Each section of the world, and sometimes even counties, vary with the sort of plugs that they have (Denmark is by far my favorite with its little smiley face looking plug!). This means that you can’t just plug in your electronics or cords just anywhere. You need a specific kind of adapter to change what you have into something that can be plugged in wherever you go.
If you are planning on traveling a lot while on your study abroad experience, it is a good idea to buy an adapter that comes with interchangeable plug types. This will allow you to only carry one adapter without having to worry about whether or not it will work around the world. For example, note that the UK outlet is different than the rest of Europe.
When it comes to buying adapters to convert our American plugs into different plugs around the world, there are a variety to choose from. Here are some links where you can buy some for a decent price:
