You need a travel adapter, and likely a voltage converter
United States of America: Type A/B · 120V → Denmark: Type C/K · 230V

Plug shape, voltage, frequency — the four things that decide whether your gear works on this route.
The story behind the route.
Why this specific origin → destination pair has the quirks it does — local context the data alone won't show.
United States of America and Denmark represent two distinct electrical worlds. Here's what you need to know before you go. The plug situation is straightforward: United States of America's Type A/B and Denmark's Type C/K don't work together. Voltage is where you need to pay attention. 120V in United States of America versus 230V in Denmark means you'll need more than just an adapter. Getting it right means one less thing to worry about when you land.

- →Electrical system uses 230V at 50Hz with Type C/E/F/K plugs
- →Tap water is safe to drink in most areas
- →Convenience stores and pharmacies often stock basic adapters for a fraction of airport prices
- →Most phone and laptop chargers handle 100-240V automatically (check the fine print on the brick)
What to pack for this route.
One adapter for the plug shape, one converter when voltage bands cross. That covers most of what you need.
A universal adapter covers this route plus 150+ other countries.
Bands differ (120V vs 230V). Hair dryers, curling irons, kettles need a converter — or a dual-voltage replacement.
