Zoom on the Briggs & Stratton Q6500 QuietPower

In short, the Briggs & Stratton Q6500 QuietPower is a portable inverter generator adequately designed for:

  • RV travellers who wish to upgrade their experience to another level
  • Occasional participants of outdoor events, competitions, concerts and festivals
  • Food truck owners who want to ensure that their business is fully self-contained and does not rely on potentially unreliable external power
  • 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 who want to be able to deliver results, even during a power failure

In the following paragraphs, we shall explore the power characteristics, available outlets, portability, and any additional features of the device.

Power & Run Time

The Briggs & Stratton Q6500 QuietPower in use

The Briggs & Stratton Q6500 QuietPower

Running on gasoline, the Briggs & Stratton Q6500 QuietPower utilizes a 306 cc Briggs & Stratton OHV 4-stroke engine to deliver 120/240V, offering a running wattage of 5,000W and a starting wattage of 6,500W.

The inverter generator features a classic hand-operated recoil starting mechanism. It is rated for a noise of 66 dBA (less noisy than background music).

The Q6500 QuietPower's fuel tank, boasting 5 gallons, allows it to operate for up to 14 hours with a full tank (with an estimated fuel consumption of 0.36 GPH).

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

Outlets

The control panel is equipped with the following 5 AC outlets:

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

Furthermore, it has 2 DC outlets: there's two 5V USB ports perfect for conveniently charging mobile phones, tablets, and other electronic devices.

Equipped with a twist-lock L14-30R receptacle, the Q6500 QuietPower is engineered to be transfer switch ready, enabling simple hookup to your breaker box to provide backup power for your home during blackouts.

Portability

With an inverter generator design, the Briggs & Stratton Q6500 QuietPower features a closed construction (L24.8 x W21.2 x H21.5 in), enhancing aesthetics and ensuring reduced noise levels, offering a distinct advantage over standard, open frame generators. This modern design aims to provide an ideal power solution to recreational users.

As the generator's weight is 139 pounds, manually moving it or transporting it may be challenging, despite the fact that it is technically considered 'portable' (movable). 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

The Q6500 QuietPower's control panel

The Q6500 QuietPower's status and activity may be monitored conveniently via the control panel, as it features power use LEDs that can both display the power output and the amount of hours the generator has accumulated.

In addition to this info, light indicators on the device will signal if the generator is ready, the generator is on overload and the oil level is too low.

The built-in fuel gauge of the inverter generator ensures simple and quick gas level assessments.

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.

From a security standpoint, the generator is furnished with an automatic low oil shut-off and an overload protection (circuit breaker), ensuring peace of mind during operation.

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.

Alongside the standard documentation and an owner's manual (opens in a new tab) for quick setup, the Briggs & Stratton Q6500 QuietPower is bundled with additional accessories: funnel and oil. An official storage cover is also available, as a separate purchase.

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).

  • Weight-wise, the Briggs & Stratton Q6500 QuietPower has only 139 lbs, which renders it one of the lighter generators which produce 4500 to 5500 rated watts. If weight is your top priority, one of the champions in this power category is the Champion 201238, weighing just 101.4 pounds.
  • This inverter generator has a somewhat average expected noise for its power range, rated at 66 dBA. If noise level is one your key decisive factors, you may find the Honda EU7000iS appealing. It's rated at 52 dBA, making it one of the quietest generators in its power range.
  • Regarding its autonomy, the Q6500 QuietPower can run for up to 14 hours at a 25% load, aligning it with the lower performers in its power range. Concerning the run times, one of the several devices with a comparable output, offering the highest autonomy, is the DuroMax XP5500EH, which is able to run for up to 19 hours.
  • While run time is vital, it hinges on the fuel capacity. To grasp the full picture, we must also factor in fuel efficiency. 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 you wish to get a unit of similar power, but with one of the best fuel efficiency, you could consider the DuroMax XP7000iH, which has an impressively low fuel consumption of 0.19 GPH.

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
