Airlines worldwide are implementing stricter regulations on power banks following recent in-flight fire incidents linked to lithium-ion batteries. The International Air Transport Association (IATA) has updated its safety protocols, prompting many carriers to enforce new rules.​

On January 28, 2025, an Air Busan Airbus A321 caught fire at Gimhae International Airport, South Korea. Investigators determined that a power bank likely caused the fire.

Subsequently, South Korea’s Ministry of Land, Infrastructure, and Transport (MLIT) mandated that from March 1, 2025, passengers must carry power banks on their person, and charging devices during flights is prohibited. Additionally, storing power banks in overhead compartments is banned, and each passenger is limited to five devices.​

Other airlines have followed suit. Thai Airways and AirAsia have prohibited the use or charging of power banks onboard since March 15, 2025. EVA Air and China Airlines have also banned power bank usage during flights.

Hong Kong Airlines implemented a policy requiring power banks to be stored in carry-on baggage and prohibiting their use during takeoff, landing, and taxiing.

The International Civil Aviation Organization (ICAO) and IATA have established guidelines for carrying lithium batteries:​

Power banks up to 100 watt-hours (Wh) are allowed in carry-on baggage without approval.

Devices between 100 Wh and 160 Wh require airline approval.

Power banks over 160 Wh are prohibited on passenger aircraft.​

Passengers are advised to keep power banks in carry-on luggage, avoid using or charging them during flights unless permitted, and ensure devices are in good condition to prevent overheating or fires.​

These measures aim to enhance in-flight safety by mitigating the risks associated with lithium-ion battery malfunctions, which can lead to overheating or fires in the confined cabin environment.
