As summer travel season approaches, passengers should be aware of updated airline guidelines regarding lithium ion power banks. These portable battery chargers, popular for keeping devices charged on the go, have come under scrutiny following several incidents involving smoke or fire.

New Safety Guidelines

The Federal Aviation Authority (FAA) and international aviation authorities have implemented stricter rules to mitigate risks associated with lithium ion batteries. Travelers are now required to carry these power banks in their carry-on luggage, rather than checked baggage. This change allows cabin crew to quickly address any potential overheating or fire incidents.

Passengers can generally bring two lithium ion power banks with a capacity of up to 100 watt hours without needing airline approval. For larger batteries, such as those used in professional equipment, airline approval is necessary. It’s important to check the watt-hour rating on your battery, which is often labeled on newer models. If not, the FAA provides an online calculator to help determine this.

Risks and Precautions

The concern over lithium ion batteries stems from their ability to store significant energy in a compact space. If a battery is damaged, overcharged, or overheated, it can trigger a chemical reaction known as ‘thermal runaway,’ which produces heat and toxic gases. To prevent such incidents, travelers should inspect their power banks for damage and avoid using cheap, unverified brands.

Airlines have also set rules for handling power banks during flights. They should not be stored in overhead bins but kept accessible, such as in a seatback pocket. Charging devices using the aircraft’s power sockets is discouraged, and if a device slips between seats, passengers should alert cabin crew rather than attempt retrieval themselves.

Check with Your Airline

Since individual airlines may have more restrictive policies, it’s advisable to verify specific rules with your carrier before traveling. For instance, Southwest Airlines recently limited passengers to one charger each. By staying informed, travelers can ensure compliance with safety regulations and avoid disruptions during their journey.
