Such as Japan, the United States, Canada and so on are all low voltage of 11V V. \ r \ n \ r \ nAt present, there are two types of indoor electricity used in the world, which are 1 V ~ 13 V and 22 ~ 24 V respectively. 1V, 11 ~ 13 V are classified as low voltages such as those in the United States, Japan, etc. and ships, because its equipment is designed according to such low voltages, with emphasis on safety; 22 ~ 24 V is called high voltage, which includes 22 V in China, 23 V in Britain and many European countries.

Ordinary electrical appliances belonging to the same voltage system are taken abroad for use, and the voltage is generally not a problem, because most electrical appliances have a voltage floating range of 2%, such as electric furnaces and rice cookers, because even in China, the highest voltage can sometimes reach 25 volts, so the voltage of 23 volts only makes them heat up faster, and there is not much problem.
