Power Bank Restrictions on Flights: A Guide for Travelers

Power banks have become an essential travel accessory, providing convenient charging for electronic devices while on the go. However, when it comes to air travel, there are specific regulations in place regarding the size and capacity of power banks allowed on flights.

Understanding Power Bank Capacity

The capacity of a power bank is measured in watt-hours (Wh). This value represents the amount of energy the power bank can store and deliver. Power banks with higher Wh ratings can charge devices for longer periods or charge multiple devices simultaneously.

Carry-On Restrictions for Power Banks

Most airlines allow power banks with capacities up to 100Wh to be carried on board in carry-on luggage. This includes standard-sized power banks commonly used for smartphones, tablets, and laptops.

Larger Power Banks (100-160Wh)

Power banks with capacities exceeding 100Wh but not exceeding 160Wh are generally subject to airline pre-approval. Travelers must contact their airline in advance to request permission to carry larger power banks.

Pre-Approval Process

To obtain pre-approval for a larger power bank, travelers may need to provide the airline with the following information:

• Power bank brand and model
• Power bank capacity (Wh)
• Device(s) to be charged
• Intended purpose for the power bank

Packing and Storing Power Banks

When packing a power bank for a flight, it is important to follow these guidelines:

• Store power banks in carry-on luggage only.
• Protect power banks from damage by wrapping them in bubble wrap or padding.
• Avoid packing power banks in checked baggage.

Prohibited Power Banks

Power banks with capacities exceeding 160Wh are prohibited on all flights, regardless of carry-on or checked baggage status.

Additional Tips

• Check the airline's specific regulations for power bank restrictions before traveling.
• Consider using smaller power banks that fall within the 100Wh carry-on limit.
• If carrying a larger power bank, contact the airline well in advance to obtain pre-approval.
• Ensure that the power bank is in good condition and has no visible damage.
