Description
Zoom on the Genmax GM3500Xi
In summary, the Genmax GM3500Xi is a compact and lightweight portable inverter generator especially useful for:
- RV travellers wishing to enhance their freedom and nomad lifestyle
- Occasional participants of outdoor events, competitions, concerts and festivals
- DIYers who wish to improve their efficiency with tools
- Homeowners who want to be able to use the most necessary devices in their household, even during a blackout
- Tailgating and campground aficionados with the desire of enjoying power anywhere they go
In the following paragraphs, we shall explore the power characteristics, available outlets, portability, and any additional features of the device.
Power & Run Time
The Genmax GM3500Xi
Genmax GM3500Xi runs on gasoline, powered by a 145 cc (5.2 hp) Dinking OHV 4-stroke engine, delivering 120V, boasting a running wattage of 3,200W alongside a starting wattage of 3,500W. Moreover, the parallel capability (parallel kit not included) allows for increasing of power output when paired with another similar or compatible unit, providing increased energy capacity and reliability for diverse needs.
Enjoying a noise rating of 66 dBA (less noisy than a normal conversation), this inverter generator gets running thanks to a traditional recoil pull-start mechanism.
The GM3500Xi's fuel tank, boasting 2.24 gallons, allows it to operate for around 8.5 hours at 50% load with a full tank (with an estimated fuel consumption of 0.26 GPH).
The GM3500Xi generates a clean sine wave with <5% Total Harmonic Distortion (THD), ensuring minimal electrical noise and fluctuations. This feature makes it ideal for powering sensitive electronics, providing stable and reliable AC power through the outlets.
Outlets
The control panel features the following 3 AC outlets:
Furthermore, it showcases 2 DC outlets: there's two 5V USB ports (USB-A) ideal for charging various electronic devices such as smartphones and tablets.
Despite not meeting the 'RV Ready' criteria, this Genmax generator grants the advantage of simple RV compatibility via its L5-30R receptacle, enabling you to conveniently power your RV by using an L5-30P to TT-30R adaptor.
Portability
Measuring L18.9 x W13.6 x H17.7 in, the classic open frame build of the Genmax GM3500Xi delivers stability and easy maintenance access to components, facilitating air circulation. The featured design is ideal for the outdoors and all tough environments.
At 57.3 lbs, the GM3500Xi is easily managed, ensuring it can be brought along wherever you need power. Moreover, its open frame design makes it incredibly easy to grasp the frame in order to change its location.
Features
The GM3500Xi's control panel
One of the many GM3500Xi's features is the digital data center, included in its control panel, which conveniently provides information on the lifetime run hours and thus, helps you monitor its activity and status.
In addition to this info, several light indicators serve to show you when the generator is ready, the generator is overloaded and its oil levels are insufficient.
From a security standpoint, the generator is furnished with an overload protection (circuit breaker) and an automatic low oil shut-off, ensuring peace of mind during operation.
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 GM3500Xi also comes with some accessories: funnel and tool kit are included.
Product Videos
The Genmax GM3500Xi versus other generators
The following charts are provided to give you an idea of how some of the key specs of the Genmax GM3500Xi compare to inverter generators of similar power (between 2500 and 3500 W).
- Considering its weight, the Genmax GM3500Xi registers at a modest 57.3 pounds, placing it among the lighter inverter generators in the 2500 to 3500 rated wattage selection. Regarding dry weight, one of the champions in the same power range is the Pulsar PGD40iSCO, with a dry weight of only 46 lbs.
- This inverter generator, with its lowest noise level at 66 dBA, is noisier than most generators of comparable running wattage. If noise emissions are important to you, one of the least noisy generators of this power range is the Honda EU3000iS with only 50 dBA.
- The GM3500Xi, falls within the average autonomy range compared to inverter generators of a roughly same power, with a run time of around 8.5 hours at a 50% load and a full tank. For those prioritizing autonomy, the Generac iQ3600DF could be considered, as it offers one of the longest run times among generators with similar power output, reaching around 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. At an estimated fuel consumption of 0.26 GPH (gallon per hour) at 50% load, this inverter generator is a rather fuel-efficient one within its wattage category. If you wish to get a unit of similar power, but with one of the best fuel efficiency, you could consider the Pulsar PGD40iSCO, which has an impressively low fuel consumption of 0.22 GPH.
Price comparison
As you can see from these interactive charts, when compared to other 2500-3500W inverter generators, the Genmax GM3500Xi 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.

- CO DETECT technology
- Parallel capable
- Inverter
- Lightweight (57.3 lbs)
- Fuel efficient
- Decent run time
- No electric start
- 1-year warranty
- On the noisy side (66 dBA)

User Reviews
This unit would be nice if they used better quality parts, had parts and service available in the USA. It had wiring routing problems, and inverter cover that was pinched where it splits, not easy to get to the spark plug, and carburetor vent hoses that were cut off at the carburetor upon opening. I just can’t recommend this generator.
