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 sporting competitions, open-air performances and outdoor festivals
  • Food truck owners who do not wish to see their business interrupted under any circumstances
  • Homeowners who want to be sure of their ability to power their fridges, cooking tools, heating and lighting equipment during power failures
  • Camping and tailgating hobbyists looking for a portable power source
  • Professionals who want to ensure that a power failure will not prevent them from working

In the following paragraphs, we shall explore the power characteristics, available outlets, portability, and any additional features of the device, along with 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 5,000W and also a peak wattage of 6,500W.

The inverter generator is rated for a noise of 66 dBA (less noisy than an office). Its starting mechanism is based on a conventional pull-start mechanism.

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

As the Q6500 QuietPower produces a clean sine wave, with a <3% Total Harmonic Distortion (THD), sensitive electronics may be plugged in the AC outlets safely.

Outlets

The control panel features the following 5 AC outlets:

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

It also sports 2 DC outlets: there's two 5V USB ports allowing you to conveniently charge electronics such as mobile phones and tablets.

As it features a twist-lock L14-30R receptacle, the Q6500 QuietPower is transfer switch ready: in case of a power outage, you will be easily able to connect it to a breaker box and power your household.

Portability

As the Briggs & Stratton Q6500 QuietPower is an inverter generator, its encased design (L24.8 x W21.2 x H21.5 in) offers more aesthetics than a conventional, open frame product. The generator has a contemporary design, convenient 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

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, the device’s light indicators will display if the oil level is too low, the generator is overloaded and the generator is ready.

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.

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: 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, which makes it suitable for use in forested areas.

In addition, the unit meets the ANSI/PGMA G300-2018 safety and performance requirements.

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).

  • Regarding its weight, the Briggs & Stratton Q6500 QuietPower only weighs in at 139 pounds, which means it's one of the lighter generators in the 4500-5500 rated wattage range. If weight is your top priority, one of the champions in this power category is the WEN GN5600, weighing just 103.6 pounds.
  • The inverter generator can be considered average in its noise for its power category, as it is rated at 66 dBA. 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.
  • Autonomy-wise, with up to 14 hours on a full tank at a 25% load, the Q6500 QuietPower is on the low end when compared to other generators of a similar power output. If you consider autonomy on a single full tank as one of the deciding factors, one of the generators in the same power range that offers the highest run time is the DuroMax XP5500EH, with up to 19 hours.
  • Even though run times are undoubtedly important, they are dependent on the fuel capacity to a large extent. For a more wholesome picture, we must take into consideration the fuel consumption of the generator. This inverter generator is somewhat less fuel efficient than devices of comparable output: its estimated fuel consumption reaches 0.36 GPH at a 25% load. If not satisfied with the afore-mentioned fuel consumption, you may wish to check out the DuroMax XP5500EH. With a fuel consumption of as little as 0.21 GPH, it is one of the most efficient generators currently on the market.

Price comparison

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

It can therefore be a really good buy if you're looking to acquire a budget generator.

    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
