Description

Zoom on the Genmax GM2200i

In summary, the Genmax GM2200i is a quiet, compact and lightweight portable inverter generator especially useful for:

  • Tailgating and campground aficionados with the desire of enjoying power anywhere they go
  • Handcrafting enthusiasts who wish to work on-the-go

In the following paragraphs, we shall explore the power characteristics, available outlets, portability, and any additional features of the device.

Power & Run Time

The Genmax GM2200i in use

The Genmax GM2200i

Genmax GM2200i is equipped with a 79.7 cc Dinking OHV 4-stroke engine, running on gasoline and providing 120V, boasting a running wattage of 1,800W alongside a starting wattage of 2,200W. Moreover, the parallel capability (parallel kit (opens in a new tab) not included) allows for doubling of power output when paired with another similar or compatible unit, providing increased energy capacity and reliability for diverse needs.

With a noise rating of 58 dBA (less noisy than a refrigerator), the inverter generator features a standard recoil pull-rope starting mechanism.

Equipped with a 1 gallon fuel tank, the GM2200i ensures continuous operation for up to 8 hours with a full tank (fuel usage approximately 0.13 gallons per hour).

As the GM2200i produces a clean sine wave, with a <3% Total Harmonic Distortion (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)

In addition, it provides 2 DC outlets: there's two 5V USB ports (USB-A) providing convenient charging capabilities for mobile phones, tablets, and other electronic devices.

Portability

As an inverter generator, the Genmax GM2200i showcases a closed design (L18.9 x W11.4 x H17.3 in), enhancing aesthetics and ensuring quieter operation compared to conventional, open frame models. The design follows the contemporary trends and is perfect for recreationally generating power.

The GM2200i's weight, at just 41.9 lbs, makes it an ideal choice for those seeking a lightweight and portable generator. The device can be easily moved by just one person and thus, its power may be enjoyed on-the-go. The inclusion of a handle (molded in the case) makes carrying it a breeze, adding to its convenience.

Features

Panel of the Genmax GM2200i

The GM2200i's control panel

When the oil level is too low, the generator is ready and the generator is on overload, you will be informed by the featured light indicators.

Security-wise, this product benefits from an overload protection (circuit breaker) and an automatic low oil shut-off, which gives you a complete peace of mind when using it.

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.

Apart from the standard documentation and an owner's manual (opens in a new tab) to facilitate setup, the Genmax GM2200i features extra accessories: funnel and tool kit.

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).

  • Considering its weight, the Genmax GM2200i registers at a modest 41.9 pounds, placing it among the lighter inverter generators in the 1500 to 2500 rated wattage selection. If weight is a key factor for your needs, the Genmax GM2000i is noteworthy for being one of the top contenders in this power range, with a dry weight of 34.2 pounds.
  • Because this inverter generator emits noise as low as 58 dBA, it can be considered to have a pretty average expected noise rating for a device of its power. If you wish to prioritize minimal noise, the Honda EU2200i stands out as one of the quietest options among generators of similar power, with a rating of 48 dBA.
  • In terms of autonomy, the GM2200i offers up to 8 hours at a 25% load, placing it at the lower range within its type and power range. If runtime is a priority for you, the DuroMax XP2300iH stands out as one of the generators with the longest run time in its power range, providing up to 13 hours of continuous use.
  • Run time is a key metric, but it's dependent on the generator's fuel tank capacity. Therefore, discussing fuel efficiency is necessary for a complete understanding. In terms of fuel efficiency within its wattage range, this inverter generator falls short: it consumes approximately 0.13 GPH at a 25% load. If you are concerned with gasoline efficiency, having a fuel consumption of just 0.08 GPH, the Westinghouse iGen2800c is a device you could look out for.

Price comparison

As you can see from these interactive charts, 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.
