Description

Zoom on the Genmax GM1200i

In summary, the Genmax GM1200i is a quiet, compact and lightweight portable inverter generator especially useful for:

  • Camping and tailgating buffs looking to enhance their experience
  • 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, along with its emission compliance information.

Power & Run Time

The Genmax GM1200i in use

The Genmax GM1200i

The Genmax GM1200i is powered by a 57 cc Dinking OHV 4-stroke engine. It delivers 120V, runs on gasoline and offers a running wattage of 1,000W as well as a peak wattage of 1,200W. Moreover, since it is parallel capable (parallel kit included), its power may be doubled if linked to a second compatible unit.

The inverter generator features a simple traditional pull-start mechanism. It is rated for a noise of 58 dBA (less noisy than a refrigerator).

Thanks to a fuel capacity of 0.7 gallon, the GM1200i can operate for up to 10 hours with a full tank (fuel consumption around 0.07 GPH).

As the GM1200i 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 includes the following 2 AC outlets:

Duplex 120V 20A (5-20R)

Additionally, it features 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 GM1200i is an inverter generator, its closed design (L16.5 x W9.5 x H15.7 in) has an esthetical advantage over conventional, open frame devices. The generator has a contemporary design, convenient for recreationally generating power.

The GM1200i is a lightweight, portable generator, as it only weighs 25.3 lbs. The product’s power can be enjoyed on-the-go, as it can be moved by a single person without trouble. Its handle (molded in the case) allows you to carry it easily, further enhancing its convenience.

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

The light indicators show you if the generator is ready, the oil level is too low and the generator is overloaded.

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.

Besides the classic documentation and an owner's manual (opens in a new tab) to get you promptly started, the Genmax GM1200i also comes with some accessories: RV adapter, funnel and tool kit are included.

Emissions

The Genmax GM1200i is EPA approved, but NOT CARB-compliant. Thus, it cannot be purchased or sold in California.

However, it features a spark arrestor, so it is adequate for use in forested areas.

In addition, the unit meets the ANSI/PGMA G300-2018 safety and performance requirements.

Product Videos

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 its weight, the Genmax GM1200i only weighs in at 25.3 pounds, which means it's one of the lighter inverter generators in the 1000-2000 rated wattage range. If you are concerned by weight, one of the champions in the above-mentioned power range is the Pulsar PGD16iSCO, with a dry weight of just 24 pounds.
  • 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.
  • Given that the GM1200i 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. If autonomy is your priority, one of the devices of a similar power output with the highest run time is the DuroMax XP2300iH, reaching up to 13 hours.
  • Run times are important, yet thanks to their dependence on the fuel capacity, they should be judged along with the fuel consumption of the device. This inverter generator is one of the most fuel efficient models of the aforementioned output range, as its estimated fuel consumption reaches just 0.07 GPH (gallon per hour) at 25% load.

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.
