Description
Zoom on the Genmax GM10500iETC
In a nutshell, the Genmax GM10500iETC is a powerful portable inverter generator mostly geared towards homeowners who want to be sure of their ability to power their fridges, cooking tools, heating and lighting equipment during power failures.
The subsequent sections will explore in detail its power characteristics, the diverse outlets it provides, its overall portability, and the supplementary features it offers.
Power & Run Time
The Genmax GM10500iETC delivers 120/240V and boasts with a tri-fuel technology enabling it to utilize gasoline, propane, or natural gas. When powered by gasoline, it achieves a running wattage of 8,500W and a peak wattage of 10,500W. Upon using propane, it gains 8,000 rated watts and 9,500 peak watts. Its operation with natural gas provides 6,800W of rated wattage and 8,400W of starting wattage. Moreover, the parallel capability (GM9000PK parallel kit (opens in a new tab) not included) enables power output to increase when paired with another similar or compatible unit, providing increased energy capacity and versatility for a wide range of needs.
At a noise rating of 64 dBA (just slightly more noisy than an office), this inverter generator can be started via a conventional pull-start mechanism, or a convenient and efficient electric starter (battery included). To increase convenience, the GM10500iETC offers remote starting functionality, allowing for easy operation from a distance (key fob included).
With a fuel capacity of 6.9 gallons, the GM10500iETC can operate for up to 14 hours using gasoline (fuel consumption around 0.49 GPH), or for up to 7 hours (estimation based on a 20 lbs tank - propane consumption around 0.67 GPH) using propane.
Sensitive electronics can be safely plugged in the AC outlets, as the GM10500iETC produces a clean sine wave, with a <3% Total Harmonic Distortion (THD).
Outlets
The control panel provides the upcoming 6 AC outlets:
Furthermore, it showcases 1 DC outlet: there's a 12V 8A (cigarette lighter style) receptacle making battery charging a breeze.
The GM10500iETC's twist-lock L14-30R receptacle makes it transfer switch ready, enabling hassle-free connection to your breaker box for powering your home during outages. The unit also features an ATS plug, which makes it compatible with automatic transfer switches.
Portability
As the Genmax GM10500iETC is an inverter generator, its encased design (L30.9 x W22.6 x H29.3 in) offers more aesthetics than a conventional, open frame product. This type of design is the most modern and convenient way to recreationally generate power.
Even though this device may be technically portable (as in movable), manipulation and transportation without special equipment can be a challenge, as it weighs 244.7 pounds. Despite the restricted maneuverability, its set of 2 wheels and its folding handle provides a solution, allowing for convenient shifting once the generator is positioned on the ground.
Features
Featuring a digital data center on its control panel, the GM10500iETC offers you convenient access to essential information about the power output, voltage, lifetime run hours and frequency, facilitating effective monitoring of its activity and status. To offer you even more control and easy operation during nighttime, the panel is LED-lit.
In addition to this info, some light indicators allow you to instantly see if the generator is on overload, its oil levels are insufficient and the generator is ready.
The fuel level of the inverter generator can be determined quickly, easily, and conveniently with the help of its built-in fuel gauge.
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.
In addition to the traditional documentation and an owner's manual (opens in a new tab) to help you get started promptly, the Genmax GM10500iETC also includes several accessories: propane hose, neutral bonding plug, funnel, RV adapter, battery charger, natural gas hose with NPT adapter, cover, key fob and tool kit.

The Genmax GM10500iETC versus other generators
The following charts are provided to give you an idea of how some of the key specs of the Genmax GM10500iETC compare to multi-fuel generators of similar power (between 8000 and 9000 W).
- A weight of 244.7 lbs makes the Genmax GM10500iETC one of the heavier multi-fuel devices in the 8000-9000 rated wattage range. if you wish to prioritize weight, the Pulsar PGL9000BCO is one of the top contenders in its power category, weighing only 149 pounds.
- With a lowest noise rating of 64 dBA, the inverter generator is one of the more quiet of the generators of similar type and power. If you’d prefer a less noisy device, one of the most quiet devices, which share the same power range with this one, is the DuroMax XP11000iH, whose lowest noise levels reach just 61 dBA.
- As for its runtime, the GM10500iETC runs for up to 14 hours at a 25% load, placing it towards the low end among comparable multi-fuel products. 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 XP10000EH, with up to 22 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. In terms of fuel efficiency within its wattage range, this inverter generator falls short: it consumes approximately 0.49 GPH at a 25% load. If you wish to acquire one of the most gasoline efficient products of this power range, the DuroMax XP10000EH, with a fuel consumption of 0.38 GPH could be in your good books.
Price comparison
As you can see from these interactive charts, when compared to other 8000-9000W multi-fuel generators, the Genmax GM10500iETC is on the expensive side of the price range.
While certainly not the cheapest of its kind, purchasing it would most likely also mean enjoying the reliability of a high-end product.
