They should be placed in carry-on luggage
Many electric toothbrushes use lithium batteries due to their long battery life and consistent power output. These batteries have a higher energy density, which allows for longer usage between charges and a lower self-discharge rate, meaning they hold their charge for longer periods when not in use.
However, lithium batteries are considered a higher fire risk, especially if they are damaged, aging, or not properly stored or electrically shielded. This risk is exacerbated when batteries are carried onto airplanes, as a rising battery temperature can cause a thermal runaway when battery heat generation cannot be controlled. Therefore, the Transportation Security Administration (TSA) and the Federal Aviation Administration (FAA) recommend that devices containing lithium batteries be placed in carry-on luggage to ensure they can be monitored in the cabin and to comply with safety regulations.
According to TSA guidelines, electric toothbrushes are allowed in carry-on bags, making it convenient for travellers to maintain their oral hygiene. By placing electric toothbrushes in carry-on luggage, travellers can also avoid potential damage that may occur in checked baggage. Additionally, if you are carrying spare batteries, the TSA and FAA recommend carrying them in your carry-on luggage and protecting them individually to avoid short circuits.
It is important to note that while electric toothbrushes are typically allowed in both carry-on and checked luggage, individual airlines may have specific policies. Therefore, it is recommended to check with your airline before travelling to ensure compliance with their rules.

They have a higher risk of fire hazard
Many electric toothbrushes use lithium batteries due to their long battery life and consistent power output. They are also valued for their ability to hold a charge for longer, making them ideal for those who prefer less frequent charging intervals. However, lithium batteries have a higher risk of fire hazard, especially if they are damaged, aging, or not properly stored or electrically shielded. This poses a significant safety concern, especially on airplanes.
Lithium batteries have a tiny risk of overheating, which can lead to a thermal runaway if the battery heat generation cannot be controlled. This is a serious issue, as demonstrated by the increase in incidents involving lithium battery-instigated fires on airplanes, airports, and cargo facilities. In 2022, the US Federal Aviation Administration (FAA) reported 74 such incidents, a significant rise from the 9 incidents reported in 2014. As a result, the FAA has implemented specific guidelines for traveling with lithium batteries, and most airlines align with these regulations.
To manage the risk, manufacturers have developed advanced detection solutions that use artificial intelligence to automatically identify lithium batteries. These solutions can be used as "add-ons" to existing hold baggage screening equipment. While these technologies are available, the deployment has been slow due to concerns about additional alarms, decreased throughput, and increased costs. Additionally, there is currently no mandate for automated detection in hold baggage or cargo.
To ensure safety and comply with regulations, it is recommended to carry electric toothbrushes containing lithium batteries in carry-on luggage. By keeping them in the cabin, airlines can monitor and manage any potential overheating risks. This also allows for easy access during the flight. It is important to follow the guidelines provided by the TSA and FAA to ensure safe travel with electric toothbrushes and their lithium batteries.
