Top 5 Best Inverter Generators for RV

01 CHAMPION 4000-Watt DH Series Inverter (Editor’s Pick)

CHAMPION 4000-Watt RV Ready DH Series Open Frame Inverter

Why It Stands Out to Us

With a name like ‘Champion,’ no wonder this one takes the first spot in our review. Don’t worry, we haven’t picked it just because of its name. This 4000-watt inverter is powerful and operates quietly as well.

That’s not something you can say for many open-frame generators in the market. It’s also quite light and gives you clean power. That will help protect whatever you’re powering with it and is absolutely safe to use with sensitive gadgets.

Our Experience with the CHAMPION 4000-Watt DH

  • We took this one for a spin in our RVs and were pleasantly surprised how long it kept running. With a full gasoline tank, it managed around 17 hours of backup. That’s superb for full-time RVing.
  • All those hours were also quiet. Thanks to its innovative open-frame design, it wasn’t too loud. Of course, it’s an inverter. So, it isn’t whisper-quiet. But for what it is, this beautiful work of machinery’s low noise levels impressed us.
  • Our RVs didn’t become bogged down either. Since the inverter is light, driving around was a breeze. And when you’re RVing on open roads, a lighter option is always good to have. For those wondering, it’s 20% lighter compared to other inverters!
  • At times when we needed more power, we were easily able to connect it with another one to get some extra power since this inverter is parallel ready.
  • All that power can be tamed as well. We loved the economy mode this one has. This lets us run it in a low-power state, which we are sure will save some cash in the long run.
  • We installed this inverter into our RVs and took it for a spin to make sure we take it through its paces. And we are happy to say it held up perfectly during long strenuous use and provided reliable backup for our devices and the noise wasn’t much of a bother.

What We Didn’t Like

  • Although it’s quite light, there are no wheels in the package.

Who Is It Great for?

  • This one will be suitable for anyone who needs a solid and reliable inverter to power through long commutes. And the cool features like quiet operation, economy, and parallel modes are just the cherry on top.

What Could Be Improved and Why

  • Including some transportation wheels in the package would bring the whole thing together nicely. It would make it much easier to move this inverter around.

Our Recommendations

  • Get this if you want a reliable and continuous power source when RVing. Users who love some peace and quiet and want to save some can use the economy mode.


  • Brand: Champion
  • Wattage: 4000W
  • Running Wattage: 3500W
  • Engine Type: Four Stroke
  • Runtime: Approximately 17 hours


  • Long and continuous operation
  • Supports parallel operation
  • High wattage
  • Economy mode
  • High fuel capacity


  • No wheels included

02 Honda 662220 EU2200i Portable Inverter Generator (Also Best)

Honda 662220 EU2200i 2200 Watt Portable Inverter Generator

Why It Stands Out to Us

We don’t need to introduce Honda, do we? They are a legendary brand that’s known for their quality and reliability. So, it’s no surprise their inverter easily takes the runners-up spot. We loved how small and compact this thing is.

Don’t mistake compactness for lack of power, though. With 2200 watts at its disposal, this little guy can dish out some serious punches. The startup is fairly easy, too, thanks to the automatic decompressor.

Our Experience with the Honda 662220 EU2200i

  • Not everyone needs a big honking inverter for their daily needs. This one served us well, thanks to its small size and adequate power. It reliably provided backup power when needed and worked with all types of devices.
  • Carrying it around was a breeze. That also comes down to just how compact it is.
  • Noise levels were low, and we didn’t feel it was unnecessarily loud either. A quiet operating inverter is one of those things you don’t know you missed till you use one. And after having experienced it ourselves, we sure can’t go back.
  • Just like the previous one we tested; this inverter supports parallel power too. When we needed a little bit of extra oomph, we easily connected it to another inverter and called it a day.
  • Another thing we loved is the runtime. It isn’t as high as others but managed between 4 to 9 hours of continuous use. Nothing we can complain about.
  • That runtime didn’t cost us extra money either during times when we didn’t need to run it at full throttle. The economy mode came in handy. We ran it in fuel-saving mode. Over time, this will save you quite a bit of cash.
  • This inverter held its own and provided all the power we needed for backup during road trips and general use. The runtime wasn’t as long but it was still good.

