8 Best Travel Trailer Generator Reviews 2023

1. Generac 7127 iQ3500 3500 Watt Portable Inverter Generator

The Generac 7127 iQ3500 is an impressive portable generator for camper units, travel trailers, fifth wheels, and motorhomes without built-in power-generating appliances. It has a robust design and a whisper-quiet operation that shames the leading brand.

According to marketing flyers, this product is 40% quieter than generators with Honda’s patented Advanced Inverter technology. I know that the Honda EU2200i has a noise level of 48 to 57 dB, and this product comes in at about 45dB. If people do not consider that impressive, I do not know what is.

This quiet generator for camper units is perfect for boondocking with other RVers. Moreover, its generation capabilities deliver 16% more power than the Honda EU3000IS. I can think of many motorhome appliances I can operate with this product providing electricity.

I also admire this model’s user interface. Although small, the LCD delivers the correct information to make operation more convenient. I can effortlessly check the fuel level, wattage, remaining runtime, hour counter, and generator status. It is perfect for RVers who want an easy-to-operate device.

Where other machines have three separate dials for starting, running, and stopping the generator, this device only has one. I also appreciate the extra USB ports for powering up my mobile devices. Digital nomads can turn the campsite into their temporary office and never worry about running out of electricity.

Unfortunately, I find this generator heavy. At 109 pounds, this machine somehow defeats the idea of a “portable” power generator.

  • 16% more power than the leading brand
  • Ultra-quiet operation, producing only 45dB
  • Intuitive user interface with information like fuel level, runtime, etc
  • Convenient three-in-one control dial
  • Multiple ports for simultaneous power deliver
  • Heavy at 109 pounds
Still, the ultra-quiet operation and exceptional power delivery remain the best selling points for this generator. If it beats a leading brand in both power and noise level, issues in portability are inconsequential.

2. Champion 4000-Watt RV Ready DH Series Generator

A backup power supply can prevent your appliances from getting interrupted and breaking in the long run. This is where the Champion 4000-Watt RV generator comes in the picture. It is capable of meeting your basic RV electricity needs and even more.

A powerful device like this one is all I need as a reliable backup power source for my RV. This inverter generator’s 4000-watt power is packed with tons of useful qualities.

Its 4000-watts power capacity allows me to power up all desired appliances in my RV, including the heavy ones such as the RV air conditioner, with clean electricity.

I expected this powerful machine to make a lot of noise. Surprisingly, this inverter generator runs rather quietly at 68dBA. Since the device uses an advanced open frame inverter design, it is quieter and lighter than a regular Champion generator. Hence, it is perfect for enjoying a good night’s sleep while running the appliances through this product.

To enjoy even more power from this machine, I can make a parallel connection with two 2800-watt inverters or one higher one. Besides, it also features an Economy Mode to extend engine life.

While this generator can carry heavy equipment, it has a pretty long run time of about 17 hours at 25% load. However, it takes 2.9 gallons of gasoline to fill up its fuel tank.

  • 4000-watts power, enough to power heavy appliances
  • Comes ready for an RV connection with a 120V 30A port
  • Runs quietly at 68dBA due to the advanced open frame inverter design

For RVers with heavy appliances like me, I highly recommend this inverter generator. With the Champion 4000-watt inverter generator at your disposal, you could live in full comfort in your RV while boondocking or camping.

3. Champion 3400-Watt Dual Fuel RV Ready Generator

Choosing a reliable power generator for RV is not easy. You have to see its performance first before deciding. In terms of performance, nothing beats the Champion 3400-Watt Dual Fuel Inverter Generator for providing quick and sustainable electricity for RV.

I am impressed with this power generator. It is relatively easy to use, and all outlets and buttons are well designed and properly labeled for easy understanding of their functions. Furthermore, its RV dedicated outlet also lets you easily connect your RV without the need for additional equipment.

