What's the voltage in Hong Kong?

The voltage in Hong Kong is 220 volts, which is the same as that in Chinese mainland.

Most hotels are equipped with transformers/converters for electrical appliances. Generally, small electrical appliances brought from China can be used.

But the types of plugs are different. The seats in Hong Kong are all British, and the square three-eye right-angle socket is different from that in the mainland. You need to bring your own conversion socket so that the plug in the mainland can be plugged in.

British adapter sockets are available online, so you can search them.

At present, the voltage of household appliances in China is 220 V. At present, there are two kinds of indoor electricity voltages in the world, namely 100 V ~ 130 V and 220 ~ 240 V. 100V,1/kloc-0 ~130V belong to low voltage, such as those in America and Japan. And the voltage on board. Therefore, its equipment is designed according to such a low voltage, and the key point is the security solution of 1. In addition, the Soviet Union's aid has played a very important role in helping our country to carry out economic construction. At that time, China's technical standards for civil electricity were formulated with reference to those of the Soviet Union. Moreover, because the Soviet Union adopted the European AC voltage grade standard of 220V, China's national standard was also set at 220 V, while Japan and South Korea adopted American technical standards after World War II, so their and American civil voltage grade standards were both110 V.

Most of Europe is also 220v, and Japan, the United States and a few European and American countries are110 V. The determination of using voltage depends on the specific national conditions of each country. Due to the low voltage during transmission, the current is large, the energy loss is large and the efficiency is low under the same capacity. But it has little effect on short-distance transportation. It has a great impact on long-distance transportation. Because China has a large land area. Power facilities are relatively backward, especially in remote rural areas and mountainous areas. Therefore, China took this factor into consideration when deciding to use the voltage, and adopted 220V. 1 10V is still safer than 220V.

Because the resistance of Japanese wires is generally lower than that of China wires.
