United States of America to South Korea
Traveling from United States of America to South Korea? You'll need an adapter, and a voltage converter for the 100V difference.
Need an Adapter?
Yes! Yes, you need a Type A/B to Type C/F adapter
Need a Voltage Converter?
Maybe — check if your devices support 220V
🔍 Why This Route Matters
If you're heading from United States of America to South Korea, understanding the electrical differences can save you from dead phones and ruined travel adapters. Type A/B (United States of America) and Type C/F (South Korea) are fundamentally different plug shapes. Voltage is where you need to pay attention. 120V in United States of America versus 220V in South Korea means you'll need more than just an adapter. National animal is the Korean. This isn't a route where you want to figure things out at the hotel.
Side-by-Side Comparison ⚡
🎯 What Locals Know (That Tourists Don't)
- ✦Uses 12H time format (e.g., 11:00 PM)
- ✦Temperature measured in Celsius (°C)
- ✦Electrical system uses 220V at 60Hz with Type C/F plugs
- ✦Tap water safety: drinkable
- ✦Convenience stores and pharmacies often stock basic adapters for a fraction of airport prices
- ✦When in doubt, look for "INPUT: 100-240V" on your device. That means it's safe without a converter.
What You Need for This Trip 🧳
Plug Adapter
RequiredUnited States of America's Type A/B plugs won't fit South Korea's Type C/F outlets.
Voltage Converter
May Be RequiredSouth Korea uses 220V vs United States of America's 120V. Most modern electronics handle this automatically.
Airport & Arrival Tip
Most international travelers arrive through ICN, which has decent charging infrastructure. Look for dedicated device charging kiosks in the arrivals hall (some require payment, others are free). If you forgot an adapter, check duty-free shops before overpriced gate kiosks. Prices vary wildly. Many ride-share drivers have USB chargers available. Don't hesitate to ask. First day is best for sorting out power issues. You'll be less stressed and more alert.
Packing Advice
Pack both a plug adapter (Type A/B to Type C/F) AND a voltage converter (120V to 220V). You'll need both. Consider a universal travel adapter with USB ports. It'll work for South Korea and future trips. Power banks must go in carry-on luggage (not checked bags). TSA and international rules are strict about this. Pack extra charging cables. They're easy to lose and expensive to replace abroad. Laptops and phone chargers are almost always dual-voltage (100-240V). Converters are usually for other items. Test all your adapters at home before packing. Discovering a faulty adapter at your hotel is frustrating.
Seasonal Considerations
South Korea's seasons affect more than just your wardrobe; they impact your device strategy too. **Summer travel:** Summer heat means aggressive air conditioning. Battery life suffers in cold indoor environments. **Winter travel:** Shorter days mean more screen-on time for navigation and entertainment. Plan accordingly. **Holiday season:** Year-end travel often means budget hotels with fewer outlets. Plan device priorities. Whatever the season, arrive with everything fully charged. You can't predict your first day's access to power.
