Power & Run Time

The Sportsman GEN4000DF-SS

With its dual-fuel technology, the Sportsman GEN4000DF-SS delivers 120V, and offers power and flexibility. Running on gasoline, it boasts a running wattage of 3,500W and a peak wattage of 4,000W. When powered by propane, it delivers 3,100 running watts and 3,600 peak watts.

With a noise rating of 69 dBA (less noisy than a normal conversation), the generator features a traditional recoil pull-start mechanism.

In terms of its run time capability, the GEN4000DF-SS, furnished with a 3.9 gallons fuel tank, can maintain operations for around 10 hours at 50% load on a full tank of gasoline (with fuel consumption averaging 0.39 gallons per hour). It also provides around 12 hours (on a 20 lbs tank - propane consumption around 0.39 GPH) of operation with propane.

Outlets

The control panel provides the upcoming 5 AC outlets:

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

120V 30A (TT-30R) receptacle

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

Equipped with a TT-30R receptacle (TT representing 'Travel Trailer'), this Sportsman generator is RV Ready, ensuring compatibility with recreational vehicles.

Portability

At L23 x W19.5 x H17.5 in, the traditional open frame structure of the Sportsman GEN4000DF-SS ensures stability while facilitating convenient maintenance access to components and promoting air cooling. This type of design is ideal for tough environments and heavy outdoor use.

With a dry weight of 91 lbs, the GEN4000DF-SS is convenient, ensuring it can be taken wherever power is needed. Furthermore, the generator's open frame construction allows for easy grabbing and movement.

Features

The GEN4000DF-SS's control panel

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 your top priority, one of the champions in this power category is the Champion 201050, weighing just 51.8 pounds.
• With noise emissions reaching as low as 69 dBA, this generator has a noise level typical for devices of its type and power category. For those who are looking for a less noisy device, we suggest the Westinghouse iGen4000DFc. With just 52 dBA, it is one of the most quiet devices in this power range.
• 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. Furthermore, considering the run times, one of the generators which have a roughly same power output, with the highest autonomy, is the Westinghouse iGen5000DF, as it provides around 15 hours.
• Run time is a key metric, but it's dependent on the generator's fuel tank capacity. Therefore, discussing fuel efficiency is necessary for a complete understanding. In fact, this generator is not one of the most fuel-efficient options in the aforementioned wattage range: its estimated gasoline consumption at 50% load is around 0.39 GPH. If you wish to get a unit of similar power, but with one of the best fuel efficiency, you could consider the Westinghouse iGen5000DF, which has an impressively low fuel consumption of 0.23 GPH.
