Description

The DuroMax XP8500E unit features a 16 Horsepower, Air Cooled Engine and is designed with a Low-Oil Shutoff Sensor to protect the Motor. A newly added feature is the Idle Control (referred to as Auto Throttle) which enable the motor to maintain RPM's under varying loads. This help maximizes fuel efficiency while minimizing the noise output. Built to offer more power and longer lasting durability. (source: DuroMax (opens in a new tab))

Zoom on the DuroMax XP8500E

In a few words, the DuroMax XP8500E is a portable generator perfectly suited for:

  • Food van owners who know that just a short power outage could lose them hundreds of dollars
  • Homeowners who want to be able to use the most necessary devices in their household, even during a blackout
  • Professionals who want to ensure that a power failure will not prevent them from working

In the forthcoming sections, you'll delve into its power characteristics, the various outlets it offers, its overall portability, and the additional features it boasts.

Power & Run Time

The DuroMax XP8500E's core is the 420 cc (16 hp) DuroMax OHV 4-stroke engine, which runs on gasoline. With an output of 120/240V, it provides a running wattage of 7,000W and a peak wattage of 8,500W.

The generator features a traditional recoil pull-start mechanism and also a convenient and efficient electric starter (battery included). It is rated for a noise of 72 dBA (just slightly more noisy than a dishwasher).

The XP8500E's fuel tank, with a capacity of 7.9 gallons, supports uninterrupted operation for up to 25 hours when fully fueled (fuel consumption at an estimated 0.32 gallons per hour).

The quite high THD (<12%) of the XP8500E makes it unsuitable for powering sensitive electronic devices.

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

Additionally, it features 1 DC outlet: there's a 12V 8A output allowing you to easily charge your batteries.

With its twist-lock L14-30R receptacle, the XP8500E is configured to be transfer switch ready, allowing straightforward connection to your breaker box to supply backup power to your home during outages.

Portability

At L30 x W30 x H26 in, the traditional open frame structure of the DuroMax XP8500E ensures stability while facilitating convenient maintenance access to components and promoting air cooling. The design is ideal for rough environments and demanding outdoor use.

Although this generator is technically considered 'portable' (in the sense that it can be moved), its 200 lbs make it incredibly difficult to manually lift and transport. Nevertheless, the restricted maneuverability is counteracted by its wheel kit (⌀10") and its folding handle, enabling easy shifting once the generator is set in place.

Features

Panel of the DuroMax XP8500E

The XP8500E's control panel

To facilitate status and activity monitoring, a convenient voltmeter, which provides an easy way to monitor power output anytime are embedded in the control panel of the XP8500E.

The inclusion of a built-in fuel gauge in the generator streamlines gas level checks for quick and convenient assessments.

From a security standpoint, the product offers an automatic low oil shut-off and an overload protection (circuit breaker), allowing you to use it with a peace of mind.

While the standard documentation and an owner's manual (opens in a new tab), helpful for starting the device promptly, come with the DuroMax XP8500E, the following accessories are also included: battery charging cables, tool kit and funnel. An official storage cover is also available, as a separate purchase.

The DuroMax XP8500E versus other generators

The following charts are provided to give you an idea of how some of the key specs of the DuroMax XP8500E compare to generators of similar power (between 6500 and 7500 W).

  • Since the generator weighs in at a dry weight of 200 lbs, the DuroMax XP8500E belongs in the expected weight range for devices which can produce between 6500 and 7500 rated watts. If you are concerned by weight, one of the champions in the above-mentioned power range is the Sportsman GEN85KIDF, with a dry weight of just 133 pounds.
  • Because this generator emits noise as low as 72 dBA, it can be considered to have a pretty average expected noise rating for a device of its power. If you wish to prioritize minimal noise, the Powerhorse 7500i stands out as one of the quietest options among generators of similar power, with a rating of 55 dBA.
  • Among its devices with similar power, the XP8500E offers one of the highest run times, running for up to 25 hours at 25% load.
  • While run time matters, it's heavily influenced by the fuel tank's capacity. Hence, it's important to consider fuel efficiency alongside. This generator, with an estimated fuel consumption of just 0.32 GPH (gallon per hour) at 25% load, is one of the more fuel-efficient generators, for the previously mentioned wattage range. If you are concerned with gasoline efficiency, having a fuel consumption of just 0.29 GPH, the DuroMax XP7500DX is a device you could look out for.

Price comparison

As you can see from these interactive charts, when compared to other 6500-7500W generators, the DuroMax XP8500E is on the average side of the price range.

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

Is this a quiet generator or is it loud? (Asked July 23, 2023)

The unit sound level is rated at 72dB at low load, and at 23 feet. It is not quiet by any means, but what is to be expected for a conventional open frame generator of this power. If noise is an important factor to you, you may want to consider an inverter generator.
