RV Power Converter Basics

1. What is an RV Converter?

If you owned an RV already, you probably have a converter. So what do RV converters do?

Typically, an RV converter is an electrical equipment designed to convert Alternating Current (AC) into Direct Current (DC) – they take a higher voltage and convert it down to a lower voltage. So, its primary function is to convert household power (AC) to battery power (DC). Motorhomes usually have a 12V DC circuit along with some branch circuits.

So in the case of most RVs, the converters are gonna take 115 volt or 120 volt AC power in like from your shore power for example and convert it down to 12 volt DC power. This power is ideal for battery storage and also comes in handy when there is no shore power supply. Based on the type of DC equipment in RV and the total number of batteries, users should choose the power converter.

The power converter also acts as a battery charger to maintain your coach batteries, when you’re plugged into shore power, the converter is charging your battery back up.

Please note that you will only need an RV converter if you want to charge the RV batteries when you are using the onboard generator or after plugging them into shore power.

2. What Are the Benefits of an RV Converter?

Whether looking for a new installation or a replacement, users must know the benefits they will get after installing a camper converter.

A power converter for RV.

Protection against Battery Draining

A converter for the motorhome will keep the batteries charged, at least partially. Therefore, there will be no chance of draining. No matter what is the power source, the converter unit can charge the onboard cells. So, users have to choose a converter for their RV that can work on any available power.

Even Power Distribution

An RV converter guarantees even distribution of power, devoid of any overload, high temperature, over current, and reverse polarity. As a result, there will be no chance of damage because of electricity fluctuations. Many smart converters also come with a feature that will automatically shut down the power whenever it senses any irregularity.

Seamless Power Supply

The power converter charges the batteries continuously, so users do not face any interruption while using the appliances onboard. Some converters are also capable of recharging car batteries, vehicle batteries, and electronic devices.

Long-Lasting Battery

By keeping the batteries charged all the time and by never letting them drain completely, a converter extends the battery life.

Safety of Electrical Appliances

A converter helps to keep the electrical appliances safe by preventing any damage. You do not have to spend any extra money on the repair costs in that scenario. The RV appliances will also get adequate power for running optimally.

Types of RV Converter Chargers

Motorhome converter manufacturers produce various types of converters that address the varying power consumption requirements. Learning about all the categories will help users decide which one is the ideal converter for their RV vehicle.

Multistage Converter

If there is a need for a converter to charge different batteries, including lead-acid batteries, this converter is here for you. In the early days, there were fixed-voltage converters that had a single-stage design. But the latest converters of this type come with an advanced technology that supports the contemporary vehicle models. Moreover, it offers a DC voltage output as well as efficient charging time.

High Output Converter

As the name suggests, this type of converter is suitable for people who have high power consumption needs. It is not something that will crash and leave you stranded during long trips. Instead, this high-performance converter can deliver up to 80A or 90A. While meeting the power demands of the trailer while traveling, it also offers durable service. It is capable of charging and preserving the batteries simultaneously. Therefore, this converter comes in handy when users need constant cooling.

Deck Mount Converter

It is evident from its name that users can mount this converter unit anywhere as they wish. You can mount it inside the cabin, under any of the seats, or in any other place that has facilities for redirecting the power supply.

Distribution Panel Converter

Experts suggest this converter to the passionate travelers who want to upgrade their factory unit. A distribution panel converter is a perfect replacement for any old models, and users can also install them in the same spot.

These converters come with a sizable panel. They considerably decrease energy loss, do not produce any noise, and contain a sizable panel. Its battery charging ability is more efficient than the older models.

RV Converter vs RV Inverter: A Brief Comparison

Trailer users may be familiar with the RV inverter. Since the converter and the inverter have almost similar names, people often get confused about their functions. There is a list of differences between a converter and inverter for RV.

