Which power bank is not allowed in flight?

Permissible Power Banks for Air Travel

Air travel regulations impose specific restrictions on the type of power banks passengers can carry onboard. Adhering to these guidelines is crucial for safety and avoiding potential penalties.

Prohibited Power Banks:

Lithium-ion battery packs with a watt-hour (Wh) rating exceeding 160 Wh are strictly prohibited in flight. This prohibition applies to both carry-on and checked luggage.

Restricted Power Banks:

Power banks with a Wh rating between 101 and 160 Wh require prior approval from the airline before being allowed onboard. Passengers must contact their airline and declare the power bank in advance to obtain the necessary authorization.

Permissible Power Banks:

Power banks with a Wh rating below 100 Wh generally meet airline regulations and can be carried in both carry-on and checked luggage. However, it is advisable to check with the specific airline for any additional restrictions or requirements.

Determining the Watt-Hour Rating:

The Wh rating of a power bank is typically indicated on the device itself or in the manufacturer’s documentation. If the Wh rating is not readily apparent, use the following formula:

Wh rating = Voltage (V) x Capacity (Ah)

For example, a power bank with a voltage of 5V and a capacity of 20,000mAh (or 20Ah) would have a Wh rating of 100 Wh, which is within the permissible limit.

Additional Tips for Air Travel with Power Banks:

• Always carry the power banks in their original packaging or a protective case.
• Ensure the power banks are fully charged before travel.
• Keep the power banks easily accessible in your carry-on luggage for inspection.
• If the power bank triggers security concerns during the screening process, cooperate with the authorities and provide any necessary information.

By following these guidelines, passengers can ensure their power banks are permitted on their flight and avoid any unnecessary delays or inconvenience during air travel.
