What a Type K plug is

Two round pins plus a U-shaped earth pin (Denmark and Greenland). A Type K socket accepts the Europlug (Type C); the grounded Type K plug fits only a Type K socket.

Remember: the plug shape says nothing about the voltage. A Type A plug fits sockets in both the US (120V) and Japan (100V); a Type C plug fits 220–240V sockets across Europe and much of Asia. Always check the voltage of your destination before plugging in a single-voltage device.
