But the shape of the socket is only half the story! Electrical sockets (outlets) in the People's Republic of China usually supply electricity at between 220 and 240 volts AC. If you're plugging in an appliance that was built for 220-240 volt electrical input, or an appliance that is compatible with multiple voltages, then an adapter is all you need. But travel plug adapters do not change the voltage, so the electricity coming through the adapter will still be the same 220-240 volts the socket is supplying. North American sockets supply electricity at between 110 and 120 volts, far lower than in most of the rest of the world. Consequently, North American appliances are generally built for 110-120 volts. But that doesn't mean that your specific appliance isn't already compatible with the higher voltage -- it may very well be.
People's Republic of China Adapters If your appliance is already compatible with 220-240 volt electrical input, one or more of the following travel plug adapters (depending on which type of outlet is installed in any given specific building) will allow you to plug in.
