RV Converter Chargers – Ultimate Buyer’s Guide

| Last Updated: February 1, 2023

Looking for an RV Converter Charger? They're critical part of the RV set up even if they don't spring to the front of your mind while planning a trip.

Traveling in an RV has its adventures, fun, and excitement, and thanks to the appliances available, road trips are much easier than they have ever been. A converter charger for your RV is one of these appliances that makes life easier.

A converter charger takes AC voltage from electrical lines and turns it into DC voltage so you can use it with your battery 24/7. This device also keeps your battery and backup batteries charged and ready for your next adventure, making them a very important part of your set up.

Usually, RVs have two independent electrical systems: a 120-volt AC, which gives electricity to high-wattage and high-power consumption appliances, and the other is the electrical system’s low-voltage portion which provides 12V DC.

An RV converter charger allow you to run appliances with shore power while simultaneously charging your battery. They provide a smooth and uniform DC voltage that's more than enough for operating 12-volt appliances. You can also use it for televisions, refrigerators, generators, and fans.

But of course, not all converter chargers were created equally. Fear not, as we have a review below of some the best models on the market, saving you time and effort so you can concentrate on the more important things in life.

What to Look For When Buying an RV Converter Charger

You can't just simply go to a shop and purchase an RV converter charger without having some facts in mind. There are a lot of things that you need to consider before purchasing anything. Here are some things to keep in mind.

Chemistry of the Battery

One of the most important aspects is the type of chemistry on which the battery depends. Many converter charges contain one type of battery chemistry. If you are operating a lead-acid battery, then you should avoid the converters for AGM and lithium-ion batteries. So before buying a charger, do consider the kind of batteries you own.

Charging Requirement

A user needs to be clear about the speed of charging that they are looking for. Chargers that have high watts can charge a battery in a shorter time, but it can also pressurize the battery. This can cause an explosive reaction. Thus, you need to purchase a battery that can charge in a faster and safer speed.


The price at which the batteries are available is also a very important factor. You need to consider your budget. You should purchase one which offers maximum performance and is inexpensive too.

Types of RV Converter Chargers

There are a lot of RV chargers available in the market. But every converter has its features, price, specifications, and uses. You need to select a charger that offers maximum power at an affordable rate. The different types include:

Smart Converter

Smart converters uses stages to power your battery to ensure your RV battery does not get overcharged but receives sufficient power to operate your appliances. This means at the beginning stages, the battery is being charged at a faster rate and as it approaches a full charge, the charger slows until it reaches 100%. 

Inverter Chargers

This is the best of both worlds. An inverter/charger is able to convert AC power into DC to power the RV and appliances, while also converting the DC current into AC to allow 120-volt appliances to operate normally. 

High Output Converter

This type of converter is able to handle large power loads and charge multiple batteries at the same time. This is also useful in extreme temperatures where lower output converters may struggle to provide sufficient juice to keep your RV operational.

How to Install RV Converter Charger

Installing an RV converter charger is not as difficult as you are thinking. But you need to keep in mind that installing anything requires some instructions. To help you install an RV charger, here are some easy steps. Follow them and install your converter.

  1. First of all, if you have any old charger, you will need to use a wrench to disconnect the negative terminal of the battery wire. Turn off the shore power and disconnect it. Remove the older converter by unscrewing and unwiring.

  2. Double check to make sure the power is not on in the RV. Remove circuit breakers, cords, and power supply from the generator.

  3. Using a wrench, disconnect the ground cable of the battery.

  4. Put the converter charger in its right place. Ensure the area has proper ventilation for heat dissipation. Some converters have built-in fans, so you need to select a large place so that it can work without any sort of hindrance.

  5. You need to connect the wires according to the instructions present in the manual. Do read the instructions carefully before joining the wires. Most connections will be clearly labeled to reduce confusion and provide guidance for proper connections.

  6. Afterward, connect the negative terminal again to the battery. Plug-in the umbilical cord of RV to the source of shore power. Test the output using a multimeter, and it is ready to use.

For clear instructions of the whole process, check out the following video:


To put it simply, these RV converter charges are an excellent and necessary tool for RVs. They are useful in several ways, allowing you to charge a battery, using the RV's lighting, and giving power to various appliances. These are important anytime you want to connect to a land-based electrical source to power and charge your RV. 

People Also Ask

There might be several questions that might confuse you regarding RV converter chargers. You can’t buy a charger with these queries in your mind. We have provided answers to some of the most frequently asked questions.

How Does a Converter Work in an RV?

The main purpose of the converter in an RV is to convert the AC voltage into DC voltage whenever you are plugged in to an electrical source. When you connect the RV with an electrical source or the onboard generator, the converter will convert the AC voltage (120 Volts) into DC voltage (12 Volts). You can use this voltage for operating all 12-volt devices in the RV.

What is the Difference Between an RV Inverter and Converter?

The main difference between an RV inverter and converter is that an inverter converts 12 Volt DC voltage into a 110 Volt AC voltage in an RV. While an RV converter transforms a 110 Volt AC voltage into 12 Volt DC voltage. Therefore, an inverter allows appliances that plug into outlets to run on your RV battery power, while a converter allows electrical current from land lines to be used and stored by your RV battery. 

How to Test RV Converter/Charger

First, you need to test the 120 Volts AC terminals using the voltage meter. This will tell you whether the power is going to the RV converter charger or not. If there is no power, then check the fuse across the terminals. The reading should be at least 120 volts. Then you need to check the DC voltage across the terminals of the coach battery. Use a voltmeter for this. The approximate output should be 14 volts. If it shows a wrong reading, then there might be a problem with the converter charger.

How Do You Know if Your RV Converter is Bad?

Different signs will be visible when your RV converter goes bad. You will start noticing some warning signs like the lights in your RV will start dimming. Similarly, electronic appliances will cause some problems too. The refrigerator will not maintain its temperature, and the power outlets won’t work. The most serious issue will be that the RV's battery will not maintain its charge and will drain at a faster speed.

Will an RV Converter Work Without a Battery?

No, an RV converter won’t work without a battery. Although some converters do not require any battery, RVs do need a battery for their converters. Without a battery in your RV, you won’t be able to use devices like alarms and LP detectors. You also won't have any backup in case of a power shutdown.

How Many Volts Should an RV Converter Put Out?

Your RV requires more power and voltage than other vehicles. To achieve this high power, we use a converter in an RV to transform the 110 Volts of AC electricity into 12 Volts of DC electricity. This conversion will help you in operating your 12V appliances.
