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