Brief Intro to Synopsis

We too hate reading through long posts, This article is going to be straightforward. It will answer four specific questions. (Click to go straight to the answer)

1. Is Money Most Important To You?

2. Value Portability over Everything Else?

3. Want to Protect Your Ears?

4. Want Nothing but The Best?


1. Westinghouse WGen7500 – Best RV Generator Overall

Best Generator for RV - Westinghouse WGEN7500

In addition to being great for camping, the gasoline-powered WGen7500 is also a brilliant choice for tailgating, emergency backup and more.


Starting with a glance at some technical features, the WGen7500 boasts a couple of Ground Fault Circuit Interceptor (GFCI) receptacles – and an additional L14-30R receptacle. In plain English, what these parts do is to make the generator provide power for virtually all of your applications.

Fuel Consumption

On the fuel-consumption side, the WGen7500 has done away with the age-old side-valve engine. In its place has come the overhead valve engine which – by complementing the 6.6-gallon fuel tank – massively improves the fuel efficiency of this model by providing a run time of 16 hours on a full tank.

Also, while it does have Start and Stop buttons to turn the generator on/off, our favorite is the remote key start. The remote lets you switch on and turn off the generator from a close distance. All you have to do to use it is to turn the key in the remote.

Safety of the model is guaranteed as it is certified by CAR board, Canadian Standards Association, and EPA.

It has an automatic shutoff feature which, on detecting low oil level, safely shuts down the model. Also available are twist-lock rubber covers which protect all outlets. Then comes the cast iron sleeve which – on combining with the top roll bars – protects it from drops.

Key Features

  • 9000W starting and 7500W continuous power
  • Cast Iron Sleeve and top roll bars
  • The huge gas tank of 6.6 gallons
  • Sound mufflers damp down operating sound to a safe 64 dB level
  • Has a digital hour meter, fuel gauge, and easy-to-use control panel
  • Automatic low-oil shutdown and spark arrestor
  • Up to 16 hours of runtime
  • Lots of reliable safety features
  • Includes a 12-volt battery charger
  • Comes with a 3-year warranty
  • Heavy

User Critique

As common sense tells us, any generator which weighs 200 pounds isn’t, by any stretch of the imagination, portable.

2. DuroStar DS4000S – Best Budget RV Generator

Best Generator for RV - DuroStar DS4000S

In case you liked the features of the Westinghouse WGen7500 – but was deterred by its price tag – the DuroStar DS4000S has got you covered.


First things first, since this model has a heavy-duty steel frame, it provides two specific benefits. First, with no rattle, there is less chance of any wear and tear. Second, with no vibration, it shows its care for your ears by operating at 69dB.

Safety Feature

Turning our attention to its startup, this model’s EZ-pull recoil starter makes it a cinch to get going. You also get a low oil warning light on the control panel. However, if you don’t notice it, the generator will safely shut down thanks to its automatic shut-off feature.

Furthermore, if you’re operating at 50% load, it allows a maximum runtime of 8 hours provided you’ve filled its 4-gallon tank to capacity. It also has a gas gauge to keep you abreast of the gas level throughout the operation.

Also, with its rated running wattage of 3300 watts, it can power a coffee maker, a microwave and a refrigerator all at once. It gives 2 plugging areas: a 120V, 20-amp outlet, and a 120V, 30-amp twist lock outlet.

Key Features

  • 4000W starting and 3300W continuous power
  • 8 hours runtime at 50% load
  • 4-gallon gasoline tank
  • Sound mufflers and a 69dB noise levels
  • A large number of outlets
  • Heavy-duty steel frame
  • 8 hours runtime at 50% load
  • Low oil shutdown and air-cooled
  • No wheels

User Critique

Although it doesn’t weigh as much as the Westinghouse, the DS4000S has its own shortcoming: it doesn’t have wheels. Provided you want them in the package, you’d have to pay extra.


3. Westinghouse iGen4500

Best RV Generator - Quiet Westinghouse iGen4500

With its included key fob, a telescoping handle and electric and recoil start options, the iGen4500 offers you a good alternative in case the abovementioned models failed to satiate your appetite.


To start this generator, the iGen4500 provides three options: a remote key-fob, a push button electric start, and recoil. It has two 120V, 20A outlets and a single 120V, 30A outlet. You also get two 5V USB ports on the control panel.

