How Does Electricity & Plugs Work in South Korea?
Last verified: 2025-06 · Asia
1The Quick Answer
South Korea uses Type C and Type F (European-style round-pin) plugs at 220V/60Hz — American visitors need an adapter.
2What You Need to Know
The standard voltage is 220V and the frequency is 60Hz — notably, while the voltage matches Europe, the frequency differs (Europe uses 50Hz), though this is inconsequential for virtually all modern electronics and appliances. Type C (two round pins) and Type F (two round pins with grounding clips) are both used. Travelers from North America (110V, Type A/B) will need a plug adapter and should verify their device's voltage compatibility, though most modern laptops, phones, and cameras are dual-voltage (100-240V). UK visitors (Type G) also need an adapter.
3Practical Tips
Practical Tips
- 1Check your device's power brick for input voltage — if it says '100-240V' (most modern electronics do), you only need a plug adapter, not a voltage converter.
- 2Type C to Type F adapters are inexpensive and widely available at convenience stores and electronics shops like Daiso or electronics markets.
- 3USB-C charging has become near-universal in Korean cafes, hotels, and airport lounges — a USB-C cable covers most modern devices without needing to worry about plug types.
