A universal plug is often called a “world plug.” This is a type of plug designed to fit into different types of sockets around the world. With a world plug, you can connect your electronic devices to various socket types without needing a specific adapter for each country.

A world plug usually has multiple interchangeable pins or a sliding mechanism that allows you to select the correct configuration for the specific country. This way, you can adapt the plug to the sockets in different countries with various plug types and voltages.

It is convenient to take a universal plug while traveling because then you can safely connect your electronic devices in different countries without worrying about compatibility with local sockets.
