Description

Be ready for anything with the DuroMax XP8500EH generator. Equipped to run on either gasoline or liquid propane, this dual fuel unit can perform anywhere that portable power is needed. Easy to transport over any terrain, the XP8500EH generator will keep you going. (source: DuroMax (opens in a new tab))

Zoom on the DuroMax XP8500EH

In summary, the DuroMax XP8500EH is a portable generator especially useful for:

  • Food truck owners who want to ensure that their business is fully self-contained and does not rely on potentially unreliable external power
  • Professionals who want to be able to deliver results, even during a power failure

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

Thanks to its dual-fuel technology, the DuroMax XP8500EH delivers 120/240V and offers power and versatility. When gasoline-powered, it benefits from a running wattage of 7000W and a peak wattage of 8500W. When propane-powered, it has 6650 rated watts and 8075 peak watts.

Enjoying a noise rating of 72 dBA (just slightly more noisy than a dishwasher), this generator can be started thanks to a simple traditional pull-start mechanism, but also to a simple and elegant electric starter (battery included).

With a fuel capacity of 7.9 gallons, the XP8500EH can operate for around 10 hours at 50% load using gasoline (fuel consumption around 0.79 GPH), or for around 5 hours (on a 20 lbs tank - propane consumption around 0.94 GPH) using propane.

Outlets

The control panel includes the following 5 AC outlets:

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

In addition, it provides 3 DC outlets: there's a 12V 8A output with which charging your batteries is made easy and two 5V USB ports with which you may charge electronics, for example mobile phones or tablets, conveniently.

Since the XP8500EH bears a twist-lock L14-30R receptacle, it is transfer switch ready: it is easily connectible to a breaker box and can power your home in case of a power outage.

Portability

With its dimensions of L30 x W30 x H26 in, the conventional, open frame design of the DuroMax XP8500EH offers stability and allows the generator to be raised above ground level. The device has been designed for tough environments and demanding outdoor use.

While the generator is considered to be technically 'portable' (in the sense that you can move it), manually lifting and transporting it may be challenging, due to its high weight of 204 lbs. Nevertheless, thanks to its wheel kit and its folding handle (a decent solution to its lack of maneuverability), the generator can be easily moved, once placed the ground.

Features

Panel of the DuroMax XP8500EH

The XP8500EH's control panel

The control panel of the XP8500EH includes a convenient meter showing you voltage, frequency and lifetime hours, helpful for the monitoring of its status and activity.

The fuel level of the generator can be determined quickly, easily, and conveniently with the help of its built-in fuel gauge.

As for its security measures, the device features an overload protection (circuit breaker) and an automatic low oil shut-off, letting you 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 XP8500EH's package also includes these accessories: battery charging cables, propane hose, funnel and tool kit. An official storage cover is also available, as a separate purchase.

Emissions

The DuroMax XP8500EH is EPA-approved and CARB-compliant. Therefore, its sale and purchase are permitted in all of the 50 states, including California.

Moreover, it features a spark arrestor, making it usable in forested areas.

The DuroMax XP8500EH versus other generators

The following charts are provided to give you an idea of how some of the key specs of the DuroMax XP8500EH compare to generators of similar power (between 6500 and 7500 W).

  • Having a dry weight of 204 lbs, the DuroMax XP8500EH 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.
  • As this generator can emit noise as low as 72 dBA, it finds itself in the average expected noise for this kind of power. If noise emissions are important to you, one of the least noisy generators of this power range is the Powerhorse 7500i with only 55 dBA.
  • Given that the XP8500EH reaches an autonomy of around 10 hours with a full tank and at 50% load, it is placed within the average autonomy range of similarly powerful generators. If concerned with autonomy, one of the products of a comparable power output, which offers the highest run time, is the Generac XC6500, boasting with 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 not fuel efficient compared to devices of similar output: its estimated fuel consumption stands at 0.79 GPH at a 50% load. If not satisfied with the afore-mentioned fuel consumption, you may wish to check out the Lifan ESI 7000iER-EFI. With a fuel consumption of as little as 0.38 GPH, it is one of the most efficient generators currently on the market.

Price comparison

As you can see from this interactive chart, when compared to other 6500-7500W generators, the DuroMax XP8500EH is on the average side of the price range.

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