Description

Zoom on the Genmax GM2800iAE

In a nutshell, the Genmax GM2800iAE is a compact and lightweight portable inverter generator mostly geared towards:

  • Tailgating and campground aficionados with the desire of enjoying power anywhere they go
  • DIYers who wish to improve their efficiency with tools
  • Homeowners who want to be sure of their ability to power their fridges, cooking tools, heating and lighting equipment during power failures
  • RV travellers looking for even more independence

The following sections will present you in detail its power characteristics, the different outlets it offers, its overall portability, the extra features it benefits from, and any relevant emission compliance details.

Power & Run Time

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 2500W and a peak wattage of 2800W. Additionally, as the generator is parallel capable (parallel kit not included), it can be linked to a second unit for more power.

Enjoying a noise rating of 62 dBA (just slightly more noisy than an office), this inverter generator can be started thanks to a conventional pull-start mechanism, but also to a simple and elegant electric starter (battery included). For additional convenience, the GM2800iAE may also be remotely started (key fob included).

With a full tank, the GM2800iAE can operate for up to 10 hours (fuel consumption around 0.17 GPH), thanks to its fuel capacity of 1.7 gallon.

As the GM2800iAE produces a clean sine wave, with a <3% Total Harmonic Disruption (THD), sensitive electronics may be plugged in the AC outlets safely.

Outlets

The control panel features the following 3 AC outlets:

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

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

Thanks to its TT-30R receptacle (TT stands for 'Travel Trailer'), this Genmax generator is RV Ready.

Portability

The Genmax GM2800iAE is an inverter generator and has an encased design of the following dimensions: L20.7 x W12.2 x H19.7 in. Thus, it is more aesthetical than conventional, open frame products. This type of design is the most modern and convenient way to recreationally generate power.

The GM2800iAE can be taken anywhere with you, thanks to its weight of 54 lbs. Moreover, its set of 2 wheels (⌀4") and its handle (molded in the case) will allow you to effortlessly shift it once it's on the ground.

Features

The GM2800iAE's control panel

Monitoring of the GM2800iAE's status and activity is made possible by a digital data center, which provides information on the frequency, fuel level, voltage, lifetime run hours and power output and is one of the features of its control panel.

In addition to this info, when the generator is ready, its oil levels are insufficient and the generator is overloaded, you will be informed by the featured light indicators.

From a security point of view, the generator is equipped with an automatic low oil shut-off and an overload protection (circuit breaker), giving you a 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. It’s a welcomed additional security feature, but don’t forget to always take your generator outside (opens in a new tab).

Apart from the typical documentation and an owner's manual (opens in a new tab), which lets you start it right away, the Genmax GM2800iAE also is packed along with the following accessories: key fob, funnel and tool kit.

Emissions

The Genmax GM2800iAE is EPA approved, but NOT CARB-compliant. Thus, it cannot be purchased or sold in California.

However, it features a spark arrestor and therefore, can be used in forested areas.

In addition, the unit meets the ANSI/PGMA G300-2018 safety and performance requirements.

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).

  • In terms of its dry weight, the Genmax GM2800iAE stands at only 54 lbs, meaning that is one of the lighter inverters of the 2000-3000 rated wattage category Regarding dry weight, one of the champions in the same power range is the Westinghouse iGen2500, with a dry weight of only 46.3 lbs.
  • If compared to generators capable of producing a similar running wattage, this inverter generator with a lowest emitted noise of 62 dBA can be considered somewhat noisy. For those who are looking for a less noisy device, we suggest the Honda EU3000iS. With just 50 dBA, it is one of the most quiet devices in this power range.
  • The GM2800iAE, offering a run time of up to 10 hours with a full tank at a 25% load, falls within the average autonomy range when compared to its peers. Concerning the run times, one of the several devices with a comparable output, offering the highest autonomy, is the Honda EU3000iS, which is able to run for up to 20 hours.
  • Even though run times are undoubtedly important, they are dependent on the fuel capacity to a large extent. For a more wholesome picture, we must take into consideration the fuel consumption of the generator. This inverter generator has an average fuel consumption among comparably powerful devices, as it reaches 0.17 GPH (gallon per hour) at a 25% load. If you wish to acquire one of the most gasoline efficient products of this power range, the Westinghouse iGen2500, with a fuel consumption of 0.1 GPH could be in your good books.

Price comparison

As you can see from this interactive chart, when compared to other 2000-3000W inverter generators, the Genmax GM2800iAE is on the average side of the price range.

Therefore, this generator nicely fits in the expected budget for this kind of product.
