What's the voltage in Korea?

1.？ The two round holes on the power socket are the places where the power plug is connected, just like those in France, Germany, Australia, Greece and Turkey.

2.？ The voltage in South Korea is 220v, but the frequency is 60Hz, which is 10Hz higher than that in China. Generally, China can be used directly in Korea. If your electrical appliance is of other voltage specifications or the plug does not match, and you don't have a transformer or adapter, you can borrow it from the hotel reception desk. Transformers or adapters can also be purchased at duty-free shops and convenience stores in Incheon Airport or Longshan Electronic Commercial Street.
