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
- 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 GM1200i
Genmax GM1200i is equipped with a 57 cc Dinking OHV 4-stroke engine, running on gasoline and providing 120V, boasting a running wattage of 1,000W alongside a starting wattage of 1,200W. Furthermore, its parallel capability (parallel kit included) allows power output to double when connected to another similar or compatible unit, ensuring expanded energy capacity and reliability for various applications.
With a noise rating of 58 dBA (less noisy than rainfall), the inverter generator's starting mechanism is centered around a manual recoil starter system.
With its 0.7 gallon fuel tank, the GM1200i can operate for up to 10 hours when fully fueled (with fuel usage averaging around 0.07 GPH).
Sensitive electronics can be safely plugged in the AC outlets, as the GM1200i produces a clean sine wave, with a <3% Total Harmonic Distortion (THD).
Outlets
The control panel features the following 2 AC outlets:
Furthermore, it has 2 DC outlets: there's two 5V USB ports (USB-A) designed for hassle-free charging of various electronic devices such as smartphones and tablets, ensuring uninterrupted usage.
Portability
Thanks to its closed inverter generator design (L16.5 x W9.5 x H15.7 in), the Genmax GM1200i not only offers superior aesthetics but also operates with reduced noise levels compared to a typical, open frame generator. The generator has a contemporary design, convenient for recreationally generating power.
The GM1200i boasts a weight of merely 25.3 lbs, solidifying its reputation as a lightweight, easily transportable generator. The device can be easily moved by just one person and thus, its power may be enjoyed on-the-go. This convenience is further enhanced by its handle (molded in the case), which allows for easy carrying.
Good to know: This unit ranks 4th in our list of the 10 smallest portable generators.
Features
The GM1200i's control panel
The device’s light indicators will display if its oil levels are insufficient, the generator is on overload and the generator is ready.
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 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. In terms of weight, one of the champions in their power range is the Pulsar PGD16iSCO, standing at just 24 lbs.
- Given its rated noise level of 58 dBA, this inverter generator aligns with the average expected noise rating for devices of similar type and power. 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.
- Offering up to 10 hours of running time on a full tank at 25% load, the GM1200i is within the average autonomy range of similarly powerful inverter generators. If run time is one of your main concerns, the DuroMax XP2300iH could be worth looking at. It boasts one of the highest run times among units of comparable power, lasting 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. Among devices of similar power, this inverter generator has one of the best fuel efficiency, with consumption rates of around 0.07 GPH (gallon per hour) at 25% load.
The bottom line
- CO DETECT technology
- Parallel kit included
- Inverter
- Lightweight (25.3 lbs)
- Fuel efficient
- Acceptable noise (58 dBA)
- Decent run time
- No data center
- 1-year warranty
