Best 6 RV Power Inverters For RVs And Travel Trailers

After researching 6 products, we found the AIMS Power 3,000-Watt model to be the best power inverter for RVs and travel trailers.

When we first got serious about RVing, we didn’t realize that we couldn’t plug my electronic devices right into the camper’s outlets. To do this, I needed an RV power inverter to redirect the current.

How does this work? Put simply, the RV inverter takes the current from the battery of the travel trailer, then converts it to an alternating current. That way, you know it’s safe to plug in your devices without worrying about them getting fried.

Buying Guide

When you’re shopping for an RV power inverter, you want to choose carefully. Here are some of the key features and benefits to be aware of before you begin your search.

Features To Look For


There are several different types of RV inverter to choose from. Here’s a brief rundown on each one.

Sine Wave
This version is quite popular, particularly with utility companies. Most appliances and equipment can be used with a sine wave RV inverter, so it offers peace of mind in addition to being easy to find. In fact, some appliances, such as microwaves, will only produce their full output with this type of RV power inverter.

Be forewarned that this is the most expensive type of inverter on our list. Its positive qualities help to make it worth the investment, but you can expect to spend twice as much on a sine wave model than you would for another type.

Modified Sine Wave
A modified sine wave RV power inverter uses a waveform current, which makes it compatible with most electronic equipment.

One unfortunate side effect, however, is that it may cause a reduction in efficiency for the attached devices. This means that your appliance’s motors might consume more energy to make up the difference. In point of fact, this type of RV inverter can cannibalize up to 20 percent more energy than a sine wave device.

Moreover, modified sine wave inverters are generally louder than the competition. While the difference is slight, it’s worth mentioning if you’re looking specifically for a quiet power inverter for your travel trailer.

Square Wave
This is the least popular type of inverter listed here, but it’s also the least expensive. It’s not as capable as the others, as its usefulness is limited to simple tools with universal motors. You’re far more likely to find a sine wave or modified sine wave inverter than a square wave model—and you’ll get more use out of it, too.


Look for the most efficient model you can find—that is, one that won’t cause a noticeable increase in your energy consumption. If your power inverter isn’t energy efficient, it won’t be worth the cost.


You’ll need to familiarize yourself with two important terms when deciding what size inverter to buy: surge and wattage.

The surge, or peak power, is the maximum amount of energy that the inverter can supply. It can run on the surge level for only a short period—usually no more than 15-20 minutes. Devices with electric motors often require a high startup surge, so keep this in mind when deciding.

The terms usual and typical refer to the energy that’s fed continuously into the devices from the power inverter. As such, it’s far lower than the surge. It may also be called the continuous rating.


You should also familiarize yourself with the inverter’s input and output voltage. These will help you determine whether the unit is compatible with your RV.

In order to work, the RV power inverter needs to be in line with the battery that’s providing it with its energy source. Therefore, a 12V battery would work with a 12V DC RV inverter.

The AC, or output voltage, is another factor to consider. If your devices were purchased in the US, Canada, or Mexico, they probably use 120V AC power. Devices from other parts of the world, meanwhile, might use 220V to 250V AC.


Using an RV power inverter can be beneficial in many ways. For one thing, they’re more efficient than gas-powered generators. This means you can enjoy all the comforts of home when you’re traveling in your RV. It’s especially true of pure sine wave inverters, which operate at a higher level than their modified sine wave counterparts.

There’s also no need to buy gasoline or any other type of fuel when you use this type of inverter. It harnesses the energy from your RV’s existing battery, which means less hassle. It also makes less of a mess and frees up valuable space in your rig.

Finally, RV inverters make very little noise. When you compare them to generators, which can be loud enough to wake the entire campground, this is a great perk.

In Conclusion

With the right RV power inverter, you can relax and enjoy your camping trip knowing that you’ll have plenty of energy to fuel your appliances. Once you’ve had a chance to learn about the different types, it will be easy to choose one that works for you.

Our top pick from AIMS covers all the bases, which is why we think you’ll be pleased with it. Easy to install, even simpler to use, it makes life on the road a breeze, even if you have multiple appliances to hook up.

Good luck, and happy camping!
