Frequently Asked Questions (FAQ)

What is the best RV power converter?

Beware of knock-offs!

This is our final and most important suggestion: Read reviews, ask around, and find out which brands of power inverters are most reliable. Make sure that the power inverter you buy is from an established brand and reputable vendor.

Ultimately, when shopping for the best power inverter for your RV, your biggest concerns should be reliability, wattage, amperage, build quality, and warranty. Your second biggest concern should be ease of finding a replacement if your power supply is damaged.

How do you know if your RV converter is bad?

For the most part, if you’re using your RV and the batteries look like they’ve lost some charge you can pretty much rule out the converter as the culprit. When an RV converter is bad, it usually gives very little warning before failing. Most RVs are equipped with fuses to protect the converter and the wiring, so if you have any abnormal issues with your electronics you have to check those fuses first.

Perhaps the best way to know if your converter is bad is to just plug something in and see what happens. Feel free to do so. You can try charging your phone in the car, turn on the lights, turn on the TV. Just start plugging in and unplugging different things to see how bad it is.

What happens when the RV converter goes bad?

Unfortunately this isn't something we thought could happen, however on a long drive we recently discovered that our Converter/Battery Charger had failed. Being a retired Navy guy, I don't take these things lightly. I immediately noticed the problem and called the manufacturer for a replacement.

Because of this, the discussion on RV converters has come posting most frequently on the forums.

How big of a converter do I need?

If you’re just using your RV’s converter for your cabin or a few small things, you won’t need to worry about its size. You can get by with a small 1200W unit. But if you plan to do more, it’s probably best to go with a unit that has a higher capacity. You’ll have to decide what you are willing to spend and what you need.

Conclusion

The challenge that you have will always involve the question do you want to buy a cheap, unreliable product that might not even last long enough to see a year or two out? Or do you want to go for the more reliable products that are priced a little higher? Both have their advantages and disadvantages. The second option you have will always include the reliable RV converter that offers a long term investment and is a little expensive. It is worth buying these products. The first option will include the cheaper, unreliable products that are turned out to be waste of money.
