Honda EU 3000is: Best Fuel Efficiency

Summary & Features

Honda is a top player in the industry and is known for consistently producing quiet, easy to operate, high quality, reliable inverter generators for RV use or other. The Honda EU 3000is is no exception. 

This 3000 watt 120V portable inverter generator is an excellent power source for RVs. It can power a 13,500 BTU air conditioner and many common household appliances.

Possibly what people love most about this generator is that it runs a whopping 20 hours on 3.4 gallons of fuel. You won’t have to worry about it crapping out overnight. This is all thanks to the exclusive Eco-Throttle System. 

Another standout feature of the Honda EU 3000is is that it’s super quiet and projects less noise than a normal conversation (you neighbors will thank you!) Specifically, it operates at 49 to 58 dB(A), making it ideal for camping in parks. 

Honda built this generator to treat your more sensitive electronics well. The advanced inverter technology provides stable, reliable power to charge your laptop and not fry it. 

Want to add more power? Add a second EU3000is! Keep in mind that you will have to purchase the cable separately to parallel it. 

In terms of safety, you can be at ease knowing that the CO-MINDER Advanced Carbon Monoxide Detection System is continuously monitoring carbon monoxide levels. It automatically shuts down the generator before detected CO levels near the generator become dangerously high.

If your oil is low, you are protected by Oil Alert. The generator will shut itself off when it is low on oil. Additionally, it is circuit protected, so the generator doesn’t get overloaded.

Keep in mind the Honda EU 3000is is a full 144 pounds. So if you’re not a gym rat, I would suggest purchasing the 2 or 4 Wheel Kit, so it is easier to remove. There is also an optional cover to keep it dry and protect it from the elements. It would not be a bad idea to purchase either of these accessories. 

Last but not least, Honda offers a three-year warranty, so you are covered.

Heading out for a road trip with the family in your new RV?

Getting the best generator for RV is necessary to ensure your comfort and peace of mind while on the road. This means being able to power Sally’s hairdryer and David’s gaming laptop while mom sits under the AC.

There are tons of options on the market for camping generators. Some good and some…not so good. Lucky for you, we already did the homework on RV generators, their usage, and finding the best ones. There’s no need to worry about the fuel consumption, gas or propane, a power supply, or how to power your RV – this guide will cover it all.

Here we provide an extensive review of the best RV generators, important things to consider before investing in the best RV generator, tips for taking care of the best RV generator, some frequently asked questions, and much more.

Benefits of Having a Generator in Your RV

Today’s RVs are loaded with the amenities of home. We have come a long way from when all you had were a few lights powered by a built-in battery! Given these modern advancements, more and more people own an RV/camper with a generator. 

Generators are a practical solution for life on the road and make your every day more comfortable and convenient: 

  1. You can plug in without a second thought. Run the air conditioner, microwave, and vacuum at the same time. 
  2. You will not have to rely on where the next campsite is continually. You are free to be off-grid and wander.
  3. If there is a power outage in the area, you won’t have to suffer.

Things To Consider Before Purchasing a Generator

Built-In Vs. Portable

Indeed, most RVs come with a built-in generator. Built-in generators are certainly the more convenient option of the two as they are hardwired to your RV’s electrical system, and the fuel comes right from your RV, so you don’t need to refill a separate tank. 

Many people choose built-in generators because they are often more powerful than portable generators and easier to use. However, professionals should install and maintain them; they cost quite a bit more, are not discrete, and have a high risk of exhaust leaks.

Portable generators, on the other hand, are better for smaller RVs. Many people choose them because they are discrete, less expensive, more efficient, can be placed away from your RV, and you can easily service them.

If you want, you can have both a built-in and portable generator, so you will always have a backup. 

Keep in mind that because portable generators are light in weight and easy to transport, people steal them often. If you purchase a portable generator, you should consider investing in security to chain it in place.

Power Output

Before purchasing a generator, you will need to calculate how much wattage output you will need. You can do this by determining how much energy each of your RV appliances uses and adding it up. 

Most generators expend between 2000 and 4000 watts, so make sure your RV appliances stay within that range.

The Honda wattage calculator is a tool that can help you calculate your exact wattage needs.

Keep in mind, if you have too much power, it could blow the circuits, and if you don’t have enough, you can’t use your fancy RV appliances. Devices such as microwaves, hairdryers, and air conditioners use a surprising amount of power!


Low noise is a significant feature in a generator, especially if you want to spend a lot of time camping in areas where there are other people. External generators are prohibited during quiet hours in an RV park and can be a real nuisance to you and others if they are loud. 

