Yes, you can bring an electric razor on a plane in both your carry-on bag and your checked luggage. The TSA and international aviation authorities (like EASA) do not classify electric razors as dangerous "sharp objects" because the blades are housed behind a protective foil or guard, making them incapable of being used as a weapon. If the razor contains a built-in lithium-ion battery, it is actually preferable to keep it in your carry-on, as lithium batteries are safer in the pressurized, monitored cabin than in the cargo hold where an undetected fire could occur. If you are packing it in a checked bag, you should ensure the razor is turned off and the power button is protected to prevent it from accidentally activating during transit—a vibrating suitcase can often cause a security alert. For international travel in 2026, remember that while the razor itself is allowed, you may need a plug adapter or a voltage converter to charge it in your destination country, although many modern electric razors are dual-voltage and can handle 110V to 240V systems automatically.
