What is a Small Fridge?

A small fridge, also known as a mini fridge, is a compact refrigerator designed to perform the same functions as a standard refrigerator but on a smaller scale. It is ideal for keeping food and beverages cold. Typically, mini fridges have a capacity ranging from 1.7 to 4.5 cubic feet and come in either square or rectangular shapes. Some models include a freezer compartment, but this varies by design.

How Does a Small Fridge Work?

Small fridges operate similarly to larger refrigerators. They contain several key components: a compressor, a condenser, an evaporator, an expansion device, and a thermostat. The compressor circulates refrigerant through the system and increases pressure in the hot part of the circuit. The condenser expels heat from the refrigerator, causing the back of the fridge to feel warm. The evaporator cools the refrigerator's interior elements by turning refrigerant from liquid to gas. The expansion device, often a capillary tube, facilitates this process. Finally, the thermostat regulates the fridge's temperature by turning the compressor on and off as needed.

Types of Mini Fridges

Cube Mini Fridge
Cube mini fridges are portable and can be easily transported and assembled. They are often used in dorm rooms, offices, or small apartments. Cube mini fridges are typically quiet and can operate on a 12-volt power supply, making them suitable for camping or RV use.

Mini-Bar Fridge

Mini-bar fridges are designed to store beverages and are often found in hotel rooms or home bars. They can be built into cabinetry and sometimes feature glass doors to display contents.

Mini Wine Cellar

Mini wine cellars are designed to store wine bottles at the optimal temperature for preservation and enjoyment. They can hold several bottles and maintain temperatures suitable for both red and white wines.

Portable Mini Fridge

Portable mini fridges are extremely compact and lightweight, often using thermoelectric technology. They are perfect for travel and can be powered by a car's cigarette lighter.

Medium-Sized Mini Fridge

These fridges are larger than cube mini fridges and often feature multiple shelves and a freezer compartment. They use compressor technology for cooling and are suitable for more extensive food storage needs.

How to Use a Compact Refrigerator

Place your mini fridge on a flat surface away from direct sunlight and heat sources. Ensure there is adequate space around the appliance for proper air circulation.

Starting Up

Set the fridge to a medium temperature initially. Adjust the thermostat to achieve the desired temperature for your stored items.


Regularly defrost the freezer if frost accumulates. Clean the interior, seals, and coils periodically to maintain efficiency and hygiene.
