The challenge is buying a model that’s capable of holding up its end of the bargain. With many products on the market, picking the best 30 amp generator might be a struggle.

To make things easy for you, we have assembled the best of the best units in this category based on in-depth research, testing, and more. Power on!

Comparison Table

What is a 30-amp Service?

This is often used to describe the current input possible for an RV. And since the RV has a voltage rating of 120 V, it can’t exceed a 3600-watts input with 30-amp service.

The maths is a simple one: 30amp x 120V = 3600 watts.

You can’t have a 30-amp service without the TT-30 plugs and a specific 30-amp breaker.

If you exceed this wattage capacity, the 30-amp circuit breaker in the RV will be tripped to prevent overheating sockets and damaging your appliances.

If your RV requires a 30-amp service, then generators with the right power output are recommended. RVs with such a service can depend on the 30 amp generators for all their energy needs without any electrical problems.

While not all RVs demand a 30-amp service, most belong in this category. Regardless of the power restriction, basic appliances like TVs, refrigerators, air conditioners, and others do fit perfectly.

However, you might just have to manage your use of the devices to ensure the power consumed doesn’t go overboard.

Unlike the previous generators considered, the Champion 3400 is an inverter generator. Its 192cc engine can be powered by gasoline and propane, so you aren’t limited in that area. This is despite its small size.

Power output is relatively constrained compared to other units. The Champion 3400 has a peak power output of 3400 watts and a running power output of 3100 watts, which should suffice in getting your RV appliances to function optimally.

It’s hard not to notice the wedge-like shape of this generator. Despite this unusual shape, the generator is equipped with handles and a pair of wheels, so you should have a problem moving the inverter generator to your preferred spot. The Champion 3400 is portable, alright, but its small size means you might have to lift the unit sometimes, so the 95.7lbs weight is such a relief.

Tank size could decide how long a generator runs, and this inverter kind has a 1.6 gallons capacity.

Yes, it’s not that big when compared to other generators considered earlier, but the 7.5 hours runtime obtainable on a 25% load is far from a killjoy. And that’s not all as a full 20lbs propane tank offers a whopping 14.5 hours runtime on the same load.

Picture such a small unit compatible with your RV and offering such amount of power, it’s indeed commendable. There’s also the opportunity of leveraging unique modes like the economy mode to stretch the runtime even further.

Besides its runtime and power output, the Champion 34000 delivers a near noiseless operation. Its 59dB decibel rating, which is much lower than previously reviewed generators, suggests that a noise-free camping or tailgating adventure is possible.

Everyone desires a peaceful RVing with only the chirping of birds to listen to, and this unit might just offer such a luxury.

A lot of our gadgets are sensitive to any fluctuations in power output, but we need to have them on our RV. While most generators might provide the power that can serve most basic appliances, sensitive one requires something with a low distortion factor.

The Champion 3400 has doesn’t just offer power but a relatively stable one as indicated by its below 3% distortion factor. So you can use this generator for those sensitive appliances while RVing.

It’s always a joy to see a compact generator that appears to punch above its weight, and that’s the case with the Champion 3400.

Despite its small size, you are availed with two options to start the generator. You can opt for the electric start, which gets the unit running when you depress a button.

There’s also the recoil start, which is quite handy when the battery is down.

    • Can use two distinct fuel sources which improves the versatility of the generator
  • Massive runtime, made possible its dual-fuel capability, so you enjoy the luxury of your RV appliances for longer than you can imagine
  • Noiseless operation removes the inconvenience of listening to a generator rambling while camping or tailgating
  • Perfect for sensitive devices thanks to its low distortion factor

Why We Pick This Unit

We liked the portability of the Champion 3400. It wasn’t only small, but you could deploy its wheels and handles in carrying the generator around.

We were lukewarm regarding the wattage of this unit – its 3100 watts rated output wasn’t overly special. But we found the dual-fuel capability on such a small generator to be a worthwhile addition.

We were disappointed by the 1.6-gallon tank capacity, then its 7.5 hours runtime on a 25% had us backpedaling instantly.

We are impressed by the noise level of the generator – 59 dB decibel rating wasn’t bad for such a unit. We believe the Champion 3400 is a generator underdog that’s punching above its weight, but it’s knocking down opponents that are way more costly.

The Champion 3800 is a powerful unit as affirmed by its 4750 watts peak power output and running power output of 3800 watts. This should suffice for the convenient use of the appliances in your RV.

Like the DuroMax generator considered earlier, this Champion unit has a highly flexible dual-fuel capability. The 224cc engine can use either propane or gasoline to deliver the power needs in your RV.

Regardless of the fuel source you opt for, the generator is capable of delivering a runtime of at least 9 hours, depending on the quantity of fuel used and the load on the generator.

