Where to pack an electric toothbrush when flying?
When flying, electric toothbrushes must be packed in carry-on luggage if they contain lithium-ion batteries, as per international aviation regulations. Devices with non-removable lithium batteries (common in modern electric toothbrushes) cannot be checked due to fire risks. Dry battery-powered models may be checked or carried on. Always confirm battery type and capacity (≤100Wh for lithium batteries) and secure the power switch to prevent accidental activation during transit.

Why can’t lithium-powered electric toothbrushes be checked in?
Lithium batteries pose fire risks in cargo holds where fires can’t be quickly contained. Aviation authorities globally mandate carrying them in cabin luggage for immediate response if thermal issues occur. Pro Tip: Wrap toothbrush heads in sealed bags to prevent accidental activation during security checks.
Lithium-ion batteries in electric toothbrushes typically range from 2-10Wh, well below the 100Wh limit for carry-ons. However, their chemistry remains regulated due to thermal runaway potential. For example, a 5Wh battery contains enough energy to sustain a fire if damaged. Transitionally, while these risks are low, standardized precautions apply across all lithium-powered devices. Always check for airline-specific rules—some carriers like Qatar Airways require battery removal demonstrations upon request.
How should I prepare my electric toothbrush for airport security?
Place it in accessible outer pockets of carry-ons for quick inspection. Security may require separate scanning of devices with embedded batteries. Warning: Activated vibration modes during screening could delay clearance.
Use travel cases with power-lock features to prevent accidental activation. For instance, Philips Sonicare models have travel mode that disables buttons. Practically speaking, remove detachable brush heads and store them separately to avoid moisture-related issues during pressure changes. Transitionally, consider placing the toothbrush in clear plastic bags alongside other electronics for streamlined screening. Pro Tip: Carry manufacturer documentation showing battery specifications to resolve potential disputes.
| Battery Type | Carry-On | Checked |
|---|---|---|
| Lithium-ion (built-in) | Allowed | Prohibited |
| Dry cell (removable) | Allowed | Allowed |
| NiMH (rechargeable) | Allowed* | Allowed* |

FAQs
Yes, but each lithium battery must stay below 100Wh. Most toothbrushes comply, but declare quantities exceeding 15 personal devices per IATA guidelines.
Do wireless charging cases count toward battery limits?
Yes—combine the case’s battery capacity with the toothbrush’s. If total exceeds 100Wh, seek airline approval 72 hours before departure.
