Carry-on details
Allowed. A bottle warmer travels through security like any small electric appliance — no liquid restriction applies to the warmer itself (any milk or formula inside is covered separately by the baby-liquids exception). You may be asked to remove it from your bag for a clearer X-ray image.
Checked-bag details
Allowed. No restriction in checked baggage. If it runs on a battery pack, keep any spare lithium batteries in carry-on per the lithium battery rule.
Special instructions
TSA doesn't publish a dedicated listing for bottle warmers — this follows the general rule for small electric appliances. Contact AskTSA if you have an unusual model.
