If you're travelling to China, it's important to know about the different electrical sockets and voltages used in the country. China has three associated plug types: Type A, Type C, and Type I. The standard voltage in China is 220V at a frequency of 50Hz, so you may need a power converter or transformer if the appliance is single voltage rated. It is always worth doing some research before your trip to ensure you have the correct travel adapter and to avoid having to purchase new appliances.

What You'll Learn

China's power voltage is 220V, 50Hz AC
In China, there are three main types of power plugs and sockets (outlets): Type A, Type C, and Type I. The type of socket or plug you need will depend on the appliance you are using. Type A sockets are the most common in China and are two-pronged with round holes. Type C sockets are also common and are designed for plugs with two round pins. Type I sockets are the most common type of high-power electrical socket in China and have three flat pins in a triangular layout.
If you are travelling to China, it is important to research the types of sockets and plugs used there to ensure you bring the correct travel adapter. You can purchase travel adapters before your trip or in China upon arrival. Many modern devices, such as smartphones and tablets, can also be charged via USB cables, and these ports are commonly available in public places in China. Power banks are another versatile and mobile charging solution that can be purchased online or at electronics stores.

Type A, C, and I sockets are used
If you are travelling to China, it is important to research the types of sockets used to avoid the inconvenience of not being able to charge your devices or use other appliances. You may need to purchase a travel adapter, and it is worth noting that some travel adapters are not suitable for appliances that require an earth connection. It is also important to check the voltage of your appliances. While chargers for phones, tablets, and cameras often function normally within a wide power voltage range, other appliances such as hair dryers may require a voltage converter or transformer.
Voltage converters and transformers perform similar functions but differ in application. Converters are typically used with appliances that operate for a short duration, while transformers can be used with appliances that operate continuously. Most voltage converters and transformers come with plug adapters, but it is important to check the maximum power rating to ensure your appliance does not exceed it.
To use a travel adapter, plug your device's charger into the adapter and then plug the adapter into the wall socket. Ensure any switch on the adapter is set correctly if it includes voltage conversion options. Always check that your device is compatible with the voltage supplied by the outlet, especially if using a simple adapter without conversion capabilities.

Type A sockets are the most common
Type A sockets are one of the three main types of sockets used in China, the other two being Type C and Type I. The standard voltage in China is 220V at a frequency of 50Hz, and this information is important for travellers to China to know in advance to avoid having to purchase adapters or new appliances.
The power voltage in China is 220V 50Hz AC, and the standard socket/plug is also common in Australia and New Zealand. The upper part of the socket usually accommodates two flat pins or two round pins, which are common for Type A and Type C plugs, respectively. The lower part of the socket includes an earthed configuration with three flat pins in a triangular layout, designed for Type I plugs.
Type A sockets are widely used in Mainland China, and it is important to understand the role and functionality of travel adapters when preparing for travel to China. Chargers for most electronic devices like cell phones, tablets, and cameras can function normally in the wide power voltage of 110~240V. However, for other electrical appliances such as hair dryers or curling irons, it is necessary to check the voltage and ensure compatibility with the power in China.

Type I sockets are the most common for high-power appliances
In China, there are three main types of power sockets: Type A, Type C, and Type I. Type I sockets are the most common for high-power appliances. They are designed with an earthed configuration, featuring three flat pins in a triangular layout. This setup ensures safe and versatile usage across numerous electronic devices, ranging from smartphones to kitchen appliances.
Type I sockets are commonly used in extension cords in China and are also the standard in Australia and New Zealand. The standard voltage in China is 220V, with a frequency of 50Hz, and this applies to all three types of sockets.
It is important to note that the shape of sockets and voltage can vary between countries. As a result, travellers to China often require a portable plug adaptor. These can be purchased online or from electronics stores in one's home country or upon arrival in China.
When preparing for a trip to China, it is essential to research and understand the role of travel adapters. This includes checking the compatibility of one's devices with the power supply in China and ensuring that the correct adapters are obtained. By taking these precautions, travellers can ensure their electronic devices are functional during their stay in China.
Furthermore, it is worth mentioning that chargers for most modern devices, such as smartphones and tablets, can typically operate within a wide power voltage range of 110V to 240V. Therefore, these devices can generally be used without the need for a voltage converter or adapter in China, as long as the correct plug type is available for the sockets.

You may need a travel adapter or voltage converter
When travelling to China, it is important to understand the local electrical system, including the types of sockets, plugs, and voltage. China uses three main types of plugs and sockets: Type A, Type C, and Type I. Type A sockets are the most common in China, featuring two-pronged, round-holed plugs, which are typically used in North America, Europe, and Australia. Type C sockets, on the other hand, accommodate two-pronged, round pins, commonly found in European countries. Lastly, Type I sockets are the most prevalent for high-power electrical devices in China, featuring three flat pins in a triangular layout for earthed connections.
The standard voltage in China is 220V at a frequency of 50Hz, which is different from many other countries. Therefore, you may need to use a voltage converter or transformer for your electrical appliances to work safely and properly. Voltage converters ensure that your devices operate at the same voltage as the power supply in China. Most converters come with plug adaptors, so you may not need a separate travel adapter. However, it is crucial to ensure that your devices do not exceed the maximum power rating of the converter.
To use a travel adapter, you simply plug your device's charger into the adapter and then connect the adapter to the wall socket in China. It is important to check that your adapter has the correct settings and is compatible with both the plug types used in China and your device's power requirements. Many adapters offer built-in protections against overcurrent and short circuits, which are essential for safeguarding your devices.
If you are unable to find a suitable travel adapter or converter, there are alternative options for charging your devices. USB charging ports are commonly available in public places such as airports, cafes, and on public transport in China. These USB ports can be found integrated into seating areas or digital kiosks. Additionally, power banks are widely available for purchase at electronics stores or online platforms within China, offering a versatile and mobile charging solution.
