Voltage and frequency by country
Most of the world uses a mains supply of 220 to 240 volts, while North America, much of Central America, Japan and a few other places use 100 to 127 volts. Frequency is 50 or 60 hertz. This page groups 187 countries by the nominal voltage and frequency that two independent sources agree on. Figures are nominal; the real supply varies a little. Data checked 2026-10-27.

Frequently asked questions
Which countries use 110 volts?
Countries with a nominal supply of 100 to 127 V include Bahamas, Barbados, Belize, Canada, Colombia, Costa Rica, Cuba and Dominican Republic and others listed above. Many are in North and Central America.
Will my charger work abroad?
Most modern phone and laptop chargers accept 100 to 240 V and 50 or 60 Hz, so they work worldwide with only a plug adapter. Check the small print on the charger. Single-voltage appliances such as hair dryers may need a converter.
What is the difference between 50 Hz and 60 Hz?
It is how many times per second the alternating current changes direction. Modern electronics usually cope with both, but some clocks, motors and older equipment do not.