What We Didn’t Like

  • Honda is a premium and well-known brand. So, it isn’t that much of a surprise this particular inverter comes at a price premium. But for the right user, the price should be worth it.

Who Is It Great for?

  • This one suits for people who don’t need monstrous amounts of power and would rather have a compact, quiet, and reliable inverter. If you want to run your mobile devices, TVs and microwaves in your RV, you’ll feel right at home with this one.

What Could Be Improved and Why

  • A lower price would make this one a fantastic buy.

Our Recommendations

  • When buying it, keep an eye out for any discounts or rebates you can get. That should soften the blow a bit. Regardless, you won’t regret buying this one. Just make sure to keep it well-maintained.


  • Brand: Honda
  • Wattage: 2200W
  • Engine Type: 120cc GXR
  • Runtime: 4 – 9 hours


  • Small and compact
  • Adequate power despite its size
  • Respectable runtime
  • Fuel-efficient mode
  • Quiet operation


  • A bit expensive

03 WEN 56225i 2250-Watt Portable Inverter Generator

WEN 56225i 2250-Watt Gas Powered Portable Inverter Generator

Why It Stands Out to Us

The crown for the ultimate quiet operation goes to the WEN 56225i gas-powered portable inverter. It’s fantastically quiet with a noise level of only 53 dB.

Other cool features like auto shut off, 5V USB ports, and the clean power it produces together make it another top-notch inverter to choose from.

Our Experience with the WEN 56225i

  • The wattage of this one is 2250 with a running watt of 1800. That’s good for low-demand tasks, and we didn’t need much power during our camping trips. So, it wasn’t a major problem.
  • One cool thing we loved, though, is the clean power it produces. Many campers take their electronic devices and other powered accessories with them and so did we. And it worked like a charm with those. We weren’t worried about them being damaged.
  • And then you have the low noise operation. Let us tell you one thing, we had a good time while the inverter ran quietly in the background. With 53 dB of noise, it’s a very quiet unit and an unobtrusive one. Big points for that.
  • All isn’t rosy, though. The fuel tank is a little too small. That means we needed to refill it in short intervals. You can only go so far with 1 gallon, which this one has. If that’s something you aren’t worried about, and the quietness is most important, you will love WEN’s inverter.
  • Its fuel tank might be small, but one feature helps improve the issue a bit. The fuel shutoff mechanism allows it to make the most of the fuel even in the carburetor. It will use all the remaining fuel before it finally shuts off. Not bad for a 1-gallon unit.
  • Some of us from the team took this inverter along with our RV to a meetup. We are glad to say the noise levels were very low and there weren’t any weird looks from others in the meetup. It’s safe to say this one passed the quite test with flying colors.

What We Didn’t Like

  • It’s obvious, isn’t it? As quiet and clean as this inverter is, the fuel capacity was a pain point for us during testing. Sometimes you just want to fuel your inverter and forget about it. That’s something you can’t do with this one.

Who Is It Great for?

  • Users that want the utmost peace with one of the quietest inverters around when going on long road trips will love it. If you know anything about RVing, you would know about RV clubs and meetups. This will be an awesome choice for those scenarios since you won’t disturb others.

What Could Be Improved and Why

  • The fuel capacity is one of its most glaring issues. A higher fuel capacity will make it a great buy.


