It's always good to know if you'll need an adapter or transformer for the electrical outlets abroad. Most of Scandinavia uses 220v and has the C/F Europlug types. Here's a list of the electrical outlet types you'll find in Denmark, Sweden, Norway, and other countries:

Sweden uses the Europlug (Type C & F) for electricity, with two round prongs. If you're bringing a hair dryer or laptop, check if the label near its power cord shows 100-240v and 50-60 Hz. If it does not, you will need a "step-down transformer" (also called a converter). The converter will reduce the 220 volts from the outlet to provide just 110 volts for the appliance. These converters cost a little more than simple adapters. Compare prices of converters here.

The same plug (a C & F formed Europlug) and the same warnings are valid for Norway. If you bring small appliances, be careful. The shape adapter may not be enough. While basically all personal electronics in recent years will accept both voltages, some older, smaller appliances don't work with the 220v in Europe.

Electricity in Iceland uses the Europlug/Schuko-Plug (CEE types), which has two round prongs. Iceland also uses 220v. While basically all personal electronics in recent years will accept both voltages, some older gadgets won't work with 220v. So leave the Gameboy and the hairdryer at home (most hotel rooms will contain a hairdryer anyway).

Finland differs a bit. Electrical plugs in Finland need two round prongs. They can be the ungrounded Europlug Type C or the grounded Schukoplug Type E/F. If your travel appliance works with the strong European 220 voltage, you'll only have to change the shape of your existing power plug to fit into a Finnish outlet. And that's it. These simple plug adapters are relatively cheap and you can compare adapter prices.Continue to 5 of 5 below.

It's not too hard to find out what kind of plug or converter you need for electrical outlets in Denmark. Most laptops will automatically work with 220-230 volts (check the back of your laptop for power input markings.) That means you'll only need an adapter to change the shape of your power plug to fit into an outlet in Denmark. These power adapters are relatively cheap and you can Compare Prices.
