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
- Camping and tailgating buffs looking to enhance their experience
In the sections ahead, the power characteristics, availability of various outlets, the portability, and any additional features of the device shall be discussed.
Power & Run Time
The Genmax GM3500Xi
The Genmax GM3500Xi is powered by a 145 cc (5.2 hp) Dinking OHV 4-stroke engine. It delivers 120V, runs on gasoline and offers a running wattage of 3,200W as well as a peak wattage of 3,500W. In addition, the device is parallel capable (parallel kit not included) and thus, can be linked to a similar or compatible unit for added power.
With a noise rating of 66 dBA (less noisy than a normal conversation), the inverter generator's starting mechanism is centered around a standard recoil pull-rope starting 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).
As the GM3500Xi produces a clean sine wave, with a <5% Total Harmonic Distortion (THD), sensitive electronics may be plugged in the AC outlets safely.
Outlets
The control panel includes 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.
This Genmax generator isn't quite RV Ready, but it features an L5-30R receptacle, allowing a simple RV connection through an L5-30P to TT-30R adaptor.
Portability
With dimensions of L18.9 x W13.6 x H17.7 in, the traditional open frame design of the Genmax GM3500Xi ensures stability while allowing easy maintenance access to components and promoting effective air cooling. The device has been designed for tough environments and demanding outdoor use.
With a dry weight of 57.3 lbs, the GM3500Xi is convenient, ensuring it can be taken wherever power is needed. Furthermore, thanks to its open frame, the generator is easily grabbed and moved to a new location.
Features
The GM3500Xi's control panel
Designed with a digital data center, the control panel of the GM3500Xi grants you access to crucial data on the lifetime run hours, ensuring practical monitoring of its status and activity.
In addition to this info, light indicators on the device will notify you if the generator is on overload, its oil levels are insufficient and the generator is ready.
From a security standpoint, the generator is furnished with an automatic low oil shut-off and an overload protection (circuit breaker), 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.
Along the basic documentation and an owner's manual (opens in a new tab), useful for starting the generator right away, the Genmax GM3500Xi's package also includes these accessories: tool kit and funnel.
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).
- As far as its dry weight is concerned, the Genmax GM3500Xi weighs just 57.3 pounds and thus, it is one of the lighter 2500 to 3500 rated wattage inverter generators. Weight-conscious users may find the Pulsar PGD40iSCO appealing, as it is one of the top contenders in this power range, weighing just 46 pounds.
- When comparing it to devices with a similar running wattage, this inverter generator's lowest noise level of 66 dBA puts it alongside the noisier units. 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.
- Offering around 8.5 hours of running time on a full tank at 50% load, the GM3500Xi is within the average autonomy range of similarly powerful inverter generators. Furthermore, considering the run times, one of the generators which have a roughly same power output, with the highest autonomy, is the Ryobi RYi4022X, as it provides around 12 hours.
- Though run time is a significant parameter, it's closely tied to the generator's fuel tank size. To get a comprehensive understanding, fuel efficiency must also be taken into account. 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.

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.
