Coming Soon: Curbs on Carrying Power Banks on Aircraft
Travelers may soon face stricter rules regarding power banks on airplanes, as airlines and aviation authorities worldwide are tightening regulations due to safety concerns. These changes stem from increasing incidents involving lithium-ion batteries, which are commonly used in power banks, overheating and potentially causing fires.
Heightened Scrutiny and Regulatory Changes
The Federal Aviation Administration (FAA) and other regulatory bodies have long had restrictions on lithium batteries in checked baggage. However, a recent fire incident on an Air Busan flight in January 2025, suspected to be caused by a power bank, has accelerated the implementation of more stringent rules.
Several Asian airlines have already updated their policies. Air Busan, along with other South Korean carriers, now requires passengers to keep portable chargers within arm's reach and prohibits storing them in overhead bins. Airlines such as EVA Air and China Airlines ban the use or charging of power banks during flights. Similar restrictions have been introduced by Thai Airways, Singapore Airlines, Malaysia Airlines, and Cathay Pacific.
In the United States, Southwest Airlines restricts the use of power banks by requiring passengers to keep portable chargers visible at all times while in use. This means that charging devices in a bag or overhead compartment is no longer permitted.
Why the Concern?
Lithium-ion batteries are susceptible to thermal runaway, a rapid, uncontrollable increase in temperature that can lead to fires, explosions, and the release of toxic gases. This is often caused by damage, overheating, manufacturing defects, overcharging or short-circuiting. The FAA has reported a significant increase in battery-related fire incidents, with 84 incidents in 2024 compared to 32 in 2016.
Global Standards and Airline-Specific Rules
While specific regulations vary among airlines, some common guidelines are emerging. Power banks must be carried in carry-on luggage and are not allowed in checked baggage. This allows passengers and crew to quickly respond to any potential fire hazards.
Most airlines permit power banks with a capacity of up to 100 watt-hours (Wh), roughly 27,000 mAh, without requiring special approval. Devices between 100Wh and 160Wh may be allowed with prior airline approval, but anything exceeding this is generally prohibited. Some airlines, like Emirates, allow only one power bank under 100Wh per passenger and prohibit their use during the flight.
Navigating the New Regulations
To avoid issues at the airport, travelers should check the capacity rating of their power banks and ensure they are clearly labeled. It's also crucial to verify the specific policies of the airline they are flying with, as regulations can differ significantly.
In China, a new rule requires power banks to have a China Compulsory Certification (CCC) mark. This regulation is strictly enforced for domestic flights, and power banks lacking the CCC mark may be confiscated.
Adapting to the Changes
These new restrictions may require travelers to rethink how they manage their devices during flights. With some airlines banning in-flight charging, passengers may need to rely on airport charging stations or ensure their devices are fully charged before boarding.
While the changes may seem inconvenient, they reflect a growing emphasis on safety in air travel. By understanding and complying with these regulations, passengers can help minimize risks and ensure a safer flying experience for everyone.
