Saiyue Technology will tell you about the plug standards of various countries. What standard charging plug do you use?

Friends who often travel internationally must know that the rated voltage of each country may be different, and then the standards of the plugs and sockets used are also different. There is no standard power supply voltage and frequency in the world. At present, there are generally two types of voltages used in indoor electricity use in countries around the world, namely 100V~130V and 220V~240V. 100V, 110V~130V are classified as low voltage, such as the voltage used in the United States, Japan and other countries and ships, focusing on safety; 220V~240V is called high voltage, including 220V in China and 230V in the United Kingdom and many European countries , focusing on efficiency. In countries that use 220V~230V, there are also cases where 110V~130V voltage is used, such as Sweden and Russia.

If you plug an electrical appliance that needs to use 220V on a 110V power supply, it may not work or the power will be reduced. And the electrical appliances that need to use 110V voltage may be burned when plugged into the 220V power supply. For the sake of safety, when using electrical appliances, be sure to pay attention to whether the indoor voltage environment matches the electrical appliances.
