An air conditioner has become a necessity in our lives, but what about when you’re on a trip with your RV? In hot weather, a well-functioning air conditioner is essential to ensure that your vacation is comfortable. However, as an RV owner, you should be aware of how much power the air conditioner needs to function. This is where running RV ac on generator comes in handy.
Purchasing a generator might be difficult because it is quiet an investment. But getting a quality RV air conditioner will earn you the full benefits of that investment for a long time. On the other hand, a terrible one will completely sabotage that.
To save you the effort, we have filtered out the ten best generator for rv air conditioner out there that are worth your investment. Furthermore, we have considered everything starting from installation difficulty, fuel consumption, portability, etc that a day-to-day user would need to consider before buying one.
Nonetheless, might as well get started on the top 10 list without any further delay.
List of Best Generator for RV AC:
10 Best RV Generators For AC
Each of the generators mentioned below is suited for each individual. Moreover, some even might need the best generator for RV with 2 AC. That’s why we have kept the highlighted features tab so that you can easily find out the special characteristics that are ace in the hole for you.
1. Honda EU2200i
- Output Power: 2200 Watts
- Voltage: 120
- Noise level: 57 dBA
- Start Protocol: Recoil
- Gasoline Capacity: 3.6 liters
Honda already has a great reputation for generators so there’s no doubt that a Honda generator for LCD air conditioner would be a bad choice at all. The first thing to note in the Honda EU2200i is its portability. The generator is only 46.5 pounds which is certainly less when it comes to generators with such outputs, thanks to the GXR120 engine.
The GXR 120 engine is famous for its durability and efficiency. No wonder why this one has managed to be on the list. Moreover, there’s a handle on the top to help you carry it easily.
What’s more interesting to note is the easy installation system. It’s very simple and quick, just open the body with a screwdriver and pour some juice, and screw it back on. That’s it, now connect the cables with your RV and get it started.
The capacity of the gasoline is 3.6 liters which is a lot when you put together the Eco-Throttle system. Mingling the two manages to give you a run time of about 6 hours with your air conditioner. That means you can sleep at night peacefully knowing that the ac won’t get turned off due to low fuel because you got the top honda generator for RV air conditioner.
Besides that great efficiency, there’s also the “no more fuel” feature available. The smart system automatically turns off the fuel supply to the engine when the system finds the fuel bottomless.
Let’s come to the neighbor complaining section now. Will this Honda generator make noises that will force neighbors to call 911? The answer is certainly no. With the generator producing only 62 dB at max, there’s no way they will have the chance to do so. If you are wondering what 57 dB is like, it’s like hearing a conversation in a restaurant.
Now let’s take a look at its usability. The EU2200i has the simplest interface ever where everything is coded with colors so that you can easily understand what’s going on.
The only downside here is the engine starting protocol. It has a recoil engine where you have to pull the string several times to get the engine started which is not modern at all.
However, as compensation, Honda has added the three years warranty so that you can be carefree with their portable inverter generators.
2. Champion Power 200988
- Output power: 3000 Watts
- Start Protocol: Electric
- Voltage: 120
- Weight: 97 Pounds
- Fuel Type: Gasoline, LPG
The first thing you will notice is its look. The black and yellow color combination will surely make your brain release some of the dopamine at the first glance. Not just its look but the build quality is surprisingly hard-wearing as well. The starting wattage for the generator is 4500W which drops to 3150W after it has started.
The 3150W is a big plus point for an RV generator to run AC effortlessly as well as charge phones and laptops simultaneously. Moreover, the full tank is freaking 2.3 gallons with the dual fuel option which means it can store sufficient fuel to run for about 10 hours without the Economy Mode activated. With the Economy feature, you can go more as it is a great fuel saver.
The Champion Power generator is ideal for you if you don’t want to open your generator with a screwdriver every time you need to fuel it. It’s also as simple as opening the cap and topping it up with the easiest installation ever. So, no more disassembling for you.
To make things easier the Champions have provided their generators with an electric start protocol. You don’t have to pull the string to start the engine but only flip a switch and you are good to go.
Nevertheless, all these privileges come with a price and that is its weight. The Champion power is a 97-pound device that is considered moderate weight in the generator world.