Sequentially use both fuels, and the unit could last almost a full day. That’s your RVing experience taken to a whole new level.

The Champion 3800 has a gasoline tank capacity of 3.4 gallons, which holds a significant amount of fuel for a decent runtime.

While the generator has a substantial size, it’s still quite mobile. This is made possible by its pair of wheels and handle.

The handle is a sturdy appendage on the cast-iron frame, which helps in transporting the unit without any problems. And this appendage can be folded when it’s no needed. Boondocking at a remote campsite just got better.

The Champion 3800 can be started quickly with a single touch. Being equipped with a battery ensures you can push a button, and the generator roars to life.

There’s still a recoil start, but that’s relegated to the background as pulling at a cord isn’t something that appeals to a lot of RVers.

Starting generators can be a problem in the cold. Fortunately, the Champion 3800 has its novel Cold Technology which makes it easy to start the unit, regardless of the drop in temperature.

One of the attributes of camping in the middle of nowhere is the irregular terrains you have to deal with. You’ll need a generator that wouldn’t feel like a fish out of water in such an environment.

The Champion 3800 has a cast-iron sleeve, which gives the generator that roughed build that’s great for the outdoor.

If a generator becomes short on oil without any replacement being made, the engine could get damaged. The result is an expensive repair, which can be quite difficult when boondocking.

With the Champion 3800, a significant drop in oil level prompts the generator to shut down, preventing the need for any inconvenient repair.

You’d expect the noise level of the Champion 3800 to be rather low, as suggested by its 69dB. Unfortunately, this is only obtainable from a distance of 23ft.

If you’re RVing, keeping the generator at a considerable distance is crucial if you don’t want to deal with the noise.


  • Cast-iron sleeve ensures it survives the roughest of terrains
  • Dual-fuel capability removes the limitation of gasoline
  • Foldable handle and sturdy tires help make the generator easy to mobile
  • One-touch start makes it easy to get the generator running
  • Intelliguage meter keeps you updated on runtime
  • Generator shuts down when the oil becomes too low


  • The carburetor is bedeviled by issues
  • Noisy generator

Why We Picked this Unit

We found the Champion 3800 to be quite the portable generator. Its 3800 running watts wowed us considering its size. Being able to use either propane or gasoline on this generator was something we were pleased with.

We feel Champion exaggerated how silent the generator is – the 69dB was from a distance of about 23ft, which is unreasonable.

For us, there wasn’t anything out of the ordinary with the 9 hours runtime of the Champion 3800. We believe its runtime is commensurate to the 3.4-gallon tank size, so it’s expected. But we like the generator’s cold start technology for the ease of starting the unit under blistering cold weather.

4. DuroMax XP4850EH – Best value for money

​DuroMax XP4850EH Generator

The ease of switching between these fuel sources is also impressive – you don’t have to waste valuable time moving from running on gasoline to propane.

The DuroMax generator has a gasoline tank capacity of 3.9 gallons. While on a 50% load, this unit’s 10-hour runtime on gas isn’t shoddy. With propane, you get a smaller runtime of around 8 hours, which is still great on the 50% load.

Let’s face it; the XP45850EH has a bulky appearance. Yet, it’s still highly mobile due to the included wheels and handles.

There’s no need to lift the generator just so you could get it outside the RV, near a job site, or just outdoors for a backup service. Pushing it along is so much easier.

Starting the generator is possible through two different means. You can either get the engine started using the electric start – there’s a battery that helps in that regard.

The recoil start is also possible, and you don’t have to pull at the cord multiple times as long as the unit is properly maintained.

To ensure the generator meets your power needs, this model is infused with the DuroMax MX2 technology, which is geared at providing maximum power to your RV or power tool. You will have to use the 120V receptacle on the generator to get this power boost.

With its all-metal framework, this generator can weather the rigors of everyday use in different terrains – a prerequisite of any RV generator.

While this isn’t an inverter generator, it has an inbuilt surge protector to avoid the damages that arise due to power surges.

  • Durability issues

Our opinion/why we choose this product

We found the power output of this generator to be impressive. 3850 watts rated output is great for its price range. While we couldn’t be bothered about the size of this DuroMax generator, we were pleased with the wheels and handle as it makes moving the unit less chaotic.

We like the dual-fuel capability of this unit. Its 8 hours runtime a 50% load wasn’t bad, but we expected more from a 3.9-gallon tank size. We found this generator to be a decent buy.

5. Yamaha EF3000iS – Best Reliable generator 

​YAMAHA EF3000iS, 2800 running Watts/3000


  • wattage : Starting 3000 W / Running 2800 W

  • Noise : 53 dBA
  • Run time : 19 Hours Continuous
  • Starting Method: Pull Start
  • Type : Inverter

More Features: Sturdy design, Ultra Quiet, Extremely Fuel Efficient, 3 Years Warranty

This Yamaha generator might not be the most powerful on this list of 30 amps generator reviews. Its 3000 peak power output and the rated wattage of 2800 watts should suffice in keeping those convenient appliances working in your RV.