Check the following table for a better understanding:

 RV InverterRV Converter
DefinitionIt is a piece of electrical equipment that can convert the direct current (DC) into alternating current (AC).This electrical equipment turns the voltage from AC (alternating current) to DC (direct current).
TypesMainly 5 types are available:
- Pure Sine Wave power inverter
- Modified Sine Wave power inverter
- Square wave power inverter
- Portable power inverter
- Heavy-duty power inverter
Four types are available:
- Multistage Converter
- High Output Converter
- Deck Mount Converter
- Distribution Panel Converter
ApplicationsAn RV inverter converts the DC electricity that solar panels, fuel cells, or batteries generate to AC. When a UPS is in use, an inverter supplies AC power when the power is unavailable.A converter mainly converts AC to DC. It also identifies amplitude modulated radio signals. For welding purposes, converters provide polarized voltage.
LimitationsIt is not the best option for motor and inductive AC. When low batteries generate poor waves, it can harm sensitive electronic devices.Its current overload capacity is not impressive. To have automatic regulators of good quality, it will cost more than mechanical regulators.

Top-Rated Power Converters For RVs

RVers tend to have contrasting ideas about the best RV converter but if you need a couple of recommendations, it’s suggested that you give the following models a look.

1. Powermax PM3 – Best Of The Best

Why This Is The Best:

With state-of-the-art three-stage charging technology, Powermax PM3 could provide clean DC power to many types of batteries in plenty of conditions.

In addition to that, depending on the system requirements, it’s also possible to change the output mode of PM3.

As a result, the Powermax converter is usually considered to be the best RV converter available for purchase on the market once it comes to adaptability.

Possessing a rugged construction, PM3 is able to handle shocks and vibrations as well.

Regarding installation, the converter from Powermax is simple to set up so you don’t have to spend too much time to get it working.

Since it has an integrated cooling fan, PM3 dissipates heat at a rather quick rate which permits it to maintain consistent operation as temperatures climb.

Furthermore, Powermax PM3 boasts reverse polarity, overload and thermal protection.

Because of that, the Powermax power converter is held in high esteem by RVers that like to play it safe.

As for affordability, PM3 of Powermax is sold at a price that matches the shopping budget of most RVing enthusiasts.

To reassure RVers, Powermax willingly backs its power converter with a decent two-year warranty. 

So if your Powermax converter fails due to manufacturing defects within the warranty period, you may claim a free replacement.

I installed this in my RV to replace my factory converter. The factory converters are loud and inefficient. I installed this unit in my front cargo compartment and ran new 6 gauge wires directly to my batteries. As other reviews have stated the fan speed is not variable, but it does only turn on when needed. For example, my factory converter runs the fan at full speed when pushing 8 amps into the batteries, this unit can do over 8 amps without the fan running at all. Also, in my initial testing this thing pushed 3x the amps into the batteries as the factory unit. Strongly recommend this unit for mounting in a cargo area. This will allow my to charge the batteries much more quickly when dry camping and using the generator.

Since it packs a microprocessor-controlled system that automatically selects charging voltage and operating mode based on battery usage, PD9260C could be put to good use in multiple applications.

An accessory port is included so users have the option of pairing the Progressive Dynamics converter with a status remote pendant for manual mode selection.  

Featuring a current limit, Progressive Dynamics PD9260C promptly reduces the power output if it notices that the maximum capacity of the batteries is reached.

Aside from that, thanks to the low voltage protection, the converter made by Progressive Dynamics keeps appliances from being damaged by irregularities in the voltage. 

PD9260C of Progressive Dynamics has built-in reverse polarity protection as well so it’s capable of preventing damages caused by improper battery insertion.

Overall, if you care about batteries and appliances on your rig, PD9260C is the best RV converter for you.

In terms of heat dissipation, the RV power converter charger from Progressive Dynamics comes with a variable speed intelligent cooling fan that activates on demand.

During low-demand use and sleeping hours, the fan of PD9260C would run at slow speeds to keep the noise down and minimize disturbance.

