Carry-on details
Allowed. A car battery charger or trickle-charge maintainer is an electronic device with no battery of its own — it plugs into a wall outlet — so it's screened like any other small electronic item.
Checked-bag details
Allowed. No restriction in checked baggage.
Special instructions
This is different from a car jump-starter, which contains its own spare lithium battery and follows the lithium battery rules instead.
FAQ
- Is a battery charger treated the same as a car jump-starter?
- No — a plug-in battery charger/maintainer has no battery of its own and has no restriction. A jump-starter contains a spare lithium battery and follows those rules instead.
