Carry-on details
Allowed with conditions. Car jump-starter power packs use lithium batteries, often 100–160 Wh or higher, so most require airline approval before your flight, and any unit over 160 Wh is not allowed at all.
Checked-bag details
Not allowed. Like all spare lithium batteries, these are prohibited in checked baggage.
Quantity limit
100 wh (per item)
Special instructions
Check the printed Wh rating before you fly — many jump starters exceed 100 Wh and will need airline approval in advance.

FAQ
- Will airport security let me bring a car jump starter?
- It depends on its watt-hour rating. Many jump starters exceed 100 Wh, which means you need airline approval in advance, and anything over 160 Wh isn't allowed on passenger flights at all.
