Compare the plug shapes, voltage and frequency in South Korea and Kiribati, and find out which adapter you need before you travel.
Adapter required
Yes — coming from South Korea, you will need a travel adapter for Kiribati. South Korea uses Type C/Type F plugs, and Kiribati uses Type I, 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.
