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 a nutshell, the DuroMax XP8500EH is a portable generator mostly geared towards:

  • 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 in need of safely powering high-intensity work or lighting equipment

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 dual-fuel technology of the DuroMax XP8500EH allows for an output of 120/240V and provides superb power and versatility. If gasoline-powered, the device provides a running wattage of 7000W and a starting wattage of 8500W. If propane-powered, it gives 6650 rated watts and 8075 starting watts.

The generator features a conventional pull-start mechanism and also a convenient and easy-to-use electric starter (battery included). It is rated for a noise of 72 dBA (just slightly more noisy than a vacuum cleaner).

Regarding its running time, the XP8500EH, with a 7.9 gallons fuel capacity can operate for around 10 hours at 50% load with a full tank of gasoline (fuel consumption around 0.79 GPH). When using propane, it can run for around 5 hours (on a 20 lbs tank - propane consumption around 0.94 GPH).

The XP8500EH is unsuitable for the powering of sensitive electronic devices 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

Additionally, it features 3 DC outlets: there's a 12V 8A output with which you may charge your batteries with ease 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

The DuroMax XP8500EH 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. The generator is designed for ideal use outdoors and in rough environments.

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. 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

Panel of the DuroMax XP8500EH

The XP8500EH's control panel

The XP8500EH and its control panel include a convenient meter showing you voltage, frequency and lifetime hours. This feature comes handy when monitoring its status and activity.

The generator allows for a quick, easy and convenient assessment of its gas level, as it is equipped with a built-in fuel gauge.

From a security point of view, the generator is equipped with an overload protection (circuit breaker) and an automatic low oil shut-off, giving you a peace of mind during use.

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

Emissions

The DuroMax XP8500EH 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 therefore, can be used 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).

  • Since the generator weighs in at a dry weight of 204 lbs, the DuroMax XP8500EH 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.
  • This generator has a somewhat average expected noise for its power range, rated at 72 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 XP8500EH's autonomy is somewhat low end compared to devices of its power range, as it reaches only around 10 hours at 50% load on a full tank. If autonomy is your priority, one of the devices of a similar power output with the highest run time is the Generac XC6500, reaching around 14 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 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 wish to further improve in the area of fuel efficiency, the Lifan ESI 7000iER-EFI, which boasts with a gas consumption of only 0.38 GPH, may be the right generator for you.

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.
