United States of America to Denmark
Traveling from United States of America to Denmark? You'll need an adapter, and a voltage converter for the 110V difference.
Need an Adapter?
Yes! Yes, you need a Type A/B to Type C/K adapter
Need a Voltage Converter?
Yes — 230V can damage single-voltage United States of America devices
🔍 Why This Route Matters
United States of America and Denmark represent two distinct electrical worlds. Here's what you need to know before you go. The plug situation is straightforward: United States of America's Type A/B and Denmark's Type C/K don't work together. Voltage is where you need to pay attention. 120V in United States of America versus 230V in Denmark means you'll need more than just an adapter. National animal is the Danish. Getting it right means one less thing to worry about when you land.

- ✦Electrical system uses 230V at 50Hz with Type C/E/F/K plugs
- ✦Tap water is safe to drink in most areas
- ✦Convenience stores and pharmacies often stock basic adapters for a fraction of airport prices
- ✦Most phone and laptop chargers handle 100-240V automatically (check the fine print on the brick)
What You Need for This Trip 🧳
Plug Adapter
RequiredUnited States of America's Type A/B plugs won't fit Denmark's Type C/K outlets.
Voltage Converter
May Be RequiredDenmark uses 230V vs United States of America's 120V. Most modern electronics handle this automatically.
Airport & Arrival Tip
Most international travelers arrive through CPH, which has decent charging infrastructure. International terminals typically have USB charging stations near gates. Bring your own cable though. 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. If your adapter isn't working, hotel front desks can usually lend you one (or direct you to the nearest store).
Packing Advice
Pack both a plug adapter (Type A/B to Type C/K) AND a voltage converter (120V to 230V). You'll need both. Look for adapters with surge protection. Cheap ones can fail and damage devices. High-capacity power banks (20,000+ mAh) are worth the weight if you're a heavy device user. 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
Power needs vary by season when traveling to Denmark. Here's what changes throughout the year. **Summer travel:** Hot weather drains phone batteries faster than you'd expect. Keep devices cool when possible. **Winter travel:** Cold weather kills battery life quickly. Keep devices close to your body to maintain charge. **Holiday season:** Holiday season means packed accommodations. Claiming outlets early is strategic. Plan for worst-case scenarios with your power setup. You'll be glad you over-prepared.
