Quick Answer: 220V · 60Hz · Type C/F
Korea runs on 220 volts at 60 Hz. Wall outlets accept the European-style round pins: Type C (ungrounded) and Type F (Schuko, grounded). If your charger label says “100–240V, 50/60Hz,” you only need a plug adapter. Single-voltage (110V-only) appliances require a step-down converter.

Plug Types Explained: C vs F (and why grounding matters)
Type C is the slim, two-pin Europlug—great for phone, camera, and other low-power chargers. Type F adds side grounding clips and is recommended for laptops, metal-body devices, and higher-wattage gear. Most in-wall receptacles are recessed Type F and accept both Type C and F plugs.
Compatibility at a glance
Adapter vs. Converter: Read the label first
If your device/charger reads “Input: 100–240V ~ 50/60Hz,” you only need a plug adapter. Single-voltage 110V appliances (common with hair dryers and stylers) need a step-down converter. For high-draw devices, size your converter with 2× headroom to handle startup surges.
Device quick checks
- Phones/tablets/cameras: dual voltage → adapter only
- Laptops: dual voltage → prefer grounded Type F
- Dryers/straighteners: often single-voltage → converter or local model
- Electric shavers/toothbrushes: check the brick or base
- High-watt kitchen/camping gear: use a local 220V model
What to pack (lightweight, max compatibility)
One Type F + one or two Type C adapters, a dual-voltage multi-port USB charger (65–100W), and a compact KC-marked 220V power strip cover most scenarios. Bring a step-down converter only if you must run 110V-only appliances. Keep everything in a small pouch for security checks.
Safety & durability tips
- Check KC mark and current rating (often 16A/250V) on strips/adapters
- Avoid overloading multi-outlet strips with high-watt devices
- Place converters in ventilated areas—converters get hot
Where to buy/borrow in Korea (airport & city)
At Incheon International Airport, convenience and general stores sell Type C/F adapters; terminals provide charging zones with 110V/220V outlets and USB. Hotels often lend or sell adapters at the front desk. In the city, convenience stores, variety shops, and electronics markets carry a wide range.
Charging etiquette (airport/lounge/cafés)
- Rotate during peak times; avoid “reserving” outlets with unattended gear
- Match device voltage to outlet (don’t mix 110V-only devices on 220V)

Safety & standards (KC mark and KS C 8305)
KC certification is Korea’s safety conformity system for electrical goods (including power strips and chargers). When shopping locally, look for the KC mark and rated current/voltage on the label. Household plugs and sockets follow the Korean standard KS C 8305, aligned with IEC families; modern recessed wall sockets are Type F and accept both C/F plugs.
One-minute checklist
- KC mark & rating → plug type → device label (100–240V?)
- Bring a converter only for 110V-only appliances
- Ventilate converters; avoid bedding/curtains around them
FAQ
Bathroom 110V outlets? Some hotels provide limited 110V “shaver” outlets—always check the label and watt limits. Can one multi-port charger power the family? Yes if dual-voltage and with sufficient total wattage. Can I run a dryer via a small adapter? No—adapters don’t change voltage; use a proper converter or local 220V device. Charging on the go? Many cafés provide outlets/USB; Incheon Airport has 110V/220V/USB charging zones.
