Since January 15, 2026, airlines in the Lufthansa group have banned the use of external batteries, such as portable chargers, during flights. This rule is not exclusive to Lufthansa; Air France has also adopted the same policy. The decision follows growing concerns about the safety risks associated with lithium-ion batteries, which are commonly used in portable chargers and can overheat or catch fire under certain conditions. The new regulation applies to all flights operated by Lufthansa and its subsidiaries, as well as Air France. Passengers are now required to ensure their devices are fully charged before boarding. Airlines have advised travelers to use charging stations available at airports or to charge their devices at home prior to departure. The move comes amid increased scrutiny of electronic devices on flights, particularly after several incidents involving overheating batteries in the past decade. Aviation authorities have been working closely with airlines to establish stricter safety guidelines. These measures aim to reduce the risk of in-flight fires and ensure passenger safety during air travel. This policy is part of a broader trend in the aviation industry to enhance safety protocols related to electronic devices. While the restrictions may be inconvenient for some travelers, they are intended to prevent potential hazards. Airlines continue to monitor the situation and may adjust their policies based on new safety recommendations or technological advancements.