Therefore, make sure to be conscious of your noise level.

Parks will let you know their regulations for decibel levels and distances. In most places, the limit is up to 60 decibels at a 50-feet distance.

Fuel and Fuel Consumption

Generators are fueled by diesel, gas, propane, and sometimes solar. Gas and propane-powered generators are ubiquitous, while diesel generators are rare. However, propane is becoming increasingly more popular than gas because it is more efficient and less expensive. 

Make sure to find out how much run time your generator has on a full tank. If it is not efficient, it will hurt your pockets as well as the environment. 

Top Brands

The following companies, listed in no particular order, consistently produce quality generators:

  • Honda 
  • Yamaha
  • Generac
  • WEN
  • Energizer
  • Champion
  • Predator


Depending on how much energy you will need and the brand, you can expect to find a portable generator for under $2000 and as low as $500. Built-in generators are more expensive and can cost anywhere from $3,000 to $15,000

Generally, if you want something to be long-lasting, you have to put the money into it. While there are less expensive generators out there, be wary of the quality and heartiness of it. Always take into consideration warranty as well as brand reputation. 


  • Store your generator correctly in a dry place as it can get damaged when exposed to the elements. Before putting it away, wipe it down and drain the fuel and lines. I would also suggest covering it.
  • Don’t forget to read the manual and service it regularly. Much like a car engine, you will need to oil your generator (even when you are not using it!) A well-lubricated generator also makes less noise, and that’s always a plus. 
  • Run it once in a while to make sure it is still functioning correctly. You will want to discover any issues before they become a problem. 
  • This may be obvious but never use old fuel. It can create build-up in the engine and decrease the performance of your generator.
  • Lastly, it doesn’t hurt to disconnect the batteries and store them separately, but it’s up to you.


Do you still have questions? If so, we may be able to address them with these FAQs.

What is wattage output?

Wattage is a measure of electrical power expressed in watts. The operating power of a lamp or other electrical appliances (including generators) is expressed in watts. When describing how much power a generator offers, people will use the terminology “wattage output.”

What does BTU stand for?

BTU stands for British Thermal Unit and is a form of measurement that measures energy. You will hear about it concerning heating and cooling units. All air conditioners come with a BTU rating, and it tells you how powerful it is. The higher the BTU rating, the more powerful.

How does an inverter generator work?

Inverter generators supply quiet, clean energy. It does this by converting AC power to DC power and then back to AC power once more. This ensures the power is “cleaned up” and has low THD (Total Harmonic Distortion). Your phone and laptop, and other sensitive electronics can only receive energy with low THD. 

What is a closed frame generator vs. an open frame generator?

There are two types of inverter generators: closed frame and open frame. 

Closed frames are compact and quiet. They have a protective shell that keeps all that noise sealed in. They are portable and usually only suitable for small loads. 

Open frames, on the other hand, have no protective shell and are this louder. They are usually capable of handling heavier loads, however.

How do I use solar power in my RV?

To satisfy your power needs through the sun’s rays, you will need to invest in RV solar panels. These will sit on top of your RV. The number of panels you’ll need will depend on how much power you need. 

Alongside your panels, you will need to have a solar charge controller. This takes the power the panels have created and sends it to your RV’s battery system to distribute it appropriately. 

I would look for a fully-loaded, pre-built RV solar panel kit, which comes with everything you need. It’s just easier and saves you the headache.

Keep in mind, solar power is a good, clean option but does not work on a large scale. This is because the sun is not up at all hours to power your electronics and the panels are only so big. You would need a massive bank of batteries to store the power created, and you would probably blow through it all just trying to run your fridge. 

What is the difference between starting watts and running watts?

Starting watts are what’s needed for the initial surge of power required for motor driven items like appliances and power tools. This is greater than the running watts the generator puts out. Starting watts only lasts for a few initial seconds.  

What is Carb Compliant and EPA?

CARB stands for California Air Resources Board, and EPA stands for Environmental Protection Agency. Both CARB and EPA are regulatory bodies tasked with addressing air pollution. 

CARB is generally stricter than EPA, so if your generator claims to be “CARB-compliant,” that means more than if it’s just “EPA compliant.”

Final Thoughts

With any of the reviewed products, you will get a quality generator for RV that will satisfy your power needs while RV camping. Of course, some are better than others, depending on your preferences, so hopefully, this guide has illuminated which one would be best for you.
