Korea uses 220V at 60Hz with European-style round two-pin plugs (Type C and Type F). Travelers from the US, UK, Japan and most of Asia need a plug adapter; most modern electronics handle 220V without a voltage converter.
Check your charger for "100–240V" — if printed, you only need a cheap plug adapter, sold at any convenience store or Daiso for ₩2,000–5,000.

Where can I buy a plug adapter for Korea after I arrive?
Incheon and Gimpo airports sell Type C/F adapters at convenience stores (CU, GS25) and Daiso for roughly ₩3,000–₩8,000. You'll also find them at Olive Young and electronics shops in Myeongdong, but buying one before you fly is cheaper and avoids the airport markup.
Do I need a voltage converter for my hair dryer or curling iron in Korea?
Yes, single-voltage 110V hair tools from the US or Japan will burn out on Korea's 220V even with an adapter. Either buy a dual-voltage travel appliance or use the hair dryer provided in most Korean hotels and guesthouses, which is already wired for 220V.
Can I charge my iPhone and laptop in Korea without a converter?
Yes, virtually all modern phone chargers, laptop bricks, and camera chargers are rated 100–240V, so a simple Type C adapter is all you need. Check the small print on the charger for "100-240V" to confirm before plugging in.
