Travel adapter from South Korea to Nigeria
Adapter Required
Yes — coming from South Korea, you will need a travel adapter for Nigeria. South Korea uses Type C/Type F plugs, and Nigeria 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.
