Electric shavers have different plugs for safety reasons. In the UK and Europe, mains voltage is 230V, which can be lethal when mixed with water. Shaver sockets, also known as razor outlets, have a low voltage output of 115-230V, reducing the risk of electric shock. These sockets have two round pins and are designed to fit shaver plugs, which also have two pins, making them easy to connect. Shaver sockets are commonly installed in bathrooms and hotels to accommodate electric razors and toothbrushes.

Electric shock safety
The safety features of "shavers only" outlets are further enhanced by their unique plug design. These outlets usually have two round prongs or pins, commonly known as Euro-style plugs in the UK and some other countries, while others use American flat-prong plugs or local variations. The two-pin design ensures that the output circuits are electrically isolated from the incoming supply. This isolation means that even if you come into contact with a conductor, such as a cut in the flex, you won't receive an electric shock as there is no current path to the earth.
It's important to note that the limited power output of these outlets is not primarily for bathroom safety but rather due to the small transformer required to fit within the constraints of the back box. Additionally, the absence of an earth pin in the two-pin design further emphasizes the safety focus of these outlets.
While "shavers only" outlets are a step towards safer bathroom electrical usage, it's worth mentioning that they are not the only solution. In some countries, such as the UK, regulations allow for conventional sockets in bathrooms as long as they are at least 3 meters away from a bath or shower. However, due to space limitations in most bathrooms, the two-pin "shavers only" outlets have become the more popular and practical option for electric shavers and toothbrushes.
To ensure safety, it is recommended to use the appropriate plug adapters when using electric shavers and toothbrushes. While some devices may come with two-pin plugs, not all bathrooms are equipped with the corresponding sockets. Adapters are readily available at affordable prices, ensuring safe and convenient charging solutions for personal grooming devices.

Two-pin plugs
The use of two-pin plugs for electric shavers also ensures compatibility with shaving mirrors, which often have built-in sockets. However, some users have expressed frustration over the need to purchase separate adapters to use their devices with standard three-pin sockets. This is because UK building regulations prohibit the installation of three-point plugs in bathrooms, as the high voltage of 240V can be lethal when combined with water.
The two-pin plugs used for electric shavers and toothbrushes are typically designed to fit into specific shaver sockets, which provide a reduced voltage output compared to standard sockets. This is a safety feature to prevent electric shocks, particularly in bathrooms where the risk of water exposure is higher.
While two-pin plugs are commonly used for electric shavers, some models may come with three-pin plugs and adapters. It is important to follow the instructions provided with the device to ensure safe and proper use.
In summary, the use of two-pin plugs for electric shavers and their associated sockets is a safety measure designed to reduce the risk of electric shocks, particularly in bathrooms where water exposure is a concern.

Voltage output
Electric shavers have different plugs because they have a low-voltage output, usually around 115-230 volts. This reduced voltage ensures the safety of users when operating electric shavers and toothbrushes near water sources. In the UK and Europe, mains voltage is 230V (plus or minus a bit) referenced to earth. It only takes a fraction of this to kill you (3mA), so it is very unsafe to have anywhere near a bathroom where wet hands massively increase the risk of electric shock.
Shaver sockets contain a transformer that isolates the mains supply from the earth. The voltage is the same, or 115V for the centre-tapped output. If you touch one of the two output pins, you won't get a shock because you're connected to the ground, but the output side of the transformer isn't. This is why shaver sockets have two pins instead of three.
Shaver sockets are ideal for charging electric shavers and toothbrushes, providing the appropriate voltage for these devices. They are commonly installed in bathrooms in hotels to accommodate guests' personal grooming needs. However, it's important to note that shaver sockets are not designed for continuous use and may stop working if used for extended periods.
In terms of compatibility, shaver sockets are tailored to accommodate shaver plugs, which are typically used with electric razors and toothbrushes. These plugs have two round pins that fit perfectly into the shaver socket. If you need to use a different plug type, you can purchase adapters to use with your electric shaver. These adapters are usually inexpensive and readily available.

Plug compatibility
The two-pin plug on electric shavers may not fit into a regular UK three-pin socket, so an adapter is often required. These adapters are readily available and can be purchased for a low cost from various retailers, including Argos, Tesco, and eBay.
In Europe, electric shavers may have a different plug type, known as the Europlug or the European socket. This type of plug has two round pins and a grounding clip, ensuring a safe connection to the electrical system. European sockets are highly versatile and can accommodate a wide range of electrical plugs used in different countries.
When travelling with an electric shaver, it is important to consider the voltage requirements of your destination. If you are travelling to a country with a different voltage, you will need to use a plug adapter suitable for that country.
Additionally, some electric shavers may have compact power supplies, and it is crucial to ensure that the wires carry only low voltage to avoid blowing up the appliance or causing electrical hazards.

Plug adapters
In the UK, electric shavers often come with a 2-pin plug, which can be plugged into a "shavers only" socket in the bathroom. These sockets are designed to reduce the risk of electric shock, as they severely restrict power output. However, many bathrooms in the UK do not have these 2-pin sockets, so it is necessary to purchase a plug adapter to use electric shavers. These adapters are usually inexpensive and can be found at local stores or online.
It is important to note that some plugs are actually compact power supplies, and their wires carry only low voltage. Connecting these wires to the live and neutral wires of a simple plug could be dangerous. Therefore, it is crucial to carefully check the plug before using an adapter.
Additionally, multi-country or region plug adapters offer enhanced versatility for travellers visiting multiple destinations. These adapters allow users to plug in multiple devices simultaneously or pair them with multi-socket extension leads to accommodate higher power demands.

Electric shavers have different plugs for safety reasons. In the UK and Europe, mains voltage is 230V, which can be lethal when mixed with water. Shaver plugs have two round pins that fit into a "shavers only" socket, which has a low power output. This design electrically isolates the output circuits from the incoming supply, so if you touch a conductor with a wet hand, you won't get electrocuted.
A "shavers only" socket is a special low-power outlet for bathroom use. They are designed to accommodate shaver plugs, which are commonly used with electric razors and toothbrushes. These sockets have a reduced voltage output, usually around 115-230 volts, to ensure user safety.
Standard plug sockets have three pins and are not allowed in bathrooms in the UK due to safety concerns. Shaver sockets with two-pin plugs are mandatory for all bathroom appliances.
If you don't have a "shavers only" socket in your bathroom, you can purchase a plug adapter to use your electric shaver. These adapters are typically inexpensive and can be found at most pound shops or on eBay for around £1-£5.
