A mini fridge is a compact refrigerator designed to store food and beverages in small spaces. They are popular in dorm rooms, offices, and bedrooms due to their size, which typically ranges from 1.7 to 4.5 cubic feet. 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 ideal for keeping snacks, drinks, and leftovers easily accessible without taking up much room.
