# Aviation safety regulations for lithium power banks > Live situation record from CLSTR: https://clstr.news/situations/aviation-safety-regulations-for-lithium-power-banks > Updated: 2026-10-12T04:52:57.000Z. Sources: 5. Developments: 2. Aviation safety regulations and warnings regarding lithium-ion power banks have intensified following several in-flight incidents involving battery fires and explosions. These incidents, including emergency diversions for Lufthansa flights and a flight to Curaçao, have prompted the International Air Transport Association (IATA) to establish strict guidelines to prevent overheating. Authorities, including the UK’s Civil Aviation Authority (CAA) and Wizz Air, have issued specific directives to mitigate the risk of thermal runaway. Passengers are prohibited from carrying power banks, spare lithium batteries, or e-cigarettes in checked hold luggage, as these items must remain in cabin baggage. To prevent short circuits, it is recommended that travelers store these devices in original packaging or separate plastic bags. Furthermore, passengers are advised against using in-flight power outlets or USB ports to charge power banks and may face limits on the number of devices permitted per person. ## Timeline ### 2026-10-12: Aviation authorities warn against packing power banks in hold luggage Airlines and aviation authorities warn that power banks and lithium batteries must be kept in cabin baggage only, as they pose significant fire risks if placed in checked hold luggage. 2 sources. https://clstr.news/cluster/aviation-authorities-warn-against-packing-power-banks-in-hold-luggage ### 2026-10-04: Aviation safety rules tighten following powerbank incidents Aviation authorities are tightening powerbank regulations following several in-flight battery explosions and fires.
