Plug adapter for South Korea from the United States
What travellers from the United States need to charge and power their devices in South Korea: plugs, voltage and frequency, with the rest of the trip basics below.
Plug adapter
Needed
Bring a Types C and F adapter (or a universal one that covers both).
Voltage
Higher: 220 V
The United States 120 V → South Korea 220 V. Devices made for 110–120 V only need a step-down converter.
Frequency
Same
60 Hz → 60 Hz.
Your plug, their socket
does not fit

Your devices in South Korea
Look for the “INPUT” line on the charger or label. A range such as 100–240V ~ 50/60Hz means the device adapts by itself and needs only a plug adapter.
| Device | Usually | In South Korea |
|---|---|---|
| Phone, tablet and laptop chargers | 100–240 V | Plug adapter only |
| Camera and power-bank chargers, e-readers | 100–240 V | Plug adapter only |
| Electric shavers, toothbrushes | often 100–240 V; check | Check the label: single-voltage ones need a converter |
| Hair dryers, straighteners, curling irons | single voltage | Will burn out on 220 V: buy a dual-voltage model or use the hotel's |
| Kettles, irons, travel cookers | single voltage, high power | Leave at home: converters for these are heavy and costly |
A plug adapter does not change voltage. Plugging a 120 V-only appliance into 220 V through an adapter will destroy it within seconds and can start a fire.
