Electric shavers do not have to go in hand luggage, but in 2026, it is highly recommended that you carry them there. Under FAA and EASA safety guidelines, any device containing a lithium-ion battery is safer in the cabin where any rare thermal event (smoke or fire) can be immediately addressed by the crew. While a shaver with an internal battery is technically permitted in checked bags, spare (uninstalled) lithium batteries are strictly prohibited in the cargo hold and must be in your carry-on. From a practical standpoint, keeping your shaver in your hand luggage prevents it from being lost if your checked bag is delayed and protects it from the rough handling of airport baggage systems. Most modern shavers are also "travel-safe" with a lock feature to prevent them from accidentally turning on mid-flight, but if yours doesn't have one, consider removing the battery or head before packing it.
