Description

Zoom on the Genmax GM2200i

In a nutshell, the Genmax GM2200i is a quiet, compact and lightweight portable inverter generator mostly geared towards:

  • Camping and tailgating hobbyists looking for a portable power source
  • Amateur DIY lovers

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 GM2200i in use

The Genmax GM2200i

The Genmax GM2200i's engine, 79.7 cc Dinking OHV 4-stroke, fueled by gasoline, can deliver 120V. It provides a running wattage of 1800W and reaches a peak wattage of 2200W. In addition, as it is parallel capable (parallel kit (opens in a new tab) not included), this power can be doubled when linked to another similar or compatible unit.

With a noise rating of 58 dBA (less noisy than a quiet suburb), the inverter generator features a simple traditional pull-start mechanism.

With a full tank, the GM2200i can operate for up to 8 hours (fuel consumption around 0.13 GPH), thanks to its fuel capacity of 1 gallon.

As the GM2200i 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 2 AC outlets:

Duplex 120V 20A (5-20R)

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.

Portability

Since the Genmax GM2200i is an inverter generator, its closed design (L18.9 x W11.4 x H17.3 in) has an esthetical advantage over conventional, open frame devices. The generator has a contemporary design, convenient for recreationally generating power.

Labeled a lightweight portable generator, the GM2200i weighs just 41.9 lbs. The device can be easily moved by just one person and thus, its power may be enjoyed on-the-go. This convenience is further enhanced thanks to its handle (molded in the case) that allows you to carry it with ease.

Features

Panel of the Genmax GM2200i

The GM2200i's control panel

Several light indicators serve to show you when the generator is on overload, its oil levels are insufficient and the generator is ready.

As far as security is concerned, the generator can be used with a peace of mind, as it features an overload protection (circuit breaker) and an automatic low oil shut-off.

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).

With the basic documentation and an owner's manual (opens in a new tab), letting you start the generator quickly, the Genmax GM2200i also comes with several accessories, including: funnel and tool kit.

Emissions

The Genmax GM2200i 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 GM2200i versus other generators

The following charts are provided to give you an idea of how some of the key specs of the Genmax GM2200i compare to inverter generators of similar power (between 1500 and 2500 W).

  • Regarding its weight, the Genmax GM2200i only weighs in at 41.9 pounds, which means it's one of the lighter inverter generators in the 1500-2500 rated wattage range. Regarding dry weight, one of the champions in the same power range is the Genmax GM2000i, with a dry weight of only 34.2 lbs.
  • Among the generators of a comparable running wattage, this inverter generator with a lowest noise of 58 dBA can be judged as noisy. If noise emissions are one of your priorities, you may be interested in the Honda EU2200i, one of the least noisy generators similarly powerful as this one, rated for 48 dBA.
  • As far as autonomy is concerned, providing up to 8 hours of runtime with a full tank at a 25% load, the GM2200i falls into the low end in comparison with other inverters of a comparable power output. Concerning the run times, one of the several devices with a comparable output, offering the highest autonomy, is the DuroMax XP2300iH, which is able to run for up to 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. In fact, this inverter generator is not among the most fuel efficient, within the aforementioned wattage range : its estimated gasoline consumption at 25% load is around 0.13 GPH. If not satisfied with the afore-mentioned fuel consumption, you may wish to check out the DuroMax XP2300iH. With a fuel consumption of as little as 0.08 GPH, it is one of the most efficient generators currently on the market.

Price comparison

As you can see from this interactive chart, when compared to other 1500-2500W inverter generators, the Genmax GM2200i 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.
