I have good memories of taking family vacations to Branson, Missouri, with my grandfather. We’d go camping and on road trips to the lake. But there were two resources my grandfather would manage stricter than an accountant: water and electricity. So the best RV generator was a must.

If you’re planning an RV excursion, it really isn’t feasible to go on your trip without the best RV generator. You don’t want to get stranded without electricity, plain and simple. If you do, your whole trip could be ruined.

On the surface, you may think the best RV generator is only helpful for powering amenities like kitchen appliances and television.

In reality, having the best RV generator is also a matter of safety. If you were stranded in a remote area without any electricity to charge your phone and call for help, you could be putting yourself in harm’s way.

How the Best RV Generator Works

The best RV generator works by converting the energy in gasoline into electricity. A small two or four-stroke gasoline engine moves the wire around a magnetic field.
In turn, the forces of the magnetic field and wire cause electrons to flow through internal wires, which typically consist of copper.

​Introducing the Best Generator Options

The best RV generators come in a wide variety of sizes and form factors.


Westinghouse WGen7500 Portable Generator

No products found.

The first of the best RV generator options is the Westinghouse WGen7500 Portable Generator. This model has 7,500 running watts and a peak wattage of 9,500.

One thing we like about this model is that it has a remote starter and key fob. That way, you can start it from within your RV if you don’t want to get out of bed or face uncomfortable weather conditions.

Furthermore, note that this model has a 6.6-gallon fuel tank, which lasts up to 16 hours of run time.

In addition, note that this model is a complete package that includes a 12-volt battery charger, oil, an oil funnel, and a tool kit.

Plus, the manufacturer backs this generator with a three-year warranty, which is longer than the average manufacturer warranty.

Overall, this model earned 4.4 out of 5.0 stars on Amazon. Unfortunately, a leading negative customer review claimed the battery on their model was dead and that it wouldn’t hold a charge.

On the other hand, a positive review remarked that Westinghouse provided excellent customer service and that their generator worked well.


  • ​9,500 peak wattage
  • ​16 hours of run time
  • ​Large 6.6-gallon tank


  • ​Very expensive


​Westinghouse iGen2200

No products found.

The next of the best RV generator models is another Westinghouse product. The Westinghouse iGen2200 is a compact model with a convenient carrying handle on top, though it lacks the wheels that most other frame-mounted generators have.

This model, however, isn’t as powerful as the previous Westinghouse model. Being that it’s smaller, this generator only has 1,800 rated watts and a peak wattage of 2,200.

Nevertheless, it’s highly portable and relatively light for a generator because it only weighs 46 pounds.

We liked that in addition to two 120-volt outlets it also has two USB outlets for charging smartphones, tablets, and other electronics.

The manufacturer claims that it’s a quiet alternative to bigger, noisier generators too because it is only 52 decibels loud.

It does have a smaller fuel tank though, which only holds 1.2 gallons of gas, giving it a total run time of 12 hours.

Altogether, this model earned 4.4 out of 5.0 stars from aggregate Amazon customer reviews.

One of the leading positive reviewers remarked that it’s extremely fuel-efficient, powerful, and quiet. Conversely, a leading negative review stated that after two months, their generator failed to start.


  • ​Compact and lightweight
  • ​Quiet
  • ​Large 6.6-gallon tank


  • ​Not as powerful as larger generators
  • ​Only 2,200 peak wattage


​Champion 3500-Watt RV Ready Portable Generator

No products found.

The next contender for the best RV generator is the Champion 3500-Watt RV Ready Portable Generator.

One perk of this model is that it has a sensor to detect low oil and automatically shut off. Also, note that it has a 0.6-quart oil capacity and that the manufacturer recommends 10W-30 oil.

This generator, however, is more towards the runty end of the bell curve, and only provides up to 3,500 running watts.

Nevertheless, we did like that it runs for up to 12 hours at a time. And it has a volt guard safety feature that prevents voltage spikes as well as a voltmeter that helps you quantify and measure voltage.

We also liked that, being that it’s a smaller generator, it doesn’t make as much noise as the larger models. At 23 feet away, this model is only 68 decibels loud.

Furthermore, note that this model comes with a three-year limited warranty, which is fairly long as far as warranties are concerned.

Altogether, this model earned 4.5 stars out of 5.0 stars from Amazon customer reviews.

A leading positive customer review said this is a great generator that helped power their refrigerator during a hurricane. On the other hand, a leading critical review said this model is only good for RV recreation, and not for full-time use.


  • ​Fairly inexpensive
  • ​Compact
  • ​Runs 12 hours at a time


  • ​Not the most powerful generator


​Champion 4000-Watt RV Ready DH Series Generator

No products found.

The next of the best RV generator options is another Champion model. This model has a lot in common with the previous generator and is relatively quiet.

The manufacturer claims this generator is only 64 decibels loud, and that it’s 50 percent quieter and 20 percent lighter than the traditional Champion generator.

And not only does this model have 3,500 watts of running power, but it also lasts for up to 17 hours on a single tank of fuel.

It’s perfect for RV owners due to its 120-volt 30A RV outlet, though it does also have two 20A household outlets as well.

It also has an optional parallel kit that allows you to connect it to an inverter or digital hybrid to expand its power.

And like other Champion generators, this model comes with a standard three-year warranty.

