Zoom on the Genmax GM1200i
In summary, the Genmax GM1200i 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
- 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's engine, 57 cc Dinking OHV 4-stroke, fueled by gasoline, can deliver 120V. It provides a running wattage of 1000W and reaches a peak wattage of 1200W. Moreover, since it is parallel capable (parallel kit included), its power may be doubled if linked to a second compatible unit.
Enjoying a noise rating of 58 dBA (less noisy than a conversation at home), this inverter generator gets running thanks to a simple traditional pull-start mechanism.
The GM1200i can operate for up to 10 hours with a full tank (fuel consumption around 0.07 GPH), due to its fuel capacity of 0.7 gallon.
As the GM1200i produces a clean sine wave, with a <3% Total Harmonic Disruption (THD), sensitive electronics may be plugged in the AC outlets safely.
The control panel provides the upcoming 2 AC outlets:
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.
Thanks to its closed inverter generator design (L16.5 x W9.5 x H15.7 in), the Genmax GM1200i, is more esthetical than a typical, open frame generator. This modern design aims to provide an ideal power solution to recreational users.
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. 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.
When the generator is ready, the generator is on overload and the oil level is too low, you will be informed by the featured light indicators.
From a security point of view, the generator is equipped with an overload protection (circuit breaker) and an automatic low oil shut-off, giving you a peace of mind during use.
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. It’s a welcomed additional security feature, but don’t forget to always take your generator outside (opens in a new tab).
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: tool kit, funnel and RV adapter are included.
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 and thus, may be used in forested areas.
In addition, the unit meets the ANSI/PGMA G300-2018 safety and performance requirements.
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).
- As far as its dry weight is concerned, the Genmax GM1200i weighs just 25.3 pounds and thus, it is one of the lightest 1000 to 2000 rated wattage inverter generators.
- When compared to devices able to produce a similar running wattage, this inverter generator and its lowest emitted noise of 58 dBA is on the noisier side. For those who are looking for a less noisy device, we suggest the Honda EU2200i. With just 48 dBA, it is one of the most quiet devices in this power range.
- The GM1200i, falls within the average autonomy range compared to inverter generators of a roughly same power, with a run time of up to 10 hours at a 25% load and a full tank. If you consider autonomy on a single full tank as one of the deciding factors, one of the generators in the same power range that offers the highest run time is the DuroMax XP2300iH, with up to 13 hours.
- The run time is important, but also hugely depends on the capacity of the fuel tank and doesn't mean much if we don't talk about fuel consumption as well. This inverter generator, with an estimated fuel consumption of just 0.07 GPH (gallon per hour) at 25% load, is one of the most fuel efficient generators, for the previously mentioned wattage range.
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.
