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. Moreover, the parallel capability (parallel kit 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.
The inverter generator is rated for a noise of 66 dBA (less noisy than background music). Its starting mechanism is based on a classic hand-operated recoil starting mechanism.
With its 2.24 gallons fuel tank, the GM3500Xi can operate for around 8.5 hours at 50% load when fully fueled (with fuel usage averaging around 0.26 GPH).
Sensitive electronics can be safely plugged in the AC outlets, as the GM3500Xi produces a clean sine wave, with a <5% Total Harmonic Distortion (THD).
Outlets
The control panel features the following 3 AC outlets:
Furthermore, it showcases 2 DC outlets: there's two 5V USB ports (USB-A) with which charging of electronics like mobile phones and tablets is made convenient.
While this Genmax generator is not RV Ready, its L5-30R receptacle can be used for a simple RV connection with an L5-30P to TT-30R adaptor.
Portability
With a size of L18.9 x W13.6 x H17.7 in, the Genmax GM3500Xi features an open frame design, providing stability and simplified maintenance access to components, enhancing air circulation. This type of design is ideal for tough environments and heavy outdoor use.
At 57.3 lbs, the GM3500Xi is easily managed, ensuring it can be brought along wherever you need power. Moreover, the open frame design of the generator simplifies grabbing and relocating it.
Features
The GM3500Xi's control panel
Included in the control panel of the GM3500Xi, a digital data center assists in tracking its status and activity by providing details on the lifetime run hours.
In addition to this info, the light indicators show you if its oil levels are insufficient, the generator is ready and the generator is overloaded.
As far as security is concerned, the generator can be used with a peace of mind, as it features an overload protection (circuit breaker) and an automatic low oil shut-off.
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 GM3500Xi also includes several accessories: tool kit and funnel.

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).
- Regarding its weight, the Genmax GM3500Xi only weighs in at 57.3 pounds, which means it's one of the lighter inverter generators in the 2500-3500 rated wattage range. If weight is a key factor for your needs, the Pulsar PGD40iSCO is noteworthy for being one of the top contenders in this power range, with a dry weight of 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 is a concern for you, you could consider the Honda EU3000iS, which is one of the least noisy generators in its power range, rated at 50 dBA.
- The GM3500Xi provides around 8.5 hours of runtime at a 50% load on a full tank, placing it within the average autonomy range among similar inverter generators. If autonomy is your priority, one of the devices of a similar power output with the highest run time is the Generac iQ3600DF, reaching around 13 hours.
- Even though run times are undoubtedly important, they are dependent on the fuel capacity to a large extent. For a more wholesome picture, we must take into consideration the fuel consumption of the generator. This inverter generator provides better fuel efficiency than most others in its wattage range, consuming approximately 0.26 GPH (gallon per hour) at 50% load. To prioritize fuel savings, we advise considering the Pulsar PGD40iSCO, which stands out for its gasoline efficiency, consuming just 0.22 gallons per hour.
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.
The bottom line
- Inexpensive
- CO DETECT technology
- Parallel capable
- Inverter
- Lightweight (57.3 lbs)
- Fuel efficient
- Decent run time
- 1-year warranty
- No electric start
- 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.