This inverter generator provides 3400 watts and 3100 watts of clean starting and running power, enough power to power an RV air conditioner plus other essential appliances and sensitive modern electronics. What’s more impressive is that I can connect it to another Champion 3400-Watt Dual Fuel inverter to have access to 6800 watts of power!

Apart from that, this machine also operates quietly at less than 60 dB of noise production, ensuring you are not bothered by its running.

This efficient machine comes with an incredible feature: its ability to run on two different kinds of fuel; propane and gasoline. It allows me to run the generator continuously for an extended period while alternating fuel sources. In detail, it runs for 7.5 hours with gas and 14.5 hours with propane, at a 25% load.

The only downside is that it is not resistant to adverse weather. I cannot leave this generator outside of the RV, especially if it is raining or snowing. While setting up a generator tent could easily solve this problem, I still see it as an additional hassle.

  • Outlets and buttons are well designed and labeled for easy understanding
  • Comes with a dedicated outlet for breezy connection
  • Allow connection to a Champion 3400-Watt Dual Fuel inverter to double the output power
  • Operates quietly at less than 60 dB of noise production

  • Not weather resistant
All in all, I can say that the Champion 3400-Watt Dual Fuel RV Ready Generator is an exceptional product. This generator can offer you all the value for your money and remains one of every RVer’s favorite choice.

4. GENMAX GE-3300A Portable Inverter Generator

People love the Generac iQ3500 because of its super-quiet operation and remarkable power-generating capabilities. Unfortunately, its heft can be bothersome to some folks, making this GENMAX a more suitable option.

Measuring only 17.3 inches tall, 11.5 inches wide, and 18.9 inches long, it is nearly half the volume of the iQ3500. Storing this generator in an RV compartment is never a problem because of its space-saving design.

It also weighs only 47.3 pounds, which is 130% lighter than the Generac iQ3500. I can carry this virtually anywhere and never worry about powering up my devices.

I am also impressed by its fuel economy. RVers can activate the ECO Mode and let this generator run for eight hours using only a gallon of fuel. My current generator is a gas guzzler, consuming more than three gallons to cover seven hours of continuous operation. With today’s skyrocketing oil prices, this product’s fuel efficiency is welcome news.

Some RV owners might have issues with this generator’s 3,200-watt rating. They can double the output by linking two GE-3300A in parallel, using a kit from authorized retailers. The product’s expandable design differentiates it from other generators that only operate as standalone units.

Compared to the Generac iQ3500, this generator is quite noisy. Nevertheless, its 62dB noise level at 25% load is still quieter than the 80dB-plus noise ratings of conventional products. Cranking this device to maximum power also amps its noise to 68dB, still comfortable to the ears.

I would have given this small RV generator five stars, but its user guide prompted me to strip one. The company did not bother proofreading the manual to polish its instructions, which is a shame for a brand that wants to compete against the world’s best.

  • Lighter and more compact than other portable generators
  • Fuel-efficient design for maximum savings
  • Can be linked to another generator in parallel
  • Quiet operation (62 dB to 68 dB)
  • User guide could be better
Despite its issue, this product remains an excellent choice, especially for RVers who need a lightweight generator they can bring anywhere.

Regarding power generators, most of the time, efficiency and quietness do not come hand in hand. If you’re in search of an inexpensive and efficient portable generator for use in your RV, the WEN 56380i Inverter Generator may be the right one for you.

Most other inverter generators within the specification range of this machine are quite pricey. The Wen 56380i, on the other hand, is rather cost-effective, thus offering you great value for your money.

Since this generator was explicitly made for RV enthusiasts, there is hardly any installation or extra cables needed to use with RVs. I could just connect the generator to my RV using an RV extension cord to enjoy 3400 running watts of clean power. Remarkably, the model is large enough to carry everything in my RV.

It also comes with both manual and electric startups and cranks up pretty quickly. I am thrilled to know that the noise produced by this generator is just about 57dB at a 25% load. Such a noise level does not disturb our sleep and is not a nuisance in the camping area.