  • Brand: WEN
  • Wattage: 2250W
  • Running Wattage: 1800W
  • Engine Type: Four Stroke
  • Fuel Tank: 1 Gallon
  • Noise: 53 dB


  • Very quiet
  • Clean energy
  • Fuel efficient
  • Parallel operation


  • Small fuel tank

04 WEN 56235i Super Quiet Portable Inverter Generator

WEN 56235i Super Quiet 2350-Watt Portable Inverter Generator

Why It Stands Out to Us

WEN managed to secure another spot in our review. This time for its compactness. With a very lightweight body that weighs a mere 39 pounds, you can carry this inverter easily all by yourself. Even with just one hand if you want to flex a little!

Other features like USB ports, fuel economy settings are also present. So, it isn’t a one-trick pony. But keep in mind the fuel capacity is also low here, though. It’s the same 1-gallon affair.

Our Experience with the WEN 56235i

  • Even though it’s pretty lightweight, we didn’t feel it lacked any power. Of course, we didn’t put it through high demanding tasks as we did with the first one. But with 2350 watts of surge power and 1900 watts of running watts, it did give us a good backup.
  • The backup power was clean as well. Connecting our sensitive devices and other electronics didn’t seem to be dangerous one bit.
  • And, of course, we loved how easy it was to carry around. You just can’t argue with the numbers. At only 39 pounds, we didn’t face any problem moving it from one place to another. However, we didn’t move it too much just for the sake of it. But it was still fairly easy for the most part.
  • Perhaps, one of the reasons it’s so light was the need for an external ground separator. We needed to buy it separately, and that left a bit of a sour taste in our mouths.
  • Another cool thing is the low operation noise. It certainly doesn’t match the 56225i but still holds its own.
  • Since the inverter is portable and small, we think it’s better for not-too-large RVs. It will fit quite easily inside (hopefully) and thanks for the product being lightweight, you won’t have a hard time moving it.

What We Didn’t Like

  • Having to buy an external ground separator seems like an unnecessary hassle we needed to go through. This is something the manufacturer could have easily avoided. That being said, we don’t think it’s a deal-breaker.

Who Is It Great for?

  • Travel enthusiasts who may not have a lot of helping hands around will love this inverter for their RVs. RVs are by nature meant to be mobile. With this inverter, you won’t bog yourself down. Powering up your devices and appliances or relocating it to somewhere else will be a walk in the park.

Our Recommendations

  • Get the external ground separator for it right when you buy. That will save you some trouble later on.


  • Brand: WEN
  • Wattage: 2350W
  • Running Wattage: 1900W
  • Engine Type: Four Stroke
  • Weight: 39 pounds


  • Super lightweight body
  • Ample power for most users
  • Clean energy
  • Fuel efficient
  • Adequate runtime


  • You need to buy the external ground separator separately

05 Champion 3400-Watt Dual Fuel Portable Inverter Generator

Champion 3400-Watt Dual Fuel RV Ready Portable Inverter Generator

Why It Stands Out to Us

Sometimes, two really are better than one. That’s why we have another Champion inverter with the best parallel operation in the market right now. This has 3400W of power for all those demanding RV trips.

Easy startup and quiet operations are impressive as well. And unlike the first one, wheels are included!

Our Experience with the Champion 3400 Dual Fuel RV Inverter

  • What good is an inverter that won’t give you the backup you need? Thankfully, we were able to pair this one up seamlessly with another unit when we desperately needed more power. Other inverters have this feature as well. But those don’t do it quite as well as this one.
  • Noise levels were adequately low. At 59 dB, it isn’t whisper-quiet but also didn’t annoy us.
  • The power this inverter provided to sensitive electronics like our phones and tablets was clean and reliable. That’s another bonus since we didn’t have to worry about those getting damaged.
  • Speaking of powering devices, there are a lot of outlets. We simply used those to power our devices, and that was just as easy as you would imagine.
  • We love choices around here. And the ability to use both propane and gasoline with this inverter is a level of versatility that we surely appreciated. Having the right fuel to run this thing was never an issue.
  • The startup was easy, thanks to the electric startup with a 3-position ignition switch. All the controls were in one convenient place, which meant we didn’t need to fiddle with it too much.
  • The runtime was impressive also. One thing we noted is there is a difference in runtime depending on what fuel you use. With gasoline, it goes for 7.5 hours. If you choose to power it with propane, then the runtime is an impressive 14.5 hours!
  • A trip with more than 4/5 people means there are a lot of devices to power. Then you have the TV and other appliances in the RV as well. Thankfully, this did a great job of providing extra power with its parallel operation.
  • And there are wheels included! That made it super easy to move around.

