What do you need to use an European hairdryer in USA?

To use a European hairdryer in the USA, you will need a voltage converter. This is because the electrical outlets in the USA supply 120 volts of electricity, while European outlets supply 220-240 volts. A voltage converter will step down the voltage from 220-240 volts to 120 volts, making it safe to use your European hairdryer in the USA.

In addition to a voltage converter, you may also need a plug adapter. This is because the plugs on European appliances are different from the plugs on American appliances. A plug adapter will allow you to plug your European hairdryer into an American electrical outlet.

Once you have a voltage converter and a plug adapter, you should be able to use your European hairdryer in the USA without any problems.
