230 V · 50 Hz on Type K, Type C, Type E, Type F.

Danish sockets are the smiling Type K — two round pins plus a half-round earth — at 230 V and 50 Hz, with Type E and F outlets also permitted in newer installations. Europlugs fit everywhere. A Schuko plug pushes into a K socket and works, but its earth connection is not made, so earthed appliances deserve a proper adapter.

The voltage window

A nominal 230 V supply may legitimately sit anywhere between 207 and 253 V (±10%). Dual-voltage gear (marked 100–240 V) shrugs at all of it.
