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.
Power Converters and Transformers. If youâre traveling with certain devices, such as older hair dryers and irons, you may also need a voltage converter or transformer. The world runs on two types of electricity: 110/125V or 220/240V. North American devices run on 110/125V electricity while the majority of the world runs on 220/240V.
