Sportsman Generator Reviews

Sportsman has some of the most affordable generators in the market today. Not to take them lightly, most of these generators compete favorably with other pricier brands in performance and usability. A quick search in online reviews reveals some incredible ratings and positive feedback from current users too.

For this Sportsman generator review, we aim to give you a closer look at everything about these generators, including their common pros and cons.

In our analysis of this brand’s catalog, we also came across a couple of the best Sportsman generators worth considering today.

Distinguishing Features of Sportsman Generators

  • Power output range– Buffalo Sportsman generators range from 1000w to 10,000w.
  • Single, dual-fuel, and tri-fuel variants– some of these generators give you the option to run them on dual fuel (gasoline and propane) or tri-fuel (gasoline, propane, and natural gas).
  • 4-stroke OHV engine– all Sportsman generators are fitted with a 4-stroke OHV engine, which is considerably more reliable than 2-stroke engines.
  • Electric start– a few of these generators have a built-in electric start for hassle-free startups. However, we noted that some of them don’t ship with the battery in the package.
  • Automatic low-oil and low-oil shutdowns– all Sportsman generators will shut down automatically if you fail to add fuel or oil timely, preventing engine damage.


Sportsman generators are among the cheapest in the market today at almost any power category. The average cost for a Sportsman generator is around $590. At this price range, you’re looking at generators in the 5000-6000w range. At about $1450, you’ll find generators with around 10,000 peak watts and extended runtimes.

The lowest price for a Sportsman generator is about $150. This category has the least potent generators ideal for powering low-power appliances and devices and a couple of lights.

Are Sportsman generators good?

Sportsman generators are good, but not perfect. These generators have a lot to go for, especially if you’re looking for the most affordable generators. But there are a few things that you want to keep in mind as we will explain in this Sportsman generators review. Let’s start with the positives.

Overall, we appreciate that these generators use 4-stroke OHV engines despite their low price range. Portable generators with OHV engines have the upper hand in fuel efficiency, high power output, and reduced fuel and oil combustion.

Moreover, we like that these engines come in all types from single-fuel to dual and triple-fuel varieties. Most of these generators have above-average runtimes, too. This is an incredible thing to know when buying a budget generator. Importantly, these engines are fitted with automatic low-oil and low-fuel shutdown features, which boost the durability of the generator by preventing damage.

The fact that Sportsman generators are EPA-approved also shows that there’s a good amount of thoughtfulness in their design and construction.

Switching gear to the downsides, most Sportsman generators are notably louder than their slightly pricier competitors. If you plan to use the generator regularly, you’ll need to lower the noise output for your neighbors’ sake. If you need a quiet generator, then check our article about the best quietest generators currently on the market.

Secondly, we’re disappointed that Sportsman generators come with a warranty period of 3 months to 1 year. This is significantly shorter than the 2-3 years that most generator brands offer.

Lastly, beware that Buffalo Corp. keeps the cost of these generators down by not including the wheel kit, foldable handles, and battery (where applicable). You may need to purchase these separately.
