10. Honda EU2200IC Companion

Here we go – the younger sibling of the godfather of all portable inverter generators – Honda EU2000i.

Honda was the first company to introduce inverters to the market back in 1999.

Even now, nearly 20 years later, the original Honda EU2000i has been the most popular choice among professionals shopping for the highest quality generators.

Back in 2008, Honda replaced it with the newer, slightly more powerful model – EU2200i.

The EU2200IC Companion is one of the variations of EU2200i.

It’s the best choice for an RV as it has a built-in 30 AMP receptacle for RV.

Other than that, it offers the same capabilities and great design features as Honda EU2000i.

It is a super quiet generator. At 25% load, the noise level is only 49 dB!

Even at full load, the generator is very quiet.

It is one of the best choices for campsites.

It has an original Honda engine – the synonym of the best quality.

The finishing is very robust.

This RV generator is suitable for use in all kinds of rough circumstances.

I have personally seen the construction workers working in the mountains at high altitudes using this Honda generator to power the construction equipment they used to build the iron steps and ladders for trekkers and mountaineers.

That can give you a good idea of how versatile it is, especially for outdoor use.

The EU2200iC generator provides 200 more watts than its predecessor while keeping the same noise level and selling for the same price.

That’s perhaps not a revolutionary change, but it is certainly a nice improvement.

The Ultimate Guide to Choosing the Best Generator for RV

The first question you should ask yourself before buying the best portable generator to power your RV is:

How much power do you need?

You don’t want to purchase a portable generator just to realize that it’s too small to run anything.

By saying “small,” we don’t mean the actual physical size of the generator but its power output.

All appliances and electric equipment in your RV require a certain amount of power to run.

In the US, we usually use watts (W) or kilowatts (kW, 1kW = 1000 watts) as the basic units of measurements

E.g., a typical LCD TV would need around 120 watts to run. A refrigerator would require at least 180. A 15000 BTU RV air conditioner would consume about 2000 watts.

However, there is a little catch.

The appliances with a built-in motor require higher wattage to turn them on and run for the first few seconds. The amount of watts these devices need to kick in is called the starting wattage (sometimes referred to as surge or peak watts)

After a few moments, their consumption goes back to “normal.” That’s called running wattage (also known as rated watts).

Let’s have a look at the refrigerator again.

While an average RV fridge requires approx 180 watts to run, since it has a motor, it requires a much higher number to start. That would be around 600 watts depending on the model.

Therefore an RV refrigerator needs 600 starting watts and 180 running power watts to start and run properly.

As for the big 15,000 BTU AC unit – it would need, on average, 3300 starting watts and 2000 running power watts.

The following table lists the average wattage requirements for commonly used RV equipment.

Approx. Starting WattsApprox. Running Watts
RV Air Conditioning Unit (11000 BTU) 1600 1000
RV Air Conditioning Unit (13500 BTU) 2800 1800
RV Air Conditioning Unit (15000 BTU) 3300 2000
RV Refrigerator 600 180
Frying Pan 1500 1500
Microvawe Oven (800 Watts) 1300 1300
Laptop Computer 250 250
Hair Dryer 1900 1800
Satelite Receiver 250 250
Portable Fan 120 40
Lightbulbs (incadescent type) 60 60
LCD Monitor 30 30
Blueray Player 350 350
Flat Screen TV 120 120
Coffee Maker 600 600
Toaster 1200 800
Blender 850 400
Electric Grill 1650 1650

These two numbers: starting & running watts, are also the ones you should pay close attention to when shopping for a generator.

A portable generator needs at least as much peak power as the starting wattage of the most energy-consuming device you are planning to run OR the sum of the added starting wattage of all devices you want to connect.

Sounds complicated? Let’s have a look at a specific example for better illustration.

One of the most popular portable generators for RVs is Honda EU2200iC.

Its maximum power output is 2200 starting watts and 2000 running watts.

Would it be enough to run a large 15,000 RV air conditioner?

Such AC requires a starting wattage of 2000. That’s what Honda EU2200i can provide. So far, so good.

Unfortunately, this AC needs 3300 starting watts to turn on and run for the first seconds.

That is well above the maximum starting wattage output offered by Honda EU2200i.

So the final answer is – no. Honda EU2200i sadly cannot run a 15,000 AC.

Ok, but what if you have a smaller AC unit? Let’s say – an 11,000 BTU one?

On average, it would need 1600 starting watts and 1000 running watts.

