South Korea outlet FAQ
Can I charge my phone in South Korea without a converter?
Yes. Phone and laptop chargers are dual-voltage (100–240V) — you only need a plug adapter (Type C/F).
Is 220V dangerous for US devices?
Only for single-voltage (120V-only) devices like hair dryers — those need a voltage converter. Dual-voltage gear is fine on an adapter.
What plug type does South Korea use?
South Korea uses Type C, F sockets at 220V / 60Hz.
