Last reviewed · sourced from IEC TC 23 and national electricity standards
Your answer: Czech Republic → South Korea
Plug adapter
Not needed
Both Czech Republic and South Korea use Type C. Your plug fits the socket as-is.
Voltage converter
Not needed
Both countries run on 230V (at 50Hz vs 60Hz — a frequency difference most devices don't notice). Your devices work as-is.

What this means for your trip
Travelling from Czech Republic to South Korea? Easy trip, electrically speaking — you don't need a plug adapter or a voltage converter. Both countries use the same outlet shape and the same voltage standard, so every charger, phone, and laptop you'd normally pack works the moment you land.
Both countries run on Type C outlets. You don't need a shape adapter at all — just plug in the way you do at home.
Voltage is the same on both ends (230V vs 230V, 50Hz vs 60Hz), so every charger that works at home works in South Korea without modification. No voltage converter, no hunting for "100-240V" on the brick.
Frequently asked
Do I need a travel adapter for South Korea from Czech Republic?
No. Both Czech Republic and South Korea use Type C outlets, so your plug fits the socket as-is.
What type of plug does South Korea use?
South Korea uses Type C and Type F outlets at 230V, 60Hz. Two round pins. Widespread across Europe, South America, and parts of Asia.
What's the voltage in South Korea?
South Korea runs on 230V at 60Hz. That's on the high-voltage standard, matching than Czech Republic's 230V supply. Most modern phones, laptops, tablets, and camera chargers are dual-voltage (check for "100-240V" on the brick) and work on either. Single-voltage devices like hair dryers, curling irons, and travel kettles will not — bring a dual-voltage travel version or a voltage converter.
Are Czech Republic chargers dual-voltage?
Most — but not all. Check the charger brick for a line that reads something like "INPUT: 100-240V, 50/60Hz." If you see that, the charger works on either voltage standard and you only need a plug adapter. If it lists just "120V" (or just "230V"), it's single-voltage and can't be plugged straight into the other side without a voltage converter.