As both figures are well below the maximum capabilities of Honda EU2200i – you could use it to run this air conditioner.

On top of that, you would still have enough spare power to run a couple of other smaller electronics such as a TV, computer, and a set of lights.

Ok, so by now, you should get a decent idea of how running and starting watts work. You also know to use these figures to determine what size of a generator do you need to power your appliances.

But what if your air conditioner or a refrigerator has got its power requirement written in amps? How do you calculate this?

Don’t panic as it is straightforward to convert amps into watts.

First, you need to determine the voltage of your equipment. In the US, the most common standard is 120V. Some appliances, however, may operate at higher voltages, such as 220V. If you are unsure how many volts your equipment uses, you should also be able to find out on its label.

Then use the following formula to find out how many watts it consume:

Wattage = Amps x Volts.

For example, if your equipment draws 20 Amps at 120 voltage, then its wattage would be:

20 x 120 = 2400 Watts

Which type of generator is the best for an RV?

You might ask yourself – Can I save myself a headache counting all these power requirements and get the largest portable generator?

Technically, yes. But trust us, that’s something you DON’T want to do.

That is for a few reasons.

Conventional open-frame portable generators are VERY LOUD.

Most portable generators are designed for two purposes – to be used at a construction site or as a backup stable power supply for homes or businesses during a blackout.

Those are the situations when the noise level is not such a significant nuisance.

Nobody cares about the sound a single portable generator produces with all this noisy construction machinery around.

On the other hand, when then the power goes out in the entire neighborhood, none of your neighbors are going to mind your generator noise level since they’re probably going to run them too.

But then imagine trying to run such a generator at a campsite.

It’s a beautiful summer night. You are enjoying the scent of crystal clear air.

You’re far away from the nearest big city.

There are no sounds to be heard except some quiet indistinctive chatter from somewhere far away.

Feeling peaceful and relaxed, you are ready to go to sleep.

You’re just about to hit the hay when suddenly, the loud noise destroys your peace.

The guy in the RV next door just turned on their portable generator to run the air conditioner for the night.

Oh god.

That’s it for the silent, peaceful night.

For the next couple of hours, you’ll listen to the lullaby of the portable generator engine running continuously until the early morning.

That guy who turned on their loud generator is now the perfect candidate for the title of the Most Hated Man on Camp.

You don’t want to be that man.

That’s why you should get the quietest generator possible.

We measure the generator noise level in decibels (dB). Any generator operating at higher than 60dB is already too loud for RV camping trips.

This FYI, is pretty much the case with ALL conventional portable generators.

That is why your only choice is a portable inverter generator.

You should also get one with at least 3000 watts, such as this Champion generator.

In this article, I’ve explained more about what inverter generators are and how they differ from conventional types.

One of the best things about them is that they are much smaller and lighter than ordinary open-frame portable gens.

They also have a few more essential features, which make them the only viable choice for RV.

Benefits of Portable Inverter Generators

1. Inverter Generators are much quieter

The quietest units operate in the 50 – 59 dB range, depending on the load.

That’s already silent enough not to ruin everyone’s night.

Inverters are by far the best portable generators for boondocking.

On the other hand, if you stay at the designated RV park, which explicitly prohibits ANY sort of portable RV generators from being run at night – sorry, you won’t get away even with the most silent of a generator.

That is unless you use solar generators like one of these.

Note that those usually provide only minimal output wattage.

You can’t use them to run an AC or a fridge unless you get the one with the highest output.

A power station can nonetheless be an excellent supplemental power source for an RV, suitable for powering RV batteries.

2. Inverters are the only safe choice for sensitive electronics

If you plan to live off the grid for a while, you will need a reliable power source to charge your phone or laptop.

Using a typical portable generator to charge one of these can easily damage them.

That’s because conventional generators run at higher levels of so-called Total Harmonic Distortion (THD).

The energy created by them is, therefore, less stable and clean.

While this is not a concern at all if you use them along with heavy construction equipment or big kitchen appliances – modern portable electronic equipment is much more sensitive.

That’s why we refer to tablets, phones, flatscreen TVs, etc., as sensitive electronics.

Inverter RV generators, on the other hand, are perfectly fine.

They usually produce less than 5% of THD, which is safe for your portable electronic equipment.

On top of that, inverters often come up with dedicated USB ports to make charging your iPads or Bluetooth speakers even easier.

