The voltage situation in the world shows that there are two kinds of voltage used in the world, which are 100V to 130V and two types from 220 to 240V, respectively. 100V, 110 ~ 130V are classified as low voltage, such as the United States, Japan and so on, and the voltage on board pays attention to safety. 220 to 240V is called high voltage, which includes 220 volts in China and 230 volts in Britain, and many European countries pay attention to efficiency. In countries with 220 to 230V voltage, there are also 110 to 130V voltages, such as Sweden and Russia. 100V: Japan, South Korea 2 in 110 ~ 130V China: Taiwan, United States, Canada, Mexico, Panama, Cuba, Lebanon and other 30 countries from 220 to 230V (200V): China, Hongkong, Britain, Germany, France, Italy, Australia, India, Singapore, Thailand, Holland, Spain, Greece, Austria, Philippines in Norway, about 120
