Power & Run Time

The Genmax GM2800iAE in use

The Genmax GM2800iAE

The Genmax GM2800iAE's core is the 145 cc Dinking OHV 4-stroke engine, which runs on gasoline. With an output of 120V, it provides a running wattage of 2,500W and a peak wattage of 2,800W. In addition, the parallel capability (parallel kit not included) empowers doubling of power output when linked to another similar or compatible unit, ensuring expanded energy capacity and reliability for various applications.

Enjoying a noise rating of 62 dBA (just slightly more noisy than an office), this inverter generator offers the versatility of starting with either a manual recoil starter system or an easy-to-use and reliable electric starter (battery included). Moreover, the GM2800iAE boasts remote starting functionality, adding another layer of convenience (key fob included).

Thanks to its 1.7 gallon fuel tank, the GM2800iAE can run continuously for up to 10 hours on a full tank (with an average fuel consumption of approximately 0.17 GPH).

The GM2800iAE produces a clean sine wave: thanks to a <3% Total Harmonic Distortion (THD), your sensitive electronics can be safely plugged in the AC outlets.


The control panel is equipped with the following 3 AC outlets:

Duplex 120V 20A (5-20R)
120V 30A (TT-30R) receptacle

Furthermore, it showcases 2 DC outlets: there's two 5V USB ports (USB-A) with which you may charge electronics, for example mobile phones or tablets, conveniently.

This Genmax generator is RV Ready, as it features a TT-30R receptacle (TT stands for 'Travel Trailer').


Thanks to its closed inverter generator design (L20.7 x W12.2 x H19.7 in), the Genmax GM2800iAE not only offers superior aesthetics but also operates with reduced noise levels compared to a typical, open frame generator. The generator has a contemporary design, convenient for recreationally generating power.

The 54 lbs of the GM2800iAE's dry weight enables you to use it anywhere you will ever need. Furthermore, with its set of 2 wheels (⌀4") and its handle (molded in the case), you can easily relocate the generator once it's set up.

The GM2800iAE's control panel

Enhancing monitoring capabilities, the GM2800iAE features a digital data center within its control panel, furnishing essential details on the fuel level, voltage, frequency, lifetime run hours and power output for tracking activity and status.

In addition to this info, the generator's light indicators provide visual feedback when the generator is on overload, the generator is ready and its oil levels are insufficient.

As far as security is concerned, the generator comes with an overload protection (circuit breaker) and an automatic low oil shut-off, providing peace of mind during use.

It also benefits from Genmax's CO DETECT technology, which is designed to monitor the level of carbon monoxide present during the generator's operation. If the generator is positioned incorrectly and carbon monoxide levels rise to an unsafe level, the generator will automatically shut down.

Along the basic documentation and an owner's manual (opens in a new tab), useful for starting the generator right away, the Genmax GM2800iAE's package also includes these accessories: key fob, tool kit and funnel.

The Genmax GM2800iAE versus other generators

The following charts are provided to give you an idea of how some of the key specs of the Genmax GM2800iAE compare to inverter generators of similar power (between 2000 and 3000 W).

  • Weight-wise, the Genmax GM2800iAE has only 54 lbs, which renders it one of the lighter inverter generators which produce 2000 to 3000 rated watts. In terms of weight, one of the champions in their power range is the WEN 56360i, standing at just 46.3 lbs.
  • When comparing it to devices with a similar running wattage, this inverter generator's lowest noise level of 62 dBA puts it alongside the noisier units. If noise emissions are important to you, one of the least noisy generators of this power range is the Honda EU3000iS with only 50 dBA.
  • With a runtime of up to 10 hours under a 25% load on a full tank, the GM2800iAE falls within the average autonomy range among the inverter generators of a similar power. Furthermore, considering the run times, one of the generators which have a roughly same power output, with the highest autonomy, is the Honda EU3000iS, as it provides up to 20 hours.
  • Run time is crucial, but it heavily relies on the fuel tank's capacity. Thus, considering fuel efficiency alongside is essential. With an estimated fuel consumption of 0.17 GPH at a 25% load, this inverter generator aligns with the average gasoline usage range of comparable products. If you wish to further improve in the area of fuel efficiency, the Westinghouse iGen2800, which boasts with a gas consumption of only 0.08 GPH, may be the right generator for you.

Price comparison

As you can see from these interactive charts, when compared to other 2000-3000W inverter generators, the Genmax GM2800iAE 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.
