Your toothbrush runs on a lithium-ion battery. So does your laptop, your phone, and that weird gadget your uncle gave you.
Here’s the quirky fact: airlines love lithium-ion batteries in devices. But they hate loose ones. You can’t toss a spare battery in your checked bag. That’s a no-go.
So keep the toothbrush inside your carry-on. It’s the safest spot for your dental drama. The cargo hold gets cold, and your brush might get lonely.
But What About the Brush Head?
This is where it gets fun. The brush head? Completely harmless. You could pack a dozen heads. TSA agents won’t blink.
They care about the motor. That little buzzing beast. It’s technically a “device with a battery.” So treat it like your phone: on the plane, in your bag, and quietly whirring.
One traveler once told me they packed their brush in a sock. Because socks are fashionable and functional. I do the same now. It’s a badge of honor.
