In summary: Most portable stations exceed passenger lithium-battery limits; watt-hours and airline approval govern carriage.
The rule that actually governs this
Airlines and aviation regulators classify portable power stations by their lithium battery watt-hour rating, not by physical size or brand. In the US, FAA guidance generally requires airline approval to carry a battery rated 101-160Wh, and prohibits batteries above 160Wh from passenger flights entirely, whether in carry-on or checked baggage.
Why most mid-size and larger stations are affected
A 1kWh-class power station, roughly 1,000Wh capacity, is far above the 160Wh passenger limit -- this rules out air travel for most of the higher-capacity stations marketed for home backup or extended camping, even though smaller phone-charger-sized power banks, typically well under 100Wh, usually travel without issue.
What to check before flying with any battery-powered device
Confirm the exact Wh rating printed on the unit or its documentation, not just the marketed capacity class, check the specific airline's policy since some apply stricter limits than the regulatory minimum, and never pack spare or uninstalled lithium batteries in checked luggage -- they must go in carry-on if permitted at all.
- Batteries above 160Wh are generally prohibited for passengers.
- Spare batteries must not be checked.