Holy crap! That’s what went through my mind as soon as I turned this thing on, right after installing it. My old 45amp converter was barely putting out 12V. When I had my old one, every time I turned on a light, or water pump, or anything 12V I could see the lights getting dimmer and dimmer. Taking a shower was like showering in a disco, because of the strobe light effect. Anyhow, after turning this baby on, ALL of my 12V system works like it should. I can turn on every single light, run the furnace, turn the water spouts on and even bump my 10″ sub with 300watt Alpine amplifier, all without a single noticeable change in a single light bulb. Everything is bright, and my lights don’t pulsate to the bass from the subwoofer anymore. It’s brand new right now, and works great. If it lasts me at least 5 years I’ll be happy. If it lasts 10 years I will be pleasantly pleased.

Needless to say, for RVers that want to install a power converter on the go, WF-9855 is undoubtedly the best RV converter money can buy.

The WFCO Converter exceeded my expectations. The voltage output under various load conditions was carefully measured. Once the storage batteries were fully charged on the RV, the converter automatically dropped to a trickle charge to maintain the batteries in a static condition. The unit was easy to install and is very quiet. Each time the unit is turned on the fan momentarily runs regardless of load for the purpose of proving fan operation. My old converter tended to boil the batteries with an excessive charge during non-occupancy periods. That is no longer an issue with the new converter.

The power converter from IOTA Engineering is set to supply maximum current to the batteries in an appropriate period of time to reduce stress caused by the heating of cells.

As the batteries on recreational vehicles approach full power, DLS-45 would automatically drop the charging current and move to float charge to tackle self-discharge.

Interestingly, the RV 12-volt converter made by IOTA Engineering has a unique dual voltage jack that allows two-step charging.

By plugging the accompanying plug into the jack, DLS-45 could deliver an increased “quick-charge” for swift recharging of batteries.

Also, the jack facilitates the installation of the IQ4 smart controller that offers RVing enthusiasts four-stage “smart-charge” control.

It’s worth noting that the IQ4 smart controller is optional so if you wish to use it, you have to make a separate purchase.

Following the trend, IOTA Engineering DLS-45 possesses current limit and thermal/overload protection so it’s quite safe to use.

The presence of reverse polarity fuse protection means you have nothing to worry if you mess up the battery insertion.

I replaced an IOTA charger with this, the latest model of the same thing, and I am VERY happy with the purchase. It went in and functions exactly as specified, and with the separate IQ controller plug in device, I have the option of changing over to LiPo with just an IQ controller change in future. This charger with the controller keeps my batteries at the perfect level, eliminating the worry of overcharging when we have to leave it plugged in for a long stay at the full hookup campsites.

There are a pair of 30 amp fuses that will blow if you accidentally reverse wire your battery, instead of frying the unit’s internals, as well. (Sure, we all think: “I’d never do that”, …until it happens.)

Note that my previous charger was stock equipment on a 2003 RV, and when I called, the folks at IOTA said: don’t plan on using these chargers for more than fifteen years. The capacitors are consumable internal parts that start to go bad some few years after the ten year mark. I thought about it, and its not unreasonable to need to replace this kind of device every 15 years. Bring it on.

Choose the converter carefully.

When users plan to buy a power converter for their travel trailer, they will come across a variety of choices. Therefore, it is imperative to conduct in-depth research before finding out which is the best RV power converter. These are the points users have to consider before purchasing a converter for a trailer.

Power Capacity

While choosing the best converter for RV, capacity is the most crucial criteria. An RV converter that has the right capacity for the motorhome is the best for you. But an increase in load means an increase in weight and size. At the same time, the price of that converter will be higher.

Hence, it is imperative to search for a converter that can produce the total required wattage for all the appliances of RV without taking much space or putting a load on RV in terms of weight.

Power Level

Converter power level is another point users need to keep in mind while choosing the best converter. The power handling ability will make sure that the operations of onboard electronics are going on safely without any interruption.