3. You can use two inverters in parallel

Imagine that you already have a 2000 watt portable inverter generator. It works fine until day one, you realize you could do with more power.

Or perhaps you need a bit more powerful generator to use as a home backup supply.

What’s the best solution?

Buy another portable inverter generator with the same wattage and get twice the power.

Most quality inverter RV generators offer the so-called parallel capability.

That means that you can plug in two generators using a dedicated parallel kit.

By doing so, you can double the total energy output. More power to you!

Connect two Honda EU2200i generators, and you’re going to get 4000 running power watts at your disposal – more than enough to satisfy even the most energy-demanding RV.

Still not enough?

Get two Champion 3400 recreational vehicle generators, connect them in parallel, and voila – you’ve got a massive 6800 starting wattage at your hands.

I honestly can’t think of any RV which would require such high power levels.

On the other hand, that would be more than enough power to run the essential equipment in a mid-sized household!

Generally speaking, it’s a much better solution to use two inverters in parallel rather than one single conventional portable generator (Remember? Inverters are safe for portable electronics and are much quieter).

Who makes the best portable RV generators?

When it comes to the market of portable RV generators, there are a few brands that stand out.

In our opinion, Champion makes the best generators for RV and camping.

They have released an excellent 3400 watt RV ready inverter generator that regularly receives rave reviews from RV enthusiasts.

You can connect it to your trailer without having to buy any adapters or extension cords.

It’s a dual-fuel RV generator – you can run it on either gas or propane.

That would save fuel and money, reduce dependence on one fuel source, and give you longer runtime.

If you’re looking for a smaller 2000-watt generator, I’d recommend the WEN 56200i.

WEN is a fast-growing generator manufacturer that took the US market by storm in recent years.

They make reliable portable generators selling only for a fraction of the price of most competitors.

56200i is living proof that a quality portable inverter generator does not have to cost a fortune.

It has the same capabilities and performance features as much more expensive generators.

It’s also a remarkably quiet generator.

You simply can’t beat the price either.

That makes it an optimal choice for those looking for a reliable and silent 2000-watt generator for RV camping and who don’t want to spend a little fortune on one.

How Do You Connect a Generator to an RV?

There are at least two highly recommended generators that you can hook up to your RV straight out of the box without having to purchase any additional adapters.

These are Champion 75537i and its slightly stronger dual-fuel cousin – Champion 3400 dual fuel inverter.

Both are excellent choices for RV and are clearly among our favorites.

For most of the other generators, you would need the RV adapters.

Fortunately, those are very cheap and easy to find online. Just make sure you get the right type!

2000-watt and 3000-watt inverters require similar adapters to connect to the power cord.

What makes the difference is the amperage of your power cord.

Cords are usually rated at 30 or 50 amps.

You can quickly tell the difference between a 30 amp and a 50 amp power cord by counting the number of “male” power prongs.

Three male power prongs = 30 amp.

Four male power prongs = 50 amp.

Simple as that!

Onwards to the right types of adapters.

Additional Things to Look For When Buying a Generator for an RV

When considering which generator you want to buy, it’s important to know which features you should look for and what’s recommended for each of them. Not only do you want to ensure that you get something that can power your RV batteries and other appliances, but you also want to find something that’s built in a way that reduces the number of issues you might encounter.

Keep in mind that these features are the most common and usually the most important, but there are other additional features that different generator models might have. The most important thing is to just look at all of this information and compare it to the generators you’re considering to ensure they’ll meet your needs.

Power Output (Wattage)

One of the biggest things people consider when buying a generator for their RV is how much power output or wattage they need.

This feature is essential as you want to make sure your RV can run smoothly. It gets a little confusing when you consider that different-sized RVs will need different amounts of power.

You’ll want to consider a few things to find the amount you need. For starters, figure out which appliances are 120V and add all of them together.

You’ll also want to ensure you get a minimum wattage equal to your air conditioner because these use the most power.

Next, multiply the total volts and amps to get the amount of wattage you need.

This amount is the minimum you need, so you might want to get a little extra to ensure you can power any additional appliances you might end up using.

Depending on what type of generator you plan on using, there are some things you’ll want to install.

For example, a generator that will be built right into the RV can have a transfer switch installed.

This switch will automatically switch the generator on and off, depending on whether or not you’re connected to the electricity grid.

Not only is this much more convenient, but you’ll be able to plug in any appliances or accessories when you need to instead of having to wait until you’re connected to electricity or needing to stop to turn on the generator manually.

