1. the world voltage profile
At present, there are two kinds of voltage used by indoor electricity of all countries in the world, which are 100V ~ 130V, 220 ~ 240V respectively.
100V, 110-130V are classified as low voltage, such as the United States, Japan and shipboard voltage, pay attention to safety;
220 ~ 240V is called high pressure, including 220 V in China and 230 V in Britain and many European countries, pay attention to efficiency.
100V: Japan and Korea,
110 ~ 130V: China Taiwan, the United States, Canada, Mexico, Panama, Cuba, Lebanon and other 30 countries,
220 ~ 230V: China, Hong Kong (200V), Britain, Germany, France, Italy, Australia, India, Singapore, Thailand, the Netherlands, Spain, Greece, Austria, the Philippines, Norway about 120 countries.
