Knowing what is a good 12v mini car fridge and knowing the basics of refrigeration can be helpful. In most refrigeration systems, there are three important components: the compressor, the chemical refrigerant, and the piping through which the refrigerant flows.

    The refrigerant - usually Freon - is the magic that makes good cooling possible. At room temperature, it is a gas, but when the temperature drops, it turns into a liquid. However, the temperature is not the only factor causing this state change. The same goes for pressure, which is where the compressor comes in.

    The compressor pressurizes the refrigerant, which in turn warms the gas. Once heated, it becomes liquid. If you've ever put your hand on the side of a refrigerator and felt the heat it produces, you've felt the effect of the compressor turning the refrigerant from a gas to a liquid.

    When the refrigerant turns into a liquid, it moves through a network of pipes and pipes that run through the walls of the refrigerator. But it won't stay that liquid. As it passes through the pipe, it cools to ambient temperature, which causes it to turn back into a gaseous state. When it does so, it actually absorbs heat from the surrounding area. In other words, the refrigerator doesn't really cool the interior space, it draws the heat out. This is the premise behind most refrigeration systems, whether it's a refrigerator in a kitchen or an air conditioner unit in your home.

    As you might imagine, compressors require a lot of energy to get the job done. If you try to connect the refrigerator to the car battery using the inverter, you will drain the battery in a few minutes. This brings us to the topic of batteries and power.

    Batteries are measured in amp-hours. In theory, if you have a 100 amp hour battery, you can run a device that draws 10 amps for 10 hours. But that's theoretical, and in the real world, there's more.

    The battery is designed to be optimized for two different uses. They either pull out a very high current for a short period of time or a low current for a long period of time.

    Most 12v appliances require deep cycle batteries. These types of batteries are designed for low discharge, and they are more suitable for powering devices that require a steady but low power current.
