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 nutshell, the DuroMax XP8500E is a portable generator mostly geared towards:

  • Food truck owners who do not wish to see their business interrupted under any circumstances
  • 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, along with its emission compliance information.

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 7000W and a peak wattage of 8500W.

The generator features a simple traditional pull-start mechanism and also a simple and elegant electric starter (battery included). It is rated for a noise of 74 dBA (just slightly more noisy than a dishwasher).

The XP8500E can operate for around 10 hours at 50% load with a full tank (fuel consumption around 0.79 GPH), due to its fuel capacity of 7.9 gallons.

Since the XP8500E has a somewhat high THD (<12%), it is advisable to not use it for the powering of sensitive electronic devices.

Outlets

The control panel provides the upcoming 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 with which charging your batteries is made easy.

Due to the featured twist-lock L14-30R receptacle, the XP8500E is transfer switch ready: you may connect it to a breaker box to power your household during a power outage.

Portability

The DuroMax XP8500E has a conventional, open frame design, of the following dimensions: L30 x W30 x H26 in, which offers support and allows it to be raised above ground level. This type of design is ideal for tough environments and heavy outdoor use.

Since the generator weighs 200 lbs, it will be incredibly difficult to manually lift it and transport it, even though it is technically considered to 'be portable' (in the sense that it is movable). Still, once it is on the ground, its wheel kit and its folding handle can easily solve the issue of low mobility and allow for easy relocation of the device.

Features

The XP8500E's control panel

The control panel of the XP8500E includes a handy voltmeter that allows you to easily monitor power output anytime, helpful for the monitoring of its status and activity.

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

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

Along the basic documentation and an owner's manual (opens in a new tab), useful for starting the generator right away, the DuroMax XP8500E's package also includes these accessories: tool kit, battery charging cables and funnel. An official storage cover is also available, as a separate purchase.

Emissions

The DuroMax XP8500E is EPA-approved and CARB-compliant. Thus, selling and purchasing this generator is allowed in each of the 50 states, including California.

Moreover, it features a spark arrestor and thus, may be used in forested areas.

Product Video

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).

  • With a dry weight of 200 pounds, the DuroMax XP8500E finds itself in the expected weight range for generators able to produce between 6500 and 7500 rated watts. If weight matters to you, one of the champions in this power range is the Sportsman GEN85KIDF with only 133 pounds.
  • This generator has a somewhat average expected noise for its power range, rated at 74 dBA. For those who are looking for a less noisy device, we suggest the Powerhorse 7500i. With just 55 dBA, it is one of the most quiet devices in this power range.
  • The XP8500E, falls within the average autonomy range compared to generators of a roughly same power, with a run time of around 10 hours at a 50% load and a full tank. Concerning the run times, one of the several devices with a comparable output, offering the highest autonomy, is the Generac XC6500, which is able to run for around 14 hours.
  • Run times are important, yet thanks to their dependence on the fuel capacity, they should be judged along with the fuel consumption of the device. In fact, this generator is not among the most fuel efficient, within the aforementioned wattage range : its estimated gasoline consumption at 50% load is around 0.79 GPH. If you are concerned with gasoline efficiency, having a fuel consumption of just 0.38 GPH, the Lifan ESI 7000iER-EFI is a device you should look out for.

Price comparison

As you can see from this interactive chart, 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.
