              • Fuel-efficient & long runtime – inverter technology + an auto-idle feature
              • Safe and quiet - CARB compliant & feature overload protection fuel tank, muffler, and low oil shutdown
              Cons
              • No transportation wheels
              • Poor directions

              This propane generator is very fuel-efficient because 1) it is an inverter type and 2) it’s built with an auto-idle feature. For those who are new to this feature, it helps save fuel when less power is required to hence extend the total runtime.

              On a full 20-pound tank running at ¼ load, it can last up to 60 hours.

              Regardless, feel peace in mind when using this propane generator because it’s under a manufacturer’s 2-year limited warranty. The device itself is CARB compliant.

              We also love it for safety and quiet operation, which is a big thank you to the overload protection fuel tank, muffler, and low oil shutdown.

              Pros
              • Fuel efficient – the Eco Mode and idle control
              • Able to double the power output if wanted - parallel compatibility
              • Easy to carry around – lightweight & a handle
              Cons
              • No transportation wheels
              • The parallel kit is sold separately

              While all inverter generators are fuel-efficient, we find the DuroMax XP2000EH makes it to the next level. It emphasizes an Eco Mode for lowering its idle speed to the minimum propane consumption.

              In addition to that, it has idle control to lower its RPMs when less power is required, and as the result, it lasts up to 6.5 hours at ½ load.

              Another big bonus is its parallel compatibility, which allows for bridging two XP2000EH generators at a time for higher power output.

              You might see that this unit doesn’t have transportation wheels (which is a pity!), in turn, it highlights a handle and the total weight is only 47 pounds. It’s easy to lift up and carry around – perfect for camping, tailgating, or emergency power.

              How To Choose The Best Quiet Propane Generator?

              Noise level

              When you’re seeking a quiet generator, the noise level should always be the highest priority. The noise level is measured in dB, the higher the value, the nosier the machine.

              There isn’t a generator that’s completely quiet, but you can find a machine that makes noise lower than the conversational level. As a rule of thumb, a noise rating between 55 and 65 dBA is considered quiet for a propane generator.

              Power output

              No matter how quiet a generator is, you still need enough output power to run your tools and appliances. The more power produced, the more appliances you can run.

              However, you need to first figure out how much power you need by taking into account the essential tools and appliances to use. Then, when shopping, you just have to find the power you need or higher.

              For example, a generator as a home backup power source should produce about 8000W to run appliances for a good amount of time.

              Runtime

              The runtime refers to the duration that a generator can run on a certain amount of fuel, often measured at 25 or 50 percent of the load. A generator with a low runtime tends to consume less fuel, but you should look at this indicator on the machine and choose the one that fits your needs.

              Which Brands Make The Best Quiet Propane Generator?

              Champion

              FAQs

              Are propane generators any good?

              Yes, propane generators are cleaner and quieter than gas generators. And though they are generally less powerful, you can still find models that produce enough energy for your demand.

              What are the disadvantages of propane?

              The following are the drawbacks of propane:

              • It’s not as popular as gasoline or diesel.
              • It has a lower energy density than gasoline and diesel.
              • Propane is also sensitive and won’t work in low temperatures.
              • It’s highly flammable.

              How long will a generator run on a 20lb tank of propane?

              A propane generator with a 20lb tank can work for 8 hours.

              How long does a generator last on propane?

              In general, a generator can last from 1,000 to 2,000 hours of operation, meaning 10-20 years. And considering that propane is a clean-burning fuel, the machine requires lower maintenance and can last longer.

              Is it cheaper to run a generator on propane or gas?

              Typically, running a gas generator is cheaper than running a propane one, unless you live in a place where propane costs much less than gasoline.

              Conclusion

              We hope that through this complete guide, you have figured out what to look for in the best quiet propane generators that meet your needs.

              Remember that noise level should be the first thing to look at and you cannot compromise it if you really want quietness. If you have more questions or need guides on other products, don’t hesitate to come back here.
