Our new, larger gas tank means you can enjoy run times up to 16 hours @ 50% load. (source: Harbor Freight)

Zoom on the Predator 4375

In a nutshell, the Predator 4375 is a compact portable generator mostly geared towards:

  • RV travellers wishing to enhance their freedom and nomad lifestyle
  • Amateur DIY lovers
  • Homeowners who want to be able to use the most necessary devices in their household, even during a blackout
  • 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 4375's engine, 212 cc (6.5 hp) OHV 4-stroke, fueled by gasoline, can deliver 120/240V. It provides a running wattage of 3500W and reaches a peak wattage of 4375W.

With a noise rating of 72 dBA (just slightly more noisy than a dishwasher), the generator features a conventional pull-start mechanism.

The fuel capacity of 4 gallons allows the 4375 to operate for around 16 hours at 50% load with a full tank (fuel consumption around 0.25 GPH).

Several examples of what the generator may allow you to power simultaneously are:Note: The examples above are based on a maximum load of 75% and estimated wattages. The devices also may not be able to start at the same time. For a more accurate estimation, use our wattage calculator.

Outlets

The control panel features the following 5 AC outlets:

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

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

Due to the featured twist-lock L14-30R receptacle, the 4375 is transfer switch ready: you may connect it to a breaker box to power your household during a power outage.

Portability

The dimensions of the Predator 4375, which are L23.3 x W18.7 x H19.3 in, and its typical, open frame design provides stability and enables the generator to be raised above ground level. The design is ideal for rough environments and demanding outdoor use.

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 103.5 lbs. Never less, thanks to a wheel kit (separate purchase) (a decent solution to its lack of maneuverability), the generator can be easily moved, once placed the ground.

The 4375's control panel

When its oil levels are insufficient, you will be informed by the featured light indicator.

The generator allows for a quick, easy and convenient assessment of its gas level, as it is equipped with a built-in fuel gauge.

From a security standpoint, the product offers an overload protection (circuit breaker) and an automatic low oil shut-off, allowing you to use it with a peace of mind.

Regarding its accessories, besides the aforementioned features, the Predator 4375's box includes the typical documentation and a user manual, letting you start it right off the bat.

Emissions

The Predator 4375 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 and thus, may be used in forested areas.

The Predator 4375 versus other generators

The following charts are provided to give you an idea of how some of the key specs of the Predator 4375 compare to generators of similar power (between 3000 and 4000 W).

  • As its weight is 103.5 pounds, the Predator 4375 falls in the expected weight range of the devices in the 3000-4000 rated wattage category. If weight is your top priority, one of the champions in this power category is the WEN GN400i, weighing just 66.1 pounds.
  • This generator, with its lowest possible noise rated at 72 dBA falls into the more noisy category, compared to other devise of a similar running wattage. If noise emissions are important to you, one of the least noisy generators of this power range is the Westinghouse iGen4500 with only 52 dBA.
  • Since the 4375 boasts with a run time of 16 hours at 50% load, it can be safely judged as a device of a higher run time than most generators of a comparable output.
  • 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 generator is one of the more fuel efficient models of the aforementioned output range, as its estimated fuel consumption reaches just 0.25 GPH (gallon per hour) at 50% load. If you are concerned with gasoline efficiency, having a fuel consumption of just 0.17 GPH, the Westinghouse iGen4200 is a device you should look out for.

The bottom line

STRENGTHS:
  • High run time
