- RV travellers looking for even more independence
- DIYers who wish to improve their efficiency with tools
- Homeowners who want to be able to use the most necessary devices in their household, even during a blackout
The following sections will present you in detail its power characteristics, the different outlets it offers, its overall portability, the extra features it benefits from and any relevant emission compliance details.
Power & Run Time
The dual-fuel technology of the Sportsman GEN4000DF-SS allows for an output of 120V and provides superb power and versatility. If gasoline-powered, the device provides a running wattage of 3500W and a starting wattage of 4000W. If propane-powered, it gives 3100 rated watts and 3600 starting watts.
Enjoying a noise rating of 69 dBA (less noisy than background music), this generator gets running thanks to a conventional pull-start mechanism.
Regarding its running time, the GEN4000DF-SS, with a 3.9 gallons fuel capacity can operate for around 10 hours at 50% load with a full tank of gasoline (fuel consumption around 0.39 GPH). When using propane, it can run for around 12 hours (on a 20 lbs tank - propane consumption around 0.39 GPH).
The control panel features the upcoming 5 AC outlets:
In addition, it provides 1 DC outlet: there's a 12V 8A receptacle allowing you to easily charge your batteries.
This Sportsman generator is RV Ready, as it features a TT-30R receptacle (TT stands for 'Travel Trailer').
The Sportsman GEN4000DF-SS has the following dimensions: L23 x W19.5 x H17.5 in. In combination with its conventional, open frame design, they provide support and allow the generator to be raised above ground level. The featured design is ideal for the outdoors and all tough environments.
The GEN4000DF-SS can be taken anywhere with you, thanks to its weight of 91 lbs. Additionally, the generator’s mobility is also improved by its open frame design, as it can be easily grabbed and displaced.
As for its security measures, the device features an overload protection (circuit breaker) and an automatic low oil shut-off, letting you use it with a peace of mind.
With the basic documentation and a user manual, letting you start the generator quickly, the Sportsman GEN4000DF-SS also comes with several accessories, including: tool kit, funnel, propane hose and battery charging cables.
The Sportsman GEN4000DF-SS is EPA approved, but NOT CARB-compliant. Thus, it cannot be purchased or sold in California.
Moreover, it features a spark arrestor and thus, may be used in forested areas.
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 generators of similar power (between 3000 and 4000 W).
- Weight-wise, the Sportsman GEN4000DF-SS has only 91 lbs, which renders it one of the lighter generators which produce 3000 to 4000 rated watts. In terms of weight, one of the champions in their power range is the WEN GN400i, standing at just 66.1 lbs.
- This generator, with its lowest possible noise rated at 69 dBA falls into the more noisy category, compared to other devise of a similar running wattage. If noise emissions are important to you, one of the least noisy generators of this power range is the Westinghouse iGen4500 with only 52 dBA.
- Regarding its autonomy, the autonomy of the GEN4000DF-SS, reaching around 10 hours at a 50% load, can be considered as low end, compared to other products of a roughly equal output. If concerned with autonomy, one of the products of a comparable power output, which offers the highest run time, is the Honda EB4000, boasting with around 16 hours.
- Even though run times are undoubtedly important, they are dependent on the fuel capacity to a large extent. For a more wholesome picture, we must take into consideration the fuel consumption of the generator. In fact, this generator is not among the most fuel efficient, within the aforementioned wattage range : its estimated gasoline consumption at 50% load is around 0.39 GPH. If you wish to further improve in the area of fuel efficiency, the Westinghouse iGen4200, which boasts with a gas consumption of only 0.17 GPH, may be the right generator for you.
As you can see from this dynamic chart, when compared to other 3000-4000W generators, the Sportsman GEN4000DF-SS is on the average side of the price range.
Therefore, this generator nicely fits in the expected budget for this kind of product.
