A typical car battery isn’t designed for low discharge, so not every 12v appliance can run efficiently off of one. But if you leave your headlights on, your battery won’t last long at all, even though headlights only draw around 10 to 15 amps. But these kinds of batteries are meant to push a high output all at once-exactly what a starter needs to engage the motor. Most car batteries are rated between 50 and 100 amp-hours. They either push out a very high current in a short amount of time or they push out a low current for an extended amount of time. ![]() But that’s in theory, and in the real world, there’s a little more to it.īatteries are designed to be optimized for two different uses. In theory, if you have a 100 amp hour battery, you could run a device that draws 10 amps for 10 hours. This brings us to the topic of batteries and power.īatteries are measured in amp-hours. If you tried hooking your fridge up to your car battery with an inverter, you’d kill your battery in minutes. The fridge in your home, for example, runs off of 120v alternating current. This is the premise behind most refrigeration systems, whether it’s the fridge in your kitchen or your home’s air conditioning unit.Īs you might imagine, a compressor needs a lot of energy to do its work. In other words, a refrigerator isn’t really cooling the space within as much as it’s sucking the heat out of it. And as it does so, it literally sucks the warmth out of the surrounding area. As it runs through the tubing, it cools down to ambient temperature, which causes it to change back into a gas state. But it doesn’t remain in this liquid state. If you’ve ever put your hand on the side of a fridge and felt the warmth it produces, you felt the effects of a compressor turning a refrigerant from gas to liquid.Īs the refrigerant turns to liquid, it moves through a network of pipes and tubes that run through the walls of the fridge. Pressure does it too, and that’s where a compressor comes in.Ī compressor pressurizes refrigerant which, in turn, causes the gas to heat up. However, the temperature isn’t the only thing that causes this state change. At room temperature, it’s a gas, but when the temperature drops, it turns to liquid. ![]() In most refrigeration systems, there are three important parts: A compressor, a chemical refrigerant and the tubing required for the refrigerant to travel through.Ī refrigerant-typically freon-is the magic that makes good refrigeration possible. To understand what makes a good 12v fridge, it’s helpful to understand the basics of refrigeration.
