The Champion generator has earned the top spot on our list, and for very good reason - it has an outstanding reputation as one of the quietest propane generators on the market, and sound levels come in at a whisper-quiet 58 dBA, making it perfect even in residential or crowded areas - there will be no need to worry about your neighbors complaining.

The quiet operation also allows you to use the generator on camping sites, or on your RV, without worrying about disturbing others.

Longevity is another major advantage to this generator; you can enjoy 7.5 hours of run time and 3100 watts with a full tank of gasoline, or 14.5 hours if you use a 20lb propane tank - and both are on hand in the event that you need extra power.

The inclusion of dual-fuel offers freedom and flexibility, and you can also connect to another champion inverter for added convenience. Choose from one of three positions in the electric start for seamless use, and allow the economy mode to automatically detect the amount of energy required.

The generator will then slow the amount of energy, and the end result will be quieter, more productive, and more effective.

As well as being super-efficient, the generator is also extremely easy to use thanks to a quick touch panel, a battery, and a smart charger, keeping your battery powered up and ready to go at a moment's notice.

Quietest Propane Generator Buying Guide

Now that we have taken a look at some very quiet propane generators on the market, it is time to take a closer look at what makes these the best of the best.

There are a few elements to consider, and we will explore these below.


The power output of a particular generator will play a large role in your decision, and will likely be one of the deciding factors. In short, the power output of a generator determines just how many appliances you will be able to use.

You need to do your homework ahead of your purchase, in order to determine your power requirements - the last thing you want is to get home and discover that your generator is not powerful enough for your needs, or, worse still, to get to a campsite and find yourself without power.

Make sure you have an idea of the number of watts each of the items you wish to power require - you will find this information on the equipment itself - and then make sure that the generator you choose can handle this demand.

Every generator you look at will be sold based on power rating, and you need to focus not only on the maximum capacity but also the continuous running power. You should also check to see the power output of the device when you use propane as fuel - this can be lower than if you use gasoline or dual fuel.

Noise Level

Another obvious consideration is the noise level emitted by your generator - this is one of the most important aspects to take into account in order to ensure happy neighbors, and a calm, peaceful environment.

Even the quietest propane generator will still make some noise. Most of the options we have selected will operate at around 50 to 65 dBA, with some going below this.

It is a good idea to go as low as you can in terms of the noise generated - this will help to keep everyone happy! For a general idea of how loud your quiet generator is, here are some points of comparison:

  • A whisper is 30 dBA
  • Moderated rainfall is 50 dBA
  • Most normal conversations are 60 dBA
  • City traffic is 70 dBA
  • Hairdryers are 80 dBA
  • A jet plane taking off is 120 dBA

Another consideration is whether a muffler would be a useful addition to your equipment - this can help to reduce the noise level on some generators, though their results tend to vary.

Some models may even come with a muffler included to reduce the sound, even more, so make sure that you check these out if this is important to you.

Another option is to construct some form of DIY generator quiet box enclosure around your generator while it is in operation, though this is less practical if you need to transport your equipment from place to place.

Type of Generator

Not all generators are created equal, and the best fit for your needs will depend largely on what you are planning to use it for, and where you need it to work.

Consider whether you will be spending most of your time on a campsite, in the back of an RV, or whether this is intended as a backup generator for your home. Ultimately, your needs will determine the type of generator you opt for, so think carefully.


Portability is another very important consideration and one which is likely to play a large part in your decision.

Once again, this depends largely on your intended usage - if you need the generator to take care of you across multiple sites, such as for camping trips, or use on an RV, then portability will be a far higher priority than those who are simply seeking a backup generator for their existing home.

Even in this case, however, you will still want something that you can lift and move with relative ease.

Potential Run Time

Take a moment to check out the length of time your generator will run for - this will tell you roughly the amount of propane you will need to use and budget for.

A generator that runs more slowly will require less fuel, while those which are faster come with a downside - they need more fuel. As a general rule, most propane generators run a little more slowly, and this allows them to operate more quietly.


Ultimately, you can only spend what you can afford, and so having a clear budget in mind is very important.

While cheaper generators may seem more tempting in the short term, always consider the long-term potential - will this stand the test of time, or will you need to be investing in a new generator in just a few years?

It is a good idea to look for quality and buy the quietest propane generator you can afford, as this can save you money in the long term.

Parallel Output

Parallel output is another feature that is well worth including in your chosen selection - this allows you to connect two generators together to increase the total potential output available - ideal if you know someone with a similar generator and need to increase your capacity.

By making sure that the product you buy has this included, you are future-proofing your generator, and ensuring that it will have enough power for all your needs for many years to come.


Another feature that is all too often overlooked is ensuring that your generator is compliant with standards set out by the United States Environmental Protection Agency (EPA), and the California Air Resources Board (CARB).

Make sure that the generator you purchase has a certificate of compliance from these agencies. While propane is increasingly common and popular due to its eco-friendly nature and reduced noise, this is always worth double-checking.
