China Power Plugs and Voltage

Mainland China commonly uses a 220-volt, 50-hertz electricity supply. A plug adapter changes the physical connection; it does not change voltage. Whether you need only an adapter or also a voltage converter depends on the input rating printed on each device.

Read the device label

Look for text such as:

Input: 100–240V, 50/60Hz

A device with that range is generally designed for both common voltage systems and usually needs only the correct plug adapter. Phone, tablet, laptop, and camera chargers are often dual-voltage, but check each one.

A label such as 120V 60Hz is not dual-voltage. Plugging it into a 220V supply without a suitable converter can damage the appliance or create a safety risk.

Adapter or converter?

• Travel adapter: changes the pin shape so a compatible device can connect.
• Voltage converter or transformer: changes the electrical voltage for a device that cannot accept the local supply.

Converters must be rated for the appliance's continuous and startup power. Hair dryers, straighteners, kettles, heating tools, and other high-wattage devices are the most common problem. A small electronics converter may be unsafe for them. Using the hotel's appliance is often the better choice.

Plug shapes

You may encounter flat two-pin outlets, three-pin angled outlets, and sockets that accept more than one plug type. Availability varies by building and hotel. Do not assume that a “universal” hotel socket will securely hold every plug.

Bring a reputable adapter with the safety certification appropriate to where it was sold. Loose, sparking, cracked, or unusually hot equipment should be unplugged.

USB charging

Hotels, trains, airports, and cafés may offer USB-A, USB-C, or multi-standard sockets, but power output varies. Bring your own trusted charger and cable. A USB port that fits the plug may still charge slowly or fail to support a laptop.

For public charging, consider data security. A power-only adapter or your own wall charger avoids connecting the phone's data pins to an unknown USB system.

Practical packing list

• one certified adapter compatible with your plugs;
• a dual-voltage multi-port charger;
• required USB-C or other cables;
• a compact power bank compliant with current airline and rail rules;
• no high-wattage appliance unless its voltage and converter requirements are fully understood.

Check airline and China Railway restrictions before carrying a power bank. Capacity labeling and transport rules can change and are separate from wall-voltage compatibility.

Safety

Do not stack multiple loose adapters or overload a hotel outlet. Keep power equipment away from water. Stop using anything that becomes excessively hot or smells damaged. Ask the accommodation before connecting medical or other essential equipment.
