Power & Run Time

The Genmax GM3500Xi in use

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. Additionally, as the generator is parallel capable (parallel kit not included), it can be linked to a second unit for more power.

Enjoying a noise rating of 66 dBA (less noisy than an office), this inverter generator gets running thanks to a conventional pull-start mechanism.

With a full tank, the GM3500Xi can operate for around 8.5 hours at 50% load (fuel consumption around 0.26 GPH), thanks to its fuel capacity of 2.24 gallons.

Delicate electronics can be plugged in an AC outlets safely, as the GM3500Xi generates a clean sine wave, reaching a <5% Total Harmonic Distortion (THD).

Outlets

The control panel features the following 3 AC outlets:

Duplex 120V 20A (5-20R)
120V 30A (L5-30R) receptacle

Furthermore, it has 2 DC outlets: there's two 5V USB ports (USB-A) with which you may charge electronics, for example mobile phones or tablets, conveniently.

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

The Genmax GM3500Xi has a conventional, open frame design, of the following dimensions: L18.9 x W13.6 x H17.7 in, which offers support and allows it to be raised above ground level. This type of design is ideal for tough environments and heavy outdoor use.

The GM3500Xi can be taken anywhere with you, thanks to its weight of 57.3 lbs. Moreover, its open frame design makes it incredibly easy to grab the frame in order to change its location.

Features

The GM3500Xi's control panel

Monitoring of the GM3500Xi's status and activity is made possible by a digital data center, which provides information on the lifetime run hours and is one of the features of its control panel.

In addition to this info, some light indicators allow you to instantly see if its oil levels are insufficient, the generator is on overload and the generator is ready.

As for its security measures, the device features an overload protection (circuit breaker) and an automatic low oil shut-off, letting you use it with a peace of mind.

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.

While the standard documentation and an owner's manual (opens in a new tab), helpful for starting the device promptly, come with the Genmax GM3500Xi, the following accessories are also included: funnel and tool kit.

Emissions

The Genmax GM3500Xi is EPA approved, but NOT CARB-compliant. Thus, it cannot be purchased or sold in California.

However, it features a spark arrestor, making it usable in forested areas.

In addition, the unit meets the ANSI/PGMA G300-2018 safety and performance requirements.

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. If weight matters to you, one of the champions in this power range is the Pulsar PGD40iSCO with only 46 pounds.
  • As this inverter generator has its lowest possible noise of 66 dBA, it should be considered noisier compared to its peers of a comparable running wattage. If noise emissions are one of your priorities, you may be interested in the Honda EU3000iS, one of the least noisy generators similarly powerful as this one, rated for 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. Concerning the run times, one of the several devices with a comparable output, offering the highest autonomy, is the Ryobi RYi4022X, which is able to run for around 12 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. 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 further improve in the area of fuel efficiency, the Pulsar PGD40iSCO, which boasts with a gas consumption of only 0.22 GPH, may be the right generator for you.

Price comparison

As you can see from this interactive chart, 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.

    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.

    + PROS:
    • Compact, easy to change oil, fairly quiet,
    - CONS:
    • No parts or service available in USA, have to pull gas tank to get to spark plug, cheap parts used, wiring routed poorly.
