There are two kinds of power plugs in China, two-pin flat plugs and splayed plugs. There are also two kinds of power plugs in Japan, two-pin flat plug and two-pin flat+round grounding pin.
Among them, the two-pin flat power plug, that is, the double-ended flat-mouth plug, is common in China and Japan; China's three-plug (eight-plug) can't be used in Japan, and it needs a converter to convert it into two-plug.
In addition, the rated voltage in China is 220V and that in Japan is 100V, so the charging speed of electrical appliances in Japan will be slightly slower.
Extended data:
Voltage standards around the world generally conform to the following laws:
1 10- 120V: the United States, Japan and their neighboring countries and regions.
230-240V: Britain and most Commonwealth member countries, most British overseas territories and most Middle Eastern countries.
220-230V: continental European countries and most of their former colonies; Join the countries of the former Soviet Union and those deeply influenced by the Soviet Union.
The United States, Britain and Germany are the first three countries with electricity in the world, and the voltage standards in the world are generally inherited from these three countries, which are generally around 10V (in fact, due to the power supply distance, the voltage in China is about 220V 10V, which does not affect the use).
