Travel adapter from South Korea to Tonga

Compare the plug shapes, voltage and frequency in South Korea and Tonga, and find out which adapter you need before you travel.

Adapter required

Yes — coming from South Korea, you will need a travel adapter for Tonga. South Korea uses Type C/Type F plugs, and Tonga 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.

Frequency differs (60 Hz vs 50 Hz). Rarely an issue for most electronics, but can affect motor-driven devices like clocks and shavers.
