What voltage does Norway use, and do I need a converter for US devices?
Voltage, frequency and how to read the label on your devices.
Short answer
Norway's mains supply runs at 230 V and 50 Hz, so a US device needs a voltage converter only if its label does not include 230 V. Chargers marked 100–240 V work with just a plug adapter for the type F sockets with two round pins. Devices marked 110–120 V only need a converter.
Why
- Store norske leksikon gives the usual voltage in the Norwegian low-voltage grid as 230 V at a frequency of 50 Hz.
- A CEPT information note for a meeting in Tromsø states that the standard voltage in Norway is 230 V, 50 Hz, and that sockets are type F.
- Visit Norway describes the Norwegian socket as the continental European standard.
Details
A plug adapter only changes the shape of the plug, while a voltage converter lowers 230 V to the voltage the device needs. Check the input line on each charger or appliance, which shows the voltage range it accepts. Plugging a device made only for 110–120 V straight into a Norwegian socket can damage it.
Tip
Check heating devices such as hair dryers and hair straighteners first, and leave single-voltage ones at home if you do not want to carry a converter.
Common misconception
A travel adapter also converts the voltage.
What actually happens
A plug adapter only changes the shape of the plug. A device rated only for 110–120 V still receives 230 V through it, so it needs a voltage converter.
