Denmark Power Plugs, Wall Sockets & Electrical Outlets
In Denmark, power plugs and sockets (electrical outlets) of Type C (CEE 7/16 (Europlug), two round pins, ungrounded), Type E (CEE 7/5, two round pins plus hole for socket grounding pin, grounded), Type F (CEE 7/4 (Schuko), two round pins with grounding clips on sides, grounded) and Type K (DS 60884-2-D1, two round pins plus grounding pin (similar to type f with additional ground pin), grounded) are used. Wall sockets run at 230V and 50Hz. Check if you need a travel adapter, electrical adapter or voltage converter before travelling to Denmark.

Understanding Denmark's Power Plugs and Sockets
The Denmark power plug is officially known as Type K, a Danish standard defined by DS 60884-2-D1. It features two round 4.8mm pins plus a grounding pin, giving it a similar look to the German Type F Schuko plug but with an additional earth pin positioned at the bottom. Denmark's AC power plugs and sockets run on a 230V, 50Hz electrical system, which is standard across most of Europe. Type K outlets are found throughout Denmark and Greenland, with limited use in Bangladesh and Senegal, making it one of the less common plug standards worldwide.
Grounding and the Earth Pin
Type K sockets are built for grounded, 16A connections, and the position of the grounding pin is unique compared to every other European plug type. This means that while a Type K socket-outlet will physically accept Type C, E, and F plugs, only a genuine Type K plug makes contact with the earth pin correctly. Plugging in an E or F device without a matching adapter will supply power but not a verified ground connection, so it's worth checking grounding compatibility before relying on an adapter for high-power or safety-critical appliances.
Do All Sockets in Denmark Look the Same?
Not entirely. While Type K remains the official Danish standard, some installations are transitioning toward broader Type E/F compatibility, meaning travelers may occasionally encounter sockets that behave slightly differently depending on the building's age. The recessed socket design used in Denmark helps protect against accidental contact with live components regardless of the exact variant installed. Type C Europlugs, used widely for low-power electronics, fit into Type K sockets without any adapter needed, though they won't provide grounding.
Denmark Travel Adapter Guide
Visitors bringing electronics from outside Europe will typically need a travel adaptor to fit Denmark's Type K sockets. Two-pin Type C Europlugs, common on phone and laptop chargers, plug directly into Danish outlets without any adapter, since Type K sockets accept them. However, appliances with Type E, F, or other grounded plug styles will need a proper Type K adapter to ensure both a physical fit and a genuine earth connection.
- A Type K adapter (or universal adapter with a Type K/European setting) for grounded appliances
- Devices with Type C Europlugs generally need no adapter in Denmark
- A voltage check on your devices, since Denmark runs on 230V, 50Hz
- A grounded adapter specifically if using high-power appliances like hair dryers or kettles
Frequently Asked Questions
It depends on your plug type. If your device uses a two-pin Type C Europlug, it will fit directly into Danish Type K sockets without an adapter. If your device uses a Type E, F, or non-European plug, you'll need a Type K travel adaptor to fit the socket and maintain proper grounding.
Pack a Type K adapter, or a universal travel adaptor with a European/Type K setting, especially for grounded appliances. If your devices already use Type C Europlugs, such as many phone and laptop chargers, you likely won't need an adapter at all since these fit directly into Danish sockets.
Denmark uses the Type K plug, a Danish standard with two round 4.8mm pins plus a grounding pin, resembling a Type F Schuko plug with an added earth pin. Type K sockets also accept Type C Europlugs, and often physically fit Type E and F plugs, though only genuine Type K plugs receive proper grounding.
Denmark operates on a 230V electrical system at 50Hz, which is the standard used across most of Europe. Travelers from regions with different voltage systems should check that their devices are compatible with 230V before plugging in.
