Power & Run Time

The Sportsman GEN4000DF

Thanks to its dual-fuel technology, the Sportsman GEN4000DF 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.

The generator features a standard recoil pull-rope starting mechanism. It is rated for a noise of 69 dBA (less noisy than background music).

With a fuel capacity of 3.6 gallons, the GEN4000DF can operate for around 10 hours at 50% load using gasoline (fuel consumption around 0.36 GPH), or for around 12 hours (on a 20 lbs tank - propane consumption around 0.39 GPH) using propane.

Outlets

The control panel features 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 providing easy battery charging capabilities.

Thanks to its TT-30R receptacle (TT stands for 'Travel Trailer'), this Sportsman generator is RV Ready, making it ideal for powering recreational vehicles.

Portability

Measuring L24.5 x W17 x H16.5 in, the Sportsman GEN4000DF showcases a classic open frame layout, offering stability and simple maintenance access to components, while facilitating air circulation. The design is ideal for rough environments and demanding outdoor use.

The 90 lbs of the GEN4000DF's dry weight enables you to use it anywhere you will ever need. Additionally, the generator’s mobility is enhanced by its open frame design, as it can be easily grabbed and shifted.

Features

The GEN4000DF's control panel

The GEN4000DF's status and activity may be monitored conveniently via the control panel, as it features a convenient voltmeter, which provides an easy way to monitor power output anytime.

As far as security is concerned, the generator can be used with a peace of mind, as it features an overload protection (circuit breaker) and an automatic low oil shut-off.

Beyond the standard documentation and an owner's manual (opens in a new tab) to assist with setup, the Sportsman GEN4000DF ships with supplementary accessories: battery charging cables, propane hose, funnel and tool kit.

The Sportsman GEN4000DF versus other generators

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

• At 90 lbs in dry weight, the Sportsman GEN4000DF fits well within the typical weight bracket for dual fuel generators producing 3000 to 4000 rated watts. Regarding dry weight, one of the champions in the same power range is the Champion 201050, with a dry weight of only 51.8 lbs.
• The generator's noise output, rated at 69 dBA, falls within the average range expected for devices in its type and power range. If you wish to prioritize minimal noise, the Westinghouse iGen5000DF stands out as one of the quietest options among generators of similar power, with a rating of 52 dBA.
• Regarding its autonomy, the autonomy of the GEN4000DF, reaching around 10 hours at a 50% load, can be considered as low end, compared to other dual fuel products of a roughly equal 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.
• 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. This generator has an average fuel consumption among comparably powerful devices, as it reaches 0.36 GPH (gallon per hour) at a 50% load. If you wish to acquire one of the most gasoline efficient products of this power range, the Westinghouse iGen5000DF, with a fuel consumption of 0.23 GPH could be in your good books.
