Can you bring white noise sound machine on a plane?

Version covered

A sound machine may contain a rechargeable battery, speakers and a timer; switch it off and protect its controls. This answer covers the ordinary form of the item at a US checkpoint. A separate liquid, battery, blade or chemical in the kit may have its own rule.

Which Hatch sound machines have batteries?

Hatch confirms that Rest Go and Rest+ have internal rechargeable batteries, while Rest Classic, Rest Mini, Rest 2nd Gen, Restore and Restore 2 need external power and have no internal battery. That distinction answers the first packing question: a Rest 2nd Gen does not need a battery Wh check, but a Rest Go does. Hatch does not state the Rest Go's Wh rating on that support page, so check the label or its exact manual if your airline asks for it.

Carry-on baggage

Yes, subject to battery limits. “White noise sound machine” with an installed battery may travel in carry-on; protect any loose spare lithium cell and keep it in the cabin.

Checked baggage

Yes, if powered off and protected from damage. “White noise sound machine” with an installed battery may be checked within FAA limits; spare lithium batteries and power banks may not be checked.

Prepare for screening

• Record the model and power source. Separate any loose battery or power bank and protect the screen, connectors and switches.
• Inspect the kit and its packaging.
• Compare the result with airline and route conditions.
