  • RV travellers who wish to upgrade their experience to another level

In the following paragraphs, we shall explore the power characteristics, available outlets, portability, and any additional features of the device, along with its emission compliance information.

Power & Run Time

The Sportsman GEN85KIDF in use

The Sportsman GEN85KIDF

Thanks to its dual-fuel technology, the Sportsman GEN85KIDF delivers 120/240V and offers power and versatility. When gasoline-powered, it benefits from a running wattage of 7,000W and a peak wattage of 8,750W. When propane-powered, it has 6,300 rated watts and 7,900 peak watts.

The inverter generator is rated for a noise of 70 dBA (just as noisy as a shower). Its starting mechanisms include a conventional pull-start mechanism and a convenient and easy-to-use electric starter (battery not included).

The GEN85KIDF, with a fuel capacity of 7 gallons, reaches a run time of around 10 hours at 50% load utilizing gasoline (fuel consumption around 0.7 GPH). Alternatively, it can reach a run time of around 6 hours (on a 20 lbs tank - propane consumption around 0.78 GPH) with propane.


The control panel features the following 5 AC outlets:

Two Duplexes 120V 20A (5-20R) GFCI
120/240V 50A (14-50R) receptacle

In addition, it provides 2 DC outlets: there's a 12V 8A receptacle with which charging your batteries is made easy and a 5V USB port allowing you to conveniently charge electronics such as mobile phones and tablets.

If you own an RV with a 50-amp service, you can consider this Sportsman unit as RV-ready, as it features a 14-50R outlet.


The Sportsman GEN85KIDF has the following dimensions: L29.5 x W23.5 x H24 in. In combination with its conventional, open frame design, they provide support and allow the generator to be raised above ground level. The design is ideal for rough environments and demanding outdoor use.

As the generator's weight is 133 pounds, manually moving it or transporting it may be challenging, despite the fact that it is technically considered 'portable' (movable).


Panel of the Sportsman GEN85KIDF

The GEN85KIDF's control panel

Several light indicators serve to show you when the oil level is too low, the generator is overloaded and the generator is ready.

As for its security measures, the device features an automatic low oil shut-off and an overload protection (circuit breaker), letting you use it with a peace of mind.

With the basic documentation and an owner's manual (opens in a new tab), letting you start the generator quickly, the Sportsman GEN85KIDF also comes with several accessories, including: propane hose, battery charging cables and tool kit.


The Sportsman GEN85KIDF is EPA approved, but NOT CARB-compliant. Thus, it cannot be purchased or sold in California.

However, it features a spark arrestor and thus, may be used in forested areas.

Product Video

The Sportsman GEN85KIDF versus other generators

The following charts are provided to give you an idea of how some of the key specs of the Sportsman GEN85KIDF compare to dual fuel generators of similar power (between 6500 and 7500 W).

  • In terms of its dry weight, the Sportsman GEN85KIDF stands at only 133 lbs, meaning that is one of the lightest dual fuel devices of the 6500-7500 rated wattage category
  • This inverter generator has a somewhat average expected noise for its type and power range, rated at 70 dBA. If you are concerned with noise, check out the Champion 201175, which is one of the least noisy generators in its power range, with a noise rating of just 61 dBA.
  • Given that the GEN85KIDF reaches an autonomy of around 10 hours with a full tank and at 50% load, it is placed within the average autonomy range of similarly powerful dual fuel generators. If you consider autonomy on a single full tank as one of the deciding factors, one of the generators in the same power range that offers the highest run time is the Firman H07552, with around 12 hours.
  • While the run time is an important parameter, it is dependent on the fuel tank's capacity and thus, doesn't say much on its own unless we consider fuel consumption as well. This inverter generator is not fuel efficient compared to devices of similar output: its estimated fuel consumption stands at 0.7 GPH at a 50% load. If fuel consumption is your top priority, we suggest to check out the DuroMax XP7500DX, which has a fuel consumption of only 0.53 GPH and thus, is one of the most efficient devices in our database.

