I'm seeing conflicting information on what type of adapter is needed for Denmark. For most of Scandinavia, the Type C is used. When looking up Denmark specifically, it is saying a Type K (with a 3rd plug for grounding). I have the Type C, wondering if I need to get a Type K as well. Also looked for the multi-type adapters, but they don't have the Type K included. Anyone who has been in Denmark have any problems just using the 2 prong plug adapter (Type C)?
