China Plug Guide 2025: Types, Sockets & Adapters

Traveling to China? You need to know China electrical system, incl. China plug types, China sockets, China voltage, etc. China uses a 220V power supply and a frequency of 50Hz, with 3 main types of plugs: A, C, and I. These can help to prepare the right adapters. Check details below:

Types of Power Plugs and Sockets in China

China’s electrical system includes several plug types that might be different from what travelers are used to in their home countries. In China, unique power plug types, such as Type A and Type I, are commonly used. Here's a detailed look at the plug types you will encounter in China:

Types of Plugs in China

What do China sockets look like?

A standard Chinese power socket usually has a multi-functional design. There are two holes at the top, which can fit flat pins (Type A) and round pins (Type C). The bottom is a separate grounding slot, specially designed for the three flat pins of Type I plugs. This flexible design means that you may not always need an adapter, but for safety reasons, it's best to carry one with you.

Standard Wall Sockets in China

The standard wall socket in mainland China to be multi-functional. The most common type you see is a single 1 panel that combines 2 different outlet types:

• The Top Opening (Ungrounded): This is a universal slot that can accept both 2 flat-pin (Type A, common in North America and Japan) and 2 round-pin plugs (Type C, common in Europe). You just need to push the pins into the holes.
• The Bottom Opening (Grounded): This is a lock-hole-shaped slot specifically designed for the three flat pins of Type I plugs (used in China, Australia and New Zealand). This grounding method is safer for high-power electrical appliances.

This ingenious hybrid design means that you can plug your device from the United States, Europe or Australia without an adapter. However, since adaptation is not always perfect and sockets may vary, it is always recommended to carry a simple travel adapter to ensure you a safe connection.

What Voltage is Used in China?

China operates on a 220V voltage supply and a frequency of 50Hz. This is consistent across the country, be it in urban or rural areas. In Chinese mainland, 220V, 50HZ, alternating current is generally used (but 220V in Hong Kong and 110V in Taiwan).

Devices with 220V power can work normally in China. However, if your device is configured for a different voltage, such as 110V, which is common in the United States and Japan, you will need a voltage converter or a dual-voltage rated device to use the electronic device safely.

A travel adapter is a small device that lets you to plug electronic products into various types of wall sockets. Since China uses Type A, Type C and Type I sockets, so you may need one unless your plug is a perfect match for these.

China Adapters vs. Converter - How to Choose

• Adapter vs. Converter: This is the most important distinction. An adapter actually just changes the shape of the plug to fit the wall. It won't change the voltage. China uses 220V. So, if your device (such as a hair dryer in the United States) can only operate at 110V voltage, in addition to an adapter, you also need a separate voltage converter; otherwise, you might damage your device.
• Check Your Devices: Most modern electronic products, such as mobile phones, laptops and camera chargers, are "dual-voltage" (look for "Input: 100-240V" on the charger). For these, you only need a plug adapter.

Types of China Adapters & Where to Buy

Before your trip, you can easily purchase an adapter from online retailers such as Amazon, Best Buy or travel stores. Here is a quick table to know where:

How to Use China Adapter Safely

1. Check Voltage: Before plugging in, you must make sure that your device can withstand a 220V voltage.
2. Secure the Connection: Firmly insert the device's charger into the adapter, and then plug the adapter into a wall socket. Make sure there is no water!
3. Use Built-in Safety Features: Choose an adapter with surge protection to prevent power spikes, especially when charging expensive electronic products.

Voltage Converters or Transformers in China

If your device only supports a single voltage (for example, 110V), and you plan to use it in China where the standard voltage is 220V, you will need a voltage converter or transformer. This is so important for high-power appliances such as hair dryers or irons, as they may not support dual-voltage options.

To select the appropriate converter, it is necessary to check the wattage and voltage requirements of the device to ensure compatibility. It is recommended to consult the equipment manufacturer or expert to select the appropriate converter or transformer to ensure the safety and functionality of your equipment in China.

When packing for China, be sure to include these adapters and converters as necessities in your bag to avoid any inconvenience during your stay.

Do I Need a Transformer in China?

It is very important to know whether a transformer is needed in China to safely charge your equipment. Cuz the standard voltage in China is 220V and the frequency is 50Hz, this is different from many other countries and may have risk to equipment that do not fit these specifications.

Charging Laptops in China

For laptops, most modern models are equipped with chargers that support a voltage range of 100V to 240V. This flexibility means that in China, you usually don't need a transformer to charge your laptop. However, it is always wise to check the specifications of your specific charger. If the voltage is within this range, you can use a plug adapter to charge your laptop to suit the local socket type (a, C or I type).

Charging Smartphones in China

Similarly, smartphone chargers are typically designed to accommodate a wide range of voltages, usually from 100V to 240V. Before using the charger in China, please confirm the voltage specification listed on the device. If it says "100-240V", you can charge your smartphone without a transformer. Similarly, you may need a plug adapter to match the type of Chinese socket.

Charging High-Power Appliances

High-power appliances such as hair dryers and curling irons often need more specific voltage settings and may not support dual voltage. These devices usually draw a lot of power (600W to 1200W), and using them with a voltage not suited to their design can be hazardous. If your hair dryer or curling iron is not rated for 220V, you will need a transformer capable of handling a lot much higher power levels—up to 2 to 3 times the device's wattage—to ensure safe operation.

For such high-power appliances, it's good to either bring devices that are rated for international travel (220V compatibility) or consider renting them locally at your destination, such as from a hotel, to avoid the risks and inconveniences associated with using transformers.

How Voltage Differences Affect Devices

Devices are generally designed to operate at a specific voltage and frequency. If a device is plugged into a power supply with a voltage it is not designed for, several problems may occur:

• Lower Voltage: If the power supply voltage is lower than the voltage required by the equipment, it may cause the equipment to operate slowly or not work at all. It may also exhibit unpredictable behavior or simply fail to function.
• Higher Voltage: Connecting the device to a voltage higher than its designed voltage can cause serious damage. The equipment may overheat, posing potential fire hazards or causing permanent damage.

【Precautions and Solutions】

To avoid these problems, travellers should:

• Check the voltage and frequency specifications on the equipment before the trip.
• If their equipment does not match the voltage at the destination, use a voltage converter.
• Consider purchasing general-purpose or dual-voltage equipment for frequent travel.

Global Electrical Standards Overview

Globally, there are three main electrical standards for equipment: 110-120V is mainly used in North America and Central America, 220-240V is commonly used in Europe, Asia and Oceania, and dual-voltage systems. These standards also vary in frequency, either 50 Hertz or 60 Hertz, and include various types of plugs specific to each region. Understanding these differences is crucial for the safe use of electronic devices when traveling internationally.
