Description
Zoom on the Genmax GM1200i
In a nutshell, the Genmax GM1200i 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 sections ahead, the power characteristics, availability of various outlets, the portability, and any additional features of the device shall be discussed, including its emission compliance information.
Power & Run Time
The Genmax GM1200i
The Genmax GM1200i's engine, 57 cc Dinking OHV 4-stroke, fueled by gasoline, can deliver 120V. It provides a running wattage of 1,000W and reaches 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 is rated for a noise of 58 dBA (less noisy than rainfall). Its starting mechanism is based on a simple traditional pull-start mechanism.
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).
The GM1200i generates a clean sine wave: providing <3% Total Harmonic Distortion (THD), delicate electronics can be plugged in its AC outlets safely.
Outlets
The control panel features the following 2 AC outlets:
It also sports 2 DC outlets: there's two 5V USB ports (USB-A) allowing you to conveniently charge electronics such as mobile phones and tablets.
Portability
The Genmax GM1200i is an inverter generator and has an encased design of the following dimensions: L16.5 x W9.5 x H15.7 in. Thus, it is more aesthetical than conventional, open frame products. The featured design follows the latest trends and is ideal for easy and recreational use.
Since the GM1200i weighs only 25.3 lbs, it can be labeled as a portable lightweight generator. A single person should not have any problems moving it around and thus, enjoy power availability on-the-go. In addition, a handle (molded in the case) lets you carry it easily and further increases its convenience.
Good to know: This unit ranks 4th in our list of the 10 smallest portable generators.
Features
The GM1200i's control panel
The light indicators show you if its oil levels are insufficient, the generator is ready and the generator is on overload.
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.
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: funnel, RV adapter 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 lightest inverter generators in the 1000-2000 rated wattage range.
- 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 you are concerned with noise, check out the Honda EU2200i, which is one of the least noisy generators in its power range, with a noise rating of just 48 dBA.
- As the GM1200i offers up to 10 hours run time on a full tank at a 25% load, it falls within the average autonomy range among the inverter generators of a similar power. If concerned with autonomy, one of the products of a comparable power output, which offers the highest run time, is the DuroMax XP2300iH, boasting with up to 13 hours.
- Even though run times are undoubtedly important, they are dependent on the fuel capacity to a large extent. For a more wholesome picture, we must take into consideration the fuel consumption of the generator. This inverter generator can be considered as one of the most fuel efficient, due to its low estimated fuel consumption of only 0.07 GPH (gallon per hour) at 25% load, within the aforementioned wattage range.
Price comparison
As you can see from this interactive chart, 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.
