GoKawiilTSA reiterates carry-on-only rules for power banks and lithium batteries
TSA guidance highlights that portable power banks and devices with built-in batteries, such as laptops, cameras and smartwatches, must travel in carry-on luggage rather than checked bags. The limit for lithium-ion batteries is 100 watt-hours, calculated via mAh times voltage divided by 1,000, though batteries up to 160Wh may fly with airline approval and a two-item cap. Non-rechargeable lithium metal batteries, like AA cells, are allowed up to 2 grams of lithium content per battery.
GoKawiil's interpretation of the reporting above, not reported fact.
The rules exist because lithium batteries can overheat and ignite, a risk that is harder to detect and contain in a cargo hold than in the cabin. Travelers unaware of watt-hour limits or packing requirements could face confiscation at security checkpoints or delays, so checking device specifications before a trip could save hassle.
- Power banks and devices with built-in batteries must go in carry-on bags, not checked luggage.
- Lithium-ion batteries are capped at 100Wh; higher-capacity units need airline approval and are limited to two per traveler.
- Non-rechargeable lithium metal batteries are allowed up to 2 grams of lithium content and should stay in original packaging.
