Plug and voltage checker

Compares the plug and socket types, the mains voltage and the frequency recorded for two countries, and says whether your plugs fit and whether the voltage differs.

Plug and socket types are written with the International Electrotechnical Commission's letters, A to O. Each country's types, mains voltage and frequency come from the IEC's World Plugs list as it stood in March 2024 (the Internet Archive's copy); the old 110 V and 127 V supplies it still gives for Indonesia and Morocco are left out. For the few territories the IEC does not list, the figures are Wikidata's. Each country links to its record.

Your plugs fit where the destination has a socket that takes them, following the IEC's notes on which plugs fit which sockets. Voltages are compared as the two ranges used around the world, 100–127 V and 220–240 V.

Many countries use more than one socket type, and older buildings often have others; the checker counts a plug as fitting if any socket type in use there takes it, so check which your accommodation has.

Whether a device works on a different voltage depends on the device: check the input rating printed on it or on its charger. Many phone and laptop chargers accept 100–240 V; others need a voltage converter.

Neither source has a record for a few small territories; the checker says so rather than guessing.