While this generator is fuel-efficient, I can only get a steady 8.5 hours supply of clean electricity at a 50% load. This run time is a bit low when compared with other inverter generators of its specification. Nevertheless, its run-time is still enough for basic needs.

The plus point is its lightness and portability, allowing you to carry it anywhere power is needed. This Wen generator also comes with a fuel shutoff to utilize the carburetor’s leftover fuel before shutting down, thereby maximizing its lifespan. It also allows for parallel connection.

  • A cost-effective investment for a generator for travel trailer

The Briggs & Stratton P2200 PowerSmart Generator meets all the basic requirements of a sound generator, with little extra helpful features.

This inverter generator can deliver a steady supply of clean electricity to your RV while doing so very quietly at about 59dB when placed seven feet away. This generator is a bit heavy compared to other generators within its specifications, but it is still portable.

More importantly, its supply of 2200 starting watts and 1700 running watts may not be sufficient to simultaneously carry heavy appliances in your RV. However, it can comfortably power all the necessary equipment. If you require more power for your RV, you could connect another Briggs & Stratton P2200 inverter to get 4400 watts starting and 3400 watts running power.

This machine features different power outlets, including a 12V DC port that makes it easy to plug cell phone or tablet chargers or other 12v sources. It also comes with USB ports to let you charge your devices quickly and stay connected.

With one gallon of fuel, you can get clean and steady electricity supply for up to 8 hours at 25% load. While running, it produces less than three percent total harmonic distortion, making it safe for modern sensitive devices like laptops, TVs, and game systems.

While I’m generally impressed with this generator’s features and initial performance, I noticed that it could not run multiple heavy appliances simultaneously. I have to unplug other devices to give way to a piece of heavy equipment, such as the air conditioner.

I was not expecting much when the Pulsar 2300iS was delivered as it was a low-priced model compared to the name brands I have. I immediately started testing it as soon as it arrived. I poured the included oil, added unleaded gasoline, and fired-up the engine. It started on the first try. But pouring the oil was somewhat troublesome and spilled a bit, so I attached a hose to the funnel and cleaned-up first before proceeding.

The sound is close to my other portable generator. I’m sure you wouldn’t get complaints in a crowded trailer park as it is relatively quiet but loud enough to hear it running fine.

I added load every thirty minutes until I plugged my AC, and it still ran properly for the whole night. The Economy mode can run my TV and other small electronics simultaneously along with a small refrigerator longer. In detail, there are two 13A outlets, one 12V outlet and a 5V USB port for you to charge your devices.

Afterward, I checked the spark plug if it needed cleaning. This proved to be a bit of a chore since it was hard to access and could probably injure me if I’m not careful. But it was serviceable, and I even checked online for parts and found some. So repairs a few years down the road would not be a problem.

It can run in parallel to another unit for more power, so I’ll just buy another one as it’s more convenient than having a bigger generator to lug around. Still, it is not all-weather proof, so get a cover if you leave it outside during storms just to be safe.

  • A low-priced model with great functionality
  • Easy to use with minimal assembling
  • Does not disturb you and other campers with excessive noise
  • Runs RV devices properly with multiple outlets
  • Serviceable with parts available online

What to Look for When Buying a Generator for Travel Trailer


The best camper trailer generator is worth one’s peace of mind. It must keep the AC running while traveling. It would be even better if the fridge can preserve packs of sausages and ice-cold beer.

If you like how that sounds, investing in a good generator is a must. Here are four things to consider when buying a generator for a travel trailer.

Power Output or Wattage

Understanding your needs is one of the first things when buying generators for travel trailers. Different appliances require differing power outputs. Some appliances also take more watts when starting than what it does to run continuously.

For one, air conditioners will take the most wattage in a trailer. The usual air conditioners of about 13,500 BTU needs approximately 2800-3000W to start and about 1500-2000W to keep running. An RV fridge needs 600 starting watts, then 180 running watts. This means a 3000 watts generator is enough to start the air conditioner, but it takes little waiting time to start the RV fridge.

