Best RV Converter: Transforming Your RV Lifestyle

Wouldn’t it be nice if all appliances would work in a recreational vehicle by the simple fact of plugging them in? Unfortunately, this isn’t always the case. Some items run on AC (alternating current) power while others run on DC (direct current) power. In some instances, you’ll need to connect AC to DC power, and that’s where an RV power converter comes in.

In this article, we’ll tell you everything you need to know about choosing an excellent RV converter.

AC Power Converters: Buyer’s Guide

The electrical system in recreational vehicles is complicated and can become a headache if you aren’t at least an amateur electrician. With this being said, you don’t have to know everything about electricity to choose an excellent RV converter charger for your RV. Before jumping into what you should be looking for, let’s answer an important question.

What is a Camper Power Converter, and Do I Need One?

As briefly suggested in the introduction, an AC power converter will convert 120 volt AC down to 12 volt DC power. You need this conversion because most recreational vehicles have both AC and DC power systems.

The batteries, lights, fans, TVs, and other electronics requiring a small amount of power run from the DC power system. The appliances and electronic devices in your RV that draw a lot of energy, such as the refrigerator, air conditioner, heater, run from the AC electrical system.

So what does this mean regarding an RV converter charger?

Think of an RV converter as a way to transfer power from one medium to another. For example, city power is on an AC supply, but your recreational vehicle batteries are on DC power. The converter allows for AC power to charge your batteries and DC-powered devices, while simultaneously providing power to those AC-powered electronics in your camper.

In short, if you have an RV and plan to hook up to shore power for your power supply, then you need a power converter for your vehicle.

Other Converter Scenarios

Running Your RV Off of Shore Power

With the above being said, you can run everything in your RV from the batteries without a converter charger if you have an inverter to transform DC current to AC current. Still, you would only be able to do this temporarily. You’ll probably only be able to run the basics like lights and small electronic devices. Systems like the heat or the AC will drain your battery power quickly.

It’s much smarter to use a power supply converter charger to hook up to the campground pedestal at an RV park.


Using a generator for your power source is in some ways similar to hooking up to a power pedestal at an RV park, as it provides AC power and so you’ll need a power converter to use it. Some generators are inverter generators, but most likely you won’t find any with a built-in converter. Keep in mind that hooking up to the campground pedestal will provide more juice than generator power, so you may still want to hook up to shore power at some point.

Solar Power

If you have a modern power system in your RV that uses solar power, you’re in luck. You don’t necessarily have to have a converter because solar power is on DC power.

But before you ditch the travel trailer converter idea…

Solar power isn’t anywhere near as powerful a power source as hooking up to a campground pedestal. It’s also dependent on factors such as weather or environment. Solar power systems are designed to charge your RV batteries, not necessarily run your appliances and electronic devices. You may want to have an electricity converter charger handy in case you’re in a scenario where mains power is going to work better than solar energy.

Alternatively, there are DC-to-DC solar power RV converters that will increase the amount of energy that your solar panels collect. It also regulates the current so that it’s more consistent.

What You Should Look for in an RV Electrical Converter

Now you know for sure that you need a power converter, the next step is figuring out the best RV converter for your particular needs. Price plays a significant role, of course, but it shouldn’t be the only deciding factor. Other aspects you should consider are:

  • Amperage (Amps)
  • Battery Charging
  • Size and Weight
  • Safety Features


One of the most significant factors to consider when purchasing a travel trailer power converter is how many amps it is. Amps are the measurement for the current, which can be thought of as the rate that electricity flows through the RV converter. RV power converters come in a range of different amps, but in some cases, the lower-amp RV converter chargers may not be suitable.

This is because when hooking up to shore power for your power supply, you’ll have three-amp options: 50 amps, 30 amps, and 15-20 amps. At 15-20 amps, you’ll barely be able to run what you need in your recreational vehicle. Thirty amps is a decent amount, but if you have at least a 50-amp RV converter, you won’t have to pick and choose what to run at any one time.

Keep in mind that while 50-amp 12 volt DC converters can work in a 30-amp hookup, 30-amp converters can’t work in the 50 amp. This is another reason to go for a larger amp RV converter.

Battery Charging

Most travel trailer power converters will charge your RV batteries too, but you should be aware of the different types of RV converters & RV battery chargers available to buy.

The first type is a single-stage battery charger. These are designed to charge your batteries quickly. The downside is that they charge at one battery voltage (one rate), and can easily over-charge your batteries. This will lead to damage to your batteries down the line.

The second type is multi-stage battery charging. This type is sometimes called a smart RV converter charger. It charges in different stages (rates) to prevent over-charging and consequently battery damage, thus extending battery life. The most popular is a four-stage battery charger.

Size and Weight

Most RV converters are lightweight and small. The average weight ranges from five to ten pounds. The size can vary a little more than the weight. There isn’t a standard size for 12 volt power converters so if you have a space you plan to store it in your RV, you’ll want to measure up first.

Safety Features

As with any electronic device, there is potential for hazards like shocks or fires. Because of this, you should choose converter chargers that have built-in safety features. At a minimum, the power converter should have thermal/overheating protection. Other great safety features are reverse polarity protection and overload protection.

IOTA DLS-30 Engineering Power

Best 30 Amps

IOTA Engineering (DLS30 30 Amp Power Converter/Battery Charger

If you’re in the market for nothing stronger than a 30-amp power converter, the IOTA DLS-30 is an excellent choice. Although it may not perform at the same level as higher amp versions of the DLS-series, it performs well enough for someone who only needs 30 amps or less.

It’s a single-stage unit with 13.6 volts DC output. It’s compatible with the IOTA IQ4 smart charge controller to turn it into a multi-stage converter battery charger. We like the fact that it only uses 400 continuous watts so you can reserve even more power for the things you need the most.

The DLS-30 is like a “step-down” version, so it’s only about 80% efficient. Another thing to consider is that it only outputs 13.6 volts for the bulk stage, instead of the preferred 14.4, but it will still give your acid batteries a good, fast charge in this stage.

  • PROs

    • Can be used as a multi-stage battery charger
    • Has all four major protection systems
    • Quiet cooling fan operation
  • CONs

PowerMax makes excellent products, and the PM4-55 is no exception. Although it’s very similar to the PM3-55, the big difference is that it’s a four-stage, instead of a three-stage, charger. This is a high-quality, 55-amp power model that is simple to install and use. It’s an efficient, quiet piece of equipment that will still give enough power to run multiple appliances in your recreational vehicle including the air conditioner.

The PM4-55 has reverse polarity, overload, and thermal protection. It has a sturdy construction, so can handle a few bumps traveling on the road. It’s a little bigger and heavier than most, measuring 12.3 x 9.1 x 5 inches, and weighing 6.45 pounds. Not at all unmanageable but size may be an issue if it can’t fit into certain spaces.

There is however one apparent hiccup with this product. It’s advertised as a four-stage, but it only automatically adjusts to three stages. The last stage must be set manually using a digital voltmeter. This can be difficult, especially once the unit is installed.

  • PROs

    • Durable, rugged construction
    • Quiet operation of fan
    • Built-in smart charger for your batteries
  • CONs

    • Fourth-stage takes a manual adjustment
    • No low voltage protection

Bottom-Line: Despite the fourth-stage adjustment inconvenience, the PM4-55 is a great, affordable product that performs well.
