As you go off to college you are gong to need to get a few things for your dorm room and what would be a dorm room without a mini refrigerator to go in there as well. What is the purpose of a mini refrigerator? The purpose is that it is so much smaller then a normal one and it can fit just about anywhere. You do not need no special outlet or plug to have it plugged in somewhere, they are great for dorm rooms, shops, break rooms at a store, and so forth and so on. They also come in many different colors like black and white.