Noise Level

You’ll also want to consider the noise level that the generator puts out. It might not seem like a big deal, but it’ll be essential, depending on where you’ll be camping.

For example, many campsites have strict noise regulations after a specific time, so having a loud generator could end up getting you kicked out or having to pay extra fees due to breaking the rules.

The majority of generators that you’ll see will have a decibel rating that lets you know how loud it is.

One thing to consider is that for every 10-decibel increase, the noise is ten times louder.

For example, a generator that is 70 decibels will be ten times louder than one that has 60 decibels.

If at all possible, you’ll want to find a generator that runs between 49 and 65 decibels, which is about as loud as a normal conversation.

If you can’t find a good generator within these decibels, you could get away with having one that’s a little louder.

Once you reach around 110 decibels, though, you’ll have a noise level similar to the sound of a running chainsaw.

If you already know where you’ll be camping or driving, see what kinds of regulations they have to ensure you have a machine that falls within those guidelines.

Fuel Economy

Since fuel can be quite expensive in different areas, it’s important to know what kind of fuel economy your generator has.

Not only will this ensure that you aren’t going to blow through your fuel budget, but you’ll also be able to figure out how long you can run your generator before needing to fill it up again.

Generators with more power output will consume more fuel.

In the same respect, the more you run the generator, the more fuel it consumes.

Since there’s a chance that you won’t use the generator the same way every time, it’s essential to calculate the average amount of use you’ll have.

Another thing to remember is that different fuel types will burn differently.

For example, a 4,000-watt diesel-powered generator will go through about 1 gallon of fuel per hour at full load.

On the other hand, running the same generator at a 50% load will result in using about 1 gallon of fuel every 3 hours.

Regardless of how you plan to use your generator, ensure you’re looking at all of this information to ensure you have a big enough budget to keep fuel stocked up.

Design Quality

The quality of the design is essential. Not only do you want to ensure that the generator is made of high-quality materials, but you also want to make sure it’s built in a way that can help it withstand a lot of wear and tear.

With that being the case, there are a few things to consider.

One of the biggest things is that everything is secured where it needs to be. The last thing you want is some parts being loose and causing other parts to get disconnected or interfere with each other to create a dangerous situation.

Another thing to look for is whether or not it has an enclosed frame. An open-frame generator is at a higher risk of water or other elements getting in, causing it to stop working.

One last thing you want to look at is whether or not it’s made with strong materials like metal, which will help ensure it can withstand most situations.

Weight & Portability

Most people will end up using a portable generator instead of one that’s built into the RV. With this being the case, it’s important to consider the weight and how easily you can move it.

When looking at weight, you want to find a generator with the wattage you need while being light enough to move around. The issue here is that the ones with a higher power output tend to weigh at least 100 pounds.

Not only is this hard to move around, but those using the RV alone might find that they have issues.

The weight of the machine should be right on the box or in the item description, which means you’ll know the information before you even buy it. A lighter generator will be a lot easier to move.

Remember that many of the newer inverters will provide you with higher power output without all of the extra weight added.

Warranty & Customer Service

One final thing to consider is the warranty and customer service. Since you never know what might happen while you’re on the road, it’s crucial to be able to use a warranty and reach out to the company without any issues.

Before purchasing, look at reviews to see how customer service usually responds and make sure you know every detail of the warranty and what’s covered under it.

Which Fuel Should You Use?

For the most part, generators are going to run on three types of fuel: diesel, gasoline, and dual fuel (gas and propane). While most will also be able to plug into an electric outlet, riding in an RV means there will be times when you won’t have access to one of these, and you’ll have to use the fuel.

Each of these has its benefits and setbacks, which we’ll talk about next. Once you get more information on each fuel, you should be able to figure out which one will work best for your needs and which kind of generator you need.

What are the most common fuel types for RV Generators


Gasoline is the most common type of fuel used for generators, mostly because it’s so widely available. The cost tends to be cheaper than other alternatives, which means you can get more for the same amount of money. The good thing is that you can go to the gas station with a few gas cans and fill them up. Keep in mind, though, that there’s usually a limit by the government on how much you can store because it’s so flammable.

Another thing to remember is that it’s only good for around one year before it goes bad, so those who have been storing it for a long period might find that they can’t use it anymore. On the other hand, those that will only be storing it for a short period of time should be fine. You should also remember that the supply can be scarce if there’s some kind of emergency because everyone is buying it up.

