What Is an RV Generator?

An RV generator is a type of generator that is used in campers, travel trailers, 5th wheels, motorhomes, and any other type of recreational vehicle. It supplies power to all the electronics and appliances that are onboard the RV. It can make your life on the road a lot more comfortable since it gives you the freedom from the dependability on the campsites’ power source. And what makes an RV generator different from a standard generator is the addition of a TT-30R receptacle and the more lightweight and compact design.

How Does an RV Generator Work?

RV generators work the same way as standard ones do. Typically, it will consist of an engine, fuel source, alternator, starter, and outlets. These are the basic components. There can also be other parts that will differ from model to model.

A generator also needs something to draw power from. For this purpose, they use either liquid propane or gas.

The engine, which runs on fuel, provides electricity to the generator head by spinning a shaft. A typical generator is also equipped with a constant speed regulator that maintains the optimal speed of the spinning shaft in order to provide the required amount of mechanical energy. Next, the generator moves a magnet near a wire, which produces the electron flow. And finally, this harnessed flow of electrons is redirected to outlets, supplying electricity to your appliances.

Portable RV generators are measured in watts, which shows the amount of power they can produce. There are also two types of watts: starting watts and running watts. The former is the extra power that is required to effectively kick-start larger motor-driven appliances or to start multiple items at once. And after an appliance has been started up, it usually settles down to a lower wattage and that is the continuous running wattage.

What to Look for When Searching for the Best RV Generator?

Now that you know the top available options, how to know which is the best generator for your RV? Everyone has their own needs and requirements, so a certain generator can be ideal for one person but useless for another. That’s why it’s important to understand the factors that you need to consider before choosing the right RV generator that would be optimal for your specific situation.

Inverter Generator vs Conventional Generator for RV

One of the first things you should consider before choosing a certain RV generator model is the type of generator you’d prefer. Do you want just a conventional generator or an inverter generator? There are pros and cons for both types and determining which one would be best for you depends on what it will be used for.

One of the differences between the two is in the type of electricity they produce. Conventional generators produce only AC power and inverter generators produce power in 3 phases. Inverter generators output AC power like conventional generators but then they convert it to DC and then they invert the current back to clean AC.

The produced clean AC current is what makes inverter generators so unique. The created electric current has minimal harmonic distortion, which makes it a safe energy source for sensitive electronics.

So, if you’ll be powering any devices that use some form of a microprocessor, you will benefit from the cleaner power provided by an inverter generator. And that doesn’t include just your computer. Many different devices and appliances today use sophisticated electronic circuitry, so it can include phones, TV, game consoles, and even kitchen appliances. All of these are very sensitive to the quality of electricity and powering them with a traditional generator can damage them or cause them to malfunction.

Traditional generators, on the other hand, have a much messier sine wave. The output is directly connected to the load, without any regulating of the power. It’s still a suitable power source for most appliances but it can be damaging to sensitive devices.

Inverter generators also have the advantage of better fuel efficiency due to how they operate. Unlike a conventional unit, they automatically adjust the engine speed according to the load. This means that they require less fuel to provide similar run times.

Moreover, inverter generators are more compact and portable. They are also quieter and many manufacturers offer to make up for the low output by offering parallel connection of two inverter generators together.

As for the advantages of conventional generators, they include a higher power output and lower price. So, if you don’t plan on powering sensitive electronics, you need maximum power, and you have a lower budget, you might prefer a conventional generator.

Fuel Type

You might also want to consider the fuel type that will be used by the generator. You can pick one that is easier for you to get access to, which will help to make your life a bit more effortless. However, in some cases you don’t have to choose between the two main types, which makes it convenient for when you’re traveling far from home and you’re not sure what fuel will be available.

  • Gas is the most common type of fuel used for RV generators. It’s relatively cheaper compared to other types and more readily available.
  • Propane is another common type. They are popular due to the indefinite shelf like and quieter operation. Moreover, they offer longer run time on a single tank than either gas or diesel does. If you choose the propane option, make sure that you’re using a propane regulator on your propane tank.
  • Diesel portable generators have better fuel efficiency. This means that you get more power out of a single tank. However, this type of portable generator is rare and they are quite noisy and smelly, which wouldn’t be ideal for RV use.

