South Korea outlet FAQ

Can I charge my phone in South Korea without a converter?

A voltage converter is unnecessary only if your charger’s actual INPUT range covers the local supply and frequency, and its manufacturer permits this use. Confirm the exact outlet, plug fit and any required grounding. A typical charger profile does not verify your model.

Is 220⁠V dangerous for US devices?

Do not connect a mismatched single-voltage appliance directly. For high-power heating appliances use a local-voltage model, not a travel converter workaround. Confirm the actual input label, frequency and grounding even for a 100-240V charger.

What plug type does South Korea use?

South Korea uses Type C/F sockets at 220⁠V / 60⁠Hz.
