The Sportsman GEN3500DFi has 120V and a lot of power and versatility thanks to its dual-fuel technology. When powered by gasoline, it has a running wattage of 3,000W and a maximum wattage of 3,500W. When run by propane, it has a rated power of 2700 watts and a peak power of 3150 watts. Also, since it can work in parallel (but doesn’t come with a parallel kit), its power can be doubled by connecting it to a second unit that works with it. This inverter generator has a noise level of 69 dBA, which is less loud than background music. It starts up with a traditional pull-start mechanism. With a full tank of gasoline, the GEN3500DFi, which has a fuel capacity of 3.2 gallons, can run for about 10 hours at half load (fuel consumption is approximately 0.32 GPH). It can run for about 12 hours if propane is used (on a 20 lbs tank – propane consumption around 0.39 GPH). As the GEN3500DFi 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.
On the control panel, there are 3 AC outlets: a duplex 120V 20A (5-20R) outlet and a 120V 30A (TT-30R) outlet.It also has 2 DC outlets: a 12V 8A receptacle for charging batteries and a 5V USB port for charging devices like cell phones and tablets.The TT-30R plug on this Sportsman generator is ready for an RV.TT stands for “Travel Trailer”.
Some lights let you know right away if the generator doesn’t have enough oil, if it’s ready to go, or if it’s overloaded.As for safety features, the device has a circuit breaker for overheating and an automatic shut-off for low oil, so you can use it without worry.The Sportsman GEN3500DFi comes with a tool kit, propane hose, battery charging cables, and a funnel, as well as the usual paperwork and an owner’s manual to get you up and running quickly.
Since the Sportsman GEN3500DFi is an inverter generator, its enclosed design (L21.5 x W16.1 x H18.3 in) looks better than a traditional open frame product.The generator has a modern look and is easy to use when generating power for fun.With a dry weight of only 83 pounds, the GEN3500DFi can go with you wherever you need power.Also, shifting it is easy because the GEN3500DFi has a clever double handle that makes it much easier to hold.
The following charts show how some of the most important features of the Sportsman-GEN3500DFi compare to other generators with the same power output.

- 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.
