Description

Zoom on the Genmax GM2000i

To sum up, the Genmax GM2000i is a quiet, compact and lightweight portable inverter generator tailored for:

  • Camping and tailgating hobbyists looking for a portable power source
  • DIYers who wish to improve their efficiency with tools

In the forthcoming sections, you'll delve into its power characteristics, the various outlets it offers, its overall portability, and the additional features it boasts.

Power & Run Time

The Genmax GM2000i in use

The Genmax GM2000i

Genmax GM2000i runs on gasoline, powered by a 79.7 cc Dinking OHV 4-stroke engine, delivering 120V, boasting a running wattage of 1,600W alongside a starting wattage of 2,000W. In addition, the device is parallel capable (parallel kit (opens in a new tab) not included) and thus, can be linked to a similar or compatible unit for added power.

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

The GM2000i's fuel tank, boasting 1.1 gallon, allows it to operate for up to 10 hours with a full tank (with an estimated fuel consumption of 0.11 GPH).

The GM2000i ensures a clean sine wave output, boasting <3% Total Harmonic Distortion (THD) to protect your sensitive electronics when connected to its AC outlets.

Outlets

The control panel features the upcoming 2 AC outlets:

Duplex 120V 20A (5-20R)

It also sports 2 DC outlets: there's two 5V USB ports (USB-A) ensuring convenient charging of devices like mobile phones and tablets, for connectivity on the go.

Portability

Thanks to its closed inverter generator design (L18.7 x W10.6 x H15.9 in), the Genmax GM2000i not only offers superior aesthetics but also operates with reduced noise levels compared to a typical, open frame generator. The featured design follows the latest trends and is ideal for easy and recreational use.

With its weight totaling only 34.2 lbs, the GM2000i stands out as a lightweight generator. As it can be moved by a single person without much effort, the generator and its power can be enjoyed on-the-go. This convenience is further enhanced by its handle (molded in the case), which allows for easy carrying.

Features

The GM2000i's control panel

The generator's light indicators provide visual feedback when the generator is on overload, the generator is ready and the oil level is too low.

Considering security aspects, the generator boasts an overload protection (circuit breaker) and an automatic low oil shut-off, offering peace of mind throughout operation.

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 GM2000i features extra accessories: funnel and tool kit.

The Genmax GM2000i versus other generators

The following charts are provided to give you an idea of how some of the key specs of the Genmax GM2000i compare to inverter generators of similar power (between 1500 and 2500 W).

  • Weight-wise, the Genmax GM2000i has only 34.2 lbs, which renders it one of the lightest inverter generators which produce 1500 to 2500 rated watts.
  • This inverter generator, with its lowest noise level at 58 dBA, is noisier than most generators of comparable running wattage. 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.
  • Given that the GM2000i reaches an autonomy of up to 10 hours with a full tank and at 25% load, it is placed within the average autonomy range of similarly powerful inverter generators. For those prioritizing autonomy, the DuroMax XP2300iH could be considered, as it offers one of the longest run times among generators with similar power output, reaching up to 13 hours.
  • Run time is crucial, but it heavily relies on the fuel tank's capacity. Thus, considering fuel efficiency alongside is essential. This inverter generator has an estimated fuel consumption of roughly 0.11 GPH (gallon per hour) at a 25% load, rendering it somewhat average compared to devices of a similar output. If you wish to further improve in the area of fuel efficiency, the DuroMax XP2300iH, 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 1500-2500W inverter generators, the Genmax GM2000i 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.
