How do I convert 120V to 220V?
Use a plug adapter so that you can safely use devices from the U.S., where the standard voltage is 120V, in international destinations such as Europe, the Middle East and Australia, where 220V is standard. Plug adapters also take into account the differently shaped and sized prongs of plugs on electrical devices.
Is it easy to change a outlet to 220V?
Even though the job is relatively easy, it's also very dangerous. Before you replace the electrical outlet, turn off power to your 220-volt outlet circuit at the circuit breaker. Always "lock out" your circuit breaker box to prevent accidental activation of the power switch while you're working on the outlet.
