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. This table shows that in most countries, the main power supply voltage is between 220 to 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 use electrical plugs worldwide.
In the table below, it can be note 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 by region. Therefore, this makes it difficult for travelers to determine the plug adapters or transformers they need for their travels.
