Do You Need a Plug Adapter for Denmark?
Denmark runs on 230 volts at 50 Hz and uses Type K sockets – the standard across continental Europe in all but plug shape. Whether you need a plug adapter for Denmark comes down to where you are coming from: visitors from the UK, US and beyond do, while most of mainland Europe slots straight in. Here is exactly what to bring.
Do you need a plug adapter for Denmark?
It depends on your country. Denmark uses 230V / 50Hz electricity and Type K sockets. If you are coming from the UK, US, Australia or most places outside continental Europe, yes – you will need a plug adapter for Denmark. If you are travelling from mainland Europe, your plugs will generally fit without one. The good news is that an adapter is cheap, small and easy to pick up before you go or on arrival.
Denmark uses Type K sockets at 230V/50Hz. UK, US and non-European visitors need a plug adapter; most of mainland Europe fits already, and the European “Europlug” (Type C) works everywhere in Denmark.
The sockets
The Danish standard socket is Type K, with two round power pins and an earth pin. Helpfully, the common European Type C “Europlug” (two round pins) fits every Danish socket, and modern Danish sockets also accept Type E and Type F (Schuko) plugs used across much of Europe. That is why travellers from countries like Germany, France, Spain and Italy usually plug in directly.
Voltage and frequency
Denmark, like the rest of Europe, runs on 230 volts at 50 hertz. For UK and European visitors this is the same voltage you use at home, so only the plug shape differs. For US and Canadian visitors (110-120V at home), the higher voltage matters: dual-voltage devices are fine with just an adapter, but single-voltage appliances need a converter (see below).
What you need by country
- UK (Type G): a plug adapter – same voltage, different plug.
- US / Canada (Type A/B): a plug adapter, plus a voltage check – bring a converter for anything not dual-voltage.
- Mainland Europe (Type C/E/F): usually no adapter needed; the Europlug fits.
- Australia / New Zealand (Type I): a plug adapter – same voltage.
- Elsewhere: a universal travel adapter covers you.
What to buy
The simplest option is a universal travel adapter, or a basic Europe/Type C adapter if you only travel in this region (Type C plugs into Danish sockets without issue). Models with built-in USB ports are handy for charging phones and tablets without using your charger’s plug at all. Buy before you travel, or find adapters at the airport, electronics shops and many supermarkets.
Charging your devices
Most modern electronics – phone chargers, laptops, camera and tablet chargers – are dual-voltage, marked “INPUT: 100-240V” on the plug or brick. For these you only ever need a plug adapter, never a converter. Check that label: if a device is rated for 120V only (some hair dryers, straighteners and small appliances), you will need a voltage converter as well, or simply leave it at home.
Read the small print on the charger. “100-240V” means a plug adapter is all you need. A single “120V” rating means you also need a converter.
Questions and answers
What plug adapter do I need for Denmark?
Denmark uses Type K sockets at 230V/50Hz. UK, US, Australian and other non-European visitors need a plug adapter; a universal adapter or a Type C Europlug adapter both work.
Does Denmark use the same plugs as the rest of Europe?
Largely – the European Type C Europlug fits all Danish sockets, and modern sockets also take Type E and F plugs, so most mainland European visitors plug in directly.
Can I use UK plugs in Denmark?
Not directly – UK Type G plugs do not fit. You need an adapter, but as the voltage is the same (230V) you do not need a converter.
Do US devices work in Denmark?
With a plug adapter, dual-voltage devices (most phone and laptop chargers, marked 100-240V) work fine. Single-voltage 120V appliances also need a voltage converter.
What voltage is Denmark?
230 volts at 50 Hz, the same as the rest of Europe.
