Mini fridges are useful when a fridge is needed, but there is not a lot of space. Popular examples include dorm rooms and offices, but mini fridges are also becoming popular at home.
At home, mini fridges can be used for extra storage in a garage or to have snacks and drinks available in a media room. They are popular to have by wet bars or on the porch. Some people have also converted mini fridges into "kegerators," or a fridge that is designed to pump beer from a small keg that is kept cool by the fridge. Mini fridge models that have separate freezer sections can be more useful for the dorm room or office, while specialized fridges that are designed for drinks only can be more useful for a home wet bar.