In case you haven’t used invertor generators before, the iGen4500 will certainly impress you. Thanks to its conversion technology, it provides a constant flow of current – without any fluctuations. The result is a quieter operation with a 52dB noise level – less than that of human conversation.

Thanks to its sophisticated engine, this generator has an above-average runtime of 18 hours – despite the fact that its tank capacity is a mere 3.4 gallon. What’s more, it gives you the choice to improve its efficiency by including an “Efficiency Mode” in the package.

Another notable feature of this model is its LED data center. With its rotating digital display, the data center displays useful features including the power output, fuel level, voltage output, remaining runtime and lifetime hours.

Key Features

4. Champion 3100-Watt – Best Portable RV Generator

Best RV Generator - Champion Portable 3100W

What is it that makes a generator ultra-portable? Three features: wheels, lightweight, and ease of maneuverability. It is only fitting, then, that the Champion boasts all three of them.


In case you are wondering, there are three specific features which make this model ultra-portable. First, it has a mobility kit – which includes NEVER FLAT tires and foldaway “U” shaped handle. Then comes the built-in carry handle which aisfurther aided by the under-100lb weight of this model.

Making sure that you remain safe while using this model is its push-to-reset circuit breakers. Granted, they aren’t as good as their automatic counterparts. Still, they are good than those age-old fuses which we see in conventional generators.

Moving on, with its running engine power of 2800 watts, the 1.6-gallon tank of this inverter provides a runtime of 8 hours at 25% load. Further ameliorating the fuel consumption is the economy mode – which switches the unit to idle mode to save fuel.

What’s more, thanks to its included key fob, this model lets you start (and stop) it from a distance of up to 80 feet away. Equally convenient is the Quick Touch Panel which, by collecting all the controls in one spot, makes operating this model a cinch.

Key Features

  • 3100W starting and 2800W continuous power
  • 8 hours runtime at 25% load
  • 6-gallon gasoline tank
  • 58dB noise level
  • Two USB outlets, two 120V, 20A outlets, and one TT-30 30 Amp outlet
  • Wireless remote control start and shutdown
  • Stable output for sensitive electronics
  • Comes with a 3-years warranty
  • Not THAT much power output

User Critique

People who sign up for portable generators know that portability is a double-edged sword. While it no doubts make maneuvering the model easily, it reduces the power output.


5. Champion 3800-Watt Dual Fuel

Best Generator for RV - Champion 3800W Portable

Though this model doesn’t offer quite the same bit of power as other Champion models, it offers all the great features and quality, and that too in an affordable price tag.


Powered by a 224cc engine – which is famous for its dependability, this generator has a 3.4-gallon gas and 20 lb. propane tank. Its runtime varies too, as a full tank of gas gives you up to 9 hours of electricity, whereas, on propane, you get a slightly better 10.5 hours runtime.

Furthermore, this model has a cold start technology which means you won’t have to wait to put a load on it. Also provided is a touch start, push-electric button – and you even get a batter included in the package.

In terms of safety, you won’t find any fault with this model. It has a volt guard surge protector which protects your sensitive electronics from any spikes or surges. It also has an auto shut-off function which turns the generator off when the fuel gets low.

A gauge on its front panel does wonders to increase the ease-of-use of this model. It not only keeps you informed of power output – but also gives indicators as to when/if the model needs maintenance.

Furthermore, it has four 60 Hz. outlets to let you charge your devices straight from the generator. All of these outlets are protected by the volt guard – and the whole unit comes with a 3-year limited warranty.

Key Features

  • Volt Guard protector
  • Touch Start, push-button electric start
  • Volt guard and Auto-shutoff
  • Considerable run times on both fuel types
  • 3 years limited warranty
  • No USB outlet

User Critique

In contrast to most other generators in this review, the Champion 3800W Dual-fuel doesn’t come with a USB outlet.


6. DuroMax Hybrid Dual Fuel XP12000EH

Best RV Generator - DuroMax Hybrid

Just like the abovementioned Champion 3800W, the DuroMax Hybrid has dual fuel compatibility. Unlike it, however, it offers runtime (in both fuels) in double figures.


As a mere glance over its starting power of 12000W will tell, this machine is not to be taken lightly. It makes good use of all this power, though, as it provides a runtime of 10 hours and 20 hours on gasoline and propane, respectively.

