are commonly used in these devices. Additionally, the maximum number of power banks that a passenger can carry on board has been limited to two. This determination aligns with the latest recommendations from the European Union Aviation Safety Agency (EASA) and other international aviation organizations to further bolster safety aboard aircrafts. Airlines such as Emirates, Virgin Australia, and SWISS have already implemented similar restrictions while noting that power banks cannot be placed in overhead compartments, but instead should be stored in seat pockets or kept on the passenger's person. The decision reflects growing global concerns about defective lithium battery-powered devices causing fires both in cabin areas and in hold compartments of aircraft. These incidents can lead to drastic consequences for passenger safety, prompting airline operators to adopt stricter rules around battery-powered devices. Furthermore, airlines outside of Europe have also joined this movement. For instance, Taiwan's EVA Airways has prohibited the use of power banks and spare lithium batteries in its flights, while Singapore Airlines announced similar changes set for April 2025.
