This cluster discusses FAA and TSA regulations on lithium-ion battery capacities (e.g., 100Wh limits) for carry-on luggage on airplanes, including fire hazards, device compatibility, and travel workarounds.

IIRC there's a legal limit on the allowed capacity of a Li-ion battery in a device on an airplane, yes. That might be related.
Per FAA, this is correct. Obviously other jurisdictions may varyhttps://www.faa.gov/hazmat/packsafe/resources/media/Airline_...
How big are the batteries for these things? Aren’t they a fire hazard? I’m surprised the airlines allowed them aboard.
Yeah, they don’t allow big batteries on carryon and nothing in checked out luggage. How are people travelling with these?
US airlines might choose to approve 160 Wh batteries: https://www.faa.gov/hazmat/packsafe/resources/media/Airline_...
Do people not fly with a USB battery on trips these days?
Have a high-capacity laptop battery for normal use and a cheap, lower capacity 100Wh one you can swap in to take on flights.
There are FAA limits on how big a battery can be if you want to take it on a plane. Your best bet is probably an external battery.
Lithium ion capacities are limited by the FAA to 100Wh per device, so it's not that.
After all, you're explicitly restricted from bringing large Li-ions on planes!https://www.tsa.gov/travel/security-screening/whatcanibring/...
