Zoom on the DuroMax XP9000iH

In summary, the DuroMax XP9000iH is a powerful portable inverter generator especially useful for:

  • Food van owners who know that just a short power outage could lose them hundreds of dollars
  • Homeowners in need of an emergency backup power for their essentials
  • Camping and tailgating hobbyists looking for a portable power source

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 XP9000iH in use

The DuroMax XP9000iH

The dual-fuel technology of the DuroMax XP9000iH allows for an output of 120/240V and provides superb power and versatility. If gasoline-powered, the device provides a running wattage of 7600W and a starting wattage of 9000W. If propane-powered, it gives 7200 rated watts and 8550 starting watts. Moreover, since it is parallel capable (XP9000iH-PK parallel kit (opens in a new tab) not included), its power may be increased if linked to a second compatible unit.

DuroMax’s Switch On Demand technology allows you to switch from propane to gasoline or from gasoline to propane while the generator is running.

The inverter generator is rated for a noise of 68 dBA (less noisy than a normal conversation). Its starting mechanisms include a conventional pull-start mechanism and a convenient and easy-to-use electric starter (battery included). For additional convenience, the XP9000iH may also be remotely started (key fob included).

With a fuel capacity of 6.9 gallons, the XP9000iH can operate for around 11 hours at 50% load using gasoline (fuel consumption around 0.63 GPH), or for around 4.5 hours (on a 20 lbs tank - propane consumption around 1.04 GPH) using propane.

The XP9000iH produces a clean sine wave: thanks to a <5% Total Harmonic Disruption (THD), your sensitive electronics can be safely plugged in the AC outlets.

Outlets

The control panel includes the following 6 AC outlets:

Two Duplexes 120V 20A (5-20R)
120V 30A (L5-30R) receptacle
120/240V 30A (L14-30R) receptacle

Additionally, it features 2 DC outlets: there's two 5V USB ports (1 x USB-A and 1 x USB-C) allowing you to conveniently charge electronics such as mobile phones and tablets.

Even if this DuroMax generator isn't quite RV Ready, it still allows for an easy RV connection via an L5-30P to TT-30R adaptor, thanks to its L5-30R receptacle. Besides, as it features a twist-lock L14-30R receptacle, the XP9000iH is transfer switch ready: in case of a power outage, you will be easily able to connect it to a breaker box and power your household. The unit also features an ATS plug, which makes it compatible with automatic transfer switches.

Portability

Since the DuroMax XP9000iH is an inverter generator, its closed design (L27 x W21 x H25 in) has an esthetical advantage over conventional, open frame devices. The design follows the contemporary trends and is perfect for recreationally generating power.

Even though this device may be technically portable (as in movable), manipulation and transportation without special equipment can be a challenge, as it weighs 237 pounds. Nevertheless, thanks to its set of 4 wheels and its folding handle (a decent solution to its lack of maneuverability), the generator can be easily moved, once placed the ground.

Features

The XP9000iH's control panel

Monitoring of the XP9000iH's status and activity is made possible by a digital data center, which provides information on the frequency, power output, voltage and lifetime run hours and is one of the features of its control panel.

In addition to this info, some light indicators allow you to instantly see if the generator is ready, the oil level is too low and the generator is overloaded.

Thanks to a built-in fuel gauge, the inverter generator allows you to quickly, conveniently and easily check the gas level at a glance.

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.

Along the basic documentation and an owner's manual (opens in a new tab), useful for starting the generator right away, the DuroMax XP9000iH's package also includes these accessories: battery charger, tool kit, propane hose, funnel and key fob.

Emissions

The DuroMax XP9000iH 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, which makes it suitable for use in forested areas.

The DuroMax XP9000iH versus other generators

The following charts are provided to give you an idea of how some of the key specs of the DuroMax XP9000iH compare to generators of similar power (between 7500 and 8500 W).

  • As its dry weight is 237 pounds, the DuroMax XP9000iH is one of the heavier of the products which can generate 7500 to 8500 running watts. Regarding dry weight, one of the champions in the same power range is the Dewalt DXGNR8000, with a dry weight of only 183 lbs.
  • With a lowest noise rating of 68 dBA, the inverter generator is one of the more quiet of the generators of similar power. For those who are looking for a less noisy device, we suggest the Predator 9500. With just 67 dBA, it is one of the most quiet devices in this power range.
  • Since the XP9000iH boasts with a run time of around 11 hours at 50% load, it can be safely judged as a device of a higher run time than most generators of a comparable output. If autonomy is your priority, one of the devices of a similar power output with the highest run time is the Champion 100416, reaching around 12.5 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 inverter generator can be considered as fuel efficient, due to its low estimated fuel consumption of only 0.63 GPH (gallon per hour) at 50% load, within the aforementioned wattage range. If you wish to acquire one of the most gasoline efficient products of this power range, the Pulsar PG10000B16, with a fuel consumption of 0.55 GPH could be in your good books.
According to our stats, the following comparison is pretty popular: DuroMax XP9000iH vs Predator 9500.

Price comparison

As you can see from this interactive chart, when compared to other 7500-8500W generators, the DuroMax XP9000iH is on the expensive side of the price range.

While certainly not the cheapest of its kind, purchasing it would most likely also mean enjoying the reliability of a high-end product.
