Zoom on the Briggs & Stratton Q6500 QuietPower

In a nutshell, the Briggs & Stratton Q6500 QuietPower is a portable inverter generator mostly geared towards:

  • RV travellers wishing to enhance their freedom and nomad lifestyle
  • People occasionally participating in outdoor fairs, festivals or events
  • Food truck owners who do not wish to see their business interrupted under any circumstances
  • Homeowners who want to be able to use the most necessary devices in their household, even during a blackout
  • Tailgating and campground aficionados with the desire of enjoying power anywhere they go
  • Professionals in need of safely powering high-intensity work or lighting equipment

In the sections ahead, the power characteristics, availability of various outlets, the portability, and any additional features of the device shall be discussed, including its emission compliance information.

Power & Run Time

The Briggs & Stratton Q6500 QuietPower in use

The Briggs & Stratton Q6500 QuietPower

The Briggs & Stratton Q6500 QuietPower's design includes a gasoline-fueled 306 cc Briggs & Stratton OHV 4-stroke engine. With a 120/240V output, it gives a running wattage of 5000W and also a peak wattage of 6500W.

Enjoying a noise rating of 66 dBA (less noisy than a normal conversation), this inverter generator gets running thanks to a simple traditional pull-start mechanism.

The fuel capacity of 5 gallons allows the Q6500 QuietPower to operate for up to 14 hours with a full tank (fuel consumption around 0.36 GPH).

The Q6500 QuietPower generates a clean sine wave: providing <3% Total Harmonic Disruption (THD), delicate electronics can be plugged in its AC outlets safely.

Outlets

The control panel features the upcoming 5 AC outlets:

Two Duplexes 120V 20A (5-20R) GFCI
120/240V 30A (L14-30R) receptacle

In addition, it provides 2 DC outlets: there's two 5V USB ports with which charging of electronics like mobile phones and tablets is made convenient.

As the Q6500 QuietPower holds a twist-lock L14-30R receptacle, it is transfer switch ready: you'll easily be able to connect it to your breaker box to power your home during a power outage.

Portability

Since the Briggs & Stratton Q6500 QuietPower is an inverter generator, its closed design (L24.8 x W21.2 x H21.5 in) has an esthetical advantage over conventional, open frame devices. The design follows the contemporary trends and is perfect for recreationally generating power.

While the generator is considered to be technically 'portable' (in the sense that you can move it), manually lifting and transporting it may be challenging, due to its high weight of 139 lbs. Nevertheless, thanks to its set of 2 wheels (⌀8") and its telecospic handle (a decent solution to its lack of maneuverability), the generator can be easily moved, once placed the ground.

Features

Panel of the Briggs & Stratton Q6500 QuietPower

The Q6500 QuietPower's control panel

The Q6500 QuietPower's control center features power use LEDs that can both display the power output and the amount of hours the generator has accumulated to aid you with the monitoring of its status and activity.

In addition to this info, the light indicators show you if the generator is on overload, the generator is ready and its oil levels are insufficient.

The fuel level of the inverter generator can be determined quickly, easily, and conveniently with the help of its built-in fuel gauge.

The unit benefits from Briggs & Stratton’s Quiet Power Technology (QPT™), a feature designed to greatly improve its noise levels, emissions and fuel consumption. When the switch, located on the control panel, is turned ON, the engine speed increases as electrical loads are connected, and decreases as electrical loads are removed.

As far as security is concerned, the generator can be used with a peace of mind, as it features an automatic low oil shut-off and an overload protection (circuit breaker).

The Q6500 QuietPower also benefits from Briggs & Stratton’s CO Guard™ (opens in a new tab) carbon monoxide shutdown. This new patent-pending technology uses advanced algorithms to shut down the generator when harmful levels of carbon monoxide accumulate in the generator's operating area. It’s a welcomed additional security feature, but don’t forget to always take your generator outside (opens in a new tab).

With the basic documentation and an owner's manual (opens in a new tab), letting you start the generator quickly, the Briggs & Stratton Q6500 QuietPower also comes with several accessories, including: oil and funnel. An official storage cover is also available, as a separate purchase.

Emissions

The Briggs & Stratton Q6500 QuietPower is EPA approved, but NOT CARB-compliant. Thus, it cannot be purchased or sold in California.

However, it features a spark arrestor, making it usable in forested areas.

Product Videos

The Briggs & Stratton Q6500 QuietPower versus other generators

The following charts are provided to give you an idea of how some of the key specs of the Briggs & Stratton Q6500 QuietPower compare to generators of similar power (between 4500 and 5500 W).

  • In terms of its dry weight, the Briggs & Stratton Q6500 QuietPower stands at only 139 lbs, meaning that is one of the lighter devices of the 4500-5500 rated wattage category If weight matters to you, one of the champions in this power range is the WEN 56500 with only 119 pounds.
  • At a lowest noise rating of 66 dBA, this inverter generator is one of the quieter devices of similar power. If you’d prefer a less noisy device, one of the most quiet devices, which share the same power range with this one, is the Honda EU7000iS, whose lowest noise levels reach just 52 dBA.
  • Regarding its autonomy, the autonomy of the Q6500 QuietPower, reaching up to 14 hours at a 25% load, can be considered as low end, compared to other products of a roughly equal output. If autonomy is your priority, one of the devices of a similar power output with the highest run time is the Westinghouse WGen5300s, reaching up to 20 hours.
  • While the run time is an important parameter, it is dependent on the fuel tank’s capacity and thus, doesn’t say much on its own unless we consider fuel consumption as well. In fact, this inverter generator is not among the most fuel efficient, within the aforementioned wattage range : its estimated gasoline consumption at 25% load is around 0.36 GPH. If not satisfied with the afore-mentioned fuel consumption, you may wish to check out the Westinghouse WGen5300v. With a fuel consumption of as little as 0.24 GPH, it is one of the most efficient generators currently on the market.

Price comparison

As you can see from this interactive chart, when compared to other 4500-5500W generators, the Briggs & Stratton Q6500 QuietPower is on the average side of the price range.

Therefore, this generator nicely fits in the expected budget for this kind of product.

    Impressive performance. I had purchased the generator about 3 months before being hit by Hurricane Laura. It had not been used. I ran the generator continuously for 10 days and it ran flawlessly. Very fuel efficient consuming only 9 to 10 gallons of gas a day compared to similar wattage of my non-inverter generators that were consuming 16 to18 gallons per day.
    No major complaints. I Just wish that it was possible to run this unit in parallel with another 6500. I would then be set.

    + PROS:
    • Extremely fuel efficient
    • Low noise as good as competitors
    • Reliable
    • Starts easy
    • Excellent control panel
    • Heavy frame reduces vibration and improves stability
    - CONS:
    • No parallel port
    • No electric start
    • Inconvenient location of oil drain plug
