Electric toothbrushes with lithium-ion batteries
Electric toothbrushes are permitted in carry-on luggage, according to the Transportation Security Administration (TSA) and the Federal Aviation Administration (FAA). However, it is essential to note that these devices contain lithium-ion batteries, which are subject to specific regulations due to safety concerns.
Lithium-ion batteries, widely used in electric toothbrushes for their higher energy density and longer lifespan, pose a potential fire hazard risk, especially if damaged, ageing, or improperly stored. To mitigate this risk, the TSA and FAA have implemented guidelines for carry-on luggage. Passengers are advised to place their electric toothbrushes in carry-on bags, ensuring easy accessibility during security checks and compliance with safety regulations. It is also crucial to switch off the device completely and, if available, utilise the travel lock feature to prevent accidental activation during the flight.
When packing an electric toothbrush, it is recommended to use the provided travel case, which protects the brush and prevents unintended activation. Alternatively, removing the lithium-ion battery and packing it separately can be considered. Labelling the battery with its type and capacity aids in quick identification during security checks and ensures proper handling. Passengers should also be mindful of battery capacity restrictions. Batteries with a capacity of up to 100 watt-hours (Wh) are typically allowed without approval, while those between 100Wh and 160Wh may require airline permission. Batteries exceeding 160Wh are generally prohibited on passenger aircraft.
While electric toothbrushes are allowed in carry-on luggage, it's important to familiarise yourself with the specific guidelines provided by the TSA and FAA. These regulations are in place to ensure the safety of all passengers and must be adhered to when travelling with lithium-ion battery-powered devices.

Battery capacity restrictions
Electric toothbrushes are allowed in carry-on luggage, but there are battery capacity restrictions to be aware of. These restrictions apply to lithium-ion and lithium metal batteries, which are commonly found in electric toothbrushes and other electronic devices.
The specific restrictions on battery capacity depend on whether the battery is installed in a device or is a spare (uninstalled) battery. For batteries that are installed in a device, there is no explicit capacity limit mentioned in the sources. However, it is important to ensure that the battery is properly secured and protected from damage, short circuits, and accidental activation during the flight.
For spare (uninstalled) batteries, the restrictions are as follows:
- Batteries with a capacity of up to 100 watt-hours (Wh) are typically allowed in carry-on luggage without approval.
- Batteries between 100Wh and 160Wh may require airline approval and there may be a limit of up to two spare batteries per person in this size range.
- Batteries exceeding 160Wh are usually not permitted on passenger aircraft.
It is important to note that these restrictions may vary slightly depending on the airline and specific regulations in your region. It is always a good idea to check with your airline and consult the latest guidelines from the Transportation Security Administration (TSA) and the Federal Aviation Administration (FAA) before packing your electric toothbrush and any spare batteries.

Packing tips
If you're planning to bring your electric toothbrush on a trip, there are a few things to keep in mind to ensure you're following the rules and keeping your toothbrush safe.
First, check the type of battery your toothbrush uses. Most electric toothbrushes use lithium-ion batteries, which, according to TSA guidelines, should be placed in carry-on luggage. This is because lithium batteries, if damaged, could potentially overheat and pose a safety issue. If your toothbrush uses AA alkaline batteries, you have the option to pack it in your carry-on or checked luggage.
Make sure your toothbrush is fully charged before you leave, and consider bringing a charger with you. If you do bring a charger, pack it separately from your toothbrush, and make sure it's easily accessible.
When packing your electric toothbrush, it's a good idea to put it in a travel case to protect it and prevent accidental activation. If your toothbrush doesn't have a travel case, you can remove the battery and pack it separately. It's also recommended to put your toothbrush in a sealable bag to protect it from getting dirty or wet during your trip. You can also pack some toothpaste and floss in the bag so you have everything you need to brush your teeth while you're away.
Keep in mind that some airlines may have more stringent restrictions on carrying luggage with lithium batteries, so it's always a good idea to check with your airline before your flight.

Electric toothbrushes with alkaline batteries
Electric toothbrushes are allowed on planes, but there are some rules and restrictions to be aware of. The Transportation Security Administration (TSA) states that devices containing lithium metal or lithium-ion batteries should be placed in carry-on bags. This is because these batteries, if damaged, could potentially overheat and pose a safety issue.
If your electric toothbrush uses alkaline batteries, such as certain Spinbrush™ models, you have the option to pack it in your carry-on or checked luggage. Alkaline batteries are safe and have high energy density, a long lifespan, and are almost always recyclable.
It is important to note that electric toothbrushes or any other battery-powered devices may be considered hazardous materials under national aviation regulations, so some restrictions apply.

Always carry it as part of your hand luggage and pack it in a way that will not cause any potential damage during transit.
To ensure compliance with airline and airport security regulations, it is recommended to keep your electric toothbrush easily accessible for airport security checks. Many electric toothbrushes come with a travel case that protects the brush and prevents accidental activation. If your toothbrush does not have a travel case, consider removing the battery and packing it separately. Additionally, make sure your toothbrush is completely switched off before packing it.
When travelling with an electric toothbrush, it is advisable to fully charge the device before your trip. This will save you the trouble of finding an outlet to charge it during your journey. If needed, pack your charger separately in a place where it can be easily accessed, such as your carry-on bag.
