Chinese power outlet
Three different types of electrical outlets are found in China. There are Type A sockets, which have two flat holes and are used in the U.S., and Type C sockets, which have two round holes and are common in Europe.
The third outlet type which is also the most common in China is type I, which is the only one that’s grounded. It has three flat holes, with the top two positioned at a diagonal.
Unlike the US, China uses a frequency of 50 Hz and a voltage of 220V. While the majority of other countries operate at 230V, anything between 220V and 240V is fully compatible.
All of this information refers to mainland China, but note that electricity is different in the country’s two Special Administrative Regions and in Taiwan. Hong Kong uses Type G outlets, the British outlet type with three rectangular holes. Some Type D sockets, normally used in India, are found in Hong Kong as well. In Macau, you might encounter any of four different kinds: Type D, Type G, Type M (a larger version of Type D, which is mainly used in South Africa), and Type F (which has two round holes and two grounding clips and is found throughout Europe). In Taiwan, you’ll find Type A and Type B sockets, the two types used in the U.S. Hong Kong, Macau, and Taiwan all use the same 50 Hz frequency as mainland China. However, while Hong Kong and Macau also have the same voltage of 220V, Taiwan uses 110V.
