GoKawiilTSA lithium-battery rules clarified amid growing airline restrictions on power banks
Lithium-ion batteries can suffer thermal runaway, an uncontrolled overheating reaction that can cause smoke, fire or shrapnel, and the FAA has logged over 700 such incidents since 2006, nearly 40% involving portable chargers. The TSA requires devices with lithium metal or lithium-ion batteries to be carried in cabin baggage rather than checked, and several airlines and regulators have added their own stricter rules on power banks specifically.
GoKawiil's interpretation of the reporting above, not reported fact.
The growing patchwork of airline- and country-specific rules means travelers can no longer assume one blanket policy applies everywhere, making it important to check individual carrier and national regulations before flying. The focus on portable chargers suggests regulators see them as a particular risk point compared to other lithium-powered devices like phones or laptops.
- Thermal runaway in lithium-ion batteries can cause fire, smoke or shrapnel, especially dangerous in aircraft cabins.
- TSA mandates lithium battery devices go in carry-on, not checked luggage, due to cargo hold fire risks.
- Airlines like Southwest limit chargers per passenger, while Virgin Australia, Qantas and Jetstar ban their use entirely onboard.
Apple AirTag 4-Pack — Since AirTags use a small coin-cell battery (not lithium-ion), they're perfectly fine to toss in checked or carry-on luggage per TSA rules, making them an easy way to track your bag's location. They're great travel companions for peace of mind, especially if your luggage gets lost in transit.
