Plugs and voltage
Korea uses 220 V, 60 Hz with round two-pin plugs (types C and F, the same shape as much of Europe). US and Japanese 110 V plugs need an adapter, and single-voltage devices also need a converter. Most phone and laptop chargers accept 100–240 V; check the label.
Tipping
Tipping is not customary in Korea — not in restaurants, taxis or cafés. Some hotels and fine-dining places add a service charge to the bill; that is the only extra you pay.
