Zoom on the Briggs & Stratton Q6500 QuietPower
To sum up, the Briggs & Stratton Q6500 QuietPower is a portable inverter generator tailored for:
- RV travellers wishing to enhance their freedom and nomad lifestyle
- People occasionally participating in sporting competitions, open-air performances and outdoor festivals
- Food van owners who know that just a short power outage could lose them hundreds of dollars
- Homeowners who want to be sure of their ability to power their fridges, cooking tools, heating and lighting equipment during power failures
- Professionals who want to be able to deliver results, even during a power failure
The following sections will present you in detail its power characteristics, the different outlets it offers, its overall portability, and the extra features it benefits from.
Power & Run Time
Briggs & Stratton Q6500 QuietPower runs on gasoline, powered by a 306 cc Briggs & Stratton OHV 4-stroke engine, delivering 120/240V, boasting a running wattage of 5,000W alongside a starting wattage of 6,500W.
At a noise rating of 66 dBA (less noisy than an office), the inverter generator is started via a conventional pull-start mechanism.
With its 5 gallons fuel tank, the Q6500 QuietPower can operate for up to 14 hours when fully fueled (with fuel usage averaging around 0.36 GPH).
Sensitive electronics can be safely plugged in the AC outlets, as the Q6500 QuietPower produces a clean sine wave, with a <3% Total Harmonic Distortion (THD).
Outlets
The control panel is equipped with the following 5 AC outlets:
Additionally, it features 2 DC outlets: there's two 5V USB ports with which you may charge electronics, for example mobile phones or tablets, conveniently.
With its twist-lock L14-30R receptacle, the Q6500 QuietPower is configured to be transfer switch ready, allowing straightforward connection to your breaker box to supply backup power to your home during outages.
Portability
As an inverter generator, the Briggs & Stratton Q6500 QuietPower showcases a closed design (L24.8 x W21.2 x H21.5 in), enhancing aesthetics and ensuring quieter operation compared to conventional, open frame models. The design follows the contemporary trends and is perfect for recreationally generating power.
Despite its weight of 139 lbs, the generator is still considered 'portable,' meaning it is movable, although its heftiness may restrict portability in certain environments or require additional considerations for transportation and setup. Still, once it is on the ground, its set of 2 wheels (⌀8") and its telescopic handle can easily solve the issue of low mobility and allow for easy relocation of the device.
Features
To facilitate status and activity monitoring, power use LEDs that can both display the power output and the amount of hours the generator has accumulated are embedded in the control panel of the Q6500 QuietPower.
In addition to this info, several light indicators serve to show you when the generator is ready, the generator is overloaded and the oil level is too low.
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.
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: oil and funnel. An official storage cover is also available, as a separate purchase.

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 inverter generators of similar power (between 4500 and 5500 W).
- At a weight of 139 pounds, the Briggs & Stratton Q6500 QuietPower places in the expected weight range of the inverter generators in the 4500-5500 rated wattage range. If weight matters to you, one of the champions in this power range is the Pulsar PGX60BiSRCO with only 93.5 pounds.
- With noise emissions rated as low as 66 dBA, this inverter generator falls within the typical noise range expected for devices of similar type and power. If you'd like a less noisy alternative, the Honda EU7000iS is a strong contender. It boasts a noise rating of 52 dBA, placing it among the quietest generators in its power category.
- In terms of its autonomy, the Q6500 QuietPower can operate for up to 14 hours at a 25% load, placing it within the lower bracket among generators of similar type and power range. If autonomy is your priority, one of the devices of a similar power output with the highest run time is the Champion 201535, reaching up to 18 hours.
- Autonomy holds its importance, however, it is largely dependent on the generator’s fuel capacity and so, it is nonsensible to discuss it without mentioning fuel efficiency as well. 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. To prioritize fuel savings, we advise considering the DuroMax XP7000iHT, which stands out for its gasoline efficiency, consuming just 0.19 gallons per hour.
Here's a list of the most popular specific comparisons:
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 average side of the price range.
Therefore, this generator nicely fits in the expected budget for this kind of product.

User Reviews
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.
