Ask HN: Can you end up on the “No Fly” list for putting AirTags in your luggage?

[benguild]

These have batteries inside, which are not allowed in checked bags.

[devoutsalsa]

Lithium batteries with 100 watt hours or less in a device

They seem fine to take in checked luggage.

Electric toothbrushes, shavers, etc are all fine in checked luggage and their batteries are many times larger. There's nothing wrong with batteries so long as they don't surpass a certain size.

[benguild → Etheryte]

Vapes aren't

[orbz → benguild]

That’s because for a period of time they were poorly manufactured and quite literally exploded. Since there were no real brands as they were imported before they became mainstream they just blanket banned them all.

There have been other devices banned for similar reasons, like the Samsung Galaxy Note7: https://www.transportation.gov/briefing-room/dot-bans-all-sa...

Airlines mostly dislike 20,000 mAh power banks that can self-ignite in the checked-in luggage.

If they detect something like that in your luggage, they will kindly ask you to take it in the cabin.

They never cared about CR2032 cells.

Of course you can put these in checked bags. These contain tiny primary cells. TSA will issues with only Lithium batteries over 100wh.

Batteries are not allowed in checked bags? I must have unintentionally broken this rule many times by bringing my electronics

[orra → dmak]

You can check in laptops; OP clearly misunderstands. https://www.tsa.gov/travel/security-screening/whatcanibring/...

There are stricter rules however for spare batteries, including power banks. https://www.tsa.gov/travel/security-screening/whatcanibring/...

[djtango → dmak]

If it's large enough they may pick it up - I wasn't allowed to board a flight once because they found a powerbank in my suitcase.

I got stopped at security and was shown my luggage. After removing the power bank it was all good, luggage was put onto plane and I was allowed to board.

Battery bank of certain size is not allowed. General batteries inside device is normally fine

[voidbert]

Having more than 100mL of liquid is also not allowed, but you won't get on the no fly list for that. They'll just ask you to throw it out. Not sure about airtags, but it could be the same.

[tamimio → voidbert]

You can say that liquid for medical purposes and they will run few tests on it before allowing it.

[skeeter2020 → voidbert]

This isn't true for checked luggage; you're thinking about carry-on.

[pmorici]

The AirTag uses a primary coin cell battery (aka non-rechargeable) those are generally not prohibited in regulations like rechargeable lithium batteries are.

[theshrike79]

Where did you get the information that batteries are not allowed? Please post a source for that claim.

[tamimio]

This is like saying you can’t wear a watch on board because it has a battery..
