Some fancy toothbrushes have UV sanitizers or charging cases that plug in. Those are totally fine too, as long as the battery is built-in and under the watt-hour limit. But if your case has a separate power bank inside, check the airline rules—it might count as a spare battery, which has different rules (like being in your carry-on).
Oh, and the charging cable? Bring it. It’s just a wire, no more dangerous than a shoelace. Just don’t use it to tie up the person next to you who’s hogging the armrest. That’s a different kind of problem.

Can You Take an Electric Toothbrush in Carry-On or Checked Luggage?
Security Screening Shenanigans
Going through security? Your electric toothbrush will not set off alarms unless it’s wrapped in a giant ball of foil. It’s small, it’s plastic, it’s harmless. The TSA agent will probably glance at it, yawn, and move on to the guy with a bag full of protein powder. (Pro tip: that’s the real suspicious stuff.)
But here’s a fun little jab: if you ever get asked to remove your toothbrush for inspection, just smile and say, “It’s for the plaque, officer,” and watch them try not to laugh. It’s the closest thing to a dad joke that actually works at 5 AM.
