The Civil Aviation Authority of Thailand (CAAT) has introduced new rules governing the transport and use of portable battery packs, commonly known as power banks, on board aircraft. The restrictions apply to all passengers departing on flights from Thailand and are intended to enhance aviation safety.
Under the new CAAT regulations, power banks are prohibited in checked baggage and may only be carried in hand luggage. Devices with a capacity of up to 100 Wh are allowed without prior approval, while power banks rated between 100 Wh and 160 Wh require approval from the airline.
Power banks without manufacturer labels or clearly marked capacity ratings are not permitted. To reduce the risk of short circuits, passengers are advised to store batteries in protective cases, separate compartments, or their original packaging and to avoid contact with metal objects.
- Power banks are permitted only in carry-on baggage.
- Using or charging power banks during the flight is prohibited.
- Devices with a capacity of up to 100 Wh are allowed without approval.
- Passengers may carry no more than two power banks.
In-Flight Use Prohibited
One of the most significant changes is a complete ban on using power banks during flights. Passengers are no longer allowed to use them to charge mobile phones, tablets, laptops, or other electronic devices while on board. Power banks may not be connected to the aircraft’s electrical outlets or USB ports for recharging.
The rules also introduce new storage requirements. Power banks must not be placed in overhead bins and should remain in an easily accessible location, such as a personal bag under the seat or in the seat pocket. This allows cabin crew to respond more quickly in the event of overheating, smoke, or other battery-related incidents.
Why the Rules Are Being Tightened
According to CAAT, the new measures are based on international aviation safety recommendations adopted following several incidents involving lithium-ion batteries on aircraft. Such batteries can pose a fire risk if damaged, overheated, or used improperly.
The regulator also noted that individual airlines may impose additional restrictions on carrying power banks. Violations of Thailand’s aviation safety regulations may result in penalties of up to 60,000 baht or imprisonment for up to two years.
