旅行時の充電必需品

The largest TSA-approved power bank is typically limited to 100Wh (watt-hours) per device for carry-on luggage. This ensures safe transport on airplanes while providing enough capacity to charge smartphones, tablets, and other portable devices multiple times. Power banks above 100Wh usually require airline approval.

When choosing a large TSA-approved power bank, check the watt-hour rating and airline regulations. A high-capacity, certified power bank ensures safe, efficient charging while traveling, making it ideal for long flights or trips where outlets may not be available.

Carrying a power bank in checked luggage is prohibited by airlines and TSA regulations because lithium-ion batteries can short-circuit, overheat, or even catch fire under pressure and temperature changes in the cargo hold. If discovered, airport security may remove the power bank, delay your flight, or issue a fine.

To stay safe, always carry your power bank in your carry-on luggage. Make sure it complies with airline watt-hour limits and is a certified model. Keeping it in your carry-on not only minimizes safety risks but also allows you to easily charge your devices during the flight.

To travel safely with a power bank, always protect the terminals to prevent short circuits. You can cover them with tape, keep the power bank in a case, or place it in a plastic bag. Most airlines allow power banks up to 100 watt-hours (Wh), while larger batteries between 101–160 Wh require airline approval.

Carry your power bank in your carry-on luggage, never in checked bags, and use certified, high-quality models. Avoid exposing it to extreme heat or moisture, and unplug it when fully charged. Following these steps ensures safe, reliable charging while traveling.
