Description
The Genmax GM3500Xi has a gasoline-powered Dinking OHV 4-stroke engine with 145 cc and 5.2 hp. It has a 120V output and a running power of 3,200W and a peak power of 3,500W. Also, since it can work in parallel (but doesn’t come with a parallel kit), its power can be increased by connecting it to a second unit that works with it. This inverter generator has a noise level of 66 dBA, which is quieter than background music. It starts up with a traditional pull-start. With a full tank, the GM3500Xi can run for about 8.5 hours at 0.5 load (using about 0.26 GPH of fuel). This is because it can hold 2.24 gallons of fuel. As the GM3500Xi makes a clean sine wave with a Total Harmonic Distortion (THD) of less than 5%, you can safely plug sensitive electronics into the AC outlets.
Outlets
On the control panel, there are 3 AC outlets: a duplex 120V 20A (5-20R) outlet and a 120V 30A (L5-30R) outlet. It also has 2 DC outlets: there are two 5V USB ports (USB-A) that make it easy to charge devices like cell phones and tablets. Even though this Genmax generator isn’t quite RV Ready, an L5-30P to TT-30R adapter makes it easy to connect it to an RV.
Features
The GM3500Xi’s status and activity can be tracked with the help of a digital data center, which is part of the control panel and shows how many hours the machine has been running for its whole life. In addition to this information, some lights let you know right away if the generator is ready, if it is overloaded, or if it doesn’t have enough oil. When it comes to safety, this product has an automatic low oil shut-off and an overload protection (circuit breaker), so you can use it without worry. It also has the CO DETECT technology from Genmax, which checks the amount of carbon monoxide in the air while the generator is running. If the generator isn’t set up right and carbon monoxide levels get too high, the generator will turn off by itself. It’s a nice extra safety measure, but don’t forget to take your generator outside at all times. The Genmax GM3500Xi comes with the standard paperwork and an owner’s manual, which will help you get the device up and running quickly. A tool kit and funnel are also included.
Mobility
The Genmax GM3500Xi is 18.9 inches long, 13.6 inches wide, and 17.7 inches high. Together with its traditional, open-frame design, they support the generator and allow it to be raised above the ground. The design works well in rough places and for hard outdoor use. With a dry weight of 57.3 lbs, the GM3500Xi’s power can be used anywhere. Also, the open frame makes it very easy to grab the frame and move it.

- We compared more than 500 portable generators at 50% load. We found that there is “skewed right” distribution for the difference between 50% load and 25% load and the median comes at 1.43. With this number we converter all the 25% load runtime to 50% load. Same with the propane efficiency, where median is 1.38.
- For some generators where propane runtime was not given, we used NIST 1994 GGE (Gasoline Gallon Equivalent) formula: 5.66 lbs. of propane = 1 gal of gasoline. All propane runtime is for 20 lbs. propane tank (4.7 gallons).
- Unlike many other sites, we actually tried to find out information about each of the above requirements. However, we are human and are therefore capable of the odd oversight or mistake. Please let us know if you spot any missing or erroneous values so that we can fix them.
