Several airlines have started strictly enforcing a safety rule that restricts the use of power banks during flights, citing fire hazards linked to lithium-ion batteries. The move follows global aviation safety guidelines and recent incidents involving battery overheating and smoke on board aircraft.
Under the enforced rule, passengers are not allowed to use power banks to charge mobile phones, laptops, or other electronic devices while the aircraft is in the air. In many cases, airlines are also asking passengers to keep power banks switched off and safely stored in their carry-on baggage throughout the journey. Power banks remain prohibited in checked-in luggage.
Airlines have clarified that the restriction is focused on usage, not carriage. Most carriers still permit passengers to carry power banks in cabin baggage, subject to capacity limits—typically up to 100 watt-hours without special approval. Devices exceeding this limit may require airline permission or may be completely barred.
Aviation safety experts say lithium-ion batteries pose a significant risk if they malfunction mid-air, as thermal runaway can lead to fire or smoke that is difficult to contain in a confined cabin environment. “Even a small battery failure can escalate quickly at cruising altitude,” an aviation safety official noted.
Passengers have been advised to fully charge their electronic devices before boarding and to rely on in-seat USB ports or power outlets where available. Airlines are also urging travelers to check individual carrier guidelines before flying, as enforcement and specific limits may vary.
With air travel steadily increasing, airlines say the tighter enforcement is a preventive step aimed at ensuring passenger safety rather than causing inconvenience. Announcements regarding the restriction are now being made during pre-flight briefings, signaling that the rule is set to remain a standard part of in-flight safety protocols.
