As a reliable AC DC power adapter manufacturer in China, we are professional in making Chinese/CN wall power adapters with 12 years' R&D innovation capability. We produce the type of Chinese national standard wall outlet and plug power adapters (CCC)which have 2 flat pins without small holes.
We have the 100% high voltage test,100% aging test and 100% full inspection for our industrial power adapters. Our Chinese/CN power adapter types are comprehensive: wall mount power adapters, interchangeable power plug adapters and desktop power adapters.
Different from the plug type for South Korea power adapter, in China, there are three associated plug types for CN power adapters, types A, C and I. Plug type A of Chinese/CN wall power adapters is the plug which has 2 flat parallel pins, plug type C of Chinese/CN wall power adapters is the plug which has 2 round pins, and plug type I for Chinese/CN wall charging power adapters is the plug which has 3 flat pins in a triangular pattern.
The standard voltage for CN/Chinese wall plug and outlet adapter power supply is 230 V and the standard frequency is 50 Hz. Small print on the device or power adapter indicates what voltages the device can work with. If you see 100-240V 50/60Hz printed on the CN/Chinese wall plug and outlet power adapters, the power adapter is rated to work on all voltages used worldwide.
China runs a voltage of 220 V with a standard frequency of 50 Hz. You cannot use your electric appliances in China without a voltage converter, because the standard voltage in China (220 V) is higher than the voltage (100V) for Japan power adapters and the voltage in the United States of America (120 V)
China has three types of the plug of CN/Chinese wall charging power adapters. The most common type of plug is similar to an American two-pronged plug, but the Chinese plug for charging power adapters has shorter prongs without the holes found in American plugs, so you'll still need to use an adapter because the American plugs will be too large for the sockets.