As we’ve mentioned, you can also get a dual fuel generator. It will offer dual fuel capacity, so you can choose the more convenient fuel depending on the situation.

Power Requirements

Perhaps the biggest consideration for selecting the right RV generator is the power output of the unit. All generators are not made equal and different models offer a specific power output. And this amount of power is measured in watts.

You need to pick a model that would be able to meet the power requirements of your RV appliances. If all you need is to power some lights and mobile phones, you can get a small, low wattage generator. But if you need to power an AC, fridge, microwave, and more, you will need a more powerful unit.

For example, 13,500 BTU air conditioner unit requires 2000 watts, microwaves use about 1000 watts, a fridge runs on about 180 watts. In all, just check the wattage of the appliances that you use in your RV. Add the light’s power requirements and the total will tell you the amount of power that you need for your recreational vehicle.

In most cases, the more power, the better. However, at the same time, don’t overspend on an oversized unit that would produce way more power than you use.


You should also look at the construction of RV generators. Review the overall build to see how this piece of equipment would be able to withstand the test of time. It should have a sturdy design that is made using high quality materials.

Fuel Efficiency

Fuel efficiency is also an essential factor that you should look out for. Better fuel efficiency will not only help you to save money on fuel costs but will also be better for the environment. Brands use different technologies to make their generators more efficient. And some technologies are better than others.

For example, inverter generators are considered to be the most fuel efficient portable generators, providing longer operation times on a single fuel tank. Unlike traditional generators, instead of engaging the engine in full-throttle mode all the time, they adjust the speed according to the load. So, if you need to power just some light appliances, the engine speed would automatically be slowed down and at the same time, this will reduce fuel consumption. Moreover, look for generators with an Eco mode, which also provides better fuel efficiency.

When looking into fuel consumption, check also the estimated run time of the generator on a single tank of fuel. Generators can run anything between 4 and 18 hours before you’ll need to refill the fuel tank. With longer run time, you will have less hassle of having to constantly add fuel to the generator.

However, of course, higher loads will also mean faster depletion of fuel. And longer run times are usually offered by units that are bulkier and that come with larger sized fuel tanks. Here you need to decide what is more important to you. Would you prefer a smaller sized generator or one that would be able to run for a longer time without requiring any maintenance?

Quiet Operation

Since you’ll be using the chosen portable generator on your RV where you’d rather be enjoying the quietness and tranquility of nature, look for units with a lower noise output. Especially if you’ll be spending many nights sleeping in your RV, you want the generator to be as quiet as possible.

Moreover, most national parks and campgrounds have noise limitations. Typically, it’s up to 60 decibels at a 50-feet distance. And if you’re parked at a campsite, you don’t want to annoy your neighbors with the thumping sounds of your generator. So, keep that in mind when choosing the ideal RV generator.

It’s worth mentioning also that the bigger the generator, the more noise it will produce. And if you want the quietest generator, consider getting one of the inverter generators. They usually produce a noise level of only about 50 to 60 decibels, which is similar to the noise level of a normal conversation.

Portability Features

Most RV owners prefer to buy a portable generator since it adds versatility to the unit. Aside from using it to power your travel trailer essentials, it can also be used to provide electricity for tailgating or during power outages.

Look for an RV generator that will be easy to carry and move around. Many manufacturers today equip their generators with wheels and carry handles. Lots of the units also feature a convenient framework, which allows for easier gripping and carrying. An optimal choice would also be a generator that is not too heavy, so it could easily be transported by just one person.

You can also opt for a permanent unit that is installed directly into an RV and that is tied into an onboard fuel source. These usually cost a bit more and they won’t be able to offer any other use except for powering your RV.

