Powered by a reliable Predator® gas engine, this generator is ideal for emergencies, job-sites, food trucks, and outdoor recreation. GFCI outlets, larger fuel tank, longer run time make this generator an unbeatable value. 4375 starting watts and 3500 running watts make this unit capable of powering several home essentials during an outage or providing power on the go. Our new, larger gas tank means you can enjoy run times up to 16 hours @ 50% load. (source: Harbor Freight (opens in a new tab))

Zoom on the Predator 4375

In summary, the Predator 4375 is a compact portable generator especially useful for:

  • RV travellers looking for even more independence
  • People occasionally participating in sporting competitions, open-air performances and outdoor festivals
  • Amateur DIY lovers
  • Homeowners who want to be sure of their ability to power their fridges, cooking tools, heating and lighting equipment during power failures
  • Professionals who want to ensure that a power failure will not prevent them from working

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 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.

Enjoying a noise rating of 72 dBA (just slightly more noisy than a dishwasher), this generator gets running thanks to a simple traditional pull-start mechanism.

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

Outlets

The control panel features the following 5 AC outlets:

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

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

As it features a twist-lock L14-30R receptacle, the 4375 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 4375 is a typical, open frame, with the dimensions of L23.3 x W18.7 x H19.3 in, offering support and stability and enabling the possibility of raising it above ground level. The featured design is ideal for the outdoors and all tough environments.

As the generator's weight is 103.5 pounds, manually moving it or transporting it may be challenging, despite the fact that it is technically considered 'portable' (movable). However, its challenging mobility is solved by a wheel kit (separate purchase), which will ease its displacement, once it is on the floor.

Features

The 4375's control panel

When the oil level is too low, 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 automatic low oil shut-off and an overload protection (circuit breaker), allowing you to use it with a peace of mind.

Besides the features previously mentioned, accessory-wise, the Predator 4375 comes with the usual documentation and owner's manual (opens in a new tab) needed to get you promptly started.

Emissions

The Predator 4375 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, so it is adequate for use 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).

  • With a dry weight of 103.5 pounds, the Predator 4375 finds itself in the expected weight range for generators able to produce between 3000 and 4000 rated watts. If you are concerned by weight, one of the champions in the above mentioned power range is the WEN GN400i, with a dry weight of just 66.1 pounds.
  • Among the generators of a comparable running wattage, this generator with a lowest noise of 72 dBA can be judged as noisy. 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 Cat INV4000E, whose lowest noise levels reach just 51 dBA.
  • Since the 4375 boasts with a run time of around 16 hours at 50% load, it can be safely judged as one of the devices with the highest run time among those of a comparable output.
  • Even though run times are undoubtedly important, they are dependent on the fuel capacity to a large extent. For a more wholesome picture, we must take into consideration the fuel consumption of the generator. At an estimated fuel consumption of 0.25 GPH (gallon per hour) at 50% load, this generator is a rather fuel efficient one within its wattage category. If not satisfied with the afore-mentioned fuel consumption, you may wish to check out the Westinghouse iGen4200. With a fuel consumption of as little as 0.17 GPH, it is one of the most efficient generators currently on the market.