However, if you are looking to keep things hushed as well as use the quiet generator for RV AC then it’s the ideal choice. The first thing is it only makes noise worth 61dBA and secondly the Champion Power generator allows parallel connecting. The parallel connecting option enables you to connect not one but two similar Champion Power generators.
2 AC units in your RV or even a caravan air conditioner is not a problem for it. Connecting the two generators outputs double power to fulfill your electrical needs as well as ensure the reliability of the power system. However, there would be more wiring involved in the process but it’s definitely worth it.
As a bonus, there are three years of warranty and lifetime technical support with the Champion Power generators. The technical support can come in really handy as most of us don’t like to deal with the insides of a generator. The team will help you to solve all your problems without you even doing anything.
3. Generac iQ3500
- Voltage: 120
- Weight: 109.1 Pounds
- Output Power: 3500 Watts
- Noise Level: 5dBA
- Start Protocol: Electric
Have you ever heard of a leaf falling? That sound is classified as 10dBA noise. Interestingly, the Generac iQ3500 generators sound of only 5dBA which can be considered inaudible. None of us like that generator sound when we are on vacation with our family and just trying to use the air conditioner for some chills.
Let’s dig into durability next. The Generac generators have casings made out of steel which is a really good sign of being durable. Besides that, the steel is even stainless so you don’t have to worry about it getting rusty and all.
Imagine you are in a park with your family in an RV but also a phone with a low battery! You don’t want to miss the small picnic with your family as well as don’t want to be there with an empty phone battery. What if I tell you that you don’t need to hop in the RV and stay there to charge your phone and also use your phone.
The Generac iQ3500 generator comes with USB ports that can be connected with your phone cable and start charging straight away. As it’s a generator, don’t worry about fast charging, it’s made for it. The fun fact is that as the generator is inaudible, you won’t even get badly buzzed while using your phone. You will definitely get the feel of the home.
Another reason this is the best RV generator for AC on our top list is for its digital LCD display. The smart display answers everything you need to know on a single screen. Starting from how much fuel is left, how long can the generator stay on with that much fuel, how long has it been running, how hot is your generator getting, etc questions that are worth knowing.
An air conditioner is a sensitive electrical device. For an air conditioner, the power that is not constant and may offer extra or little power is extremely harmful. We’re very sure you’ve heard of these incidents at least once. With Generac generators, you won’t have to worry about it. The generators are equipped with inverted technologies that ensure that every appliance receives consistent current as the power generated is cleaner and safer.
However, we should forget about that 109.1 Pounds of weight that we came across in the features tab. Honestly, it’s a bit heavy to lift with one hand compared to the other generators. Another thing to note is the hand bar is located in the side instead of the middle which is not a suitable place to put the handle on.
Jumping to installation difficulty, you would need to read the manual to install it properly unlike some easy installation generators. We also didn’t come across any warranty that is provided by most generator brands.
4. Westinghouse iGen4500
- Output: 4500 Watts
- Capacity: 3.4 Gallons
- Noise Level: 52 dBA
- Start Protocol: Push Button & Remote Electric Start
- Weight: 104.7 Pounds
A remote electric start has always been a fantasy for a generator. We have always seen cars that unlock with remote but who knew that day has come that generators now start with remote. The remote allows you to start or stop your generator from 260 feet away and that’s amazing.
You can be sipping a drink on your RV while turning on your air conditioner with a simple click from inside by powering on the generator. Technology never fails to make us lazier than we already are.
Customer satisfaction has been ensured by Westinghouse by offering the best service after purchasing their products. All Westinghouse generators come with a three-year guarantee, as well as labor service and parts coverage. Imagine not having to take a single headache for the next three years!
Diving into its size and durability, the iGen4500 has a generator size for RV air conditioner that is not so convenient. Also, keep in mind that it’s about 104.7 pounds and has a side handlebar which is not worth the effort just to use for the AC.
However, as compensation, there are wheels at the bottom and the handlebar is telescoping which certainly is a solution to it being morbidly obese. The wheels and telescoping handle turn your generator into a piece of luggage that can be transported anywhere.
At the start the power peaks to 4500 Watts which then jumps to 3700 Watts but still enough to run everything on your RV unless you are thinking of running a freezer with it.
