Power & Run Time
The Genmax GM3500iAED
Delivering 120V, the Genmax GM3500iAED is enhanced by dual-fuel technology, providing power and versatility. Running on gasoline, it boasts a running wattage of 3,200W and a starting wattage of 3,500W. Alternatively, when propane-powered, it delivers 2,800 running watts and 3,100 starting watts. Moreover, the parallel capability (parallel kit (opens in a new tab) 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.
The inverter generator, rated for a noise of 62 dBA (just slightly more noisy than background music), provides flexibility in starting, offering both a classic hand-operated recoil starting mechanism and a no-fuss and convenient electric starter (battery included). The GM3500iAED can also be remotely started, offering further convenience (key fob included).
The GM3500iAED, with a fuel capacity of 1.7 gallon, reaches a run time of up to 8 hours utilizing gasoline (fuel consumption around 0.21 GPH). Alternatively, it can reach a run time of up to 16 hours (estimation based on a 20 lbs tank - propane consumption around 0.29 GPH) with propane.
The <3% Total Harmonic Distortion (THD) of the GM3500iAED ensures a clean sine wave output, providing a secure power source for your sensitive electronics through its AC outlets.
Outlets
The control panel features the following 3 AC outlets:
Additionally, it features 2 DC outlets: there's two 5V USB ports (USB-A) perfect for conveniently charging mobile phones, tablets, and other electronic devices.
Despite not having the 'RV Ready' status, this Genmax generator provides the benefit of convenient RV compatibility through its L5-30R receptacle, enabling you to easily power your RV using an L5-30P to TT-30R adaptor (included).
Portability
With its enclosed inverter generator design (L20.9 x W12.2 x H19.7 in), the Genmax GM3500iAED offers superior aesthetics and operates with minimized noise levels, distinguishing itself from standard, open frame generators. The featured design follows the latest trends and is ideal for easy and recreational use.
With a dry weight of 56.2 lbs, the GM3500iAED can easily follow you wherever your power needs are. Additionally, its set of 2 wheels (⌀4") and its telecospic handle will allow for simple relovation of the generator once it's on the ground.
Features
The GM3500iAED's control panel
For easy status and activity monitoring of the GM3500iAED, its control panel integrates a digital data center, offering insights into the power output, frequency, voltage, lifetime run hours and fuel level.
In addition to this info, when the generator is ready, the generator is on overload and the oil level is too low, you will be informed by the featured light indicators.
Regarding security, the generator comes with an automatic low oil shut-off and an overload protection (circuit breaker), providing 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.
Alongside the standard documentation and an owner's manual (opens in a new tab) for quick setup, the Genmax GM3500iAED is bundled with additional accessories: tool kit, propane hose, RV adapter, funnel and key fob.
Product Videos
The Genmax GM3500iAED versus other generators
The following charts are provided to give you an idea of how some of the key specs of the Genmax GM3500iAED compare to inverter generators of similar power (between 2500 and 3500 W).
- As far as its dry weight is concerned, the Genmax GM3500iAED weighs just 56.2 pounds and thus, it is one of the lighter 2500 to 3500 rated wattage inverter generators. If weight is your top priority, one of the champions in this power category is the Pulsar PGD40iSCO, weighing just 46 pounds.
- Given its rated noise level of 62 dBA, this inverter generator aligns with the average expected noise rating for devices 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 Honda EU3000iS, whose lowest noise levels reach just 50 dBA.
- In terms of autonomy, the GM3500iAED offers up to 8 hours at a 25% load, placing it at the lower range within its type and power range. If run time is one of your main concerns, the Champion 200977 could be worth looking at. It boasts one of the highest run times among units of comparable power, lasting 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. This inverter generator is not fuel-efficient compared to devices of similar output: its estimated fuel consumption stands at 0.21 GPH at a 25% load. If fuel consumption is your top priority, we suggest to check out the Energizer eZV3500P, which has a fuel consumption of only 0.13 GPH and thus, is one of the most efficient devices in our database.
Price comparison
As you can see from these interactive charts, when compared to other 2500-3500W dual fuel inverter generators, the Genmax GM3500iAED is on the average side of the price range.
Therefore, this generator nicely fits in the expected budget for this kind of product.

User Reviews
I ordered this with subdued expectations. It is not a Honda so I expected expected half the performance for paying less than half the price. Worked right out of the box for me. Quality build (similar to Yamaha). Ran for one hour then changed oil… this is highly recommended as there were alot of metal flakes. Changed oil again after 2nd hour under 25% load… no metal flakes. Running on only propane so far. Have tested it at PEAK and both 50% and 80% running load. Very little noise difference. This is where I usually like to run the generator. If I need more power I will use gas instead of LP. LAck of 30A plug is not really a big deal as an adapter comes with the unit. In terms of usage for a travel trailer I find this all around easier and a bit better than the Predator 3500. Lighter, quieter, easier to move…
I purchased this inverter generator and it wouldn’t run straight out the box. Obviously, I didn’t mean I took it out the box and tried to run it. The proper amount of oil and fuel was put in it and the battery cable was connected. It would crank, but only run for a few seconds then the overload light would come on. Even with it cranking, it seemed to only run at a fraction of it’s ability. Then the CO2 light flashed, which the label states it needs maintenance. Don’t know what happened to QC at this company, but this unit DEFINITELY wasn’t checked, prior to shipping.
Several quality control issues right out of the box and also a very dangerous flaw with this machine. I’ve done many reviews and helped re-engineer some. This had poor wire routings, engine shakes bad at idle, changing oil you have to tip to the side to drain. Doing so leaks gas out of the tank vent and it fills the air filter box with gas which then runs out back by a hot muffler…no kidding. GenMax offered a warning sticker to fix this dangerous flaw. These could be such good machines if they used quality parts and had parts and service in the USA. I highly can’t recommend at all.