Having so much power, however, doesn’t mean that this machine will cause your ears to go deaf. Instead, thanks to its Four-Point fully isolated motor mount and quiet muffler, the DuroMax operates at less than 74 dB noise level – which is, at least, 11 dB less than the unsafe noise limit.

Yet another useful feature of this model is its Power Boost technology. Provided you want to power heavy-duty applications, this technology would let you double the power of the generator.

Turning our attention to its safety features, and the low oil shut-off comes into play. You also get the surge protector to shield your more sensitive electronics from power spikes.

Equally useful on the safety count – though as impressive on the convenience count as well – as the control panel of this model. It includes, among other indicators, an oil warning light, circuit breaker, and voltmeter.

Move your head to a little left of the panel, and you’d come across the “Easy Start Guide”. That means you can get the DuroMax up and running with ease – and that too without going through its verbose user manual.

Key Features

  • 12000W starting and 9500W continuous power (on gasoline)
  • 10200W starting and 8075W continuous power (on propane)
  • 10 hours gasoline runtime at 50% load
  • 20 hours propane runtime at 50% load
  • 9-gallon gasoline tank and 10-gallon propane tank
  • 74dB noise level
  • Auto shut-off and spark arrestor
  • Considerable runtime
  • Low oil shut-off and spark arrestor
  • Heavy duty frame
  • Heavy

User Critique

In case you didn’t know what you’re getting with the DuroMax, it is an absolute monster in terms of power. That, in turn, means that this machine can be anything but lightweight.


7. Briggs & Stratton 30675

Best RV Generator - Briggs Stratton Inverter

As the design of the Briggs and Stratton indicates – since it looks more like a vacuum cleaner than a 6500W generator – this model is incredibly convenient to use.


Starting with a glance at its design, and our judgment about its compact size were true. According to the manufacturer, the model is 45% more compact & 30% lighter than a similarly powered, standard portable generator.

Obviously, its looks aren’t the reason we’re recommending you this model. It has a QuietPower Series inverter technology which only gives stable power supply but also does so discreetly alongside its noise-reducing shell. For, this model churns out 66dBA noise at 25% load.

In terms of power supply, the Q6500 provides 5000W power supply continuously with a runtime of around 14 hours at 25% load.

While its recoil start type is obviously a downer – since most generators nowadays opt for push-button starts – Briggs and Stratton make up for this shortcoming by providing all seven – yes, SEVEN – of its outlets with a twist lock for safety.

Of those seven attachments, two are USB outlets to let you charge your smartphone and similar devices. The remaining five are all 120V – 20A outlets to give you more connection options.

Key Features

  • 6500W starting and 5000W continuous power
  • 15 hours runtime at 25% load
  • 5-gallon fuel tank
  • (4) 120V-20A outlets, (2) USB outlets & (1) 120V-240V locking outlet
  • Highly efficient, air-cooled engine
  • Lightweight and compact
  • Suitcase-style telescopic handle
  • 14hours runtime at 25% load
  • Not CARB compliant

User Critique

Since it isn’t CARB complaint, you cannot use this model in the state of California.

8. DuroMax XP4400E

Best Generator for RV - DuroMax XP4400E

At the cost of sounding hyperbolical, the DuroMax XP440E provides the best value for money. Would it suit you? Let’s find out.


With a starting power of 4400 watts – which later comes down to 3500 watts on starting – this generator has a below-average 4-gallon tank with an average 8 hours runtime at 50% load. The air-cooling in the 7 horsepower engine prevents it from overheating.

Even when the generator is running at full throttle mode, its super-quiet muffler keeps the noise down. That, when combined with the heavy-duty, vibration-resistant frame, tones down the noise level of this generator to 69 dB.

Moving around the generator is super-easy, thanks to its flip-up handle and wheels. Equally easy is the usage of this model, as its side is armed with a cache of controls – though it lacks a low oil level indicator.

Making up for its absence is the automatic low oil shutoff feature. You also get both manual and electric start options – and the generator provides both 120V and 240V outlets. What’s more, a battery is included in its package as well.

Key Features

  • 4400W starting and 3500W continuous power
  • 8 hours runtime at 50% load
  • 4-gallon fuel tank
  • (2) 120V-20A outlets, (1) 120V-240V outlet, (1) 12V DC outlet
  • EPA and CSA approved
  • Considerable runtime
  • Manual and electric startup options
  • Quiet and contains several useful controls
  • Small warranty period

User Critique

Compare its one year warranty with other models in this article, and you’d see that it is too low.