Furthermore, the efficiency of this system is astounding. The iGen4500 manages to provide you with an 18-hour run time with a 3.4-gallon gasoline tank. What puts its name at the top of the efficiency list is its runtime and power-saving technology, which only produces the electricity needed to keep your electronics running properly.
Apart from all that, Westinghouse deserves credit for the digital display. The real-time digital display displays all of the vital information that a user requires to perform. With this real-time display, there will be no delays.
However, the installation process can get tricky. You need to open up the outer body to pour juice inside the engine, unlike other convenient generators where you can do it from outside.
5. WEN GN6000
- Voltage: 240
- Output: 6000 Watts
- Weight: 129.7 pounds
- Start Protocol: Electric
- Capacity: 3.4 Gallons
Now what brings the WEN GN6000 to the list of the best generator for RV air conditioners is its high voltage privilege. This is one of the few generators that have a voltage of 240 with a flipping switch to get back to the usual 120 volts. Air conditioners are known for their power consumption and more power means more fuel.
The 240 voltage can be turned on from the system board with just a simple switch that can save you a ton. High voltage reduces power transmission which means less power wastage and more fuel.
The GN6000 isn’t just stylish but durable as well. High-quality stainless steel is used in both the body and fuel tank of the generator. The two big wheels attached at the back make it more convenient for a user to move around with it. The big wheels give better control when pulling it sideways.
However, the generator looks very big in size as well as its weight which can be counted as a major drawback. Despite that, the fuel tank is vulnerable to the open which is not a good sign. You may have to be a bit careful using it out in the open as tanks are not so safe out there.
If you want to think positive then you no longer have to open up the casing to pour gasoline on it as it has the easiest pouring system.
Nevertheless, don’t forget the 6000 Watts power output that the GN6000 can provide. Yes, it’s named after its high wattage. The 6000 Watt generator is a handy feature that might save you a lot of trouble if you have lots of electronic devices to fuel simultaneously.
The 3.4 gallons of gasoline storage is another buying trigger. By providing the 6000 Watt output it can still hold up for 6-7 hours straight. It’s a good runtime if you think about 240 volts and 6000 watts. This one can surely be called a beast.
Bitterly there is no fuel-saving mode in the WEN GN6000 generator. It would have been great just to have an Eco Mode that could save some fuel in emergency times. Well, guess beasts don’t like to have the option. However, there’s always the 2-year warranty if your generator faces any trouble, it will be fixed by technicians nationwide.
6. Westinghouse WGen9500DF
- Engine type: 4 strokes
- Weight: 211 Pounds
- Start Protocol: Remote Control
- Dual Fuel
- Fuel Capacity: 6.6 Gallon
What’s noteworthy is how user-friendly the WGen9500DF is. It’s very remarkable for a generator, from the remote start to the dual fuel. It’s not a problem if you’re 260 feet away from your generator because you can start it with a single tap.
Moreover, the dual-fuel option allows the generator to run RV AC on both gasoline and propane. Having two alternatives for filling your tanks is quite handy. When it comes to output, though, propane isn’t as efficient as gasoline.
The gasoline can provide you with 9500 Running Watts whereas propane can only take you to 8500 Running Watts. Nevertheless, the power output on this power generator is truly mind-blowing.
The generator’s peak wattage potentially reaches 12500 with gasoline. Imagine what you could fulfill with such energy. Do you want to watch some television? Go ahead and do it! You’re hungry, but the food isn’t ready yet? Go ahead and activate the micro-oven!
Do you have a warm fuzzy feeling? Turn on the air conditioner and everything else that you need and the generator has more Watts ready for you.
Despite its powerful 457cc Westinghouse engine, the engine also functions with an automatic cooling system. When the load starts to get big, the engine usually starts to heat up as well but not with this one. Even if you turn on everything in your RV, the cooling system copes with it to keep the engine as cool as possible.
Many generators feature a digital display that indicates the output power, frequency, and other information, but what makes this one unique is its honesty. The display will show you everything that a standard generator display does, but with the addition of the generator’s lifetime hours.
As a result, you can now see how many thousands of hours the engine has remaining to keep operating smoothly.
However, before purchasing it, we should evaluate its weight and installation process. The WGen9500DF weighs around 211 pounds and is not a one-hander. However, these types of heavy output generators are normally this heavy and are appropriate.
