Airlines Tighten Rules on Portable Chargers

Airlines worldwide are imposing stricter rules on portable chargers and power banks as safety concerns over lithium-ion batteries grow. While these devices have become a travel essential, a series of fires and near misses have transformed them from convenience items into regulated hazards.

The main danger stems from thermal runaway—a self-sustaining reaction in lithium-ion batteries that can lead to overheating, ignition, and intense fires in the confined environment of an aircraft. Incidents on KLM and Virgin flights this year highlighted the risk, prompting carriers to reassess their policies. Experts note that while most lithium batteries are safe, cheaper power banks often lack internal safeguards found in certified devices.

U.S. airlines follow Federal Aviation Administration guidelines allowing passengers to carry power banks only in cabin baggage. United permits up to two batteries of 160 watt-hours or less, while Delta and American allow unrestricted carriage under 100 Wh but require airline approval for 101–160 Wh units. Southwest adds an extra rule: power banks in use must be visible and outside any bag.

International carriers are going even further. Emirates has banned the use of all power banks on board effective October 1, 2025, though one unit under 100 Wh may still be carried in hand luggage. Singapore Airlines and British Airways also prohibit in-flight use and restrict higher-capacity models.

These measures aim to minimize fire risks and ensure quick crew response in case of battery failure. Travelers should check their airline’s policies carefully before flying to avoid surprises at the gate.