Best RV Generator - Champion 4000W

Since it pumps out a mammoth 3500 running watts, you can rely on this generator to power large appliances such as ACs, refrigerators and washing machines.


Starting with its standout feature, the Champion 4000 offers gasoline fuel capability. It has a 2.9-gallon fuel tank and provides 17 hours of run time at 25% load. You can increase the runtime even further by activating the “Economy Mode”.

To let you know that it is in working condition, its three LED lights are very useful. The first of these lights, when/if it blinks, means the generator is in “OK” status. The other two, meanwhile, give “overload” and “low oil” warnings, respectively.

In terms of outlets, a large number of useful options are on offer. You get a 12V cigarette lighter outlet, two 120V, DC outlets, and 1 120VC RV outlet. In case you end up overloading the generator, it has three reset buttons to get things back on track.

Impressively, while it doesn’t provide a parallel connection kit in the package, this model is parallel capable. That means you can connect it with another to increase the overall power supply. Also, it operates at an ultra-quiet level of 64dBA.

Key Features

  • 4000W starting and 2800W continuous power
  • 17 hours runtime at 25% load
  • 9-gallon fuel tank
  • (2) 120V-20A outlets, (1) 120V-240V outlet, (1) 12V DC outlet

10. Honda EU2200i 2200-Watt – Most Quiet RV Generator

Best Generator for RV - Honda EU2200i Inverter Generator

Think generators cannot be quiet? Then you haven’t come across the Honda EU2200i generator in your life. With its ridiculously low noise level, it is one of the quietest generators on the market.


Want to have good relations with your neighbors? Then get the Honda in your home. With its rated noise level ranging between 48 to 57dBA – which is less than normal human conversation – this model is ideal for users who prefer quiet operation.

Also, while it doesn’t offer universal parallel compatibility, you can add one Honda with the other for additional power.

Furthermore, since this is an inverter, this model provides not only stable power but also does so with fewer emissions. It has a fuel tank capacity of 0.95 gallons – and provided you activate its Eco-Throttle mode – you can get up to 9.6 hours of runtime on a full tank.

Lastly, it has an oil indicator letting you know in advance to refill the tank. Whether you’re going to use it for commercial or residential purposes, a 3-years warranty is on offer, too.

Key Features

  • 2200W starting and 1800W continuous power
  • 1 hours runtime at 25% load
  • 9-gallon fuel tank
  • (2) 120V-15A outlets, (1) 1) 12V DC outlet

11. Generac 5735 GP17500E

Best Generator for RV - Generac 5735 Portable

Available in both residential and commercial models – of which we’ll be reviewing the former – the Generac 5735 is a “Power” generator which provides extensive power.


Being the most powerful Generac generator on the market, the GP17500E starts at a power of 26250 Watts, before setting down at 17500 watts. In case you are wondering, this much power means that you can run an average-sized home with this machine.

Furthermore, its 16-gallon tank capacity acts as a double-edged sword for the Generac. Where on one end it gives it 10 hours runtime at 50% load, it makes it incredibly heavy, on the other. The tank takes only unleaded gasoline.

Unsurprisingly, given the massive output of this model, it relies on electric starting. Fortunately, both the battery as well as a plug-in battery charger jack is included in the package.

As for its controls, this generator’s control panel includes an idle control button. Turn it upwards, and you’d get an improved fuel efficiency when not drawing load from the model. The panel also has four 120V outlets, 1 120V, 3A outlet, and 12V DC output, among others.

Safety wise, you get an automatic shut-off feature with this model. The 1 ¼’’ steel tube cradle, meanwhile, has an integrated lifting eye which makes it easy to transport.

Key Features

  • 26,250W starting and 17,500W continuous power
  • 10 hours runtime at 50% load
  • 16 gallons fuel tank
  • (4) 120V outlets, (1) 120V, 30A outlet, (1) 120/240V outlet (1) 12V DC outlet
  • Electric Start
  • Loads of power
  • Impressive run time
  • Electric start
  • Not CARB compliant

User Critique

Since this model isn’t CARB compliant, you might not use it if you live in the state of California.

12. All Power America APGG10000

Best Generator for RV - America 10000W

The generators of All Power America in general – and APGG series in particular – range from 1,200 to 10,000 watts. The APGG10000, as suggested by its name, belong to the high-power spectrum.


