The following is a complete overview of the voltage and frequency of all countries in the world and their respective plugs, sockets and household appliances. The table shows that in most countries, the mains voltage is between 220 and 240 volts (50 or 60 Hz); the number of countries operating at 100-127 volts is particularly small. In addition, Type A and Type C are the most commonly used electrical plugs in the world.
In the table below, it can be noted that most countries and regions have clear plug and voltage standards. However, many countries in Latin America, Africa and Asia have different specifications-usually incompatible plugs, and sometimes the voltage varies from region to region. As a result, this makes it difficult for travelers to determine which plug adapters or transformers they need for travel.