It is also worth noting that while the generator might give up to 3000W to start the air conditioner, in the long run, it might only run at 2600W.

Size and Weight of Generator

If you value your comfort and plan to add things like a microwave or a TV, a larger generator is probably needed. Adding more appliances requires more power. That brings us to the next factor to look out: the size and weight of the unit.

While wheel kits are usually a standard option for larger generators, moving it in and out of the trailer is still an important thing to consider. Not just in your travels, but also when maintaining it during a slow season. It is possible to opt for two lighter ones. Linking two 2000W generators will allow more power for a more lightweight design.

Noise level

Relaxing amid a serene environment is one of the benefits of camping. Of course, you don’t want your generators for rv trailers to keep you from enjoying these moments with its loud noise. It is also within good etiquette to consider your g

enerator’s noise level when joining trailer camps. It is crucial to know that there are two styles – the conventional and the inverter. In terms of noise level, conventional types are usually louder and heavier, while inverter generators are generally quieter but pricier. But these two styles have more differences than just the noise level. That leads us to another important thing to consider.

Type of Generator Fuel

Travel trailer generators can run on three types of fuel. It can either use diesel, gasoline, or propane. Some generators can use two types of fuel, which is a good backup plan when traveling long distances. Knowing which type of fuel is more convenient or easier to find while on the road is also an important thing to consider when buying generators.

Fuel Efficiency

Like mentioned earlier, the two styles of trailer generators also vary in their use of fuel. Conventional generators have engines that are running at a fixed speed and in full throttle constantly. That means more stops to refill the gas tank, or more storage is needed for extra fuel. Either way, it can be a hassle for long travels.

On the other hand, an inverter generator can power its engine up and down to meet the trailer’s needs. This makes it a more efficient choice in terms of fuel usage. It is also worth mentioning that these kinds of generators produce lower emissions for carbon footprint-conscious individuals.

Other Important Factors to Consider


Aside from the things that you need to look for, there are more factors to consider when buying a small travel trailer with generator. Let us look at some crucial aspects to check when it comes to investing in a generator.

What is the best generator for a travel trailer?

Most modern RVs today have built-in generators in them that can power the appliances that come with it. On the other hand, for adventurers that are into boondocking with campers, it is well recommended to invest in additional security generators.

With the many brands, variations, and factors to look at, what would be the high quality generator to buy for a travel trailer? It depends on your needs and preference. It is better to pick one that is right for the mobile home you have.

To narrow your needs, answer questions like how long is the travel or how much power does the trailer usually need? With all the appliances you plan to bring, how big of a generator is required then? Will it be better to carry one bulky high-powered generator or a lighter two lower-powered units connected with a parallel cable? Can you easily work around the technical aspects of it? What size generator for travel trailer?

The general rule would be to ensure that the generator’s power is enough to sustain your whole trip. Knowing the wattage needed to start and run the trailer’s appliances will provide an approximate of the required amount of power output. By understanding your needs, it will be easier to identify the best generator for camper trailer.

How do travel trailer generators work?

A working generator should start effortlessly and swiftly. Then, it should automatically run smoothly and efficiently. There are four functional sections in a travel trailer generator: the fueled mechanical motor, a fuel supply system, an electric starter motor and an electric power generator.

Generator motors can be fueled with diesel, gasoline, or propane. The internal combustion of the fuel moves the crankshaft of the motor to make it a spin. Different types of fuel combust in different ways, so it’s important to know what kind of fuel the generator runs on.

Then, the mechanical energy created as the crankshaft spins forces electric charges’ movement until the generator starts and runs. The flow of electric charges through the circuit can now supply the AC voltage needed by appliances. When you connect to the output wires of your generator, you draw power from this whole process.

What are the different types of travel trailer generator?

There are two types of travel trailer generators, the conventional and the inverter type. Conventional generators are those that have been tested and proven through time. They can operate for a long time and can rate from 500W to 50,000W. These are also generally cheaper options. Although very reliable, these classics are bulky, noisy, less fuel-efficient, and produce lesser quality power output than the other type.

