What are the voltage frequency and power plug specifications in the world?

Currently, there are two main types of indoor voltages used in various countries: 100V–130V and 220V–240V. The 100V and 110V–130V range is classified as low voltage, used in countries like the USA and Japan, as well as on ships, with a focus on safety. The 220V–240V range is classified as high voltage, including China's 220V and the UK's 230V, along with many European countries, emphasizing efficiency. Some countries that primarily use 220V–230V also have instances of 110V–130V usage, such as Sweden and Russia.

100V: Japan, South Korea.

110V–130V: Taiwan, USA, Canada, Mexico, Panama, Cuba, Lebanon, and about 30 other countries.

220V–230V: China, Hong Kong (200V), UK, Germany, France, Italy, Australia, India, Singapore, Thailand, Netherlands, Spain, Greece, Austria, Philippines, Norway, and around 120 other countries.
