Description

Designed to give you quiet confidence during power outages, the Q6500 QuietPower™ Series inverter generator is more than 60% quieter than standard generators and can deliver 6,500 starting watts of reliable backup power. (source: Briggs & Stratton (opens in a new tab))

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
  • Camping and tailgating buffs looking to enhance their experience
  • Professionals who want to ensure that a power failure will not prevent them from working

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.

With a noise rating of 66 dBA (less noisy than background music), the inverter generator features a simple traditional pull-start mechanism.

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

The Q6500 QuietPower produces a clean sine wave: thanks to a <3% Total Harmonic Disruption (THD), your sensitive electronics can be safely plugged in the AC outlets.

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 you may charge electronics, for example mobile phones or tablets, conveniently.

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

The Briggs & Stratton Q6500 QuietPower is an inverter generator and has an encased design of the following dimensions: L24.8 x W21.2 x H21.5 in. Thus, it is more aesthetical than conventional, open frame products. This type of design is the most modern and convenient way to recreationally generate power.

Although this generator is technically considered 'portable' (in the sense that it can be moved), its 139 lbs make it incredibly difficult to manually lift and transport. Nevertheless, it can still be moved quite conveniently with the help of its set of 2 wheels (⌀8") and its telecospic handle, once it is placed on the ground.

Features

Panel of the Briggs & Stratton Q6500 QuietPower

The Q6500 QuietPower's control panel

To help you monitor the Q6500 QuietPower's status and activity, its control panel is equipped with power use LEDs that can both display the power output and the amount of hours the generator has accumulated.

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

The inverter generator includes a built-in fuel gauge, a quick, easy and convenient method of checking the device’s gas level.

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 overload protection (circuit breaker) and an automatic low oil shut-off.

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).

Along the basic documentation and an owner's manual (opens in a new tab), useful for starting the generator right away, the Briggs & Stratton Q6500 QuietPower's package also includes these accessories: funnel and oil. 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 and therefore, can be used 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).

  • As far as its dry weight is concerned, the Briggs & Stratton Q6500 QuietPower weighs just 139 pounds and thus, it is one of the lighter 4500 to 5500 rated wattage generators. Regarding dry weight, one of the champions in the same power range is the WEN GN6000, with a dry weight of only 119 lbs.
  • At a lowest noise rating of 66 dBA, this inverter generator is one of the quieter devices of similar power. If noise emissions are important to you, one of the least noisy generators of this power range is the Honda EU7000iS with only 52 dBA.
  • As far as autonomy is concerned, providing up to 14 hours of runtime with a full tank at a 25% load, the Q6500 QuietPower falls into the low end in comparison with other devices of a comparable power output. Concerning the run times, one of the several devices with a comparable output, offering the highest autonomy, is the Westinghouse WGen5300DFv, which is able to run for up to 20 hours.
  • The run time is important, but also hugely depends on the capacity of the fuel tank and doesn't mean much if we don't talk about fuel consumption as well. Compared to its peers, this inverter generator is not exactly fuel efficient, compared to similarly powerful devices, with an estimated fuel consumption of 0.36 GPH at a 25% load. If you are concerned with gasoline efficiency, having a fuel consumption of just 0.24 GPH, the Westinghouse WGen5300DFv is a device you should look out for.

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
