Comparison with Similar Power Plug Types
Type K is similar to Type E and Type F in basic geometry, and many Type K sockets are designed to accept the ungrounded Type C Europlug. However, grounded plugs are not always cross‑compatible without a proper adapter.
Compatible With
When Traveling TO Countries with Type K
If you're traveling from a country that doesn't use Type K power plugs, you'll need a power plug adapter to physically fit your devices into Type K outlets. Make sure to check voltage compatibility as well - most countries using Type K operate at 230V.
When Traveling FROM Countries with Type K
If you're traveling from a country with Type K to countries with different power plug types, consider a universal travel adapter that includes multiple power plug configurations. This will work in 150+ countries worldwide.
Common Misconceptions
Type K sockets accept all European grounded plugs
Type K is mechanically different from Type E and Type F. While many Type K sockets accept Type C plugs, grounded E/F plugs often require an adapter.
You never need an adapter when traveling between Denmark and other EU countries
Because Denmark uses Type K, many travelers from countries using Type E/F still need an adapter for grounded devices.
Frequently Asked Questions
What countries use Type K power plugs?
Type K power plugs are used in 7 countries, primarily in Africa, Asia, Europe.
Is Type K grounded?
Yes, Type K power plugs are grounded (earthed), providing additional safety for high-power appliances.
Can I use a Type K adapter for all my devices?
A plug adapter only changes the physical shape - it doesn't convert voltage. Check that your devices support the voltage used in your destination country (230V). Most modern electronics are dual voltage (100-240V), but always verify on the device label.
Where can I buy a Type K adapter?
Type K adapters are available at airports, electronics stores, online retailers, and travel shops. For better prices and selection, purchase before your trip. Universal travel adapters that include Type K are also a good option for frequent travelers.
