## Key points

- TSA rules allow AirTags in luggage.
- Their coin cell contains less than 0.1 grams of lithium.
- Tracking depends on nearby Apple devices.

## Summary

TSA rules permit AirTags in luggage: their small, non-rechargeable battery contains far less lithium than the limit for lithium metal batteries. This means travellers can use them to help locate bags without falling foul of the battery restrictions described in the article.

An AirTag uses a CR2032 coin cell containing less than 0.1 grams of lithium, compared with the US limit of 2 grams. The article says international rules also allow devices in checked baggage to remain on if they contain under 0.3 grams of lithium; it notes that AirTags rely on nearby Apple devices and may not work as well everywhere.
