Traveling has become increasingly complicated. What used to be simple now requires paying attention to the most unexpected items. Even something as everyday as an electric toothbrush can cause you problems if you don't follow TSA rules.
The hidden risk of lithium batteries
Electric toothbrushes usually run on rechargeable lithium batteries. Not all of them are dangerous, but these batteries can overheat or cause short circuits. TSA has stepped up inspections because there are more and more incidents on planes.
This isn't paranoia; just in the first few months of 2025, the FAA reported dozens of in-flight incidents related to batteries. Some flights had to land early as a precaution. That's why any device with a rechargeable battery is under scrutiny.
How to transport your toothbrush without issues
The main rule is clear: anything with a lithium battery must travel in your carry-on luggage. Never check it. If something goes wrong, the crew can act quickly, and your suitcase isn't there to help.
If your toothbrush runs on regular batteries, there's no problem. But if it charges with a base or USB, it's safest to put it in your carry-on bag. In addition, some travelers cover the brush head or secure it with a case to prevent it from turning on accidentally during the flight.
Other devices under scrutiny
The electric toothbrush isn't alone on TSA's list of inspected items. Other devices also draw attention:
- Cordless irons and curling irons
- Airbrush makeup devices
- LED masks
- Electronic massagers
- Devices that run on butane gas
They all have something in common: lithium batteries or fuel. On a plane, these items require special control. Even the smallest objects can become a risk if they're not handled properly.
Practical tips for safe travel
To avoid problems and surprise fines:
- Carry your electric toothbrush in your carry-on luggage.
- Make sure it's turned off before going through security.
- Protect it with a case or cap to prevent accidental activation.
- If you don't know what kind of battery it has, follow the TSA rule: "When in doubt, leave it out."
Checking your toiletry bag before flying may seem like a minor detail, but it can save you from bigger problems. A poorly placed toothbrush can be enough for you to go through an extra inspection or even face a fine.
Traveling today means paying attention to the small details. A smooth flight starts with checking what you put in your carry-on. Don't underestimate your electric toothbrush: it can cause you more than one scare at the airport.
