From Tonga to Denmark
When travelling from Tonga to Denmark: None of your Tonga plug types fit in Denmark. You will need a travel adapter. Voltage is different (240V → 230V). Check your charger label; if it doesn’t list 230V you’ll also need a voltage converter. Frequency is the same at 50Hz.

About electricity in Denmark
Denmark uses 230V/50Hz with Type C, F, and K sockets. Type K is the Danish three-round-pin standard; many Danish sockets accept C, F, and K in the same hole.
Grid & history
Denmark is the wind-power pioneer of Europe; wind regularly supplies more than half of generation, with strong interconnects to Norway, Sweden, and Germany balancing supply.
Availability
Excellent.
Sockets & hotels
Hybrid sockets that accept C, F, and K are now standard in homes and hotels. Older buildings may have Type K only, in which case Type F (Schuko) plugs technically work but ground contact is offset.
Energy mix
Wind is the largest single source globally per capita.
Practical tips
- A European C/F adapter covers almost every modern Danish socket.
- For older buildings or rural cabins, a dedicated Type K adapter is a safe backup.
