Our top rated Sportsman generator and one of the best portable generators on the market today, the Sportsman GEN4000 offers exceptional power output, superior performance, amazing outlet options, and great runtime, all in an affordable, convenient package. The Sportsman GEN4000 can provide up to 4,000 watts of power and is powered purely by gasoline.

The fact that propane isn’t an option with the Sportsman GEN4000 might be seen as a slight disadvantage in the eyes of some shoppers, but gasoline is readily available and highly affordable too, so it should be a sufficient option for most people. Plus, the effectiveness of the Sportsman GEN4000 is second to none, with its 7 HP 4-Stroke OHV engine able to run for 10 hours on a full tank of gas at 1/2 load.

The Sportsman GEN4000 is a reasonably quiet Sportsman generator too, running at just 69 dB, and it’s not the lightest, but not too heavy either, weighing in at 91 lbs. It comes with a relatively short 1-year limited warranty, which is a little disappointing, but it’s a powerful all-round generator that shouldn’t cause you any problems. It also comes equipped with quite a few different outlet options, providing plenty of flexibility in terms of the devices you can use it with.

  • The perfect all-round Sportsman generator
  • 4,000 watts of power
  • Great runtime at half load
  • Impressive outlet options provide plenty of versatility
  • Quite a quiet machine
  • Relatively portable and not too heavy
  • Gasoline only
  • Short warranty

Sportsman GEN4000DFCBest Dual Fuel Generator

  • Type: Conventional
  • Peak/rated watts: 4000/3500 Gasoline; 3600/3100 Propane
  • Engine: 212cc OHV 4-Stroke
  • Starting system: Recoil
  • Fuel type: Gasoline/propane
  • Fuel tank: 3.6 gallons
  • Run time: up to 10 hrs at 1/2 load – gasoline; up to 12 hrs at 1/2 load – propane
  • Outlets: 4x Duplex 120V 20A (5-20R),1x 120V 30A (TT-30R), 1x 12V 8A receptacle
  • Noise level: 69 dBa
  • Dimensions: 24.5 x 17 x 16.5 in
  • Weight: 90 lbs.

Very similar in style and performance to the classic Sportsman GEN4000, the Sportsman GEN4000DFC has the unique advantage of being a dual fuel generator, meaning you can use either gasoline or propane to power it up. This gives you the freedom of being able to use whichever fuel you prefer, depending on your budget and the situation. This is a nice bonus, and many users appreciate the option to choose between fuel sources as they please.

The Sportsman GEN4000DFC can offer up to 4,000 watts of power and comes with a vast range of different outlets, including four 120V outlets, a 120V RV outlet for motorhomes, and a 12V DC outlet for charging up battery powered devices. It can run for 10 hours straight with the 3.6 gallon tank filled up with gasoline or even longer with propane, and it comes with a 1 year limited warranty. The warranty isn’t the longest out there, which is a minor disappointment with this model, but if you’re buying a Sportsman generator, you’ll usually have to cope with such a short warranty as this tends to be industry standard.

Users have been relatively impressed with the Sportsman GEN4000DFC overall, with many saying it offers just the right level of performance and functionality they need. It’s good for campers, in particular, and the dual fuel functionality and option to store up propane at home makes it a good option as an emergency backup power supply too.

  • Relatively quiet compared to other models
  • Dual fuel model offers flexibility of propane and gasoline
  • Strong power output
  • Plenty of output connections to suit all devices
  • Quite a short warranty

Sportsman GEN4000LPBest Propane Generator

It’s one of the most reliable and durable generators out there, and it even comes with some unique bonus features to provide additional safety, security, and convenience to the end user, including an auto fuel shut off safety valve and an automatic low oil shut down too.

With a strong 7 HP 4-Stroke OHV engine under the hood, this generator can offer up to 4,000 watts of power and is purely powered by propane. This will be a disadvantage in the eyes of some users, as propane is traditionally more expensive and a bit less accessible than gasoline. However, propane has a longer shelf life and is a lot easier to store in large quantities, so it’s perfect for many people and situations, like campers and RV owners.

