Best Generators for RV Air Conditioner Buying Guide
Finding a generator to run RV AC units will require a handle of certain factors. Our buying guide will provide everything you need to know about these devices. You shouldn’t have any difficulty choosing a perfect option with it.
If you consider using an AC a high priority when traveling, it’s essential to find a generator with enough power to run it. An RV generator’s wattage will clue buyers into whether it can handle running their air conditioner.
Most RV owners will consider this factor as the most important when choosing their generator. After all, your RV AC wattage needs will be the most among all your appliances. It even outpaces other larger appliances like a refrigerator or electric heaters.
As a result, an RVer needs to know how many watts their AC uses when starting up and running. You’ll need to understand its running wattage will be lower than its start-up wattage. You should use the AC’s start-up wattage as a beginning point and find a generator that can handle it.
Portability and Size
As you might imagine, portable generators offer a convenience level other types can’t. People who decide to buy a portable generator will want one with handles and wheels. Most options will come with these features, but some lower-quality options don’t. Their inclusion will make moving the device much easier than you might expect.
But it’s also essential to consider their overall size when choosing the suitable model. You’ll want a compact, lightweight option that fits into your motorhome without much hassle.
Every generator has a limit on how much fuel it can hold. If you’re looking for a model that doesn’t need much refueling, look into each model’s fuel efficiency. It’s an essential aspect because the prices of diesel, gas, and propane are constantly changing.
As a result, you don’t want a generator that guzzles through its fuel. You want an option with a reputation for being fuel-efficient and cost-effective. I’d recommend looking at the customer reviews to understand the efficiency of each choice.
Generator noise is a common nuisance inside campgrounds. I can’t tell you the number of times a neighbor’s generator kept me up through the night. I’d imagine you don’t want to be the cause of another person’s sleepless night.
Therefore, a generator’s noise level should play a role in your final decision. It would be best to look to buy the quietest generator for RV usage to ensure it won’t be a nuisance. It’s another area where customer reviews will be a massive help.
Type of Fuel
As I mentioned earlier, the price and availability of fuels are always fluctuating. It’s why most RVers try to find generators with the ability to use different types of fuels. These options will feature a dual fuel option to offer the wanted versatility.
But some RV owners might want a single fuel generator. In any case, you’ll need to find a model that fits your particular fuel needs perfectly.
Our FAQ section will cover a few other essential topics to ensure you’re fully prepared. It’ll make sure you become an expert on everything about RV generators for AC units.
Who is this for?
RVers who want to run their AC unit without using shore power, such as boondockers or dry campers, will need a generator. But this generator will require enough wattage to run the unit effectively. It’ll then keep you cool during those summer afternoons without using a campground’s hookups.
As a result, an RV generator for air conditioner units becomes a necessity for these travelers. It might represent the only way to run these devices when traveling away from civilization.
What are the different types of generators for RV air conditioners?
A simple way of separating generators for RV AC units is by their start-up method: manual or electric. Most RVers are probably familiar with the manual types. These models are the ones with those pull cords, which can be a hassle for some users.
But I should mention that manual generators are easy to use when first buying them. However, cord wear/tear can make this process a lot more taxing over time. Some RVers don’t like the pulling process at all and avoid these models altogether.
Meanwhile, electric generators start with an RVer flipping on a switch or pressing a button. It’s a much more convenient and less annoying way to get these devices running. But electric options tend to be much more expensive because of this convenience.
Electric generators also tend to have internal battery malfunctions as they get older. Due to this, you could be left without any juice when your electronic start-up stops working.
These potential issues make following the correct maintenance processes essential. It’s a simple way to ensure an electric generator doesn’t have a short lifespan.
How do generators for RV AC work?
Understanding how an RV generator works isn’t overly complex. In the simplest terms, your generator works sort of like a bank with a specific amount of energy inside it. Every time you run an appliance using the generator, a portion of this energy is taken away.
It’s also essential to note that generators for RVs have two measurements: start-up wattage and running wattage. Your start-up wattage is the amount of energy that your generator can provide to get the AC started.
After running the AC for a period, some energy will return to your generator’s “bank.” The amount of required RV air conditioner watts to keep it working is the running wattage. Here’s a little example to provide a bit more context into this process.
Let’s say your generator can provide 4000 watts, and the needed RV air conditioner wattage for starting is 3800 watts while 1300 watts is required for running. Once the AC unit is running, this configuration would give you 2,700 watts to use for your other appliances onboard your motorhome.
Advantages and disadvantages of using generators for RV AC
A generator for travel trailer AC or RV AC units can provide rig owners with many benefits. Honestly, these devices are an excellent and valuable investment for any RVer. It’s an easy way to ensure your motorhome remains comfortable on those hot summer days.
For instance, those summer blackouts won’t be a sweat-inducing nightmare. These devices will instead ensure you can turn on the AC and other appliances onboard your motorhome. It can make an uncomfortable, scary situation a lot less complicated and frightening.
You can also expect these RV generators to be portable and storable. These benefits come from most models having lightweight, compact designs. Other standard features like wheels and handles are endlessly helpful in these areas.
Durability is another area where these devices tend to excel. High-quality options will consist of heavy-duty materials made for dealing with the RV life. You should expect them to be onboard your motorhome for a long time.
But RV generators for AC units are an expensive investment with a habit of producing lots of noise. Due to this, buyers must do extensive research on each option to ensure they know what it provides.
Who makes the best generators for RV AC?
Finding trusted brands is a little tricky in this crowded marketplace. Thankfully, I’ve provided a few high-quality examples in our product review section. Buyers who stick with those brands should expect a successful buying experience.
I’d also recommend buying a Honda generator for RV air conditioner units. Honda is another brand that has an excellent reputation among the RVing community.
What size generator do I need to run my RV AC?
As you might imagine, RV air conditioners require a lot of energy to start and keep running. An average RV AC will need a generator with at least a 3000 to 5000-watt starting capacity. If you’re wondering what size generator for RV with 2 AC units, anything with over a 5000-watt starting capacity should do the trick.
How long can you run an RV air conditioner?
If you’re connected to shore power, an RV air conditioner can run continuously. But a generator will have limits based on its specific fuel and how many watts to run RV AC unit. In any case, you should get a good run of cool air with almost any capable RV generator.
Any care and maintenance tips?
Each generator will come with an extensive manual, which is a vital resource. This manual provides everything an RVer will need to know about care and maintenance procedures. If you stick to them, your RV generator should remain usable for a long time.
The best generator for RV air conditioner units should now be within your grasp. It’s just a simple matter of trusting what you’ve learned and using it during the search. From there, the right choice will become clear.
