Plug Adapter & Power Outlet Guide
If you are planning a trip to Denmark, it is important to understand the country’s electrical system so you can safely use your electronics during your visit. Different countries use different types of power outlets and voltage systems, which means travelers often need a travel plug adapter to charge their devices.
If you are traveling to Denmark from the United States, you will need a plug adapter because Denmark uses different outlet types than those found in North America. Denmark primarily uses Type C, Type E, Type F, and Type K power outlets, while the United States uses Type A and Type B plugs.
Denmark’s electrical system operates on 230 volts and 50Hz, compared to 120 volts and 60Hz in the United States. Because of this difference, some appliances may require a voltage converter in addition to a plug adapter.
Understanding Denmark’s plug types and voltage system will help ensure that you can safely charge your phone, laptop, camera, and other travel electronics while visiting the country.
Power Plugs and Sockets in Denmark
Denmark uses several types of power plugs.
Type C Plug
Type C plugs are widely used across Europe and many other parts of the world.
Characteristics of Type C plugs:
Two round pins
No grounding pin
Commonly used for small electronics
This outlet is often used for chargers for devices such as phones, cameras, and tablets.
Type E Plug
Type E plugs are commonly used in parts of Europe and can also be found in Denmark.
Characteristics of Type E plugs:
Two round pins
One grounding pin in the socket
Provides additional safety for grounded appliances
Type F Plug
Type F plugs are also widely used throughout Europe.
Characteristics of Type F plugs:
Two round pins
Two grounding clips on the side
Also known as the Schuko plug
Type F outlets are commonly used for grounded appliances and electronics.
Type K Plug
Type K plugs are the traditional Danish plug type.
Characteristics of Type K plugs:
Two round pins
One grounding pin in the socket
Similar to Type F but with a different grounding system
Type K outlets are commonly found in older buildings in Denmark.
Because Denmark uses round-pin sockets, American flat-pin plugs will not fit directly into Danish outlets. Travelers from the United States will need a plug adapter.
Why You Need a Travel Adapter for Denmark
A travel plug adapter allows you to plug American electrical devices into foreign outlets.
The adapter works as a bridge between the flat prongs used in US plugs and the round sockets used in Denmark.
It is important to remember that plug adapters only change the shape of the plug. They do not change the voltage of electricity.
If you plug a device designed only for 110–120 volts into a 230-volt outlet, it may damage the appliance.
For most modern electronics like phones and laptops, a simple plug adapter is usually all that is required.

Voltage in Denmark
Denmark operates on 230 volts with a frequency of 50Hz.
Here is how that compares with the United States:
| Country | Voltage | Frequency |
|---|---|---|
| Denmark | 230V | 50Hz |
| United States | 120V | 60Hz |
Because Denmark’s voltage is higher than in the United States, some appliances may not work safely without a voltage converter.
When You Need a Voltage Converter
Travelers sometimes need a voltage converter for high-power appliances designed specifically for North American voltage.
Common appliances that may require converters include:
Hair dryers
Curling irons
Electric shavers
Hair straighteners
Coffee makers
Using these devices without a converter can cause:
Overheating
Electrical damage
Potential fire hazards
A voltage converter reduces Denmark’s 230V electricity down to 110V so American appliances can operate safely.
Can You Use Your Electronics in Denmark?
The good news for travelers is that most modern electronics are dual voltage.
This means they can safely operate on both 110V and 230V electrical systems.
Devices that are usually dual voltage include:
Smartphones
Tablets
Laptop chargers
Camera chargers
Power banks
Electric toothbrush chargers
For these electronics, you only need a plug adapter, not a voltage converter.
How to Check if Your Device Is Dual Voltage
To determine whether your device supports dual voltage, check the label on the charger or power adapter.
Look for wording such as:
INPUT: 100-240V, 50/60Hz
If you see this range, the device can safely operate in Denmark.
This label is commonly found on:
Phone chargers
Laptop power supplies
Camera battery chargers
Tablet chargers
If your device lists only 110V or 120V, you should use a voltage converter.
Frequency Differences (50Hz vs 60Hz)
Denmark’s electrical grid runs at 50Hz, while the United States uses 60Hz.
Most modern electronics can operate on either frequency, but some appliances may behave differently.
Devices that may be affected include:
Electric clocks
Motor-driven appliances
Fans
Certain electric shavers
If the device relies on precise motor timing, it may not operate properly.
Travel Power Tips for Denmark
To avoid problems with electricity while traveling, keep these tips in mind:
• Bring a universal travel adapter
• Check if your electronics support 100–240V input
• Avoid using high-power appliances without converters
• Pack a power strip to charge multiple devices from one adapter
• Carry a portable power bank for charging during travel days
These simple steps will help ensure your devices stay charged throughout your trip.