Price comparison

As you can see from these interactive charts, when compared to other 6500-7500W inverter generators, the Sportsman GEN85KIDF is on the average side of the price range.

Therefore, this generator nicely fits in the expected budget for this kind of product.

The bottom line

  • In the expected price range
  • Dual Fuel
  • Several accessories included
  • GFCI Outlets
  • Electric start
  • Lightweight for its kind (133 lbs)
  • Acceptable noise (70 dBA)
  • Decent run time

    Very Dissapointed October 18, 2023 at 8:57 pm

    I ordered one from Home Depot. HD shipped very fast. Did not start, called Sportsman, no apology that their top of the line generator did not run out of the box, told them no spark, they said they’d mail me a new coil and spark plug that I could install myself. Two weeks later I get the parts added them, and while adding noticed critical parts missing. Unfortunately the generator was missing parts, governor arm, governor spring and governor linkage, and who knows what else. Sportsmans needs better QC than adding a sticker saying it passed QC. How about actually checking if it’s completely assembled. I returned it to HD, no complaints with HD, but I will be looking for a different brand than Sportsman. I highly doubt I’d ever buy one of their products when that’s how they box up and deliver their top of the line most expensive generator. Unlike other user who went the trouble of getting and returning the generator 3 times before getting a working one, I will not waste any more of my time or money like that or with Sportsman.

    + PROS:
    • A great way to use a mechanic's tool set. Great for people what want one that doesn't run and will require lots of work.
    - CONS:
    • No Quality control, missing parts. No Quality Control!

  2. 4.15

    I’ve been using the Buffalo Sportsman 8750 for a few weeks now and I am very pleased with its performance. Many of the complaints I’ve read centered around the frame. I will concede that the frame is a flimsy piece of junk so I must have been lucky in that my unit’s frame came straight and true. With that in mind, plus the absence of any wheel kit, I decided to mount it onto a large 4-wheel furniture dolly with 4″ wheels so moving it around is a snap. The dolly also gives a certain degree of added rigidity so the chances of tweaking the flimsy frame have been greatly minimized.

    I only use it at my deer camp cabin. I call it a deer camp but it’s really a small “getaway” office where I can go and work undisturbed and then go shoot hogs in the evening. I built a small cabin and I installed a breaker box with several circuits. Inside my cabin I have:
    • A 220v, 12k-btu window AC (a Texas necessity)
    • A dehumidifier
    • A small fridge
    • A coffee pot
    • A bunch of lights
    • An electric cook top stove
    • Computer with multiple monitors
    • Countless phone chargers.
    • My wife’s quilting equipment, which is basically a computer controlled precision sewing machine.
    • Plus any number of power tools I need to use, a 4’ shop fan and tool battery chargers.

    I mention everything, especially the computer gear, because other generators have given me issues. This Sportsman 8750 gives a steady Hz and voltage with a pure sine wave of power. Having that “grid like” steady power stream really makes a huge difference in the performance of computer gear. Even my UPS is happy. The LED lights would flicker annoyingly whenever the AC or even when the coffee pot kicked on. That is all gone.

    I get much better fuel economy than what the Buffalo Company have published. With all my gear running, I’m using close to 9 gallons of gas per 24 hours. The large Generac that this unit replaced was not near that efficient. When the temperature cools in the fall (AC not needed as much) I fully expect that number to go down to 8 or even 7 gallons/24 hrs.

    When I get to the cabin, the generator gets started, and 3-5 days later when I leave, it gets turned off. For the days that I’m there, it’s on 24/7 and never has a hiccup. When we pack up to leave, it gets turned off, I change the oil and then head home.

    It is hard to start when cold and I believe that is because the ignition system relies on voltage from a spinning stator. It takes a few brisk pulls to build the voltage up in the capacitor. Is that a deal breaker? Not really for me. It is certainly a design flaw and for what they are charging, should have been accounted for. It does have an electric start but is not shipped with a battery. I don’t yet have the cables built up to use the electric starter but I’m hoping using a battery makes cold starting easier. As it is now, it’s 4 or 5 brisk pulls and then it’s like it’s been kicked out of a nap. “Oh, were you talking to me? Did you need something?” Again, once running, no issues at all.

