The Best RV Converter Chargers (Review) in 2020

Peter Wade

It’s common knowledge among RVers nowadays that batteries in recreational vehicles only take direct current (DC) power and shore power is alternating current (AC).

Because of that, RVing enthusiasts that wish to tap into shore power to charge batteries must keep power converters onboard.

As the name implies, converters convert AC power to DC power which would allow people to charge the batteries on their rigs using shore power.

Though lots of recreational vehicles come with built-in power converters, such converters still leave a lot to be desired.

In the case that you seek to replace the stock converter of your ride with the best RV converter, this article could help you out.

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.

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.

Why It’s An Editor’s Choice:

Flexible and versatile, WFCO WF-9855 is known among RVers as a solid RV converter charger that never fails to please.

Being FCC Class B-compliant, the converter made by WFCO ensures that televisions, radios and other electronics in your RV can work free of interference.

Moreover, unlike the average converters for recreational vehicles, WF-9855 is engineered to distribute clean power without filtering from a battery.

Hence, WFCO WF-9855 gives a good account of itself in a wide range of settings.

In use, the automatic three-stage charging (float, absorption and bulk) of WF-9855 speedily charge batteries and extend their lifetime.

Additionally, the camper power converter of WFCO operates in a quiet manner as its cooling fan only turns on when needed.

That is why in the case that you prefer to have a tranquil outdoor experience, you should think about adding WFCO WF-9855 to your shortlist.

For safety, WF-9855 has electronic current limiting so it’s going to shut down if overloads and short-circuits occur.

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.

Why We Love It:

Boasting a combination of load regulation and switch-mode technology, DLS-45 of IOTA Engineering simultaneously optimizes the charging time and preserves the integrity of batteries.

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.

How To Select The Best RV Converter

Overall, due to differences in preferences, the best RV converter of many could appear to be mediocre to the rest.

Nevertheless, if you wish to get your money’s worth, keep the criteria down below in mind at all times.

power converters for rv

Output

As the power coming out of your converter determines the time it takes to fully charge your batteries, you should pay special attention to output.

By taking into account the scale of your battery bank and the appliances on your rig, you may deduce the ideal output for your converter.

If you happen to own a rather typical setup, you could settle for standard models.

However, in the case that you need plenty of power and don’t like to wait too long, it’s strongly recommended that you pick up a high-output converter.  

Space

In ordinary recreational vehicles, space is a luxury so before grabbing a particular converter, you have to make sure that your rig can accommodate it.

As an RVer, the last thing you want to do is to spend big bucks on an oversized power converter that gobbles up available space.

Therefore, it’s widely advised that you plan out the location of the converter in your RV and decide accordingly.

That would help you narrow down the number of power converters that you must evaluate.

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.

Safety

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.

High-quality travel trailer power converters on the market nowadays tend to pack protections against overload, overheat and similar threats.

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.
