Travel adapter from South Korea to Sierra Leone
Adapter Required
Yes — coming from South Korea, you will need a travel adapter for Sierra Leone. South Korea uses Type C/Type F plugs, and Sierra Leone uses Type G, so the pin shapes will not fit any wall socket. The mains frequency is also different (60 Hz vs 50 Hz). This rarely matters for electronics but can affect motor-driven devices like clocks and shavers.
