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 want to ensure that their business is fully self-contained and does not rely on potentially unreliable external power
  • Professionals in need of safely powering high-intensity work or lighting equipment

In the sections ahead, the power characteristics, availability of various outlets, the portability, and any additional features of the device shall be discussed, including its emission compliance information.

Power & Run Time

The DuroMax XP8500E houses a 420 cc (16 hp) DuroMax OHV 4-stroke engine, which provides 120/240V, consumes gasoline and delivers a running wattage of 7000W along with a peak wattage of 8500W.

With a noise rating of 74 dBA (just slightly more noisy than a vacuum cleaner), the generator features a simple traditional pull-start mechanism, but also a simple and elegant electric starter (battery included).

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.

The powering of sensitive electronic devices with the XP8500E is not recommended due to its relatively high THD (<12%).

Outlets

The control panel provides the upcoming 5 AC outlets:

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

It also sports 1 DC outlet: there's a 12V 8A output with which charging your batteries is made easy.

Because the XP8500E is equipped with a twist-lock L14-30R receptacle, it is transfer switch ready: it can power your home during a power outage, as it can be easily connected to your breaker box to power your household.

Portability

The DuroMax XP8500E has the following dimensions: L30 x W30 x H26 in. In combination with its conventional, open frame design, they provide support and allow the generator to be raised above ground level. The design is ideal for rough environments and demanding outdoor use.

As the generator's weight is 200 pounds, manually moving it or transporting it may be challenging, despite the fact that it is technically considered 'portable' (movable). However, this lack of maneuverability is compensated by its wheel kit and its folding handle, with which you can conveniently shift it, once it's on the ground.

Features

Panel of the DuroMax XP8500E

The XP8500E's control panel

The XP8500E's control center features a convenient voltmeter, which provides an easy way to monitor power output anytime to aid you with the monitoring of its status and activity.

A built-in fuel gauge allows for a quick, easy and convenient check of the fuel level of the generator.

Security-wise, this product benefits from an automatic low oil shut-off and an overload protection (circuit breaker), which gives you a complete peace of mind when using it.

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: tool kit, funnel and battery charging cables. An official storage cover is also available, as a separate purchase.

Emissions

The DuroMax XP8500E is EPA-approved and CARB-compliant. It can therefore be sold and purchased in all 50 states, including California.

Moreover, it features a spark arrestor and therefore, can 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).

  • Having a dry weight of 200 lbs, the DuroMax XP8500E belongs in the expected weight range for generators which produce 6500 to 7500 rated watts. If weight is your top priority, one of the champions in this power category is the Sportsman GEN85KIDF, weighing just 133 pounds.
  • The generator can be considered average in its noise for its power category, as it is rated at 74 dBA. If noise emissions are one of your priorities, you may be interested in the Powerhorse 7500i, one of the least noisy generators similarly powerful as this one, rated for 55 dBA.
  • 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. Furthermore, considering the run times, one of the generators which have a roughly same power output, with the highest autonomy, is the Generac XC6500, as it provides around 14 hours.
  • While the run time is an important parameter, it is dependent on the fuel tank’s capacity and thus, doesn’t say much on its own unless we consider fuel consumption as well. This generator is somewhat less fuel efficient than devices of comparable output: its estimated fuel consumption reaches 0.79 GPH at a 50% load. 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.

The bottom line
