The question that always arises, when going on vacation – can I use my normal cords or do I need an adapter? If you’re reading this, my guess is you didn’t forget to look it up before you traveled. That will save you the hassle of finding a shop late at night, when all of your electric devices have died on you.
The power output in Denmark is 230V at 50Hz, which means that you need a transformer for your 110/125V appliances.
In Copenhagen and Denmark in general, we use Type C, E, F and K plugs. Those are the ones with two round pins. The type C plug is also called the Euro-plug and is used in the most part of Europe and actually the whole world – except from noteworthy United Kingdom, North America, Australia, Japan and some more.
Sorry, you guys need a travel adapter along with the transformer.