    I haven’t used it with propane. Since I’m out in the boonies, I would have to build up a stock of propane tanks and at $25 a pop, I’ll wait a bit on that one. Plus, from what I’ve read, it would cost more to operate. For now, I just show up with 6 gas cans in the back of the truck and that will last me 4 days of 24/7 operation.

    Other things I like is that it runs a lot cooler than the Generac I was running before. I have it in a sound dampening box and removing the heat was a big deal with the Generac. With this Sportsman 8750, I have found that I need much less forced air running through the box to keep it cool. Less air means fewer fans pulling less amperage. The result is much better better fuel economy.

    I wouldn’t use the adjective “quiet” to describe it but it puts out quite a few less dBspl than the Generac XG8000e that I replaced. Even when running full tilt, the sound output is noticeably less. Certainly not quiet like a $6000 Honda, but much less noise than any other 8K generator.

    Overall, I wouldn’t want to spend what Lowe’s and Home Depot are charging so if this model fits your needs, look for a deal somewhere. Put a critical eye on the frame to make sure everything is lined up, and if it looks good, you won’t be disappointed. Plan on mounting it on something with wheels and budget for a small lawnmower battery and a set of EC5 leads.

    That’s all I got.

    + PROS:
    • Pure sine wave power.
    • Good fuel economy.
    • Runs cool.
    • Dual fuel capable.
    - CONS:
    • Harder to start than it has to be.
    • The frame is a piece of junk
    • No wheel kit available
    • Retail price is a joke.

  3. 1.25

    Bought this from Amazon for $1200 as it was the only 7KW (240V 50A) Inverter I could find that would run on propane. It arrived in a beat up cardboard box that superficially looked ok. Only after unboxing did I discover that the frame/engine carriers were badly bent. So badly bent (1″) that the metal touched the ground, not the rubber feet, and it kind of rocked back and forth on the high point. Otherwise I might not have noticed being in the middle under the whole thing.

    I thought someone must have dropped it off a fork lift or thrown it out the back of a truck.

    So… yay for Amazon, they promptly sent an identical replacement. Literally, identical as it arrived 4 days later again with a similarly bent frame. although this time not quite as bad (1/2″) and the rubber feet actually kept the unit off the ground.

    The second time I paid more attention to how it was boxed and it’s clear to me two things:
    #1 Buffalo/Sportsman puts a little styrofoam block under the engine that is intended to support it during shipping, this is grossly insufficient packaging.
    #2 the frame itself is just too weak to properly support the engine regardless of the styrofoam block. The motor carrier ought to be made out much thicker/stronger U channels that would NEVER bend.

    It’s a shame as it’s a unique beast and spec wise exactly what I wanted. Hoping Champion makes a similar model. Currently their dual fuel inverters top out at around 4KW.

    Two other notes if you still are considering buying this.
    #1 I found this impossible to pull start. That could be because I’m starting it on propane and at 6000′ elevation. However, that also make it all the more annoying that they don’t include a built in starter battery. Further hooking a battery up requires a fairly unusual EC5 connector. I bought a car jump start battery from Costco that had the same style connector. That worked, but it was still hard to start, 4-5 tries, but that all was after 50+ tries pulling the cord. Keep in mind it won’t re-charge the battery either so you have to have another way to charge it unlike a built in battery.

    #2 It’s much louder than my 2KW Champion Inverter (obviously), but it’s not horrible either. I would call it “average”.

    + PROS:
    • Unique in being a 7/8KW Duel Fuel Inverter Generator
    - CONS:
    • Cheap frame bent in shipping. Cheap packaging didn't keep that from happening. Contacting Buffalo Tools was told "Not our problem contact Amazon".
