Travel adapter from Costa Rica to South Korea
Adapter Required
Yes — coming from Costa Rica, you will need a travel adapter for South Korea. Costa Rica uses Type A/Type B plugs, and South Korea uses Type C/Type F, so the pin shapes will not fit any wall socket. Voltages differ (120 V at home vs 230 V abroad), so check the label on each device. Most modern dual-voltage chargers handle the swing without a converter, but heating appliances usually do not.
