Zoom on the WEN GN875i
In summary, the WEN GN875i is a powerful portable inverter 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
- Homeowners who want to be able to use the most necessary devices in their household, even during a blackout
- Camping and tailgating buffs looking to enhance their experience
- RV travellers wishing to enhance their freedom and nomad lifestyle
Power & Run Time
The WEN GN875i's core is the 420 cc OHV 4-stroke engine, which runs on gasoline. With an output of 120/240V, it provides a running wattage of 7,000W and a peak wattage of 8,750W.
This inverter generator features a simple traditional pull-start mechanism, but also a simple and elegant electric starter (battery included).
The GN875i can operate for around 6.7 hours at 50% load with a full tank (fuel consumption around 0.63 GPH), due to its fuel capacity of 4.2 gallons.
Delicate electronics can be plugged in an AC outlets safely, as the GN875i generates a clean sine wave, reaching a <1.5% Total Harmonic Distortion (THD).
The control panel provides the upcoming 6 AC outlets:
It also sports 2 DC outlets: there's two 5V USB ports with which you may charge electronics, for example mobile phones or tablets, conveniently.
With its TT-30R receptacle (TT as in 'Travel Trailer'), this WEN generator is RV Ready. In addition, since the GN875i 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.
The design of the WEN GN875i is a typical, open frame, with the dimensions of L26.8 x W26.4 x H23.2 in, offering support and stability and enabling the possibility of raising it above ground level. The design is ideal for rough 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 136.7 lbs. Nevertheless, thanks to its set of wheels and its folding handle (a decent solution to its lack of maneuverability), the generator can be easily moved, once placed the ground.
The GN875i and its control panel include a convenient meter, which displays voltage, frequency and lifetime hours. This feature comes handy when monitoring its status and activity.
In addition to this info, some light indicators allow you to instantly see if the generator is ready, the generator is on overload and the oil level is too low.
The inverter 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 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 WEN GN875i's package also includes these accessories: tool kit and 2 altitude kits. An official storage cover is also available, as a separate purchase.
The WEN GN875i 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, which makes it suitable for use in forested areas.
The WEN GN875i versus other generators
The following charts are provided to give you an idea of how some of the key specs of the WEN GN875i compare to generators of similar power (between 6500 and 7500 W).
- Weight-wise, the WEN GN875i has only 136.7 lbs, which renders it one of the lighter 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 GN875i's autonomy is somewhat low end compared to devices of its power range, as it reaches only around 6.7 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 Predator 9000, reaching around 13 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 inverter generator is one of the more fuel efficient models of the aforementioned output range, as its estimated fuel consumption reaches just 0.63 GPH (gallon per hour) at 50% load. If you wish to further improve in the area of fuel efficiency, the Energizer eZV7500, which boasts with a gas consumption of only 0.45 GPH, may be the right generator for you.
As you can see from this interactive chart, when compared to other 6500-7500W inverter generators, the WEN GN875i is on the cheap side of the price range.
It can therefore be a really good buy if you're looking to acquire a budget generator.

Can you retrofit a larger fuel tank or add an extended tank. I like the unit but for extended emergency operations it is a very short full tank run time. Didn't see any other options on the Wen site (Asked January 24, 2022)
It could be possible to add an extended tank, but keep in mind that gasoline is gravity-fed.
