Description

Zoom on the Genmax GM1200i

In a nutshell, the Genmax GM1200i is a quiet, compact and lightweight portable inverter generator mostly geared towards:

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

Over the following sections, you'll uncover its power characteristics, the selection of outlets it offers, its overall portability, and the supplementary features it includes.

Power & Run Time

The Genmax GM1200i in use

The Genmax GM1200i

Featuring a 57 cc Dinking OHV 4-stroke engine, the Genmax GM1200i operates using gasoline, providing 120V, with a running wattage of 1,000W and a starting wattage of 1,200W. Additionally, the parallel capability (parallel kit included) facilitates doubling of power output when linked to another similar or compatible unit, offering enhanced energy capacity and reliability for diverse requirements.

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

With a fuel capacity of 0.7 gallon, the GM1200i can run for up to 10 hours when the tank is full (fuel consumption is approximately 0.07 gallons per hour).

Thanks to its low <3% Total Harmonic Distortion (THD), the GM1200i produces a clean sine wave output, making it safe for your sensitive electronics when utilizing the AC outlets.

Outlets

The control panel features 2 AC outlets as follows:

Duplex 120V 20A (5-20R)

Moreover, it comes equipped with 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

With its enclosed inverter generator design (L16.5 x W9.5 x H15.7 in), the Genmax GM1200i offers superior aesthetics and operates with minimized noise levels, distinguishing itself from standard, open frame generators. The design follows the contemporary trends and is perfect for recreationally generating power.

Considered a lightweight portable generator, the GM1200i weighs just 25.3 lbs. With its manageable weight, one person can easily move it around, ensuring power wherever needed. Its handle (molded in the case) adds to the convenience, making it easy to carry.

Good to know: This unit ranks 4th in our list of the 10 smallest portable generators.

Features

Panel of the Genmax GM1200i

The GM1200i's control panel

Light indicators on the device will signal if the generator is ready, the generator is on overload and the oil level is too low.

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

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 typical documentation and an owner's manual (opens in a new tab), which lets you start it right away, the Genmax GM1200i also is packed along with the following accessories: RV adapter, funnel and tool kit.

The Genmax GM1200i versus other generators

The following charts are provided to give you an idea of how some of the key specs of the Genmax GM1200i compare to inverter generators of similar power (between 1000 and 2000 W).

  • Regarding weight, the Genmax GM1200i comes in at only 25.3 pounds, positioning itself as one of the lighter options among inverter generators spanning from 1000 to 2000 in rated wattage. If weight is your top priority, one of the champions in this power category is the Pulsar PGD16iSCO, weighing just 24 pounds.
  • As this inverter generator has its lowest possible noise of 58 dBA, it should be considered noisier compared to its peers of a comparable running wattage. If noise emissions are important to you, one of the least noisy generators of this power range is the Honda EU2200i with only 48 dBA.
  • At a 25% load, the GM1200i offers up to 10 hours of runtime on a full tank, placing it within the average autonomy range among inverter generators of similar power level. 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.
  • Autonomy holds its importance, however, it is largely dependent on the generator’s fuel capacity and so, it is nonsensible to discuss it without mentioning fuel efficiency as well. With a fuel consumption rate around 0.07 GPH (gallon per hour) at 25% load, this inverter generator is one of the most fuel-efficient models within the aforementioned wattage range.

Price comparison

As you can see from these interactive charts, when compared to other 1000-2000W inverter generators, the Genmax GM1200i 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.
