Yes, you can. But—and this is a big, fluffy, airline-shaped but—there are rules. Most airlines allow electric toothbrushes in checked luggage. Most. The key word here is “most,” not “all.” So don’t just assume and toss it in like a pair of dirty socks.
The real issue? Batteries. Lithium-ion batteries are the divas of the travel world. They have opinions. They can’t be in the hold if they’re loose or over a certain size. Your toothbrush’s battery is tiny—usually under 3 grams of lithium—so it squeaks by. But check your airline’s specific policy. I know, I know, more homework. But your luggage won’t self-destruct.
What Could Go Wrong? (Cue Dramatic Music)
Imagine this: your toothbrush turns on in the dark of the cargo hold. It’s vibrating against a suitcase full of socks, and nobody is there to stop it. Chaos. Okay, probably not chaos. But a buzzing suitcase could freak out a baggage handler. Or worse, a sniffer dog might think it’s a toy. I’m exaggerating—mostly.
The bigger risk? If the battery decides to have a meltdown. Lithium fires are nasty. That’s why airlines prefer these batteries in the cabin, where staff can fight a fire. In the hold? You’ve got a slow-burning emergency at 35,000 feet. Not ideal.