  • Gas is usually pretty easy to get
  • A gas generator is the cheapest and most readily available type
  • Gasoline can be easily stored
  • Very easy to refuel the generators
  • Gas is only good to store for around one year
  • There’s a limit to how much you can store at one time
  • Gasoline can be hard to get in the event of a serious emergency
  • Gas-powered generators are not the most cost-effective solution
  • Gas is a fossil fuel with a negative  environmental impact

Dual Fuel (Gas/Propane) – Best Choice

The most common fuel type for RV generators are ones that use more than one. The most commonly used dual-fuel generators run on either gasoline or propane. Not only does this give you the option to use whichever one you want, but you’ll have to refill fewer times because you have both fuel types.

It’s also cheaper to run a generator on propane.

The best dual-fuel generator will give you a longer run time and decrease your dependence solely on gas, saving money in the longer term.

  • You can easily switch between gas and propane
  • The most cost-effective solution – propane is cheaper than gasoline
  • More environmentally friendly than diesel fuel or gas-powered generators
  • Longer run time – you won’t have to refill the fuel as much as you would with one fuel type
  • Propane tanks are heavy to carry around
  • Some places might not have propane readily available
  • Dual-fuel generators are slightly more expensive to buy than conventional gas-powered generators


Diesel is a very stable fuel with a lot less chance of being explosive than other fuels, like gasoline. It has more energy than most other fuel types, and machines that use it are a lot easier to maintain as a result of not containing spark plugs. There are a few ways you can stock up on diesel. The first is filling cans and storing them in a specific place. The other way is by having a tanker come and fill up an external tank that you can use to fill up your generator whenever needed.

However, portable diesel generators are slowly going extinct these days. That’s mainly due to their bad environmental footprint, outdated design, and large size.

You will have a hard time looking for a decent portable diesel generator for your RV.

That’s why we recommend either gas-powered or – the best choice – dual fuel generators instead.

  • There’s more than 1 way to get and store the fuel
  • Less flammable than other fuel types
  • It has more energy than other fuels
  • It can be quite expensive
  • Diesel generators are usually very heavy and bulky types
  • Least environmentally-friendly choice

Frequently Asked Questions About Generators for RV

What size generator do I need to run my 30 amp RV?

A 3,000-watt generator can run a 30-amp RV quite smoothly. With that said, though, you should try and calculate how much you’ll use and make sure that it will be enough.

A 3400 Watt generator like this Champion generator would be the ideal size for most RVs.

Will a 3500-watt generator run my RV?

A 3500-watt generator should be able to run a 30-amp RV smoothly. With this power output, you should be able to run everything at once without too many issues. That includes a 13,500 BTU AC and refrigerator.

Can you run a generator overnight?

Yes, as long as you have enough fuel to keep it running. Keep in mind that some areas might have restrictions on how long you can run your generator, so make sure you get that information.

What is the difference between surge watts and running watts?

Running watts are the amount of power required to continuously run your appliances, while surge watts (also known as peak watts) are the amount of energy needed to start large appliances. You’ll want a generator that can easily handle both load requirements simultaneously.

What’s the acceptable noise level for RV generators?

While it’s going to depend based on where you’re staying, almost everyone agrees that a noise level of an RV generator shouldn’t exceed 65 dBa. This decibel level is about as loud as a vibrant conversation or an idling car engine.

How to start an RV generator?

That will vary greatly depending on what kind of generator you have. Some have to be started by pulling a starter cord, while others require you to turn on a switch. We’d recommend using a generator with a remote start like the Champion 3400.

What’s the Best Fuel Type for RV Generators?

The two fuel types used in the best portable RV generators are gas & propane. Not only is such a unit more cost-efficient, but also more flexible since it gives you a choice between gas and propane. You will also get a longer total continuous run time from a dual-fuel generator.

Can I Run a Generator While Driving?

If you’re using a portable generator, the answer from a purely technological point of view is “yes”. However, in most cases, it’s not recommended.

Here’s why: running a generator while driving can be dangerous for you and other drivers. It also voids the warranty on most generators. So, if something goes wrong, you could be stuck with a hefty repair bill.

If you absolutely need to use a generator while driving, make sure to follow these safety tips:

– Only use generators that are designed for automotive use.

– Make sure the generator is properly mounted in the vehicle.

– Never run the generator inside the vehicle—this can create deadly carbon monoxide