When it comes to the installation process, installing a generator has never been easier. The job can be done with a simple wire connection to your RV. It’s more than likely a plug-and-play system!
7. Pulsar G12KBN
- Output: 12,000 Watts
- Dual Fuel
- Engine Type: 4 stroke
- Fuel Capacity: 8 gallon
- Weight: 209 pounds
- Start Protocol: Electric
There is no better alternative than a G12KBN if you need a long-term backup for your air conditioner. Even with heavy power electrical gadgets, the generator’s 8-gallon fuel capacity offers a minimum of 12 hours of running. If the maximum output is not used, more hours of performance can easily be expected.
Nonetheless, fuel is expensive, and filling the 8-gallon tank isn’t worth it if the generator doesn’t have a fuel-saving mode. And guess what? The G12KBN is built in such a way that it preserves every last drop of your fuel. No, there isn’t a separate fuel-saving mode that you may use at any time, but the entire device is fuel-efficient.
Moreover, when in service, the generator produces roughly 70 to 80 dAB, which is quite high and sounds like a vacuum cleaner. It should not be a problem if you are not concerned about noise and plan to park your RV and keep the generator outside of it.
When using gasoline instead of LPG, the device’s starting power is 12000 Watts and it runs at 9,500. We won’t bore you with the benefits of such high wattage because you already know them. You should also be aware of the advantages of using gasoline rather than LPG gas. As a result, it also produces more watts.
Installing your RV with it, on the other hand, is as straightforward as cutting a cake. The power source is a certified RV-ready generator which means best compatible with your RV.
We haven’t tried it yet, but it has received positive feedback for its durability. The G12KBN, which is made of robust Chromium steel, is at the top of the list of long-lasting generators. Furthermore, don’t forget about the 1-year warranty if you find it to be insufficiently durable or has other issues.
8. DuroMax XP13000EH
- Output: 13,000 Watts
- Engine Type: 4 stroke
- Weight: 234 Pounds
- Dual Fuel
- Start Protocol: Electric
If you care about the environment and want your RV’s air conditioner to function as seamlessly as possible, the DuroMax generator is the right choice for you. It has been approved by the EPA (Environmental Protection Agency), and it is one of only a few that have been approved thus far when it comes to generators.
In comparison to other generators, this one has quite a decent efficiency. The tank has a capacity of 8.3 gallons and may be filled with propane or gasoline, perks of having a dual-fuel engine. However, Gasoline, on the other hand, has a longer runtime than propane. The DuroMax can supply up to 8 hours of emergency backup on average.
Talking about efficiency and environment friendly, the emergency backup guy also comes with a low oil shutdown feature. When the generator detects that it has run out of oil and that it is no longer safe to continue supplying power, it immediately shuts down for safety.
Let’s have a look at portability right now. Duro Max generators feature a pair of legs that allow them to move wherever you want them to. Even though it weighs 234 pounds, the control on this monster is excellent.
It has managed to ensure good grip and steering with those enormous tires. This one might not be the smallest generator to run RV air conditioner but it is a portable one.
For some people, the lack of a recoil start is a welcome relief. If you’re one of them, the DuroMax ones are available all the time. With an electric start, the engine starts instantaneously with simply a switch, saving you the trouble of repeatedly pulling those strings.
This product has a noise level of around 70dBA or below. With that 10500 watts running continuously for a longer amount of time, the noise level increases. Don’t worry, the highest volume it can achieve is 70dBA.
Despite all the good sides, there was no sign of warranty mentioned on these things. However, there have been reviews from the users that a warranty card has been provided in the box that their product came in.
9. Sportsman 4000W
- Weight: 90 Pounds
- Start Protocol: Recoil
- Output: 4,000 Watts
- Fuel Capacity: 3.6 Gallons
- Dual Fuel
Here it is if you are looking for a generator you are sure that you don’t need to run heavy electronic devices but it is also affordable. If you’re not planning on doing anything heavy-duty, such as operating a freezer, the Sportsman 4000W generator will be adequate. Don’t worry, the 4000W is sufficient enough to run your RV’s air conditioner just fine.
The minimalist generator is built like a Nokia feature phone and never fails. With premium stainless steel and 2.1 percent carbon, you can count on it to last. Furthermore, the combination of portability and durability is unmatched.
