Can I bring a battery powered toothbrush on a plane?

But if you're new to electric toothbrushes, you may wonder, ?Can I pack an electric toothbrush in a carry-on?? The Transportation Security Administration (TSA) says yes. Electric toothbrushes can be packed in carry-on or checked luggage.



Yes, you can bring a battery-powered or rechargeable electric toothbrush on a plane in 2026, and it can be placed in either your carry-on or checked luggage. Because most modern electric toothbrushes (like those from Sonicare or Oral-B) use small lithium-ion batteries that are "built-in" to the device, they are generally exempt from the strict "lithium battery in checked bags" ban that applies to large power banks or laptop batteries. However, the TSA and international security agencies strongly recommend keeping them in your carry-on. This prevents the toothbrush from accidentally turning on and "vibrating" inside your suitcase, which can trigger a security search or deplete the battery. If you do check it, ensure the "on" switch is protected or remove the brush head to prevent accidental activation during the baggage handling process.