On the other hand, inverter type generators are the light and portable units. They can also run for long times and are much quieter options. These are designed to use fuel efficiently and produce high-quality power output. But since these are generally small travel trailers with generators, they have less power output and are typically expensive.

Why do you need a generator for a travel trailer?

Travel trailer generators provide an extra energy source for things you want to enjoy while out in the wilderness. It can power the AC without a problem and let you travel in comfort.

The most trusted travel trailer generator can power a fridge, an electric grill, or even a slow cooker for a nice picnic out in the woods. It can provide extra entertainment for long travels. Generators can power your TV or let you use cellphones and laptops without worrying about going out of battery.

There’s no downside to having extra power in your trailer. Furthermore, the peace of mind of having power when you need it is more than enough reason to have one.

Generators are handy equipment to have in a travel trailer. If you are looking to buy one, make sure you’ve considered these factors in choosing.

Yes! Some travel trailers have already come with generators. Additional generators are usually needed for those who want to carry and use more power in their travels. For those looking for the best generator for travel trailer, consider the space available in the travel trailer when buying one. It is important to find a generator that will fit and be easy for you to manage.

What is the quietest generator for 50 amp RV?

The Duromax XP12000EH and DuroStar DS12000EH are two of the quietest camper generator units for 50-amp RVs. These products have a noise level of 74dB, which is about as loud as a vacuum cleaner or a little noisier than normal conversation.

The Firman P08003 also has a 74dB noise rating, but only at half load. Hence, you can expect this generator to have a louder operation at full blast.

How big of a generator do I need for a 50 amp travel trailer?

A 50-amp travel trailer can handle a maximum of 12,000 watts of electricity. These recreational vehicles have shore power cords with two 120-volt live wires for 240 volts. Multiplying 240 volts by 50 amperes results in 12,000 watts.

Hence, owners of travel trailers with a 50-amp electrical system may pick a similarly-sized generator for RV or a unit with a slightly higher rating (i.e., 12,500 watts).

That said, if you use less than 12,000W, you can go lower.

How do I calculate what size generator I need?

Calculating the correct size generator for 5th wheel is easy.

The first step is to determine your RV’s overall power consumption. You might want to use an ammeter or a similar device to measure the electrical consumption of each appliance in your motorhome. List the itemized measurements and compute the total wattage.

If you cannot find the wattage, but voltage and ampere ratings are available, you can compute the watts by multiplying amps with volts.

Check your RV appliances to determine which has a starter motor. These devices require more electricity to activate before it whittles to an operating current. If the information is unavailable, you can estimate the surge wattage by multiplying the appliance’s wattage rating by two. For example, a 300-watt device needs 600 watts to start.

Next, you must combine all running and surge wattages and determine the highest number in your list.

Can you use a regular generator on an RV?

Yes, you can use a regular generator on an RV, as long as it meets your motorhome’s electrical requirements. For example, if your RV needs 3,000 watts to run all appliances, a 3,500-watt regular generator should be sufficient.

Unfortunately, this type tends to be noisy, which can annoy other RVers. It is also heftier and bulkier, making storage and handling a two-person chore.

A portable RV generator is a better solution, especially for families with modest electrical energy needs. Its noise levels are ideal in crowded camping areas, while the compact size and lightweight design are suitable for backpackers and other outdoor adventurers. Portable products are also more affordable.

How to install and use?

Inspect the mobile home where the generator would be most convenient to mount. Some vehicles have room at the front. Putting it in the front is said to be the best method to install generators. It allows for efficient traveling, especially with larger and heavier units. If no room is available at the front, the rear of the trailer is also an option. The bumper of your mobile is also a possibility for external mounting.

Some trailers need a support structure and a platform to hold the generator. There are A-frames available online to mount generators in a trailer easily. Note that the exhaust of the generators should have enough space to breathe.

When the travel trailers generators are installed, the electrical systems can now be connected to have a power source ready to be used.
