Is a 20000mAh power bank allowed in flight TSA?

Power Banks and Airline Regulations

When traveling by air, it’s important to know what electronic devices are allowed in your carry-on luggage. This includes power banks, which are portable battery packs used to charge electronic devices.

The Transportation Security Administration (TSA) and the Federal Aviation Administration (FAA) regulate the transportation of power banks on airplanes. These regulations are in place to ensure the safety of passengers and crew members.

20000mAh Power Banks

Power banks with a capacity of 20,000 mAh are typically safe to carry on planes. This is because their energy output, usually under 100 Watt-hours (Wh), falls within TSA and FAA guidelines.

Watt-hours (Wh)

Watt-hours are a measure of energy capacity. To calculate the Wh of a power bank, multiply the voltage (V) by the capacity (Ah). For example, a power bank with a 3.7V voltage and a 20,000mAh capacity would have an energy output of 74Wh (3.7V x 20,000mAh).

TSA Guidelines

The TSA allows power banks with a capacity of up to 100Wh in carry-on luggage. Power banks with a capacity over 100Wh but less than 160Wh may be allowed on a case-by-case basis after being inspected by a TSA officer. Power banks with a capacity over 160Wh are not allowed on planes.

FAA Guidelines

The FAA also restricts the use of power banks on planes. Power banks with a capacity of over 27,000mAh are not allowed on planes.

Tips for Traveling with Power Banks

• Check the capacity of your power bank before traveling.
• Keep your power bank in your carry-on luggage.
• Do not charge your power bank while flying.
• If your power bank has a capacity over 100Wh, be prepared to have it inspected by a TSA officer.
• If you have any questions about traveling with power banks, contact your airline or the TSA.
