Norway runs on a 230 V system and a 50 Hz frequency.
The power outlets take a C or F European standard plug with two round pins.
If travelling from the USA or a country that uses 110 V, we recommend using a 230 V converter. These can be bought at most airports and luggage shops and are also available at certain stores in downtown Tromsø.
The tap water in Tromsø is very pure and clean and is often better than bottled water. It is safe to drink, but in the larger hotels we recommend letting the tap run a bit first so you get cold water.
Fluoride is not added to Norwegian tap water and only very small amounts occur naturally. Most pharmacies in the city sell fluoride tablets if you require these.
