Description

Zoom on the Genmax GM2800iAE

In summary, the Genmax GM2800iAE is a compact and lightweight portable inverter generator especially useful for:

  • Camping and tailgating hobbyists looking for a portable power source
  • Amateur DIY lovers
  • Homeowners in need of an emergency backup power for their essentials
  • RV travellers who wish to upgrade their experience to another level

In the following paragraphs, we shall explore the power characteristics, available outlets, portability, and any additional features of the device, along with its emission compliance information.

Power & Run Time

The Genmax GM2800iAE in use

The Genmax GM2800iAE

The Genmax GM2800iAE's design includes a gasoline-fueled 145 cc Dinking OHV 4-stroke engine. With a 120V output, it gives a running wattage of 2,500W and also a peak wattage of 2,800W. In addition, as it is parallel capable (parallel kit not included), this power can be doubled when linked to another similar or compatible unit.

At a noise rating of 62 dBA (just slightly more noisy than background music), this inverter generator can be started via a conventional pull-start mechanism, or a convenient and easy-to-use electric starter (battery included). To add further convenience, the GM2800iAE can be remotely started (key fob included).

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

Delicate electronics can be plugged in an AC outlets safely, as the GM2800iAE generates a clean sine wave, reaching a <3% Total Harmonic Distortion (THD).

Outlets

The control panel features the following 3 AC outlets:

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

Furthermore, it has 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').

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. The generator has a contemporary design, convenient for recreationally generating power.

The GM2800iAE can be taken anywhere with you, thanks to its weight of 54 lbs. Additionally, it can be easily moved with the help of its set of 2 wheels (⌀4") and its handle (molded in the case), once it is on the ground.

Features

Panel of the Genmax GM2800iAE

The GM2800iAE's control panel

To help you monitor the GM2800iAE's status and activity, its control panel is equipped with a digital data center, giving you information on the power output, frequency, lifetime run hours, fuel level and voltage.

In addition to this info, when the oil level is too low, the generator is overloaded and the generator is ready, you will be informed by the featured light indicators.

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.

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.

With the basic documentation and an owner's manual (opens in a new tab), letting you start the generator quickly, the Genmax GM2800iAE also comes with several accessories, including: funnel, tool kit and key fob.

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 thus, may 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).

  • 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. If weight is your top priority, one of the champions in this power category is the WEN 56360i, weighing just 46.3 pounds.
  • Among the generators of a comparable running wattage, this inverter generator with a lowest noise of 62 dBA can be judged as noisy. If you’d prefer a less noisy device, one of the most quiet devices, which share the same power range with this one, is the Honda EU3000iS, whose lowest noise levels reach just 50 dBA.
  • As the GM2800iAE offers up to 10 hours run time on a full tank at a 25% load, it falls within the average autonomy range among the inverter generators of a similar power. If you consider autonomy on a single full tank as one of the deciding factors, one of the generators in the same power range that offers the highest run time is the Honda EU3000iS, with 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. As this inverter generator uses an estimated 0.17 GPH (gallon per hour) at a 25% load, it finds itself in the average gasoline consumption range of similar products. If you wish to acquire one of the most gasoline efficient products of this power range, the Westinghouse iGen2800, with a fuel consumption of 0.08 GPH could be in your good books.

Price comparison

As you can see from these interactive charts, 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.