To assure safety, choose a converter that can handle a minimum of 10 to 20 percent more wattage that all the devices of your RV will use in total. For example, if someone is planning to get an electronic device that takes 1,400 watts, one must choose a converter that can handle a minimum of 1,600 watts.

Compatibility with Battery

The principal task of a travel trailer power converter is to charge the batteries, so users need to keep a sharp eye on the type of battery charger and converter they want to buy.

Converters that come with a single-stage battery charger are capable of quickly charging the travel trailer batteries. But at the same time, it can overcharge your batteries and charge the battery at one rate. In the long run, it can also damage the battery.

Some converters have a multi-stage battery charging facility. Another name of these converters is smart RV converter charger. This converter type offers different stages of charging to prevent overcharging. Consequently, it extends battery life by putting a stop to the battery damage. The four-stage battery charger is the most popular one in this category.

Size and Weight

The average weight of most trailer converters range from 5 to 10 pounds. However, there is no standard size for these converters. Still, it is better to measure the storage space before purchasing to avoid any awkward situation later.

Safety Features

Once it comes to electricity, it’s impossible to be too careful so prior to committing to a purchase, you should assess the safety features. Like every other electronic device, RV converters also come with the risk of shocks or fires. So, always choose converters that contain maximum built-in safety features. At least it should have thermal/overheating protection. Its several essential features are reverse polarity protection and overload protection.

Noise Level

Lots of power converters for RV, especially ones that come with built-in cooling fans, emit sounds in use but some work quieter than others. Since it’s going to be tough to enjoy yourself next to a loud converter, it’s essential that you give noise level some thoughts.

To get a general idea of how noisy a model could be, you should take a look at the reviews written by fellow RVing enthusiasts. If you see too many negative remarks about the noise, it’s best that you move on to other converters.

Ease Of Installation

You always have the option of hiring professionals to install the converter in your stead. That being said, if you prefer to cut down unnecessary expenses, you need to choose a model that you can set up on your own.

To rate the installation difficulty of a model, all you have to do is to read the owner’s manual. If you have questions about the installation, don’t hesitate to get in touch with the manufacturer for credible answers.


The last point to consider before getting the best RV converter is the one that offers the best service within the budget range. To get the best quality RV battery charger converter, users need to spend more money.

While setting up a power converter for RV, it’s best that you refer to the owner’s manual instead of improvising on the spot.

However, if you need some general guidance, follow these steps:

Step 1: Disconnect shore power

To be on the safe side, it’s essential that you disconnect your rig from shore power prior to installation.

Don’t bother throwing switches, removing circuit breakers and alike, you should just remove the umbilical cord from its outlet.

Step 2: Disconnect the battery’s ground cable

Once the umbilical cord is out of the way, you need to move on to the battery’s ground cable. To pull out that cable, you must use a wrench.

Step 3: Position the converter

RV power converters often feature protruding flared panels on the sides for attachment so you have to be thorough while orienting your converter.

Converters generate lots of heat too, thus, it’s key that you put your converter where the heat easily dissipates. 

Besides that, if your converter possesses an integrated cooling fan, its location needs to allow the fan to function unobstructed.

When everything seems satisfactory, you could secure your power converter.

Step 4: Do the wirings

After you place your converter in a suitable spot, you need to do the wirings.

Most modern-day converters for RV have clearly-marked terminals so you should have an easy time with the wires.

Step 5: Restore the negative connection

Reconnect the battery’s ground cable and that’s it.

The only thing left to do is to plug the umbilical cord of your ride into shore power and then see how things turn out.

  1. WFCO appears to be working well after the install. The install itself is very simple and straight forward. This product is completely RF quiet, which was important to me since I operate sensitive radios for long distance communication in the RV. This is the second WFCO product I have used. The previous one started giving signs of failure after about 5 years on the job operating on a daily basis 24/7. The first one was still working but started making a loud hissing noise. That was a sign that it was time to put it out to pasture and avoid a complete failure at the least opportune time. If this one lasts another 5 years, I’ll feel like I got my money’s worth…again.
