If you’re searching for the perfect power source for your motorhome, you are in great luck. We have put together a list of the 5 best RV generators available on the market based on our hands-on user experience so you get a clear picture of how good they really are.

Top 5 Best RV Generators Reviewed

01 Westinghouse WGen9500DF 12500 Watts Dual Fuel (Editor’s Choice)

Westinghouse WGen9500DF 12500 Watts Dual Fuel

Why It Stands Out to Us

The WGen9500DF from Westinghouse has high-performance written all over it. Coming with a muscular build, this beast of a generator generates a massive amount of power that’s overkill for most RVs. You can use all of your appliances and there will be plenty of juice left in the engine. It runs efficiently on both gasoline and propane.

With this unit, you’ll never run out of power outlets. Despite being an all-rounder, it doesn’t fall too heavy on your wallet. It’s undoubtedly one of the best portable generators on the market. No wonder it clinched the top spot on our list. If you want an abundance of premium features and a smooth service in your generator, this is a no-brainer. 

Our Experience With the WGen9500DF

  • The bulky construction was a treat to the eye and the material used also seemed pretty strong. Overall, it gives an all-performance vibe by the looks.
  • It had an easy set up and we didn’t need more than 10 minutes to start the engine. In terms of starting methods, we were very satisfied. The unit featured an electric start, recoil start, and remote start. All of the methods worked accurately throughout the time.
  • You can power an entire facility with this model. We powered all the appliances available in the RV and still couldn’t overload it. We connected a 64” LED TV, a 15000 BTU AC, a sound system, 3 fans, some light bulbs, a coffee machine, a refrigerator, and a few other smaller gadgets.
  • On a half load, the unit produced 12 hours on a full tank. When we tested it with a full load, it triggered the low fuel shutoff after 8 hours of operation. Considering the number of devices we powered with it, that’s an amazing runtime.
  • The WGen9500DF features every power outlet you can expect from a top-quality portable generator. The outlets were nicely labeled and were very easy to use.
  • You’d expect a generator of this kind of capacity to make a loud noise but the operational noise wasn’t too loud. However, it made an audible sound that can be a red flag for some users.
  • In terms of portability, the wheels worked like magic. We loved the fact that the wheels came with the package. The handle stood up as well.
  • The low oil shut down was accurate every time we triggered it.  The engine turned off as soon as fuel reached a certain point.
  • We tested the generator with both gas and propane. Though it showed a tendency to run better on propane, we were happy with the dual fuel feature.

What We Didn’t Like

  • The metal construction combined with the huge fuel tank makes it almost too heavy for one person to transport it.
  • It made an audible noise.

What Could Be Improved

  • The noise could be suppressed a bit.

Our Recommendations

  • If you run the unit on propane all the time, make sure to start it on gas at least once every month.

02 Champion 100307 4375/3500-Watt Dual Fuel

Champion 100307 4375/3500-Watt Dual Fuel

Why It Stands Out to Us

The Champion Power Equipment 100307 is packed with a wide variety of features and functionalities that will blow your mind.  For starters, you can’t but admire the black and yellow construction of the unit. The powerful engine is capable of powering a whole bunch of electric appliances in your RV.

With plenty of 30 and 20 amp options, you’ll never run out of power supply. Despite the premium service, the 100307 costs you less than most other models with similar attributes. Considering the well-rounded service, the Champion 100307 is your go-to choice.

Our Experience With the Champion 100307

  • Featuring the trademark black and yellow design of Champion Power Equipment, this unit was a treat to the eyes. The construction was solid and the materials seemed pretty tidy as well.
  • The setup was very straightforward. The generator was ready to start within 10-15 minutes. Besides, the manual seemed very well-thought as well.
  • The recoil start worked accurately and we could start the engine on the first attempt almost every time. Pulling the cord was so easy that even a child could switch it on without trying too much.
  • We were satisfied with the power outlets. The number of outlets was sufficient for a regular-sized RV. It featured two 120V 30 amp outlets (1 regular RV outlet + 1 locking outlet) and two 120V 20 amp outlets, which will be overkill for most users.
  • For testing the fuel efficiency and runtime, we used a whole bunch of electric appliances. We powered a 64” LED TV, a ps4, a sound system, a mini-refrigerator, two fans, two lights, a guitar amp, two mobile chargers, and a laptop charger with the unit without an issue.
  • On a 50-60% load, it gave 11 hours of runtime before emptying the tank completely. On a full load, we could get about 7 hours of service with a tank full of gas.
  • The dual-fuel feature was spot on. While most generators with dual fuel tend to perform better on propane, the Champion 100307 gave us almost equal results on both fuel types.
  • Champion included a wheel kit with the unit and it worked like magic. Though the 100307 weighs a little more than 100lbs, it was very easy to move it from one place to another because of the wheel kit and the handle.
  • We tested the low oil shutoff feature a few times and it worked accurately on each occasion. The engine turned off immediately after the fuel went below a certain level.