Its super lightweight of 90 pounds and high carbon construction makes it transportable to any location. There’s no way it’ll be damaged by any kind of hard impact. In addition, the handlebar in the center is always present to allow it to be carried with one hand.
The 3.6-gallon fuel tank can hold both gasoline and propane. Furthermore, the run-time on these items is a real game-changer. The Sportsman generator can run for up to 12 hours, which is incredibly long when compared to other generators. The main reason is that it produces less power than the other big generators.
Lastly, the generator produces only 69 decibels of sound, which is sufficient to keep it quiet. Although the recoil start mechanism is a drawback, there is a 2-year warranty to keep you pleased.
10. ONAN QD
- Output: 8000 Watts
- Fuel type: Diesel
- Weight: 420 pounds
- Start Protocol: Electric
- Noise level: 66 dBA
This is the most unique of them all. It can be startling to find a CPU-like generator to operate your RV instead of Google Chrome. However, unlike a CPU, installing this machine is not a tough task. Everything is ready for you; all you need to do now is hook it up to your RV.
Surprisingly, the CPU-like generator has a chipset, but it is neither from Intel nor AMD. The chipset handles everything for you, so you don’t have to. From adapting its engine to meet demand and supply to avoid wasting fuel to lowering its noise level as much as possible. Moreover, it also includes self-diagnostic abilities for resolving its issues.
Another feature that distinguishes it is its capacity to run on diesel. Diesel is far superior to any other gas on the market in terms of cost savings. It produces the same amount of energy using less fuel.
Despite its efforts to create the ultimate generator, it weighs 420 pounds, which is extremely heavy even in the generator market. It would be a must-buy perfect generator if it had all of these capabilities while also being lightweight, yet this weight is a big minus.
After considering its liquid cooling system and a three-year warranty, the ONAN QD isn’t perfect, but it’s also not the worst. You can go for it if you’re a feature-based person who doesn’t have a problem with weights.
Generator for RV Air Conditioner – Buying Guide
It hasn’t always been easy to find the right product for you. When it comes to finding your suitable generator, there are a lot of things to keep an eye out for.
Each generator is designed for a specific group of people, yet the majority of people are tricked after purchasing one. This is because most of us aren’t familiar with generators, and they’re certainly not a common purchase like a t-shirt.
You don’t have to worry about it anymore because we’ve compiled a list of all the crucial features to look for in a generator to power your RV’s air conditioner. It will assist you in making the best decision possible by removing all of your doubts and allowing you to make an informed purchase decision.
We’ve gone through everything in depth, including what wattage is adequate to power your air conditioner and what capacity is required for a long runtime on your generator.
Let’s get this guide started.
No one buys a generator only to run an air conditioner. Many electronic devices need to be used like charging your phone and all. So choosing the ideal output power is essential when it comes to generators.
It’s always a good idea to buy a few extra output power generators than you think you’ll need because you never know when you’ll need that extra 100 watts. Here, 4500 Watts is a safe bet. Any generator with this much power can handle heavy-duty tasks while being efficient.
This one is a difficult one. Ask yourself, are you that much lazy to even go up and start the engine with pullings strings? If yes then definitely go for the remote-controlled ones.
However, don’t forget that there’s a range for using your remote and usually it’s about 60 feet or so. Always check out for the range as a shorter range might be insufficient to fulfill your laziness.
There is always an alternative recoil start system for every remote-controlled generator. It’s because those strings are more reliable than remote control waves.
Generators aren’t cheap and are a definite investment. Having a reliable and durable generator is what every user wants and won’t hesitate to put their money on. However, you can’t just check its durability within the return period.
One approach to judge a thing’s durability is to look at the material it’s made of. Go for it if the stainless steel has a carbon percentage of more than 1.8 percent. Also, check to see if the manufacturer offers a warranty. The longest warranty offered by a generator is three years, and it is recommended not to choose one that has not been warrantied at all.
Number of ports
Having a count of the ports is something to keep an eye on. You don’t need a generator for your RV if it only has one or two outlets. As I previously stated, you are most likely not purchasing the generator only to run the air conditioner. The number of ports is just as crucial as the number of watts.
In most cases, 4 to 5 ports are sufficient to meet your everyday requirements. However, you are the best judge of how many ports you require.
