1. voltage profiles in the world

At present, there are two kinds of voltage used in indoor electricity in the world, which are 100V-130V and 220-240V respectively. 100V, 110-130V are classified as low voltage, such as the United States, Japan, and ship voltage, pay attention to safety; 220-240V is called high voltage, including China's 220 volts and the United Kingdom's 230 volts and many European countries, pay attention to efficiency. In countries where 220-230V voltage is used, 110-130V voltage is also used, such as Sweden and Russia.

100V: 2 countries in Japan and South Korea

110 to 130V: 30 countries such as China, Taiwan, USA, Canada, Mexico, Panama, Cuba and Lebanon.

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.
