Denmark Electrical Outlets 2026
Plug types, voltage, and frequency for Denmark. Essential info for travelers.
Overview
Denmark operates on a standard voltage of 230 volts and a frequency of 50 hertz. The national standard for electrical outlets is the Type K plug, which features a unique three pin design often described as a smiley face, though Type C, Type E, and Type F sockets are also commonly encountered throughout the country.
Do you need an adapter?
Visitors using devices with the standard two pin European Type C plug will find them compatible with most Danish sockets. Travelers from regions like North America or the United Kingdom should bring a high quality travel adapter that supports the specific Type K grounding pin to ensure a secure and safe electrical connection.
Safety notes
While most modern electronics like laptops and mobile phones are designed for dual voltage use, travelers should always verify that their devices can handle 230 volts before plugging them in. Using a grounding adapter is particularly important for high power appliances to prevent static discharge or electrical shocks that can occur when using non grounded European plugs in Danish sockets.
Frequently Asked Questions
Denmark uses plug type(s) C, E, F, K. Travelers from countries with different plugs will need an adapter.
The standard voltage in Denmark is 230V at 50Hz.
If your home country uses different plug types than C, E, F, K, you will need a universal travel adapter.
The most common plug in Denmark is Type K, which has two round pins and a third earthing pin. Many Danish outlets also accept the standard Type C Europlug, and some modern installations now include Type E or Type F sockets which are standard in other parts of Europe.
Most American electronics require a voltage converter because they are rated for 120 volts, whereas Denmark uses 230 volts. However, many modern device chargers are dual voltage and can operate safely if the label indicates a range of 100 to 240 volts, requiring only a physical plug adapter.
Yes, grounding is essential for safety with larger appliances like hair dryers or laptops with metal casings. While a two pin Type C plug will fit in a Type K socket, it does not provide a grounding connection, so using a specific Type K grounded adapter is recommended for high wattage equipment.
