Mini fridges offer all sorts of storage, and some of them even come with medical oxygen concentrator inside as well. Unfortunately, you can’t power them with AA batteries. They require much more electricity, which is why you need to have a constant source from either the car battery or a solar power setup.
Let’s compare the two types of sources below.
Using A Car Battery To Charge A Mini Fridge
Every vehicle has a power source right under the hood. A car battery has tons of electricity (which is why they can keep a vehicle moving). The main concern that you need to be aware of if you decide to go this route is that you have to monitor your car’s battery.
We all know that running too many lights or other electronics from a car battery can deplete it quickly. Fortunately, most mini fridges that you’ll use for your van have a shutoff that prevents it from draining the battery too low. However, it’s still not good to constantly go through a full cycle.
To prevent these issues, you need to turn on the vehicle and run it for 15 to 20 minutes a few times throughout the day. When you start the car, it uses the alternator to charge the battery. This process keeps your battery charged, giving you all the power that you need to keep your Vehicle Refrigerator powered.