The Sportsman GEN4000LP has a maximum runtime of 10 hours on a 1/2 load. It comes complete with a fuel hose and regulator and offers two 120V AC outlets and a 12V DC outlet for charging up batteries and battery powered devices.

A lot of people call this the best Sportsman generator for off-gridding.

The only real flaw for this model is that it’s so huge and heavy, so it’s a difficult one to move around from place to place. Fortunately, the manufacturer equipped it with wheels to make transportation a little easier.

  • Immensely powerful
  • Lots of different outlets to choose from
  • Very versatile generator
  • Huge fuel capacity
  • Easy electric starting system

It’s well equipped to handle almost any situation, working flawlessly as a backup generator and even being strong enough for work situations too.

The 7HP OHV 4-Stroke engine in the Sportsman GEN4000DF-SS is a very reliable and effective piece of equipment, giving this generator the edge over many competing models, and another big advantage of the Sportsman GEN4000DF-SS is that it’s a dual fuel generator, able to run on both propane and gasoline. This gives you the freedom to decide how you want to power up the generator, able to stock propane at your home or simply load up on cheap and accessible gasoline when you need it.

With a noise level of 69 dBa, the Sportsman GEN4000DF-SS is actually one of the quieter entries on our list. It’s still relatively noisy compared to some super silent generators out there, but it’s not too bad in this department and users have been impressed with how little noise it makes. At 91 lbs, it’s also a good compromise between power and practicality, and it comes with a reasonable selection of power outlets too.

This highly affordable Sportsman generator may not be able to boast of the same high power output and peak watts as some of the others, topping out at just 2,000 watts and featuring a fairly low powered 94cc OHV 4-Stroke engine, but it’s a reliable performer, powered by highly affordable and easily obtainable gasoline and fitted with a 1.2 gallon fuel tank.

Buying Guide

Now that we’ve looked at some of the best Sportsman generators on the market, it’s time to take a closer look at the various features and factors you need to consider when buying one of these models. It’s never wise to simply go out and buy the best rated generator or first generator you find without considering your own needs, what you’re going to be using the generator for, etc. This buying guide will give you all the details on choosing a Sportsman generator.

Features to consider while choosing a Sportsman generator

7 Best Sportsman Generators - Your Powerful OptionThere are many different features to think about when choosing a Sportsman generator, and it’s vital to consider each one of these features and think about how important they are to you. Some people, for instance, will care greatly about the overall fuel tank capacity and runtime of their generator, needing constant energy for an extended period of time, while others will place greater emphasis on the overall power output of the generator. Read on to learn more.


In simple terms, Sportsman generators can be divided into two main types: conventional and inverter. Conventional generators, like the Sportsman GEN2000, are the more traditional option of the two. They make use of an energy source like diesel or gasoline to power a motor, which in turn generates electricity. Inverter generators, like the Sportsman GEN2200DFI, are quite recent and effectively generate AC power just like a traditional generator but then convert it to DC and then back to AC, essentially resulting in the elimination of power fluctuations. This means they’re generally more flexible as you can adjust the speeds. They’re also quieter and more eco-friendly too, but conventional generators tend to offer way higher outputs and better value overall.

Power output

The power output of a generator effectively tells us how much power it is able to generate. Bigger isn’t always better here, however, as not everyone will need gigantic amounts of energy. If you don’t have a high demand for energy, you can get by with a smaller and more affordable option, like the Sportsman GEN2000, but if you need lots of power, for example for a work site or as an emergency backup generator in case of a natural disaster, you may want to choose one with a high power rating like the Sportsman GEN7500DF, which is also considered to be one of the best 7,500-Watt generators.

Fuel type

7 Best Sportsman Generators - Your Powerful OptionIn general, when it comes to Sportsman generators, the two main fuel types you’ll have to consider are gasoline and propane. Gasoline, used in the Sportsman GEN4000, has the advantage of being super affordable and easy to obtain, so it’ll save you the most money in the long run and is highly convenient too. Propane, meanwhile, as seen in the Sportsman GEN4000LP, has the advantages of having a longer shelf life than gasoline and is easier to store in big quantities. And if you have already decided that propane fuel option is the most suitable for you, then it is advisable to make a full survey of the best propane generator models before buying one of them.