Available Outlets

One more thing to consider when choosing a portable generator is the available outlets on the unit. It should have all the necessary outlets, so you would be able to easily plug in all your RV appliances and have them ready for use. For example, if you’ll need to power some 12V appliances but the generator offers only 120V outlets, you will need to additionally purchase an adapter.

Most generators offer 120V household outlets. Other included outlets can also include USB ports, twist locks, RV outlets, and DC outlets. Consider which of these you would actually need and look for a unit that would be able to meet these requirements.

Protection Features

A good RV generator should also have proper protection. The stand protection should include low-oil shutdown and circuit protection. There should also be GFCI protected outlets and a surge protector against overloads.

Other User-Friendly Features

An ideal generator will also offer different user-friendly features that will make operating it easier. One of such features can be an LCD display, where you would be able to view different information about the unit’s operation. Typically, it would include load, run time, and frequency. Other features that would make your generator use easier and more convenient include a wireless remote start, a fuel gauge, and a voltmeter.


When shopping for anything, you probably have a certain amount of money that you’re ready to spend. So, before you start shopping around for a new RV generator, decide on that limit and set your budget. It will help you narrow down the options and choose a more suitable unit for your requirements. Also, spend some time comparing the prices of products within your budget to see if their prices correspond to the features and quality they offer. Try to find a unit that would offer you the best value for the money.


RV generators are a big investment, so it’s important to make sure that it will last a long time. And a long warranty is a good sign of a high quality product. It shows that the manufacturer is confident in the quality and reliability of their products.

All electric appliances are prone to various defects and issues. It’s also true for RV generators. And if you do get a malfunctioning unit, you want to be sure that the manufacturer will fix this issue. That’s why it’s important that the products come with a good warranty. A good warranty for RV generators is 3 years and if a manufacturer offers anything shorter, it might not be the smartest investment.

Good RV Portable Generator Brands

When thinking of buying a new RV generator, it can also be helpful to look at the most popular brands. It’s the brands that have been on the market the longest and which have shown that they care about providing high quality products with the most advanced features. So, here are some of the best brands in the industry:

  • Honda is a well known brand in the automotive industry and it’s also one of the most popular brands in the industry of portable generators.

How to Connect a Portable Generator to Your RV?

To connect a travel trailer or RV to a generator, you need to set up the right connections. It will ensure seamless power delivery to your vehicle’s appliances and will eliminate the risk of electrical hazards caused by poor cabling. Here’s a guideline on how to use a generator with an RV. However, keep in mind that these are just general guidelines. Consult the manual that comes with your generator product for more specific instructions.

  1. Start by finding a good location for your unit. The place should be firm and steady. And it should be able to support the weight of the generator. It should also be level so that the unit doesn’t tip over during operation. Some RVs come with a built-in tray specifically for generators. If your has it, you can set up your unit there.
  2. Next, you need to fuel the generator. Most products come with a special tank for fuel, which needs to be filled up before use. And always make sure to use the type of fuel that is specified for your particular unit.
  3. Drive the grounding rod into the ground and connect the copper wire from the grounding rod to the unit.
  4. Make sure that the generator’s exhaust is facing in the opposite direction from the RV and people in order to avoid carbon monoxide poisoning.
  5. Connect the RV cable to the generator. Start your generator and you should have power in your RV right away.

How to Maintain Your RV Generator?

Once you’ve bought your perfect generator and you’ve connected it to your RV, your next step should be to understand how to maintain it in good condition. With proper maintenance, you’ll be able to keep your unit in top notch condition for much longer. This means less frequent fixing of any issues and longer use without having to replace them. Here are some tips for proper usage and maintenance.

