Zoom on the WEN GN875i
In a nutshell, the WEN GN875i is a powerful portable inverter generator mostly geared towards:
- Food truck owners who do not wish to see their business interrupted under any circumstances
- Homeowners who want to be sure of their ability to power their fridges, cooking tools, heating and lighting equipment during power failures
- Tailgating and campground aficionados with the desire of enjoying power anywhere they go
- RV travellers looking for even more independence
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 WEN GN875i's engine, 420 cc OHV 4-stroke, fueled by gasoline, can deliver 120/240V. It provides a running wattage of 7000W and reaches a peak wattage of 8750W.
This inverter generator features a simple traditional pull-start mechanism and also a convenient and easy-to-use electric starter (battery included).
Thanks to a fuel capacity of 4.2 gallons, the GN875i can operate for around 6.7 hours at 50% load with a full tank (fuel consumption around 0.63 GPH).
The GN875i produces a clean sine wave: thanks to a <1.5% Total Harmonic Disruption (THD), your sensitive electronics can be safely plugged in the AC outlets.
The control panel includes the following 6 AC outlets:
Additionally, it features 2 DC outlets: there's two 5V USB ports with which charging of electronics like mobile phones and tablets is made convenient.
Thanks to its TT-30R receptacle (TT stands for 'Travel Trailer'), this WEN generator is RV Ready. In addition, because the GN875i 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.
With its dimensions of L26.8 x W26.4 x H23.2 in, the conventional, open frame design of the WEN GN875i offers stability and allows the generator to be raised above ground level. The generator is designed for ideal use outdoors and in rough environments.
Although this generator is technically considered 'portable' (in the sense that it can be moved), its 136.7 lbs make it incredibly difficult to manually lift and transport. However, its challenging mobility is solved by its set of wheels and its folding handle, which will ease its displacement, once it is on the floor.
The control panel of the GN875i includes a convenient meter, which displays voltage, frequency and lifetime hours, helpful for the monitoring of its status and activity.
In addition to this info, some light indicators allow you to instantly see if the generator is ready, its oil levels are insufficient 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 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.
With the basic documentation and an owner's manual (opens in a new tab), letting you start the generator quickly, the WEN GN875i also comes with several accessories, including: 2 altitude kits and tool kit.
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, so it is adequate 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 matters to you, one of the champions in this power range is the Sportsman GEN85KIDF with only 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. Concerning the run times, one of the several devices with a comparable output, offering the highest autonomy, is the Generac XC6500, which is able to run for around 14 hours.
- Run times are important, yet thanks to their dependence on the fuel capacity, they should be judged along with the fuel consumption of the device. This inverter generator has an estimated fuel consumption of roughly 0.63 GPH (gallon per hour) at a 50% load, rendering it somewhat average compared to devices of a similar output. 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.
As you can see from this interactive chart, when compared to other 6500-7500W generators, the WEN GN875i is on the average side of the price range.
Therefore, this generator nicely fits in the expected budget for this kind of product.

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.
