Travel Adapter for Denmark: Do You Need One? (United States β Denmark)Adapter Needed
If you're heading to Denmark from the United States, sorting out the power situation is one of the easiest pre-trip wins. Below you'll find the plug types, voltage, and frequency used in Denmark, whether you need an adapter, and which devices are safe to plug in.
Do you need a travel adapter for Denmark?
Yes, you'll need a travel adapter. the United States outlets use Type A/B plugs, while Denmark uses Type C/E/F/K. Because the two don't overlap, your the United States plugs physically won't fit Denmark's sockets without an adapter. Pick one up before you leave, since airport and hotel prices are usually marked up.
What plugs and sockets does Denmark use?
Denmark uses these power plug types: Type C (Europlug): two round pins, ungrounded, and the most widely used plug across Europe; Type E: two round pins with a hole for the grounding pin in the socket, used in France and Belgium; Type F (Schuko): two round pins with grounding clips on the sides, standard in Germany and much of Europe; Type K: two round pins with a grounding pin, used in Denmark. Outlets run at 230V and 50Hz. Coming from the United States (Type A/B), you'll want a Type C/E/F/K adapter to match these sockets.
Voltage and frequency in Denmark
Denmark supplies 230V at 50Hz, which differs notably from the 120V used in the United States. This matters most for single-voltage, high-wattage appliances such as hair dryers, straighteners, curling irons, and electric kettles. Plugging a 120V-only device into a 230V outlet can overheat or destroy it. Check each device's label: if it reads "INPUT: 100-240V" it handles both and you only need a plug adapter; if it lists a single voltage, bring a voltage converter or leave it home.
Will your devices work in Denmark?
Phones, tablets, laptops, and camera chargers are nearly always dual-voltage (100-240V), so they work in Denmark with just a Type C/E/F/K plug adapter, and no converter is required. The devices to watch are heat-based appliances: hair dryers, flat irons, and travel kettles are often single-voltage and can fail on Denmark's 230V supply. Many travelers simply buy a dual-voltage travel version or rely on the hotel's hair dryer.
What travel adapter should you buy for Denmark?
For Denmark, look for an adapter that converts your Type A/B plug to Type C/E/F/K. A universal travel adapter is the most flexible choice, since it covers Denmark plus most other destinations and usually adds built-in USB and USB-C ports so you can charge several devices from one socket. If you only ever visit Denmark, a dedicated Type C/E/F/K adapter is smaller and cheaper.
Tips for charging your devices in Denmark
Pack at least one adapter per traveler, and consider a small power strip from home, which turns a single Denmark outlet into several. Ordering online before you fly is almost always cheaper than airport kiosks.