What We Didn’t Like

  • It’s a high-quality product with lots of cool features and thus comes with a high price tag. You can find other 3400-watt inverters for lower. But we don’t think those will give you the same experience and it’s a bit heavy too.

 Who Is It Great for?

  • Some heavy-duty appliances like washing machines, refrigerators and TVs in RVs can require a lot of power. If you have lots of devices in your RV, you may need a tad bit more power compared to others. That’s where this one will come in handy for you with its superb parallel operation capabilities.

Our Recommendations

  • Get this one if the parallel operation is very important to you. You will love the household ports and the clean power it produces. Yes, the price is a tad bit too high, but the quality is there to justify it.


  • Brand: Champion
  • Wattage: 3400W
  • Running Wattage: 3100W
  • Fuel: Gasoline and Propane
  • Runtime: 7.5 hours (Gasoline)/14.5 hours (Propane)
  • Wheels: Yes


  • Supports both propane and gasoline
  • Clean power
  • Easy to start
  • Excellent parallel operation
  • Fairly quiet


  • A bit expensive
  • Heavy

Best Inverter Generator for RV – Buyer’s Guide

Portable Inverter Generator for RV

1. Power Output

Determining the wattage output is a crucial thing to consider while buying an inverter generator. If you don’t get the correct one, none of your appliances will work properly, and you don’t want that!

Inverter Generator for RV

Some appliances such as an air conditioner or microwave will require a higher amount of power to run. And if you are planning to use these devices on your RV regularly, you need to buy your generator according to that!

2. Noise

If you want to enjoy quality time, you wouldn’t want annoying noise around you all the time! And one of the most incredible things about inverter generators is that they tend to be quieter than traditional generators.

Usually, these advanced generators will make noise between 50-60 decibels which is tolerable. However, sometimes the noise output depends on the load you put on the generator. So, you got to be careful about that.

While buying this machine, carefully read the labels to make sure if it will run silently or not. Moreover, you need to maintain your RV properly as a damaged one can make terrible sounds; there is no doubt about that!

3. Portability

These inverter generators come in different sizes. Some are portable but may not provide enough power or watts. It’s a balancing act between the two. Here you need to evaluate what you need more of.

So, if you are planning to move your generators from one place to another, you need to get a lightweight device. In this way, you don’t have to throw your back out every time you try to transport it.

However, when looking for a heavy-duty generator, make sure that it comes with a transportation handle. Therefore, while lifting the whole thing, you will have something to grab, ensuring better safety for you.

4. Fuel Tank Size

The fuel tank size is one of the two main things determining how long the machine will run. Another reason is how much load you put on it.

Larger fuel tanks make sure that your inverter generator runs for a longer time. And the smaller ones will run out of juice pretty quickly. But you should know that generators that come with a bigger tank will be much heavier.

So, if you prioritize longer runtime than portability, you can go for the machine that can hold a significant amount of fuel; it is totally up to you.

5. Fuel Type

a) Gasoline

Though gasoline is one of the most common kinds of fuel, it isn’t cheap at all. However, you will find it anywhere, which is a relief, to be honest.

b) Diesel

Diesel is one of the most efficient options as it runs longer than gasoline. But while burning, it smells, and the generator makes a pretty loud noise, which is a little disappointing.

