Recap: Best RV Power Converters

Buying a Power Converter Charger: What to Look For

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.

Types of Power Converters

There are a few different types and setups of power converters and chargers to choose from.

  • High-output converter – if you need a lot of power, make sure to get a model with up to 80-90 amps.
  • Multistage converter – this type of converter typically has built-in equalization, which is great for charging a bunch of different types of batteries.

Outside of these two options, there are a lot of converters that come with deck mounts and distribution panels that you can screw to a sidewall or the floor of your RV.


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 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 be a full-time battery charger. 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. Bottom line, a power converter should not replace shore power or other means for charging your RV battery.

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 a good unit.


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.

Final Thoughts

Whether you need to charge your battery, carry extra power, or boot up your appliances, a power converter is a must when you are on the road. What do you find to be the most beneficial feature of an RV power converter? Shoot us an email and let us know.

Frequently Asked Questions

What Size Power Converter Do I Need For My RV?

The size you choose depends on the size of your RV and the appliances you use. If you have a bunch of high draw devices such as a fridge and coffee makers, you might need a larger converter. You can buy a larger converter than you need so that you can add more devices to your RV if you need to, or if you decide to get a larger RV.

How Many Watts Does An RV Converter Use?

As with size, the types of devices that you have plugged in determine the draw of your inverter. You AC will be the largest draw of wattage (up to 2000 with some units). Take into account what you are plugging in and what you want to power all the time before you buy a converter.

Where Is The Power Converter In My RV?

Most power converters are located in the fuze box area of your RV.
