China: Plugs, Voltage & Frequency
Type A/I · 220 V · 50 Hz
China uses Type A, Type I plugs and runs on 220 volts at 50 Hz. This guide covers what the sockets look like and exactly what you need to power your devices there.
Plug Types in China
- Type A — Type A is the flat, two-blade North American plug. The blades are parallel and unpolarized, with no ground pin.
- Type I — Type I has two (or three) flat angled blades in a triangular layout, used in Australia, China, and Argentina.
Voltage and Frequency
China operates on 220 V at 50 Hz. Wall outlets deliver this as standard mains power. USB chargers and most modern electronics accept a wide input range, but always check the rating printed on your device.
Traveler Note: Adapter or Converter?
You need a Type A plug adapter to fit China's sockets. Because China supplies 220 V, appliances built for 100-120 V need a step-up voltage converter unless they are dual-voltage 100-240 V, which most phone and laptop chargers are.
Mainland China uses Type I; Type A plugs are often accepted in hotels.
Frequently Asked Questions
Do I need a voltage converter or just an adapter for China?
You need a Type A plug adapter for China's sockets. A voltage converter is only required for devices that are not dual-voltage: China runs on 220 V at 50 Hz, so single-voltage 100-120 V appliances need a step-up converter and 220-240 V appliances need a step-down converter. Most phone and laptop chargers are 100-240 V and need only the adapter.
What plug type does China use?
China uses Type A, Type I. You may encounter more than one type in hotels and older buildings.
Can I charge my phone or laptop in China?
Almost certainly. Phone and laptop chargers are normally rated 100-240 V and only need a Type A plug adapter, not a voltage converter. Check the INPUT line on the charger to confirm.
