An electric power converter, known as a voltage converter, modifies the voltage of an electrical power source. It could be incorporated into a power supply together with other elements.
The voltage converter is frequently used to create a device that enables appliances designed for a specific location's primary voltage to function in another region with a different voltage. A voltage converter, power converter, travel adapter, etc. are some names for such a device. Most single-phase alternating current outlets around the globe deliver power at 210–240 V or 100–120 V. The voltage can be changed by using a transformer or autotransformer; as (auto)transformers are intrinsically reversible, they can be used to change the voltage in either direction by the same ratio. Electronic circuits can create lighter, more compact devices because it is easier and less expensive to decrease voltage than to increase it. There are small, affordable travel adapters that work with low-power appliances like electric shavers but not, for example, hairdryers; travel adapters typically come with plug-end adapters for the various standards used in multiple countries. For higher power, a transformer would be utilized.

Voltage measurement units
All voltage units are Nanovolts, microvolts, millivolts, kilovolts, megavolts, gigavolts, statvolts, and abvolts.
- Watt is a measure of power; in electrical systems, wattage represents how much energy a gadget uses per second.
- Volts are a unit of measurement for voltage; they stand for the pressure or electrical potential difference.
- Electrical current is measured in amps, or amperes, which show how quickly electricity flows.
- Electrical resistance is measured in ohms; the higher the ohms, the more challenging it is for electricity to flow.