First things first, while the APGG10000 has a starting power of 10,000watts, its running power rating is of 5,000 watts – with a surge rating of 6,000 watts. That means you can rely on it to keep your electric RV heater, refrigerator, microwave and water pump running.

The 8-gallon gas tank of this model, when added to its 291-cc engine, gives a running time of 11 hours provided you’re using 1/2nd of its 5,000-watt load. It also gives the option to electric start. And when the battery has gone dead, you can switch over to the recoil start.

Undoubtedly the best safety feature of this model is its low-oil shutdown. When the oil falls below the safe level mark, the engine will automatically shut off. That means there is no need to check the oil levels. Equally convenient is the no-maintenance battery and wheel kit supplied alongside.

In terms of sound, unfortunately, this model is one of the loudest. Even with a muffler, the best sound it could give is at 76 dB – which is the same sound you get when standing 50 feet from a highway. Granted, it isn’t THAT loud, but it still makes communication difficult.

Key Features

  • 10,000W starting and 5000W continuous power
  • 11 hours runtime at 50% load
  • 8 gallons fuel tank
  • (2-Ac Duplex 120V outlets, 1-120v twist-lock outlet, 1-120/240V twist-lock outlet, 1-12v DC
  • Electric and recoil start
  • 11-hour running time
  • No-maintenance battery
  • Enough power for the whole house
  • Loud

User Critique

As stated above, loud noise is one of the biggest shortcomings of this model.

13. Green-Power America GPG10000EW

Best RV Generator - Green Power Quiet

Another 10,000W generator, the Green-Power is equally loud, provides slightly more running power and has a slightly less running time than the APG10000 reviewed above.

Without further ado, let’s look at its features.


Justifying the presence of 420cc engine is the 7,500watt power output of this model. That means you can run two refrigerators, a microwave, and one fuel pump and charge numerous small devices. Also, you get a 9-hour runtime at ½ load from its 6.6 gallons tank.

Also, in contrast to what most people believe, high power hasn’t made this model a monolith. Instead, you can easily transport it around the camping site thanks to its collapsible transport handles and non-flat wheels.

Turning our attention to its efficiency, this GPG10000EW performs best when used at less than 50% load. The higher you go, the more fuel it will consume and the less will be the runtime.

More importantly, since it is equipped with an auto shutoff sensor, the generator turns off on detecting low oil level. It has a high-density Li-ion battery (included in the package) which has a runtime of over 10,000 charging cycles.

Key Features

  • 10,000W starting and 7500W continuous power
  • 9 hours runtime at 50% load
  • 6 gallons fuel tank
  • (4) 120-volt AC outlets, (1) 120-volt twist lock AC outlet, (1) 120/240-v twist lock AC outlet, and (1) 12-Volt/ 8.3A DC outlet
  • Electric and recoil start
  • Easy to move around
  • All outlets are covered
  • Non-flat wheels
  • Complaints about customer service

User Critique

Some users have argued that the customer service of the manufacturer isn’t responsive enough.

14. Cat RP7500E

Best Generator for RV - CAT RP7500E

Fed up with looking at generators which aren’t CARB compliant? Then you have an extra reason to consider the Cat RP7500E generator.


As loyal CAT customers might tell, the RP7500E is a departure from the traditional bulky generators belonging to the same manufacturer. With the result that you get a 192.5 pounds unit with solid rubber wheels and a padded double hinged handle making it maneuverable.

To make sure you can get it up and running in no time, CAT has provided this model with all the assembly tools, a bottle of engine oil and even a funnel. All you have to do is to add gasoline to get this powerhouse up and running.

In terms of power output, the model rates at 9,375 starting watts before settling at 7,500 running watts. All this wattage is backed by a 7.9 gallon and 420cc engine – with the result that you get 11 hours of runtime at 50% load.

Thanks to its six outlets, you can run all the heavy, on-site power tools as well as light industrial equipment. Its heavy-duty steel frame, meanwhile, reduces vibration and the resulting wear and tear. On the frame is the LED-lit control panel containing push-start buttons for startup/shutdown and fuel intake/block.

Key Features

  • 9375W starting and 7500W continuous power
  • 11 hours runtime at 50% load

15. A-iPower SUA12000E

Best RV Generator - iPower 12000W

Undoubtedly the most powerful generator of this review, the A-iPower is also one of the most expensive. Will it justify its price tag? Let’s find out.