What We Didn’t Like

  • This model doesn’t feature an electric start.
  • It made a loud noise.

What Could Be Improved

  • If the handle was a bit bigger, it would have improved the portability by a large margin.

03 DuroStar DS13000EH Dual Fuel 13000 Watt

DuroStar DS13000EH Dual Fuel 13000 Watt

Why It Stands Out to Us

The DuroStar DS13000EH features a 500cc engine that runs on both gasoline and propane. With a whooping 10500W of running power, this workhorse will power an entire facility and still have plenty of juice left. It also comes with a multitude of power outlets including a 240V 50amp outlet, which you won’t see often in portable generators. If you want an abundance of power and a wide range of useful features in your RV generator, give it a try.

Our Experience With the DuroStar DS13000EH

  • From the looks, we can guess that the manufacturers worked hard to keep the unit as compact as possible. The muscular build seemed sturdy enough to last for years. The design was pretty neat as well.
  • It featured both electric and pull start and both options worked fine. Except for a few occasions, we were able to start the engine on the first attempt.
  • You can’t complain about the power outlets of this model. From 120V 30amp outlets to 240V 50amp ones- it featured every outlet that we can expect from a high-quality generator.
  • To be honest, the power it packs is going to be overkill for most motorhomes. We powered all the electrical devices that were available in the RV and still couldn’t put a full load on the unit. It powered a 15000 BTU air conditioner, a 64” LED TV, a refrigerator, 3 fans, 3 lights, a coffee machine, a microwave, and some other smaller devices with ease. The flow of energy also seemed to be pretty stable.
  • We were impressed by the runtime. On a 50% load, we got a little over 14 hours of service on a full tank. On a full load, the average runtime was 8 hours, which is impressive considering the massive amount of load it took.
  • Performance was almost identical in both gas and propane. Besides, the low fuel shutoff worked perfectly every time.
  • Though it wasn’t the quietest model we used, the operational noise wasn’t anything excessive. It’s very unlikely that you’ll find a quieter unit that generates this much power.
  • The multimeter seemed very useful for keeping track of the voltage being used.

What We Didn’t Like

  • DuroStar didn’t include a wheel kit with the unit.
  • The operational noise might be problematic for some users.

What Could Be Improved

  • The noise could be suppressed a little.
  • An hour meter could be included.

Our Recommendations

  • If propane is your go-to fuel, make sure to start the unit on gas at least once a month. This will increase the longevity of the engine.

04 Champion 4000-Watt DH Series

Champion 4000-Watt DH Series

Why It Stands Out To Us

The 4000W inverter from Champion Power Equipment is one of the brand’s highest-selling generators.  Featuring the trademark black and yellow construction of Champion, this is an eye-catching generator. With a whooping 4000 watts of power, it’s capable of generating enough juice for a whole bunch of appliances in your motorhome. Besides, being an inverter generator, this model comes with the assurance of a clean flow of energy. It’s a performance beast that surprisingly doesn’t cost much compared to other similar models on the market.

Our Experience With the Champion 4000-Watt

  • Like all Champion generators, the design and build material on this one was top-notch. The iconic black and yellow construction seemed sturdy enough to last for years.
  • Though it didn’t feature an electric or remote start, we were satisfied with the performance of the recoil start.  Pulling the cord was fairly effortless and it started on the first attempt pretty much every time.
  • Connecting it with an RV was a piece of cake. The setup took just 10 minutes and the unit was ready to run almost immediately.
  • We powered almost every piece of electronics that was available in the RV with the unit and it seemed to handle them very well. We used an LED TV, a small refrigerator, two fans, three lights, a sound system, a mini projector, two cell phone chargers, and some small gadgets.
  • With a full load, we got upto 12 hours of service before we had to refuel. A half load on the other hand emptied the tank after 17 hours of running at a stretch.
  • Regarding the power outlets, there wasn’t much to complain about. One 30A RV outlet and two 20A household outlets seemed enough for a 4000W generator. The USB adaptors worked perfectly as well. Most importantly, all of these outlets provided a stable flow of clean energy.
  • We tested the low fuel shutoff quite a few times and on every occasion, the generator turned itself off almost immediately the fuel went below a certain level.
  • For how affordable it is, the operational noise was exceptionally lower than our expectations. However, it’s not a silent generator by any means. It made an audible hum while running, which wasn’t too annoying.
  • Though the unit didn’t come with wheels, we coupled a Champion wheel kit and the portability was instantly improved. Moving it from one place to another was all fun and games. The handle worked perfectly as well.

