Consider the voltage. The second consideration is voltage, or the pressure under which current flows through an electrical system. While most U.S. appliances work at 110 volts, many foreign power companies generate electricity at 220 volts. Some appliances have a toggle switch that allows them to work with both voltages, but for non-dual voltage appliances, you'll need a converter to step down the 220 electric current to 110 so your appliances won't burn out.
When appliances from 110 volt countries need to be used in 220 volt countries, a âStep-Downâ voltage converter is needed. When appliances from 220 volt countries need to be used in 110 volt countries, a âStep-Upâ voltage converter is needed. For More Information See Our... Voltage Converter Buying Guide.
