Description

Zoom on the Predator 8750

In a nutshell, the Predator 8750 is a powerful portable inverter generator mostly geared towards:

  • Food truck owners who do not wish to see their business interrupted under any circumstances
  • Homeowners who want to be able to use the most necessary devices in their household, even during a blackout
  • Camping and tailgating hobbyists looking for a portable power source
  • Professionals who want to be able to deliver results, even during a power failure

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 in use

The Predator 8750

The Predator 8750 is powered by a 420 cc (12 hp) OHV 4-stroke engine. It delivers 120/240V, runs on gasoline and offers a running wattage of 7,000W as well as a peak wattage of 8,750W.

The inverter generator features a simple traditional pull-start mechanism and also a convenient and easy-to-use electric starter (battery included). It is rated for a noise of 75 dBA (just slightly more noisy than a vacuum cleaner).

The 8750 can operate for up to 15 hours with a full tank (fuel consumption around 0.39 GPH), due to its fuel capacity of 5.9 gallons.

Delicate electronics can be plugged in an AC outlets safely, as the 8750 generates a clean sine wave, reaching a <3% Total Harmonic Distortion (THD).

Outlets

The control panel includes the following 5 AC outlets:

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

It also sports 3 DC outlets: there's two 5V USB ports (USB-A) allowing you to conveniently charge electronics such as mobile phones and tablets and a 12V 10A receptacle with which charging your batteries is made easy.

Because the 8750 is equipped with a twist-lock L14-30R receptacle, it is transfer switch ready: it can power your home during a power outage, as it can be easily connected to your breaker box to power your household.

Portability

The conventional, open frame design of the Predator 8750 offers stability and allows the generator to be raised above ground level. The featured design is ideal for the outdoors and all tough environments.

While the generator is considered to be technically 'portable' (in the sense that you can move it), manually lifting and transporting it may be challenging, due to its high weight of 151 lbs. Still, once it is on the ground, its set of wheels (⌀10") and its folding handle can easily solve the issue of low mobility and allow for easy relocation of the device.

Features

Panel of the Predator 8750

The 8750's control panel

The 8750 and its control panel include a convenient meter, which displays voltage, frequency and lifetime hours. This feature comes handy when monitoring its status and activity.

In addition to this info, some light indicators allow you to instantly see if the generator is ready, the generator is on overload and its oil levels are insufficient.

A built-in fuel gauge allows for a quick, easy and convenient check of the fuel level of the inverter generator.

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

The unit also benefits from the Predator's CO SECURE™ carbon monoxide detection. This system monitors the accumulation of CO gas while the generator is running and will shut off the engine if the levels become dangerously high.

Along the basic documentation and an owner's manual (opens in a new tab), useful for starting the generator right away, the Predator 8750's package also includes these accessories: battery charging cables, tool kit and funnel.

Emissions

The Predator 8750 is EPA-approved and CARB-compliant. Therefore, its sale and purchase are permitted in all of the 50 states, including California.

Moreover, it features a spark arrestor, which makes it suitable for use in forested areas.

The unit also meets the ANSI/PGMA G300-2018 safety and performance requirements.

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).

  • As for its weight, the Predator 8750 weighs only 151 pounds, making it one of the lighter generators in the 6500-7500 rated wattage category. Regarding dry weight, one of the champions in the same power range is the Sportsman GEN85KIDF, with a dry weight of only 133 lbs.
  • If compared to generators capable of producing a similar running wattage, this inverter generator with a lowest emitted noise of 75 dBA can be considered somewhat 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.
  • As the 8750 offers up to 15 hours run time on a full tank at a 25% load, it falls within the average autonomy range among the generators of a similar power. Furthermore, considering the run times, one of the generators which have a roughly same power output, with the highest autonomy, is the DuroMax XP8500EH, as it provides up to 25 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. As this inverter generator uses an estimated 0.39 GPH (gallon per hour) at a 25% load, it finds itself in the average gasoline consumption range of similar products. If you wish to acquire one of the most gasoline efficient products of this power range, the DuroMax XP7500DX, with a fuel consumption of 0.29 GPH could be in your good books.
According to our stats, the following comparison is pretty popular: Predator 8750 vs Predator 9500.

Price comparison

As you can see from these interactive charts, when compared to other 6500-7500W inverter generators, the Predator 8750 is on the average side of the price range.

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

    Had the Predator 8750 now for 3 years. On day 4 of this power outtage and its still running strong. Keep the oil changed. Add fuel stabilizer if gas is going to set in it for awile, Start it regularly. I run mine about 1/2 hour every 2 months.

    + PROS:
    • 4 days in a row and still running strong!
    - CONS:
    • Noisy

    Bought this generator and only used it maybe 15 days. The generator has stopped putting out enough voltage. Harbor Freight is a HORRIBLE company to buy generators from. I am sitting here with this generator and HARBOR FREIGHT cannot tell you how to fix it. DO NOT BUY FROM HARBOR FREIGHT AND DO NOT BUY THIS GENERATOR .

    + PROS:
    • Nothing
    - CONS:
    • Horrible

    Need a schematic. Price point is excellent as all harbor freight tools are. BUT get what you pay for.mine will not start by Battery.

    + PROS:
    • Good price. Maybe if it will run.
    - CONS:
    • Almost impossible to fill oil. No schematic. Will not start on electric. No idea or part number for alligator clip cable with a angled plug. Have to search for spark plug again as NO SCHEMA TIC

    This is an inverter generator and for the price that is a big selling point, however I don’t understand why they recommend using a surge protector with it. I am using one, but don’t see why it is necessary for an inverter.

    + PROS:
    • BIG plus, this is an INVERTER generator.
    - CONS:
    • Quite noisy, but it is outside my house and acceptable. Manual is not very good and incomplete. Oil fill is slow and will overflow before it is completely full, so it must be filled slowly. Will NOT start if it isn’t full of oil. Esc must be off when starting, but can be turned on after it has started running (will slow engine slightly and reduce noise level). Manual doesn’t mention why there is a cord with alligator clips on one end and what looks like an AC plug on the other (looks really dangerous).

    Like anything if you take care of it,it will take care of you.Did a lot of research on generators the 8750 was a no brainer if you want to add natural gas,propane it can be done easily.Other predator older model 9000 is still going strong for 551 bucks try to beat that.

    + PROS:
    • Quieter than older model runs great
    - CONS:
    • Warranty HF should give at least a year warranty with the price of this unit

    Just bought one today. Had a problem with a bad vendor on the champion version 100520. Have a Honda eu2000 with 550 hours, zero problems, regular maintenance. Needed to power well pump, fridge,freezer, etc. Not for hvac or water heater. Started up great. Nice idle control, about as loud as a riding mower when running close to 7000 watts. Running a 30 amp transfer to main.

    + PROS:
    • Cost effective inverter.
    - CONS:
    • Can be a little loud.(It's not a Honda,lol)