Every day, as modern technology advances, Most generators that produce loud noises are becoming extinct. Let’s face it, no one likes the clinging noises that old generators used to make, but thanks to improved technology, such noises have been reduced.
If you’re searching for numbers, though, a generator with a noise level of 60dBA or less is virtually silent and nearly unnoticeable. Anything above 100 dBA isn’t worth it because you’ll remember your vacation exclusively for the noises of the generator.
The efficiency of a generator has become the most significant feature. You might have a large fuel tank with a lot of gas, but it’s worth a lot less than a regular fuel tank if you don’t have a decent efficient system.
Every day, most generators arrive with a slew of new features to help you save money on gas. So looking for a generator with a fuel-saving mode is a wise decision. However, the type of fuel used is also important. Diesel is by far the most efficient.
It’s also a good idea to look for an inverter generator for RV AC. Inverters save fuel consumption by adjusting the engine speed to your demands.
What Size Generator to Run Camper AC?
The first thing to know is that the size of the generator doesn’t matter at all. As long as the generator has greater running watts than your Camper’s running Watts then you are more than good to go.
A starting Watt is the amount of power required to start an electronic device such as an air conditioner. It’s usually a higher number than running watts because practically every machine requires more power to start up.
Running watts, on the other hand, are always constant and, in most cases, far less than starting watts. We’ve seen generators with starting Watts that are half as high as running Watts.
When purchasing a generator, there are numerous aspects to consider, the most essential of which is the output power. If all you want to do is run an air conditioner in your camper, a 2000Watt generator would suffice.
Will a 3000-watt Generator Run an RV Air Conditioner?
Well, that depends entirely on the type of air conditioner you have in your RV. However, you can always calculate the Watts required to run your air conditioner and match the output power of your generator. It’s normally found in the box that comes with the air conditioner.
It’s always a good idea to get more watts than you think you’ll need only to power your air conditioner because you might need to connect other devices as well.
Despite this, some AC boxes do not have started running and beginning wattages on their bodies. If you can’t find them, look up BTU, which stands for British Thermal Unit. There’s an easy technique to figure out the power using the BTU value.
To keep it simple, one Watt equals 3.41 BTU. To calculate your starting and operating watts, simply divide the BTU figure by 3.41.
It goes without saying that most of us have a lot of questions about generators for running our RV’s air conditioning. Because this isn’t a regular purchase for most people, asking simple inquiries isn’t something to be ashamed of. We’ve answered a few questions that may assist you in making a purchase.
1. Can I run my RV air conditioner from a generator?
Yes, you can, and if you’re talking about safety, it’s a great alternative. However, you should always be cautious when selecting a generator and ensure that it has sufficient power output.
2. How To Calculate The Size Of Generator You Need?
To begin, figure out how much power output you’ll need in an RV to meet your needs. Sum up the running watts for all of the electrical items that are usually printed on their body. After that, purchase a generator with a few additional watts for greater outcomes.
3. How long will RV AC run on a generator?
Well, that depends entirely on the context. However, based on estimates, you can run the air conditioner for 6-8 hours on 2 gallons of gas. Furthermore, if it runs on diesel, it may run for longer periods while using less fuel.
4. How big of a generator do I need to run a 13500 BTU air conditioner?
A 2000 watt generator is sufficient to power your 13500 BTU air conditioner. However, it’s usually a good idea to acquire a little extra than you think you’ll need.
5. What size generator do I need to run a 15000 BTU RV air conditioner?
To run such high BTU-rated air conditioners, 4500-watt generators are required. You may want to look for a fuel efficiency mode so you may save money on gas with such high-wattage air conditioners.
6. How big of a generator do I need to run a 12000 BTU air conditioner?
The majority of generators on the market today are compact and powerful. Almost all of them weigh around 150 pounds or more.
This is all we had on the list for the best generator for RV air conditioners. It’s no longer a secret that you don’t need a gigantic generator to keep those cool breezes flowing. Before making any hasty decisions, we recommend reading the buying guide.
However, if we had to pick one from the list, it would be the Honda EU2200i. It’s one of the lightest and also most efficient generators we’ve confronted, with features that every user would appreciate in their daily lives.
Yet, you already know which generator would be best for you. Don’t worry about buying the wrong one because this is the finest list.