As some of you could already guess, the lofty price tag of this model is because of its 12,000 watts starting power. Dropping down to 9,000 running parts during the operation, it is enough to supply electricity to a large-sized home.

Provided you’re running it at 50% load, this model provides 9 hours of run time – thanks to its 7 gallons, all-steel fuel tank. It also has a built-in filter to separate any impurities from the fuel.

Regardless of the terrain, you’re moving it on, the never-flat, improved-traction wheels provide ultimate mobility. Further adding to the convenience is the fact that all of its outlets are GFCI protected. There is also a USB adapter to let you charge your cell phone, with DC charging cables are also provided.

Giving the generator a clean look is its cord protective cover – which keeps all wires hidden – while also providing protection. Then there is the keyless one-touch push button which lets you effortlessly start the generator.

Key Features

  • 12,000W starting and 9,000W continuous power
  • 9 hours runtime at 50% load
  • 7 gallons fuel tank

Types of Generators

When you’ll visit the market, you’ll mainly come across three types of generators.

Home Standby Generator

Typically ranging between 5,000 and 20,000 watts, they automatically start when the power goes out. You might want a pro to install them because only an experienced electrician could help you with noise restrictions, municipal permits, and proper location.

  • Supply more power
  • All three choices of fuel – propane, natural gas, and gasoline
  • Self-diagnostic; let you know when they need maintenance
  • Pricey

Portable Generators

Best Generator for RV - Portability

Since they supply relatively less power than standby generators – between 3,000 and 8,500 watts – these units cost less and are easy to maneuver. Most portable generators run on gasoline, offer electric starting and are a cinch to maneuver.

  • Ultra-maneuverable
  • Less pricey than home standby generators
  • Provide considerable power
  • Battery required for electric starting may not be included in the package

Inverter Generators

Best RV Generator - Briggs Stratton Inverter

In case you are wondering, inverter generators are different from their conventional counterparts because they provide a constant flow of current – without any fluctuations. They are also quieter due to their sophisticated exhaust systems which help tone down noise.

  • Produce less noise
  • Run efficiently and consume less fuel
  • Have fewer emissions
  • Aren’t THAT powerful

Power Consumption and Number of Outlets of Generator

Starting with the power consumption, it depends on you.

For instance, if you want to run your air conditioner on the camp, then you’ll need a 4,000 watts + generator. Conversely, if your needs are basic – such as charging smartphones, powering up your laptop or using lights, a 2,000-watt generator should suit you just fine.

As for the number of outlets you may want in your generator, remember this rule of thumb: the more, the merrier. These are outlets from which the generator provides power to different sources – with the best ones offering as much as four outlets.

Conventional Vs Inverter Generator

Let’s compare both these generators on four counts:

Best Generator for RV - Fuel Consumption

  • Fuel efficiency: When it comes to fuel efficiency, inverter generators are the best because they adjust their power output according to the demand. That principle of theirs is in contrast to conventional generators which supply the same power at all times.
  • Noise: Inverter generators also tend to be quieter thanks to the presence of special engines, sound dampening technology, and special mufflers.
  • Emissions: Due to their sophisticated engines, invertor engines produce fewer That means that they are more environmentally friendly.
  • Power Supply: Despite all their abovementioned advantages, there’s a reason people aren’t buying invertor engine in droves: they supply relatively less power than their conventional counterparts.

Fuel Type

Depending on where you’re going to use your generator, deciding on the type of fuel you may want it to use is an important factor.

Not only is gasoline more budget-friendly, but it is readily available and cheaper than some other fuel types. Though these generators are anything but quiet.
As any mechanical engineer might tell, diesel engines are more fuel efficient than gasoline ones. However, since they don’t rely on spark-ignition, they aren’t an option for extreme winter conditions.
Provided you can carry propane cylinders with you, these generators will justify your decision by operating quietly and providing an indefinite shelf life.
Able to run on both gasoline and propane, they offer more convenience by letting you switch fuels when one of them isn’t available.
The most expensive of the lot, solar-powered engines have minimum running costs. That said, due to their huge upfront cost, an in-budget solar powered generator could only power your low-wattage devices.

Parallel Compatibility

In some instances, it might happen that the power supplied by one engine isn’t enough. Consequently, you’ve no option but to increase the power supply. One way you can do that is by installing two generators with “parallel compatibility”.

As experts tell us, most invertor generators offer parallel compatibility without saying it. However, if you’re going for a conventional generator, read its label to check whether or not you can connect it in parallel.

