RV power converters are essential components for any recreational vehicle. These devices convert the 120-volt AC power supplied by campground or household electrical systems into 12-volt DC power needed to run lights, appliances, and other electronics in an RV. They also help charge the RV's battery when connected to shore power. RV power converters come in various sizes and designs, ranging from basic models to more sophisticated ones with multi-stage charging capabilities and noise-reducing features. Choosing the right power converter for an RV can ensure a smooth and hassle-free camping experience.

  • Quick connect harness

  • Clear instructions
  • Reliable voltage reduction
  • Compact design

What We Don't Like

  • Occasional wiring mismatch
  • Rare early failure

What Customers Say

"I really appreciate the quick-connect harness and the one-wire hookup to the key switch, which eliminates the need for a separate on/off switch. The installation was straightforward, and I’m using it to power the lights in my golf cart with no problems so far. If I ever need to swap it out, the harness makes that simple."

"The instructions were clear and easy to follow, making the install process easy for me. It worked right out of the box, just as advertised. I used it during my lithium battery upgrade for a 2009 Club Car Precedent, and it was definitely worth the investment."

"The product looks well made and the wiring harness seemed solid, but unfortunately, my unit lasted less than 10 hours during initial testing with a lithium battery. I only got 3.4 volts output, which thankfully didn’t damage my new LED lights. This was just a trial, so I’m giving it a low rating based on my experience."

Frequently Asked Questions (FAQs)

1. What happens when the RV converter goes bad?

When the RV converter goes bad, you may experience abnormal flickering or dimming of lights in and around the RV. Additionally, if the onboard batteries can't hold a charge, the issue could be either the battery or the converter.

2. What is a power converter for in an RV?

The RV power converter's main function is to convert 120 volts AC from an electrical source, such as shore power or an onboard generator, into 12 volts DC. This converted power is then used to supply electricity to all the 12-volt appliances and accessories in the RV.

3. Can I use my RV without a converter?

Even if your RV is connected to shore power or a generator, you still need a converter. It is necessary to power the 12-volt DC components in your RV and to allow your batteries to charge properly.

4. How do I know what size converter I need for my RV?

To determine the size of the converter you need for your RV, you should add up the total amperage of all the 12-volt appliances, lights, jacks, slideouts, and other components. This will help you determine the appropriate size converter for your RV.

5. Does the converter in an RV run all the time?

The converter in an RV may run continuously if the batteries need to be charged or if there is a high demand for power in the RV. The converter's fan may also stay on to dissipate heat generated during the charging process.

6. How much does it cost to replace an RV converter?

The cost of replacing an RV converter can vary between $150 to $1,600, depending on the amperage and complexity of the converter. For most RVs, the cost is typically above $400. It is recommended to have a professional technician replace the converter due to the complexity of the procedure.

7. How long do RV power converters last?

Modern electronic converter/chargers in RVs are designed to be durable and can last for many years without maintenance. However, issues can still arise. If you suspect that your converter is no longer charging, troubleshooting tips should be followed to identify and fix the problem.

8. Does an RV converter charge the house batteries?

Yes, an RV converter can charge the house batteries. It uses power from the RV's generator or shore power to recharge the house batteries while it is running.

9. Can I use a battery charger instead of a converter?

While some DC-DC Converters can be adjusted to provide a 'float' charging voltage for battery maintenance, it is generally recommended to use a dedicated battery charger instead of a converter for optimal charging performance.
