              Cons
              • No fuel meter
              • Wish the included funnel was sturdier

              The Briggs & Stratton Q6500 gives you the best compromise of compact size, lightness, and power – something that hardly finds on other generators at the same power range out there.

              It’s also built with two transporting wheels and a telescoping handle for extra maneuverability.

              The 306cc engine is integrated with advanced inverter technology, making its runtime a lot longer, up to 14 hours at 25% runtime (while most of its competitors are averagely around 7-8.5 hours).

              It doesn’t produce much noise during operation, thanks to the all-steel frame enclosed frame.

              But what we appreciate the most is the added CO Guard – a special sensor used for detecting levels of carbon monoxide, and once the levels are under the safety standard, it will automatically shut the generator off for safety.

              How To Choose The Quietest Generator for RV?

              Engine Types

              Inverter engines

              One of the most effective ways to lower the operation noise of RV generators is to go for ones with an inverter engine.

              Unlike the regular generators, this new engine type uses advanced technology in producing power, which leads to a huge reduction in operation noise.

              Its smaller engine size as well as the capability of adjusting the energy output to the load at different times also make it work more smoothly and quietly.

              Not to say that inverter engines produce cleaner power to run more vulnerable electronics, such as smartphones, tablets, and laptops. They’re very lightweight as well.

              Conventional engines

              As stated above, conventional engines work more loudly and they only work at the same speed, meaning that it is noisy all the time.

              In turn, this generator engine type is very budget-friendly.

              If you want to buy a conventional engine generator and want it to be quieter during operation, consider these additional features:

              • Muffler
              • Baffle box
              • Acoustic enclosure
              • Any kind of sound defectors
              • Rubber feet

              Choose The Right Generator Size

              Talking about the correlation between generators’ power and noise, a fact is that the higher the power output, the more noisily the machine works.

              Therefore, it’s important to choose the right generator size for your power needs. Don’t go for a too big one because it’s also wasteful in power use.

              To choose the right generator size, you should determine the number of RV essentials needed charging/running at the same time, then, calculate the total amount of wattage required.

              Which Brands Make The Quietest Generator for RV?

              Generac

              Generac is one of the biggest and longest-standing manufacturers of power generation products in the USA. They have over 6,500 employees and four huge facilities in Wisconsin.

              More importantly, they were given the Natural Gas Generator Company of the Year Award in 2014 by Frost & Sullivan. Some of their portable generators have also earned the Good Housekeeping Seal.

              Westinghouse

              Started in 1886 in the US, Westinghouse is the leading company in the fields of high-voltage alternating-current transmission, power transmission. They own over 28,000 U.S. government patents during the 20th century.

              Briggs & Stratton

              Founded in 1908 by Harold M. Stratton and Stephen Foster Briggs, it is one of the three biggest US manufacturers dedicated to power generation equipment and is the leader in gasoline engine production. They are honored to be on the American Fortune 1000 list.

              FAQs

              How loud can a generator be in a campground?

              A generator’s noise level should not exceed 60dB if used in a campground.

              What size generator do I need for RVs?

              For RV use, we highly recommend using a 2000W-4000W generator.

              Is it OK to run an RV generator all night?

              Yes, it is. Make sure that your RV generator is built with all required safety features.

              What does 52 dB sound like?

              52dB sounds like a running refrigerator, hairdryer, electric fan, or a quiet street.

              Can an RV generator run while driving?

              Yes, it can. All the RV generators are designed to stay in place and be connected directly to the RV, therefore, while you’re driving, it is still able to work.

              Conclusion

              In a nutshell, we hope that our hard work benefits you in determining the quietest generator for RV for your needs, budget, and preference.
