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.

Based on what's typical for this device — confirm on the label to be sure.

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

Why

The device profile's voltage and plug differ from the destination. Do not plug in with only a plug adapter: it cannot change voltage. A converter and a plug adapter that preserves any required grounding may be an option only after checking your actual INPUT label, load type, startup demand, frequency and both manufacturers' instructions. Wattage alone cannot establish compatibility; the wrong setup can damage the device or cause a fire. The cited Conair manuals describe 120V/60Hz and automatically adjusting 120/240V, 50/60Hz models. Do not broaden those ratings to 100–240V. Check your exact model and any converter prohibition; a plug adapter cannot correct an incompatible electrical supply.

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.

Look for "INPUT 100-240V" on the label. If it shows one voltage only, size any converter from the wattage before buying.
