A mini fridge is a compact refrigeration unit designed to store food and beverages in small spaces. Typically measuring between 1.5 to 4.5 cubic feet, it is ideal for dorm rooms, offices, or small apartments. Mini fridges often come with adjustable shelves and a small freezer compartment, making them versatile for various storage needs. These appliances are energy-efficient and can be powered by standard electrical outlets. Many models feature a reversible door, allowing users to customize their setup. Mini fridges are popular for keeping snacks, drinks, and leftovers easily accessible without taking up much room.