What We Didn’t Like

  • It didn’t come with a wheel kit and we had to buy it separately.
  • It didn’t feature an hour meter.

What Could Be Improved

  • Adding an hour meter would have benefitted the users a lot
  • Electric start feature could be included
  • The noise could be suppressed a bit

Our Recommendations

  • If you’re a heavy user, make sure to clean the tank every once in a while

05 Jackery Portable Power Station Explorer 500, 518Wh

Jackery Portable Power Station Explorer 500, 518Wh

Why It Stands Out to Us

The Explorer 500 from Jackery is one of the most lightweight and compact power stations you’ll ever find. It features an eye-catching design and premium build quality. This model doesn’t run on fossil fuels. The battery can be charged with either an AC adaptor or a solar panel that makes it cost-efficient.

It can take care of the smaller and less demanding devices in your RV while making no noise at all. If you’re looking for a backup power station for your motorhome, go for the Explorer 500 and you won’t regret it.

Our Experience with the Jackery Power Station Explorer 500, 518Wh

  • This was one of the most compact generators we ever used. The design and build quality were satisfactory. The build material felt premium to the touch.
  • The control was very easy and straightforward. Everything was self-explanatory. We gave the manual a read and found out that the manufacturers added every bit of information a user might need to use this model in the book.
  • With the AC wall charger, the power station charged in just 7-8 hours. Though it didn’t come with a solar panel, we tested the charging with a 100-watt solar panel. It took about 12 hours to fully charge the generator with solar energy.
  • Since this wasn’t a powerhouse by any means, we used it as a backup power station most of the time. We used it the most while out camping. It was more than capable of running small electric devices like a mini-fridge, fans, light bulbs, mobile chargers, laptop chargers, and so on.
  • The Explorer 500 produced very little noise when working. We could barely tell that the unit was running while it was operating at maximum capacity.
  • We loved the little LCD panel on the unit. It showed every bit of important data that we needed. It seemed like a very useful feature.
  • The unit weighed just 13 pounds and was very easy to lift with just one hand. The handle seemed very strong throughout the time. Regarding portability, there is no match for the Explorer 500.

What We Didn’t Like

  • We were limited to use small devices only due to the small wattage
  • It takes a long time to charge
  • A solar panel wasn’t included in the package

What Could Be Improved

  • A solar panel could be added.
  • The manufacturers could have covered the outlets.
  • The flashlight could be brighter.

Best Portable Generator for RV and Camping: Buying Guide

best rv generator for home

1. Power Level

best generators for rv use

Recreational vehicles require a substantial amount of power. However, you can’t tell that a generator with certain wattage will be enough for your RV. For determining the power level, you need to figure out how much power your appliances require.

Besides, you need to keep in mind that electrical devices have two kinds of watt requirements- starting and running. Normally, starting wattage of a device is almost double the running wattage.

For example; a 15000 BTU AC has a running wattage of 1500W but it requires about 3500W to start. So, to run a 15000 BTU AC, your generator needs to have a wattage of 3500. So, calculate the wattage required by all the appliances you’re planning to use in your RV, and then go for a certain unit.

2. Noise Level

Unfortunately, most generators you’ll find on the market aren’t as silent as you’d like them to be.  Most generators produce an average of 48-65 dBA of noise from 50 feet of distance. This can translate into 78-95 dBA of noise within your motorhome.

For better understanding, 60 dBA is the average noise level of a normal conversation and anything over 80 dBa could harm your health. Usually, inverter generators make less noise compared to conventional generators.

3. Portability

You might think that your generator will be lying in a corner of your RV for the rest of your days but you never know when you’re going to need it outside. That’s why portability is important. Two elements play a vital role here: weight & size.

