Will An RV Fridge Run Off Battery?

The summer break is already here, and a vacation is already calling out your name. The kids are already asking about the road trip or that camping you had promised them earlier. After all, spending some time with the people you love does matter a lot. Outdoor activities help one relax while boosting the bond between you and the kids.

However, we both understand how stressing it can be, especially the preparations. When using your recreational vehicle, there are many things you have to check out.

Unless you don’t enjoy a cold drink or fresh food, having a fridge is non-negotiable for any RV.

When the idea about cold drinks comes around, many people are always asking, ‘will RV fridge run off a battery?’ Yes, it can run off your battery now that it needs the power to keep everything fresh. However, the time it takes to drain your battery depends on many factors, among them the type of fridge you have in the car.

For instance, you can’t bring your home fridge in the RV and expect it to be kind to the battery. As usual, it will drain the charge in no time because it’s not designed for that setting.

As you are aware, an RV fridge runs on AC while the battery provides DC. Therefore, you will still need an inverter to get the job done. When used alone, the DC can serve your fridge for about three to eight hours. But, when used alternatively with propane, for example, or electricity, the same battery can run for even weeks.

Which Fridge is Suitable for My RV?

When it comes to energy consumption, they are efficient, and that means that your RV’s battery can power them for a specific time.

Currently, you can find RV refrigerators that can run on batteries, inverters, LPG, and even propane gas. With this many options, it means that you won’t have to worry much about your battery draining charge. You can choose between the four options based on the situation at hand.
