Will a Honda 2000 Generator Run an RV Air Conditioner? (Explained)

Will a Honda EU2000 Generator Run an RV Air Conditioner

Have you ever wondered if a Honda 2000 generator will run an RV air conditioner?

The whole point of an RV is to be able to take the comforts of home with you wherever you want to go. Part of that means having a reliable source of air conditioning that will effectively keep your RV cool during hot summer nights.

It’s never a pleasant feeling when you go to bed and wake up feeling sweaty and sticky.

However, as you may already know, the main air conditioning units in most RVs can’t be powered by the RV’s battery or even its engine alone; they usually require an external power source in order to work.

In most cases, a gas generator is needed to provide an RV’s air conditioning systems with sufficient power.

So, will a Honda 2000 generator run an RV air conditioner? No, a single Honda EU2000 generator isn’t sufficient to power anything but the smallest of A/C units. The 1,600 running watts that the EU2000 produces are just barely enough to keep an 8,000 BTU A/C unit running.

However if you can hook up two EU2000s generator together to produce double the wattage, it’s likely that it would be enough to power a small- to medium-sized A/C unit with ease.

There are tons of different gas generators out there that are suitable for this purpose, but today we’ll be checking out the Honda EU2000 generator. The EU2000 is renowned for being reliable, fuel-efficient, and capable of operating a wide range of appliances, including RV air conditioning systems.

We’ll be taking a look at the capabilities of the Honda EU2000 generator in this article, and we’ll also provide you with a buyer’s guide to help you pick the best generator for your RV’s air conditioning needs.

Overview of the Honda EU2000 Generator

๐Ÿ‘‰ The Honda EU2000 is incredibly popular as a portable generator among people who regularly use them.

While the EU2000 was discontinued in 2018 with the introduction of Honda’s new generator, the EU2200, the EU2000 is still commonly used by many and used EU2000s can be easily found on the used market.

๐Ÿ‘‰ The EU2000 is an inverter generator, which differs from a construction-style portable gas generator in several ways. Inverter generators are typically more expensive than construction generators, owing to their more complicated engine design.

However, inverter generators offer several distinct advantages over other types of generators; for one, inverter generators can automatically adjust their throttle depending on the power demand of any appliances they are hooked up to.

This is in contrast to construction generators, which constantly run at full power and are therefore much less fuel-efficient.

๐Ÿ‘‰ Because inverter generators aren’t running at full throttle all the time, they are also less noisy than construction generators.

Inverter generators usually have more advanced exhaust systems than construction generators, which further reduces an inverter generator’s noise level.

Additionally, because inverter generators are designed to regulate their own throttle depending on how much power is being drawn from them, this also makes them much more fuel-efficient than construction generators, and they produce fewer emissions overall.

๐Ÿ‘‰ The EU2000 has several other features that help it stand out as a top-notch inverter generator. It can be run in parallel with another EU2000 generator, giving you twice the power of a single generator.

It also weighs in at just 46 pounds, making it very portable compared to a lot of other generators.

It also includes features such as AC and DC outlets for charging various devices, an “Oil Alert” system that will automatically shut the generator off if its oil supply gets too low, and the ability to run for nearly 3.5 hours at full load.

On top of this, the EU2000 is EPA, CARB, and CSA-approved, so you can run it basically anywhere outdoors.

RV Generator Buyer’s Guide

If you’re buying any generator to use with your RV, it’s important to know beforehand what the right one for your needs is.

Ideally, you want to pick a generator that is powerful enough for all of your appliances, but also light and small enough to easily transport and quiet enough so you can operate it whenever you want without disturbing those around you.

In this section, we’ll go over everything you should know about buying a generator for an RV and using it with an A/C unit.

Do I Need a Portable Generator At All?

In all fairness, you don’t ALWAYS need to bring a generator along with you if you’re taking your RV somewhere. If you just plan on taking your RV to dedicated campsites, chances are you’ll have onsite power available to you.

Additionally, a lot of modern RVs come with built-in generators that can provide power to your various appliances.

However, not every campsite has access to an outside power source, especially if you’re camping somewhere way off the beaten track.

Moreover, depending on how many appliances are in your RV, your RV’s onboard generator might not be able to provide enough power for everything.

In any case, while it’s not mandatory to bring along a portable generator if you’re taking your RV out for an excursion, it’s never a bad idea to do so anyway.

Most modern generators like the EU2000 are compact, quiet, and can provide a great source of backup power should you ever need one.

 What’s the Best A/C Unit for an RV?

When buying an A/C unit for your RV, obviously you want to get one that can adequately cool the entire inside of your RV. You wouldn’t want to buy an A/C unit and install it only to find that it barely functions as intended.

You’ll want to select an A/C unit with a BTU rating high enough for the interior space of your RV. Here’s approximately how this breaks down in terms of the square footage of your RV versus the BTUs necessary to keep it cool:

  • 200 sq. ft. = 8,000 BTUs
  • 300 sq. ft. = 10,000 BTUs
  • 400 sq. ft. = 12,000 BTUs
  • 600 sq. ft. = 14,000 BTUs

Therefore, the best A/C unit for your RV really depends on how much interior space you need to keep cool.

If you have a smaller RV or trailer, you can get away with using a less powerful A/C unit, but if you have a larger RV then you’ll struggle to keep your interior cool without a suitably powerful A/C unit.

How Powerful of a Generator Do I Need for My RV?

You can’t just hook up any old generator to your RV’s A/C unit and expect it to get the job done. If your generator isn’t powerful enough, then any appliances connected to it will overload your generator and cause it to shut off.

More powerful A/C units require more watts to run, as you might expect. Here’s approximately how many watts you’ll need to power an air conditioner based on how many BTUs it puts out:

  • 8,000 BTUs = 1,400-2,100 running watts
  • 10,000 BTUs = 2,200-2,600 running watts
  • 12,000 BTUs = 2,600-2,900 running watts
  • 14,000 BTUs = 3,000-3,200 running watts

Considering that you can hook up two EU2000s together to produce double the wattage, it’s likely that two EU2000s would be enough to power a small- to medium-sized A/C unit with ease, and perhaps even enough to power a large A/C unit in a pinch.

Keep in mind, though, that you’ll most likely have several other appliances in your RV that require power, such as a fridge, a microwave, a TV, and a DVD player or satellite receiver.

If you’re using a plugged-in laptop or a portable fan, these will also drain some of your available watts.

When selecting a generator for your RV, make a list of all the appliances in your RV and the starting watts required to operate them.

Add up the starting watts necessary for each of your appliances. Whatever the total is, you should look for a generator that can handle this number of starting watts. 


If you own an RV and you plan on getting the most use out of it possible, you’re going to need some kind of generator on board.

Whether it’s a built-in RV generator or a portable, multi-purpose generator, having a generator on hand is some good insurance for if you need to power your appliances when your RV is not running.

In terms of portable generators, the Honda EU2000 is one of the best for RVs. It’s small, efficient, and quiet, and while it might not be powerful enough on its own to run all the appliances you want, you can easily run it in parallel with another EU2000 to double your power output.

On top of this, since the EU2000 is now a slightly older model that is now out of production, you can probably find some great deals for these generators on the used market.

All in all, if you’re looking for a reliable source of external power for your RV’s A/C system, you can’t go wrong with the Honda EU2000.
