Description

Powered by a reliable Predator gas engine, this generator is ideal for emergencies, job site use, recreation, household, lawn and garden, heating and cooling.

Zoom on the Predator 8750

In summary, the Predator 8750 is a portable generator especially useful for:

  • Food van owners who know that just a short power outage could lose them hundreds of dollars
  • Homeowners in need of an emergency backup power for their essentials
  • Professionals who want to be able to deliver results, even during a power failure
  • RV travellers looking for even more independence

In the sections ahead, the power characteristics, availability of various outlets, the portability, and any additional features of the device shall be discussed, including its emission compliance information.

Power & Run Time

The Predator 8750 is powered by a 420 cc (13 hp) OHV 4-stroke engine. It delivers 120/240V, runs on gasoline and offers a running wattage of 7000W as well as a peak wattage of 8750W.

The generator features a simple traditional pull-start mechanism and also a convenient and easy-to-use electric starter (battery not included). It is rated for a noise of 76 dBA (less noisy than a shower).

With a fuel capacity of 6.6 gallons, the 8750 may run for around 12 hours at 50% load with a full tank (fuel consumption around 0.55 GPH).

Outlets

The control panel provides the upcoming 6 AC outlets:

Two Duplexes 120V 20A (5-20R) GFCI
120V 30A (L5-30R) receptacle
120/240V 30A (L14-30R) receptacle

In addition, it provides 1 DC outlet: there's a 12V 8A (cigarette lighter style) receptacle with which charging your batteries is made easy.

This Predator generator features an L5-30R receptacle, enabling an easy RV connection via an L5-30P to TT-30R adaptor. However, it is still not quite RV ready. Besides, as it features a twist-lock L14-30R receptacle, the 8750 is transfer switch ready: in case of a power outage, you will be easily able to connect it to a breaker box and power your household.

Portability

The design of the Predator 8750 is a typical, open frame, with the dimensions of L26.9 x W22 x H22.8 in, offering support and stability and enabling the possibility of raising it above ground level. The device has been designed for tough environments and demanding outdoor use.

Since the generator weighs 183 lbs, it will be incredibly difficult to manually lift it and transport it, even though it is technically considered to 'be portable' (in the sense that it is movable). Thus, you may also want to consider purchasing a wheel kit for this generator, similar to this one (opens in a new tab).

Features

Panel of the Predator 8750

The 8750's control panel

A light indicator allows you to instantly see if its oil levels are insufficient.

The fuel level of the generator can be determined quickly, easily, and conveniently with the help of its built-in fuel gauge.

From a security point of view, the generator is equipped with an automatic low oil shut-off and an overload protection (circuit breaker), giving you a peace of mind during use.

Regarding its accessories, besides the aforementioned features, the Predator 8750's box includes the typical documentation and an owner's manual (opens in a new tab), letting you start it right off the bat.

Emissions

The Predator 8750 is EPA-approved and CARB-compliant. Thus, selling and purchasing this generator is allowed in each of the 50 states, including California.

Moreover, it features a spark arrestor and therefore, can be used in forested areas.

Product Videos

The Predator 8750 versus other generators

The following charts are provided to give you an idea of how some of the key specs of the Predator 8750 compare to generators of similar power (between 6500 and 7500 W).

  • At a weight of 183 pounds, the Predator 8750 places in the expected weight range of the generators in the 6500-7500 rated wattage range. If weight is your top priority, one of the champions in this power category is the Sportsman GEN85KIDF, weighing just 133 pounds.
  • Among the generators of a comparable running wattage, this generator with a lowest noise of 76 dBA can be judged as noisy. If noise emissions are important to you, one of the least noisy generators of this power range is the Powerhorse 7500i with only 55 dBA.
  • Since the 8750 boasts with a run time of around 12 hours at 50% load, it can be safely judged as a device of a higher run time than most generators of a comparable output. If concerned with autonomy, one of the products of a comparable power output, which offers the highest run time, is the Generac XC6500E, boasting with around 14 hours.
  • The run time is important, but also hugely depends on the capacity of the fuel tank and doesn't mean much if we don't talk about fuel consumption as well. At an estimated fuel consumption of 0.55 GPH (gallon per hour) at 50% load, this generator is a rather fuel efficient one within its wattage category. If you wish to acquire one of the most gasoline efficient products of this power range, the Lifan ESI 7000iER-EFI, with a fuel consumption of 0.38 GPH could be in your good books.

Here's a list of the most popular specific comparisons:

    I’m thoroughly impressed with this machine, I’ve bought 2 of them and they both continue to work without issue. As long as the maintenance is kept up, this generator should last many years. On another note, thanks for using my videos on this very thorough breakdown, I’m glad my content has been helpful to others mostly after this rough winter storm we had in TX. My dad ran his whole house on the Predator for 60+ hours during this power outage.

    + PROS:
    • Very powerful, fuel-efficient, manageable weight, metal gas tank, long runtime, and sturdy construction.
    - CONS:
    • No remote (I'm about to fix that, video coming soon)

    Power has been out for 3 days because of ice storm. And its been running none stop as along as can keep gas in it. Of course I can only use 5 gals at a time because that’s the size of the can. I get 8-10 hours running forsure..I like it a lot and its worth it. Just make sure you start it once a year if you use it or not..

    + PROS:
    • Starts great. As long as you start it once a year.
    • Great on fuel.
    • It runs the whole house.
    - CONS:
    • It is a bit loud.
    • It hold 5 gals for sure.
    • Can use some bigger wheels.

    We use the predator 7000/8750 generator as an emergency whole house generator. It’s wired through a transfer switch and easily powers our country home – including electric water heater, furnace, well pump, and lights… we live the same on the grid as we do on this generator.

    We’ve run this generator continuously for the past 3 weeks due to wind and snow storms. I have it directly plumbed to a 55 gallon drum of fuel and it just does it’s thing. Couldn’t be happier. Will definitely need an oil change when the power is restored…

    + PROS:
    • Long run time
    • Runs the entire house (washer, gas dryer, furnace, electric hot water tank, well pump, lights, coffee maker, microwave... just need to watch how much you turn on at once)
    • 230v / 30A power - easy to connect to electric panel / transfer switch
    • Reliable
    • Easy to use & maintain
    - CONS:
    • Noisy

    I have owned this generator for well over a year now and was finally able to put it to the test last night. It started right away even after sitting outside under a cover for a year. I use sta-bil in the gas so I’m sure that helped. I was running 2 full size refrigerators, a 24,000 btu air conditioner, an old school plasma TV and cable box plus sound amplifier and miscellaneous light fixtures that were all converted to LED bulbs. This unit did great! I was without power last night in California during a record heat wave. It ran for about 6 hours before the power came back on. It is a little on the noisy side but it worked flawlessly and I’m totally satisfied. I gave a slightly less score for performance because of the noise.

    + PROS:
    • Electric start rocks! Very easy unit to start even with pull cord.
    - CONS:
    • It is a little bit noisy. Good thing my neighbors constantly have big noisy parties till 3 in the morning so I don't mind bothering them once in a blue moon during an outage; -)

    This unit is a great deal for the price. I have used it to power my entire house at with zero issues. It starts very easy and has plenty of power. The wheel kit is a must, as this weighs a lot and is almost impossible to move by yourself without the wheels. All in all its a very good unit at such a low cost. I have 8 hours total runtime at this point within the last 3 months. Manual is written nicely for a unit of lower price.

    + PROS:
    • Starts very easy
    • Includes 240V connection for whole house application
    • Easy to fill with gas
    • Power Output for Price
    - CONS:
    • Weight
    • Wheel Kit not included
    • Noise
