Recap: Best RV Power Converters


Factors to Consider when Purchasing a Power Converter

When you are purchasing an RV power converter, there are some factors that you need to keep in mind. Consider these factors when you are choosing your next unit.

Installation

Some RV power converters will need to be mounted while others can simply be set up in a corner, room, or even closet. While most RV converters will not require professional installation, some mounted RV converters may require this. If you do not feel comfortable in setting up your RV power converter yourself, then it is best to have a professional set it up for you.

Consider Your Power Needs

Older, single stage power converters do not have the ability to charge your batteries. There are some units that may also only be able to provide a limited amount of charge. More modern units are not only able to convert the power, but they can provide a charge to your battery as well. When you are considering your needs, you will notice that the different capabilities offered will play a role in the overall price of the unit.

Consider the Size of Your RV

Unsurprisingly, the larger your RV, and the more appliances you run, the larger you need your RV power converter to be. 12-volt power output ratings will typically require anywhere from 20 Amps to 100 Amps. If you find that your appliances are not operating to their capacity, then this is an indication you need a more powerful converter.

Protect Your Appliances

Installing your converter correctly and investing in a quality converter can keep your appliances and electronics from being damaged. Damage to your appliances might occur when the 12-volt DC is not smooth, resulting in “ripples” in the current. Consider this feature when you are looking for an RV power converter.

Price

Not all RV power converters are made alike. Whether you have a single stage converter or a three stage converter, you will find that the price point can be anywhere from $50.00 to $300 for an RV power converter.

When you are shopping around, the price should play a role in your selection, but you really need to look at the features the converter is able to provide you with. Specific features like noise-free cooling fans and surge and spike protection can be beneficial, but they will also drive up the price of the unit you are looking at.
