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 sure of their ability to power their fridges, cooking tools, heating and lighting equipment during power failures
  • Camping and tailgating hobbyists looking for a portable power source
  • Professionals who want to be able to deliver results, even during a power failure

The following sections will present you in detail its power characteristics, the different outlets it offers, its overall portability, the extra features it benefits from, and any relevant emission compliance details.

Power & Run Time

The Predator 8750 in use

The Predator 8750

The Predator 8750's engine, 420 cc (12 hp) OHV 4-stroke, fueled by gasoline, can deliver 120/240V. It provides a running wattage of 7000W and reaches a peak wattage of 8750W.

With a noise rating of 75 dBA (just slightly more noisy than a vacuum cleaner), the inverter generator features a simple traditional pull-start mechanism, but also a convenient and easy-to-use electric starter (battery included).

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

As the 8750 produces a clean sine wave, with a <3% Total Harmonic Disruption (THD), sensitive electronics may be plugged in the AC outlets safely.

Outlets

The control panel features the upcoming 5 AC outlets:

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

Furthermore, it has 3 DC outlets: there's two 5V USB ports (USB-A) with which charging of electronics like mobile phones and tablets is made convenient 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 generator is designed for ideal use outdoors and in rough environments.

Even though this device may be technically portable (as in movable), manipulation and transportation without special equipment can be a challenge, as it weighs 151 pounds. Nevertheless, it can still be moved quite conveniently with the help of its set of wheels (⌀10") and its folding handle, once it is placed on the ground.

Features

Panel of the Predator 8750

The 8750's control panel

The 8750's control center features a convenient meter showing you voltage, frequency and lifetime hours to aid you with the monitoring of 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.

Thanks to a built-in fuel gauge, the inverter generator allows you to quickly, conveniently and easily check the gas level at a glance.

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.

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. It’s a welcomed additional security feature, but don’t forget to always take your generator outside (opens in a new tab).

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. It can therefore be sold and purchased in all 50 states, including California.

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

Product Video

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. If you are concerned by weight, one of the champions in the above-mentioned power range is the Sportsman GEN85KIDF, with a dry weight of just 133 pounds.
  • The inverter generator can be considered average in its noise for its power category, as it is rated at 75 dBA. If you’d prefer a less noisy device, one of the most quiet devices, which share the same power range with this one, is the Powerhorse 7500i, whose lowest noise levels reach just 55 dBA.
  • Given that the 8750 reaches an autonomy of up to 15 hours with a full tank and at 25% load, it is placed within the average autonomy range of similarly powerful generators. Furthermore, considering the run times, one of the generators which have a roughly same power output, with the highest autonomy, is the Powerhorse 7500i, as it provides up to 16 hours.
  • Run times are important, yet thanks to their dependence on the fuel capacity, they should be judged along with the fuel consumption of the device. This inverter generator can be considered as fuel efficient, due to its low estimated fuel consumption of only 0.39 GPH (gallon per hour) at 25% load, within the aforementioned wattage range. If you are concerned with gasoline efficiency, having a fuel consumption of just 0.35 GPH, the Energizer eZV8000 is a device you should look out for.

Price comparison

As you can see from this interactive chart, when compared to other 6500-7500W 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.

    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)

    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
