Power & Run Time

The Sportsman GEN4000DF-SS

Thanks to its dual-fuel technology, the Sportsman GEN4000DF-SS provides a 120V output and offers both versatility and power. When utilizing gasoline, it delivers a running wattage of 3,500W and a starting wattage of 4,000W. Alternatively, when operating on propane, it provides 3,100 running watts and 3,600 starting watts.

Operating at a noise rating of 69 dBA (less noisy than an office), this generator starts up with a classic hand-operated recoil starting mechanism.

As for its running time, the GEN4000DF-SS, along with its 3.9 gallons fuel capacity, can run for around 10 hours at 50% load with a full tank filled with gasoline (fuel consumption around 0.39 GPH). If propane is used, it can operate for around 12 hours (on a 20 lbs tank - propane consumption around 0.39 GPH).

Outlets

The control panel provides the upcoming 5 AC outlets:

Two Duplexes 120V 20A (5-20R)

120V 30A (TT-30R) receptacle

Additionally, it offers 1 DC outlet: there's a 12V 8A receptacle with which charging your batteries is made easy.

Thanks to its TT-30R receptacle (TT stands for 'Travel Trailer'), this Sportsman generator is RV Ready.

Portability

With a size of L23 x W19.5 x H17.5 in, the Sportsman GEN4000DF-SS features an open frame design, providing stability and simplified maintenance access to components, enhancing air circulation. The device has been designed for tough environments and demanding outdoor use.

The 91 lbs of the GEN4000DF-SS's dry weight enables you to use it anywhere you will ever need. Moreover, its open frame design makes it incredibly easy to grasp the frame in order to change its location.

The Sportsman GEN4000DF-SS versus other generators

The following charts are provided to give you an idea of how some of the key specs of the Sportsman GEN4000DF-SS compare to dual fuel generators of similar power (between 3000 and 4000 W).

• With a dry weight of 91 pounds, the Sportsman GEN4000DF-SS finds itself in the expected weight range for dual fuel generators able to produce between 3000 and 4000 rated watts. If weight is a key factor for your needs, the Champion 201050 is noteworthy for being one of the top contenders in this power range, with a dry weight of 51.8 pounds.
• Given its rated noise level of 69 dBA, this 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 Westinghouse iGen5000DF, whose lowest noise levels reach just 52 dBA.
• As far as autonomy is concerned, providing around 10 hours of runtime with a full tank at a 50% load, the GEN4000DF-SS falls into the low end in comparison with other dual fuel devices of a comparable power output. If you wish to prioritize autonomy, the Westinghouse iGen5000DF shines as one of the top contenders, offering one of the highest run times among generators with similar power output, totaling around 15 hours.
• While the run time is an important parameter, it is dependent on the fuel tank's capacity and thus, doesn't say much on its own unless we consider fuel consumption as well. This generator is rather wasteful, compared to other devices within the aforementioned output range, when it comes to gasoline consumption, as it reaches roughly 0.39 GPH at a 50% load. If fuel consumption is your top priority, we suggest to check out the Westinghouse iGen5000DF, which has a fuel consumption of only 0.23 GPH and thus, is one of the most efficient devices in our database.