  1. Change the oil. As with any engine-powered, oil is used for lubricating all the internal workings of a motor. Without it, the metal on metal contact will cause the motor to wear out very quickly. That’s why it’s important to regularly change the oil, which will ensure that friction stays lubricated and cooled. As a result, it will also make sure that the engine continues to run as efficiently as it can.
  2. Keep the tank filled when in use. You don’t necessarily need to fill up the fuel tank every time you use the generator. However, you never want to run the generator to the point that it has completely run out of fuel. When that happens, your appliances start to drain the magnetism from the generator’s coils. This can result in irreparable damage and can shorten the lifespan of your unit.
  3. Charge the battery. Not all RV generators come with a battery. However, if it does use batteries for electric start, make sure to keep them always charged. Imagine that you need to take out your generator in an emergency situation and then you find out that the battery is dead. Doesn’t sound like an ideal situation, right? So try to plan ahead and you’ll have your generator ready for use when you need it the most.
  4. Avoid overloading. Generators are made to provide a specific number of watts. And if your appliances are demanding more electricity than the unit can produce, it overloads the system. Generators typically have a built-in overload protection feature designed to cut off the power before any damage is done. However, you’re still putting it at risk of avoidable wear and tear.
  5. Proper storage. When you’re not using your generator, store it away in a cool and dry place. Choose an area that is free of moisture and any other form of liquid. Moreover, cover your generator to protect it against dust, mud, and grime. When putting away your generator, also be sure to drain all the fuel from the tank. You don’t the fuel to be stale when you start using it again as it results in generator breakdown. Additionally, during inactivity, exercise the unit every one or two months. Just run it for a few minutes so that the oil can spread out throughout the engine and get everything well lubricated.
  6. Do regular servicing. Getting your generator regularly serviced will ensure that it will continue to run efficiently for a prolonged period of time without the risk of a breakdown. Take it to the nearest repair shop for a checkup of any deficiencies or issues.
  7. Clean the batteries. If you see any dirt piling up, wiping it away with a damp cloth. And if you notice any corrosion at the terminals, disconnect the cables and clean them while also being careful not to get any moisture into the battery cells.

RV Generator FAQ

Do travel trailers have generators?

Most travel trailers don’t come with a built-in generator since they do have a limited amount of space. The only RVs that do usually include a built-in unit are the 5th wheels and motor coaches. In all the other cases of RVs, the owners can add a portable generator.

Which type of fuel is the best for an RV generator?

The ideal type of fuel is dependent on the type of RV that you have or the type of application that you’ll be using it for. For example, if your trailer has a diesel pusher, you might want to get a diesel generator. This type would also be more suitable for you if you need maximum power.

However, in most cases, RV owners get a propane or gas unit. Gasoline generators are more affordable, more efficient, and compact. Propane units are more environmentally friendly, producing clean emissions. This fuel also has a longer shelf life, giving you more run time on a single refill. The downside, though, is that the tank size is usually smaller compared to other types.

How to start an RV generator?

The process for starting a generator depends on the specific type and model you have. Most units offer an electric start, so to get the unit running all you need to do is push a button. Some generators offer a more convenient option with a remote start. It allows starting the unit from anywhere in your RV by using wireless remote control. And the conventional start is recoil, which requires pulling a recoil rope. This type of start is included in all portable generators, either as the main start or as a backup option.

What is the difference between surge watts and running watts?

Surge watts refer to the amount of power needed to start larger appliances, such as an air conditioner, power tools, or refrigerators. Such appliances need a short brief boost of power, which would get the motor going. And once the motor has started, the wattage slowly goes down to the running watt level. So, running watts are the amount of power that is required to continuously run the appliances.

What size generator do I need for my RV?

This is probably the main question RV generator buyers have since the right size will ensure that you have enough to power all the appliances of your RV. To determine the size, make a list of all the electronics and appliances that you wish to operate in your RV and calculate the number of watts that is needed to power them. Also, don’t forget that many larger appliances have higher starting watts, so take that into account as well.

In all, sum up the watts needed for each of the appliances and go for an RV generator size that is slightly higher.

What size generator for a 30 amp RV?

If you’re looking for a portable generator for a 30 amp RV, consider the models that offer an output of 3,000 to 3,600 watts. Anything below might not give you enough power and anything above will be just wasted.

What can a 4,000 watt generator run?