Overall, it did fairly well on Amazon too, where it earned 4.3 out of 5.0 stars from customer reviews. Unfortunately, a negative customer review claimed their model was defective and that it would only run for three hours at a time.

On a more positive note, a satisfied customer review claimed it is quiet, powerful, and fuel-efficient.


  • ​Runs for up to 17 hours
  • ​Quieter than other Champion models
  • ​Three-year warranty


  • ​Rather pricey


​A-iPower SUA2000iV

No products found.

The next best RV generator is extremely compact, and only about the size of a small suitcase. This model is more than 40 percent cheaper than the previous generator, though it only has 1,600 running watts.

The A-iPower SUA2000iV only runs up to seven hours at a time at half capacity, however. And it’s fuel tank is relatively small, and only holds 1.1 gallons of fuel.

Though it isn’t as powerful as the larger generators, it does have the advantage of being quieter than most other models. It only makes 58 decibels of noise at half capacity, and it’s parallel-ready.

However, do be aware that this model doesn’t come with a parallel kit.
It fared well on Amazon too, where it earned 4.2 stars out of 5.0 stars from aggregate customer reviews.

A positive reviewer even claimed that it performs above its price point and that after 600 hours of run time, there have been no issues at all.

Conversely, negative reviewers claimed their model was missing parts on arrival and that it spilled oil upon delivery.


  • ​Extremely small
  • ​Moderately priced
  • ​Extremely quiet


  • ​Only 1,600 watts of running power
  • ​Short run time


​Westinghouse iGen4200

No products found.

The Westinghouse iGen4200 is the next best RV generator alternative and uses gasoline to generate energy. Be aware that this model has a mid-to-high price range, though it does deliver more power than most of the preceding models.

As its name implies, this generator produces up to 4,200 watts of peak power, and it has an open frame inverter too.

What we really liked about this model is that it’s plug-and-play, and comes with everything you need. The manufacturer includes oil, an oil funnel, a tool kit, and a user’s manual so you can use the generator as fast as possible.

We also liked that it has a fairly large fuel tank. The tank holds up to 2.6 gallons of gasoline, and it can run for up to 18 hours with its efficiency mode, which saves fuel.

It’s relatively quiet, though not the quietest model by any stretch of the imagination. Nevertheless, 62 decibels is subjectively quiet for a generator.

This model earned 4.0 out of 5.0 stars on Amazon too, and a leading reviewer claimed it was a great value and that it runs well. On the other hand, a critical review claimed their generator failed to start.


  • ​4,200 watts of peak power
  • ​Plug-and-play
  • ​Up to 18 hours of continuous use


  • ​Not the cheapest model
  • ​Not the quietest generator


​DuroMax XP10000E

No products found.

The DuroMax XP10000E is another suitable alternative for the best RV generator. Compared to most of the previous units, this model is a behemoth and offers 8,000 watts at peak usage.

This model is larger than most of the previous alternatives, and the frame has wheels to accommodate its large size.

Like the previous model, this generator is also plug-and-play. Also, notable features include a voltage meter, circuit breakers, idle control, and a low oil indicator. And not surprisingly, this model is backed by a three-year warranty.

All in all, this generator earned 4.0 out of 5.0 stars on Amazon, and a positive review remarked they were impressed with this generator’s power output.

However, a negative review claimed their model stopped generating electricity after only an hour.


  • ​The frame has wheels
  • ​Low oil indicator
  • ​8,000 peak wattage


  • ​Large and heavy
  • ​Extremely expensive


​WEN 56380i

No products found.

The WEN 56380i is another suitable alternative for the best RV generator. This model meets all EPA and CARB compliance regulations, and its 212cc OHB engine creates up to 3,800 surge wattage and a run time of 8.5 hours at half capacity.

This model is also capable of charging tablets and smartphones with its USB port. Also, it has a digital load and fuel display to help keep track of usage metrics.

Plus, it has a unique fuel shutoff feature that uses up the remaining fuel in the carburetor to protect the generator’s lifespan.

We found it odd that this model only has a two-year warranty instead of a three-year warranty, though.

Amazon customer reviewers gave this model an aggregate rating of 4.4 out of 5.0 stars too. However, a leading critical review said their generator broke after only two months.

More positively, another customer review said it was reliable enough to use eight hours every day for at least four months.


  • ​Fuel shutoff feature to maximize efficiency
  • ​212cc engine
  • ​USB port


  • ​Extremely costly
  • ​Only 8.5 hours of run time at half capacity


​Duromax XP4850EH

No products found.

The final of the best RV generator models is the Duromax XP4850EH. Due to its size and weight, the manufacturer mounted wheels to its frame for easier portability.

And there were two things we liked about this model. First of all, it is moderately priced and nowhere near the high end of the pricing spectrum.

Second of all, it has dual-fuel technology. You can choose to either power it with gasoline or propane, making it more versatile than the average generator.

Furthermore, it has a running wattage of 3,850 to handle heavy demands. And it has a large four-gallon tank as well.

Overall, Amazon customers rated this model 4.0 out of 5.0 stars, though a negative customer review claimed their model had a faulty propane regulator.

But a positive reviewer claimed their model was flawless.


  • ​Four-gallon tank
  • ​Moderate pricing
  • ​Uses propane and gasoline


  • ​Not the most powerful generator
  • ​Large and heavy