The engine of your generator is what helps to generate power. It’s an integral component of the machine and there are a lot of different engines out there. Some are stronger, faster, more efficient, and more durable than others. In general, Sportsman generators all feature high quality engines, but the more expensive and advanced models will typically have better overall engines.

Fuel tank capacity and runtime

A key feature for many people is the overall fuel tank capacity and runtime of their Sportsman generator. Some people only need a generator for short, quick bursts of power in certain situations, like on camping trips, but if you’re going to be relying on the generator for an extended period of time, it makes sense to invest in a model with a long running time, like the Sportsman GEN4000DF-SS.


The outlets of your Sportsman generator allow you to actually connect the generator to various devices in order to power them up. The more outlets you have, the more options you’ll have in regard to the devices you can use with the generator, so if you want to have a flexible model that can work with lots of different things at once, it’s a good idea to choose a generator with many different outputs, like the Sportsman GEN7500DF.

Noise level

7 Best Sportsman Generators - Your Powerful OptionGenerators can’t exactly be described as silent. They make noise when they operate, but some are much quieter than others. If you don’t want to be disturbed while running your generator, choose one with a low noise level, like the Sportsman GEN2200DFI.

Dimensions and weight

If you’re planning to carry the generator around, transporting it from place to place and using it in different situations and environments, opting for a relatively compact and lightweight generator, like the Sportsman GEN2000, is the best option. If you don’t plan on moving the generator much, you can choose a heavier model with no worries.


The last thing you want with your Sportsman generator is for it to fail, but faults and technical issues can occur, so it’s always reassuring to have a good warranty protecting your purchase. If you’re worried about any issues in the future, be sure to select a Sportsman generator with the longest possible warranty.

Extra features

Some Sportsman generators can come with little extra features that make them easier to use or move around. The GEN7500DF, for example, is quite a heavy and high powered model, so it has wheels to allow you to roll it around, while the relatively lightweight GEN2200DFI comes with a handle to make it simpler to carry from place to place.


Yes, it is possible to connect a generator to a breaker box, but you’ll need to either seek professional help with this or ensure that you do your research and know exactly what you’re doing before you make any attempt to wire up the system. Before connecting a generator to a breaker box, you’ll need an approved transfer switch. It’s also wise to get the whole set-up checked over by a professional to ensure it meets safety standards, rather than running the risk of harming yourself or anyone else involved in the wiring.

Absolutely. Sportsman generators have been used for camping and personal use for years, but they’ve also been trusted at many worksites around the nation. Naturally, in order to supply a work site with sufficient power, workers will need to choose the better and stronger models of Sportsman generators, like the Sportsman GEN4000 and Sportsman GEN4000DFC, and it’s important to measure the needs and demands of your work before selecting a generator in order to find a model that can satisfy those needs adequately, rather than investing in an insufficient power source.

Yes, Sportsman generators are parallel compatible, provided you make use of the official Sportsman parallel cable kits, which are sold separately to the generators and work to increase wattage by combining the power and output of two generators. By doubling the power, you’ll have access to much greater energy output overall, so this is a good option for work sites or situations where large amounts of power are needed.

Our Verdict

Overall, our top rated Sportsman generator is the Sportsman GEN4000. Offering great runtime, plenty of power, and all the outlet options you need in a comprehensive and fairly priced package, this is the perfect portable generator for almost any situation.

The next best Sportsman generator is the Sportsman GEN4000DFC, and this was our best dual fuel generator too. The dual fuel facet of this model gives the user plenty of versatility in terms of how they use it, and the GEN4000DFC is able to offer solid performance and strong power output every time.

Our third favorite Sportsman generator is the Sportsman GEN4000LP. With its propane only design, durable build, and unique safety features, all combined with a powerful engine and impressive runtime, this is the ideal all-rounder for your portable generator needs.
