What Power Plug Do You Need in South Korea?
If you’re planning to visit South Korea, don’t overlook your power needs. Bringing the wrong plug can mean no charging, no laptop, and a lot of frustration. Here’s everything you need to know to stay powered up during your trip.
Power Plug Shape in South Korea
South Korean outlets have two round holes, spaced horizontally. This type of socket is common in many European countries as well, including Germany, France, and the Netherlands.
If your plug has flat blades (like those in the U.S. or Japan), or three rectangular pins (like in the UK), you’ll need an adapter. Some countries use angled flat pins (Australia) or three round pins in a line (Italy), which also require an adapter in Korea.

Plug Compatibility Reference
| Country | Plug Shape Description | Need an Adapter? | Voltage |
|---|---|---|---|
| United States | Two flat blades (parallel) | ✅ Yes | 120V |
| United Kingdom | Three rectangular pins | ✅ Yes | 230V |
| Australia | Two angled flat blades + one vertical | ✅ Yes | 230V |
| Japan | Two flat blades (narrower) | ✅ Yes | 100V |
| Germany / France | Two round pins | ❌ No | 230V |
| South Korea | Two round holes | – | 220V |
Voltage and Frequency
- Voltage: 220 volts
- Frequency: 60 Hz
Most modern devices (like smartphones, tablets, laptops) support dual voltage (100V–240V), so in most cases, you’ll only need a plug adapter, not a voltage converter. But always check your device’s label before plugging in!
❓ FAQ: Using Electronics in Korea
Can I use my U.S. phone charger in Korea?
Yes, but you’ll need a plug adapter. Most phone chargers are dual voltage (100V–240V), so a voltage converter is not needed.
Can I use my Dyson hair dryer or Airwrap in Korea?
⚠️ It depends on the model and where it was purchased. Dyson products sold in the U.S. or Japan typically only support 100–120V and cannot be used in Korea (220V) without a step-down voltage converter. Even with a converter, the product may malfunction, overheat, or pose a fire risk. These devices are not recommended for use without proper voltage support.
What if I forget to bring an adapter?
Some hotels may have one, but it’s better to bring your own. Adapters at airports are overpriced and may be limited.
Is Korea’s voltage safe for my laptop?
As long as your device label says 100V–240V, it will work fine in Korea with a plug adapter.
Travel Tips
- Bring a universal adapter with USB ports—it’s compact and versatile.
- A multi-port USB adapter helps charge multiple devices at once.
- Buy your adapter before the trip to avoid expensive airport purchases.
- Don’t rely on your hotel—availability varies.
Final Thoughts
South Korea’s power system is simple if you’re coming from Europe. But for visitors from North America, the UK, Australia, or Japan, be sure to pack a compatible plug adapter—especially for high-wattage devices.
A tiny plug can make a big difference. Stay charged, stay safe—and enjoy your adventure in Korea.