Now, these two elements depend on the wattage and the features your generator facilitates. Keep in mind that more wattage means more weight in the unit. So, avoid stacking up on the wattage and try to keep it as compact as possible.

4. Fuel Availability & Efficiency

As you’re probably going to be on the move most of the time, the safest option will be to go for a generator that runs on the kind of fuel you are already using in your RV. If your motorhome is a class A diesel pusher, diesel would be the safest option for you. However, you can still go for units that run on another type of fuel.

Here are the fuel types with a bit of insight into their efficiency in running generators-

a) Diesel– Diesel usually burns way cleaner than gasoline and is more efficient. However, diesel can be hard to find, and typically diesel generators are louder and heavier than the other types.

b) Gas– Most generators run on gas. So, gasoline is very easy to find. Keep in mind that gasoline doesn’t burn as clean as diesel.

c) Propane– Propane burns the cleanest among the three. They’re also the cheapest option. However, propane isn’t as easy to find as gas.

Some generators come with a dual fuel feature, which means they can run on both gas and propane. Though most dual fuel generators tend to perform better on propane, there are still units that run equally on both. Before going for a generator that runs on a certain fuel type, make sure it’s available to you whenever you need to refuel.

5. Types of Generator

i) Conventional Generator

Conventional generators run on diesel, propane, or gasoline and use an alternator to turn the mechanical energy of the engine into electrical energy by using an alternator. Usually, they’re designed to operate at 120v at 60hz of frequency. In terms of wattage, they can produce 300-10000 watts of power. However, they’re louder and less portable than the other streams of generators.

ii) Inverter Generator

Inverters have a different fanbase due to the advanced technology used in them. These generators convert high-frequency AC electricity into DC electricity and then turn that DC energy into stable AC electricity. This allows them to generate cleaner energy than their conventional counterparts. Inverter generators usually are smaller and make less operational noise. They’re often more portable than the conventional units as well.

iii. Solar Generator

These are the most advanced stream of generators. Solar generators can charge their battery with solar panels, which will most likely take place on the roof of your motorhome. The solar panels convert solar energy (sunlight) into electrical energy. They’re more eco-friendly, more portable, and quieter than the other types of generators.

There are some limitations to the solar generators though. You can’t get sunlight at night and on rainy days. So, the best option is to keep solar generators as a backup plan rather than using them as your daily driver.

6. Altitude Kits

As altitude increases, the air pressure starts decreasing and the air becomes less dense. With less air to breathe, the engine of a generator doesn’t perform as efficiently in areas with a higher elevation. Most generators come with a recommendation of a certain altitude for best performance, which typically ranges from 4000 to 5000 feet.

If your travel route includes areas with a high altitude, we recommend getting an altitude kit. Altitude kits work as a performance booster in higher altitudes. These brand-specific devices control the flow of fuel and make your generator operate quieter and smoother.

7. Affordability

The price of an RV-ready generator depends on different elements like size, fuel efficiency, wattage, noise level, parallelling capabilities, and so on. You can get a unit for $500 while some branded models will cost as much as $10000 depending on the features they facilitate. You can save a few bucks by opting for a conventional unit or go for an inverter with all the best features. It all comes down to the kind of money you’re willing to spend. So, determine your budget before you start looking for RV-ready generators on the market.


Q. 1: Can you run an RV generator overnight?

Ans: RV generators are built to have an extended period of runtime. So, if you power sufficient appliances with your RV generator, you can run it overnight.

Q. 2: Do you really require a portable RV generator?

Ans: RVs facilitate a wide range of electrical appliances and devices that require a substantial amount of electric energy. So, it’s evident that you’ll require a reliable source of power. Without a portable generator, you’ll just be camping in your motorhome.

Q. 3: How to protect a portable generator from rain?

Ans: First of all, never keep the generator outdoors without a shelter. If you do, make sure it’s protected by a waterproof cover. Lastly, unplug and turn off your generator when it starts raining during operation outdoors.

Q. 4: What is the lifespan of an RV generator?

Ans: An RV generator lasts for about 2000-3000 hours depending on its overall quality. If regularly maintained, your generator can keep providing service for 5-10 years. However, it depends massively on how many hours you run it each year.

Q. 5: How to maintain my new RV generator?

Ans: First of all, if there’s an hour meter, keep track of it. Change the fuel frequently and never reuse the oil. Get your generator professionally serviced at least once a year. Always put a protective cover on it when it’s not running. And last but not least, keep it clean.
