The electricity in mainland China is generally 220V, 50HZ, AC, while Hong Kong is 220V and Taiwan is 110V.
When travelling in China, a transformer, is necessary. Most of the hotels in China have both 110V and 220V electrical outlets in the bathrooms, though in guest rooms usually only 220V sockets are available.
As the shape of a socket varies between countries, a portable plug adaptor may also be necessary.

- Standards of Sockets
- At present, there are five main standards of sockets in the world, including the standards of Europe, America, Britain, South Africa and China. Hereunder are the related pictures for your reference:
This type of sockets (also called German-standard) is widely used in European countries. Plugs fit very well into such sockets, making it difficult for plugs to work loose by accident, which helps to increase safety.
This is an American-standard socket, which is widely used in the USA, Japan, Canada and other countries.
The British-standard socket is mainly used in Britain, Singapore and many other countries. Hong Kong also uses such a socket.
South African standard
