Can I Use My Hair Straightener (Flat Iron) in South Korea?

Q: What plug type does South Korea use?

South Korea uses Type C/F sockets at 220V / 60Hz.

Your hair straightener (flat iron) needs a converter and an adapter in South Korea.

Adapter + voltage converter needed

Two things differ here: the voltage and the plug shape. You need both a voltage converter (transformer) rated above your device's wattage and a plug adapter to fit local sockets. Do not plug in with only a plug adapter — an adapter does not change voltage, and the wrong voltage can damage your device or cause a fire.

Why

A US 120V single-voltage straightener on 230V power overheats and can scorch hair or fail. Confirm "100–240V" on the plate, or carry a dual-voltage travel model. Frequency does not affect heating.

South Korea runs 220⁠V / 60⁠Hz. South Korea runs 220V at 60Hz with European-style Type C/F sockets, which often surprises US visitors. US single-voltage devices need a converter.