Moreover, machines that run with diesel are rare to find. So, if you don’t want to struggle, you should go for a more effortless option.

c) Propane

Propane is getting popular these days as a fuel option for inverter generators. It’s more efficient than diesel or gasoline, which is another reason behind its rising popularity.

d) Dual-Fuel

Some dual-fuel generators run on both gasoline and propane. These machines are handy as you can use whatever fuel you prefer and save some money from time to time.

However, these generators are pretty expensive than the ones that run with one particular oil. If you can deal with the cost, getting the dual-fuel one will be the most brilliant idea.

6. Build Quality

The ideal RV generator will be lightweight and compact. But it should be sturdy, as you would want it to be durable. So, while getting your generator, make sure that they come with these features so you can enjoy the most excellent service.

7. Fuel Efficiency

Your RV will require a different amount of fuel on different occasions. Therefore, you should be able to control how much energy you use each time. It will allow you to save money and the environment at the same time.

8. Parallel Capability

When your generator comes with parallel capability, you can connect to another one to increase its power. If one inverter generator is not enough for your RV, you can connect two of them for a better experience.

So, if you want to run a larger air conditioner unit or something like this on your RV, you should go for a machine that comes with parallel capability. In this way, you can enjoy greater benefits.

9. Warranty

The more extended the warranty period, the better the experience. It would help if you went for a device with a 1-3 year long warranty period; hence, you won’t have to worry about any repair costs at all.

10. Price

It is pretty evident that you will need to get something that comes within your affordability. Well, if you set your budget from $100-$500, you will get an excellent generator that will offer you a fantastic service.

Safety Protocol When Using an RV Generator

When you are using an RV generator, you need to be careful about Carbon Monoxide poisoning. Every year we people die from it, so you have to take precautions to prevent this accident.

As Carbon Monoxide is odorless and colorless, you won’t feel its presence until it is too late. And here are the reasons that can cause this problem.

  1. When your gas-powered heater doesn’t work correctly, it can end up creating Carbon Monoxide.
  2. Exhaust from vehicle engines or another generator is also another cause.
  3. If someone else’s vehicle is parked near your vehicle and emitting CO (formula of Carbon Monoxide), you can get affected, as the fume travels faster.

Here are the safety protocols you can follow while using an RV generator –

  • Before you start using the generator, make sure that the exhaust system is working correctly. Always avoid using a faulty machine if you want to be on the safe side.
  • Inspect the oil and fuel level before turning on the generator.
  • If you have a gas-powered device, follow the instruction manual carefully.
  • Read the labels on the generator; you may find out something that will help you maintain the machine perfectly.
  • When there are other vehicles parked near your RV, you should keep the windows and vents closed. In this way, the exhaust from other generators won’t cause any harm to you.
  • While cooking in your RV, you should use a range fan or keep the windows open to maintain proper ventilation.

The Symptoms of Carbon Monoxide

If you have enough knowledge about the symptoms of CO, you can take the necessary steps to prevent further loss. The symptoms are,

  • Muscle twitching
  • Nausea and vomiting
  • Dizziness and headache
  • Throbbing pain in the temples
  • Physical weakness

When someone around you feels these symptoms, you should immediately take them outside and seek medical attention. And you should shut the generator off as soon as possible.

Frequently Asked Questions

1. How much power do I need for my RV/Camping?

The amount of power you need for an RV depends on your air conditioning unit. If you have a sizeable air-conditioning system, you need more power than the regular ones.

So, it would be better if you get a generator that has minimum Wattage equivalent to your air conditioner’s starting Wattage. In this way, you can ensure that everything will be running smoothly.

2. How long will an RV generator run?

A portable generator usually runs for 8-20 hours, depending on the appliances you are using. And if you want to get the best results, you should maintain the machine’s top-notch condition.

3. Can I hook up multiple generators at once?

If your generators come with parallel capability, you can connect several of them to create more power. This feature comes in real handy when you need to generate more power to turn on several devices simultaneously.
