Strict regulations on lithium battery backup chargers when traveling by plane

Lithium batteries are found in many personal electronic devices and pose a high risk of explosion, so many airlines strictly manage them.

From October 1, 2025, 13 international airlines including Emirates, Singapore Airlines, EVA Air, Thai Airways, AirAsia, Air Busan, China Airlines, Korean Air, Cathay Pacific, Hong Kong Airlines, Tigerair, Starlux and Asiana Airlines issued a ban on the use of lithium backup batteries on planes for personal electronic devices such as phones, laptops, tablets...

Of these, four airlines, including Singapore Airlines, Thai Airways, AirAsia and Cathay Pacific, are operating flights to and from Vietnam. This means that Vietnamese passengers who regularly fly internationally or transit at regional aviation hubs will be directly affected by the new regulations.

Previously, in February 2025, Vietnam Airlines also announced the decision to ban the use of lithium backup batteries on all VAG flights, including Vietnam Airlines, Pacific Airlines and Vasco. The decision to ban the use of lithium backup batteries was made by Vietnam Airlines to ensure maximum safety for passengers and crew.

Vietnam Airlines also equips specialized tools such as heat-insulated gloves and special fire-proof and smoke-proof bags on board to respond in case of incidents related to lithium batteries.

Vietjet Air also requires passengers not to charge power banks in any form, nor to use power banks to charge personal devices during the flight.

Aviation experts confirm that this regulation does not prohibit the carrying of spare batteries, but prohibits their use during the flight. Passengers can still carry standard batteries, as long as they are placed in an easily visible location and separate from their carry-on luggage. Authorities recommend checking each airline's regulations carefully before departure to avoid being refused transportation.

According to the International Civil Aviation Organization (ICAO), lithium batteries are considered high-risk items because they can generate heat, short circuit or explode when damaged. Recently, many airlines have recorded incidents of spare batteries emitting smoke, causing fires in the cabin, forcing planes to make emergency landings.
