Travel Adapter for Denmark: Do You Need One? (Mongolia → Denmark)No Adapter Needed

Traveling from Mongolia to Denmark means crossing into a different electrical system. Here's a complete breakdown of the sockets, voltage, and the right adapter to bring for Denmark, so nothing you packed ends up useless at the hotel.

Do you need a travel adapter for Denmark?

Good news: you generally don't need a plug adapter. Both Mongolia and Denmark use Type C/E outlets, so your existing plugs should fit Denmark's sockets directly. A universal adapter is still worth keeping in your bag as a backup for future trips.

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. Since Mongolia also uses Type C/E, your plugs already match.

Voltage and frequency in Denmark

Denmark runs on 230V at 50Hz, the same as Mongolia (230V, 50Hz). That means voltage isn't a concern here, since your appliances won't be over- or under-powered, so no voltage converter is needed.

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 your existing plug, and no converter is required. Even heat-based appliances like hair dryers and straighteners should run fine given the matching 230V supply, though it's always worth a quick label check.

What travel adapter should you buy for Denmark?

Because Mongolia and Denmark share Type C/E outlets, you don't need a special adapter for this trip. A universal travel adapter is still a smart, inexpensive backup if you plan to travel elsewhere, and the better ones add USB-C fast charging to free up your charger.

Tips for charging your devices in Denmark

Many Denmark hotel bathrooms have a low-wattage "shaver only" socket that is fine for razors and toothbrushes but not for charging phones or running hair dryers. Use the main wall outlets with your adapter for everything else.