With a 4,000 watt generator, you’ll probably be able to power most of your RV appliances. It can power a couple of larger appliances along with smaller devices simultaneously. For example, you could power an AC unit, a refrigerator, a microwave, coffee maker, phone, and laptops.

How much gas an RV generator normally uses?

RV generators can run on either propane, diesel, or gasoline. The advantages and disadvantages of each of these we’ve discussed in the fuel type section above. What we haven’t mentioned yet is how much fuel does a generator consume when in operation.

There’s obviously no specific number applicable for all units since it depends on the fuel type, load, and efficiency of the generator. However, on average, a 6000 watts propane generator will consume about 1.5 gallons of fuel per hour. A diesel generator with the same amount of power output will consume about 1 gallon per hour. And the same goes for gasoline generators. They also consume about 1 gallon per hour.

These numbers are just averages and to get a more specific number, you can check the specifications sheet of the model you have. But then again, that will also be just an estimate. The actual number will still depend on the amount of load put on the generator and the age of the unit.

Where to buy an RV generator?

You can buy RV portable generators in RV supply stores and local dealerships. Alternatively, you can also buy them online. And if you want to find a wide range of options, a good place to check is Amazon. There, you can also compare and read RV generator reviews to get a better idea about each of the products.

How long will an RV generator last?

On average, portable generators last about 10,000 to 20,000 hours of operation. However, the actual lifespan of a unit can vary due to a number of factors. First of all, it depends on the quality of the generator. A poor quality generator will obviously not last long. Secondly, it depends on how well the generator is maintained. If you follow proper generator maintenance and servicing of the unit, it will last you much longer.

Do I need an adapter for an RV generator?

If your generator comes with an RV ready outlet, you’ll be able to connect your RV directly to the unit, which will provide electricity throughout the vehicle. However, if there’s no RV outlet on the generator, then you will need to additionally purchase an adapter.

How quiet should an RV generator be?

If you’ll be staying at a campsite, you’ll be surrounded by neighbors that you wouldn’t want to disturb with too much noise. Besides that, you’d rather be enjoying the quietness yourself and most national parks also have noise limitations. That’s why it’s important to choose an RV generator that would produce minimal noise. An optimal unit would have a noise output of about 60 decibels at 50 feet.

Are propane generators quieter than gas?

Generally, propane generators are quieter than gas. However, the type of fuel isn’t the only determining factor on how much noise a generator makes. It also depends on how old the generator is, the type of engine used, the technology that the unit is equipped with, and the amount of load.

Will a 2,000 watt generator run an air conditioner?

A 2,000 watt portable generator is capable of powering a 10,000 BTU air conditioner. However, it’s still recommended to get a generator with a bit more power output. A 10,000 AC unit requires 2,200 surge watts and 1,500 running watts. So, it would be better to get a generator with at least 2,200 surge watts rating. And if your AC unit has a higher BTU rating, your generator power output should also be accordingly higher.

Can you run an RV generator while driving?

Yes, it is safe to run your generator while driving the RV. However, there are a few things to keep in mind in order to avoid problems.

If you have a propane fueled generator, check your local and state laws, as some may prohibit the use of propane while driving. Some laws may even prohibit carrying propane onboard when driving on certain roads, bridges, or tunnels. And if you want to run your generator while driving, it’s better if it’s a built-in type. Portable generators can also be run but then you need to make sure that it’s properly covered and well fastened so it wouldn’t roll away.

How to make the RV generator quieter?

A loud RV generator can quickly turn your camping trip into an unpleasant experience. On top of that, it can become a real annoyance also to your campsite neighbors. If you find that your generator is making too much noise, there are a few things you can do to make it quieter.

The cheapest and simplest option is to get a noise reduction box. Other ways of quieting it include adding a generator muffler, soundproofing the onboard generator compartment, or replacing the old generator with a new quieter one.

If you want to avoid loud generator operation, consider getting RV solar panels instead. They will provide you with clean energy and will do so without producing any noise.