Like most of the generators considered earlier, the EF3000iS is quite the compact unit.

It has two different pairs of wheels, though not the conventional wheels on most generator models; you can still move the generator with these tires.

There’s a parking brake to improve the ease of transporting the generator. Both ends of the generator have handles which help in the transportation of the generating set.

However, you might want to restrain yourself from lifting this generator due to its 136 lbs weight.

This Yahama generator has a tank size of 3.4 gallons. While the brand promises more than 18 hours of runtime on a full tank, you have to take that with a pinch of your favorite seasoning as there’s a lot involved.

This runtime is only feasible on a 25% load, and the Smart throttle needs to be active. You can’t use more than a handful of appliances at such an output.

One of the unique things about this generator is its gasoline petcocks on both sides of the unit.

This is especially useful for keeping the carburetor clean, reducing the fears of a generator that could need servicing while Boondocking in the middle of nowhere.

The EF3000IS is an inverter generator, so you can expect some stable electricity for your sensitive appliances.

Unlike the other inverter units reviewed earlier, this Yamaha generator uses a pulse width modulation control to achieve a really low distortion factor, delivering a power output that’s ideal for the most sensitive of appliances in your RV.

The Yamaha EF3000iS doesn’t make a lot of sounds even during peak levels. Its 53 – 60 dB rating confirms its low noise levels, and this could be due to the generator’s unusual fan and muffler.

You can enjoy using your preferred appliances without having to contend with the noise generated by the unit.


  • fewer maintenance demands as gasoline petcocks remove stale gas from the carburetor  
  • Unrivalled runtime made possible by the smart throttle technology
  • Noiseless operation means you don’t have to worry about noise in the background of your RV
  • Inverter generator with proprietary technology delivers stable electricity that’s ideal for the sensitive appliance. 
  • Oil watch system protects the generator from low oil level damage
  • Portable unit with wheels and handles for easy transportation


  • Lacks an electric start and it can be quite tricky starting the generator during the winter season
  • Its power output could be better

Why we choose this product

We see the petcock inclusion as one every RVer will come to appreciate. The 2800 watts rated power output of this generator didn’t turn our heads.

We liked the portability of the generator, but there’s something about the uneven wheels despite the parking brake that puts us off the unit.

The noise level is quite low, and we couldn’t have been more pleased. But its lack of an electric start is something we weren’t happy about.

What Size Generator do I need for 30 amps?

Before you settle for the generator size that can deliver on the 30 amps mandate, it’s crucial that you confirm the wattage of your electrical appliances, especially if you intend to use multiple appliances at the same time.

Always start with the most power-hungry appliance, such as the air conditioner or water heater. With those in the picture, you are confident on what’s left and how to make the most of it.

Buying Guide

 With the wattage outlay out of the way, you have to proceed on eggshells when settling for a generator through the factors relevant to making a buying decision.

Generator weight

This is often ignored by many RVers despite the need to move the generator between places. You are going to be lifting the generator or pushing them along, so you have to settle for a weight that’s not too heavy to cause any form of discomfort.

It’s also worth mentioning that the weight of a generator is actually directly proportional to its fuel consumption.

This means the more significant the size of the generator, the more fuel it will gobble over time, so keep that in mind when settling for an RV generator.


How long a generator will deliver on their power needs is something every camper doesn’t take for granted.

The runtime of a generator depends on a lot of things. One of such is its fuel efficiency.

The rate at which fuel is burnt to meet the power requirements of your RV appliances decides to a large extent the runtime of the generator.

Reduced fuel efficiency will decrease the runtime as more fuel is wasted since it’s not burnt efficiently.

There’s also the role played by the load (connected appliances) on the generator on its runtime. With more load on the generator, its runtime nosedives massively.

The engine type also affects the runtime of the generator. More powerful engines will use up more fuel, which translates to a shorter runtime.

Warranty coverage

While this isn’t an attribute of the best 30 amp generator, it tells you a lot about the durability of the unit.

If a manufacturer offers three years on its generator, it’s an indication of its confidence in its product. Anything lower, and they aren’t too sure of the integrity of their manufacturing process.

There’s also the issue of companies failing to meet the terms of their warranty while others appear to speak from both sides of their mouth on the nature of the offer.

Frequently Asked Questions

1. Will a 3500 watt generator run a 30 amp camper?

Of course, a generator with a power output of 3500 watts should be able to meet the demands of the 30 amp service of your camper. You can power most appliances in your rig with such an output.

2. Is a 4000 watt generator enough for RV?