Run-time of Generator

As you might already know, the runtime of your generator is inversely proportional to the load you’re going to put on it. In plain English, this means that the greater the load, the shorter will be its runtime.

Runtime varies from one generator to another – with the best ones offering up to 16 hours of uninterrupted power supply on a full fuel tank. Still, if you’re on a budget, you could get budget models offering as much as 8 hours of run time.

Noise Level

As health experts tell us, noise levels greater than 85dB are considered to be harmful – which means they could damage your hearing on prolonged exposure. While a normal conversation occurs at 60 dB, the noise of a motorcycle engine is close to 100 dB.

That, in turn, means that your generator’s noise level should be less than 85dB. Fortunately for you, all four of our recommended generators – as well as most of the others in this review – fulfill this criterion. That means that if you select our recommendations, your ears won’t have to worry.


Best Generator for RV - Portable Generator

What is it that makes a generator portable? Generally speaking, portable speakers – in addition to being not bulky or heavy – have easy-to-move rubber wheels and adjustable handles. So you could move them around with ease.

Unfortunately, when it comes to power rating, portable generators fall behind in utility. That happens because highly-rated generators – which supply more powers – incorporate more parts. That, in turn, makes them bulky.

That means you have a problem in which you can either select a portable or a high-power rated generator, but not both.

How to solve this problem: Get two parallel compatible smaller generators. While they will provide double the power, you can move them around with ease at the same time.


Go through the abovementioned product reviews, and you’d see that the best warranty on offer on RV generators is 3 years. Anything above that is a bonus.

How to Install a Generator for Your RV

In case you wrong install a generator for your RV, you could damage not only the power converter but also the electronics.

Follow the following steps to install the generator correctly:

Step 1: Choose where to mount it

First of all, you need to decide the best placing place for your generator. Provided you’re using a travel trailer, the A-frame at its front – between the hitch and the propane tanks – is one place. Conversely, you can also place it on the rear bumper.

Step 2: Mount the generator

First, attach the platform of your generator to your RV.

If you’re mounting it to the A-frame, place U-bolts over the frame and through the mesh. Conversely, if on the rear bumper, put the U-bolts in the bottom of the platform after passing through the mesh. Afterward, secure the U-bolts around the support structure of the metal channel.

Second, select a suitable place on the platform where to place the generator.

Try to make sure that the weight of the generator is on the platform’s center. Afterward, secure it to the platform. If your generator has place bolts, use them to secure it.

Step 3: Wire the generator

You have to choose between two options when deciding how to wire it. Both of them differentiate on the automation they provide to your system.

If you want the simplest method, plug the shore power cord into the generator receptacle of your RV. Doing this will make sure your RV has shore and generator power at the same time. On the flip side, it will mean that you can only run the generator when the RV is static.

The other, slightly difficult method, is a transfer switch. It gives you the freedom to connect two AC Power’s sources.

To do this, all you have to do is to wire one side of the transfer switch with the generator’s AC output, before wiring the shore power to the other side. That gives you the freedom to switch between the two sources of power.

6 Safety Tips for using an RV Generator

Best Generator for RV - Fire Hazard

Follow the following tips to remain safe while using an RV generator:

  1. Never use an RV generator indoors – doing so might lead to the accumulation of Carbon monoxide which is a fatal gas
  2. Provided you have no choice but to install it indoors, install either plug-in CO alarms or battery-operated alarms. Remember, smoke alarms are NOT designed to detect CO
  3. Always direct the exhaust of your generator AWAY from the spot where you’re camping
  4. If you spill gasoline on hot engine parts, it can ignite. Therefore – and especially if you’re using a gas-powered generator, turn it off and allow it to cool before refueling it.
  5. Always store gasoline in a container approved by ANSI. Make sure you place the container in a well-ventilated place
  6. Never place your generator right next to the RV. If possible, maintain a distance of 15 feet between the two.


Whether you came here looking for a quiet RV generator – so that your neighbors don’t report you to the police – or want a powerhouse which could get the whole house up and running – while still boosting efficient fuel consumption – we have got you covered.

In case you are wondering, the one generator which we liked the most is the Westinghouse WGen7500. Not only does it provide a runtime of 18 hours – the biggest of any generator in this review. But this generator is also one of the quietest. Consequently, if you want the best of both worlds, check out the WGen7500.
