Description
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
- DIYers who wish to improve their efficiency with tools
- Homeowners who want to be able to use the most necessary devices in their household, even during a blackout
- Professionals in need of safely powering high-intensity work or lighting equipment
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 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.
The 4375 can operate for around 16 hours at 50% load with a full tank (fuel consumption around 0.25 GPH), due to its fuel capacity of 4 gallons.
Outlets
The control panel provides the upcoming 5 AC outlets:
Furthermore, it has 1 DC outlet: there's a 12V 8A (cigarette lighter style) receptacle allowing you to easily charge your batteries.
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 Predator 4375 has the following dimensions: L23.3 x W18.7 x H19.3 in. In combination with its conventional, open frame design, they provide support and allow the generator to be raised above ground level. This type of design is ideal for tough environments and heavy outdoor use.
Even though this device may be technically portable (as in movable), manipulation and transportation without special equipment can be a challenge, as it weighs 103.5 pounds. However, this lack of maneuverability is compensated by a wheel kit (separate purchase), with which you can conveniently shift it, once it's on the ground.
Features
A light indicator shows you if the oil level is too low.
The fuel level of the generator can be determined quickly, easily, and conveniently with the help of its built-in fuel gauge.
As for its security measures, the device features an overload protection (circuit breaker) and an automatic low oil shut-off, letting you use it with a peace of mind.
As for its accessories, apart from the previously mentioned features, the Predator 4375 also comes with the basic documentation and an owner's manual (opens in a new tab), allowing you to start it right away.
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, making it usable in forested areas.
Product Videos
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).
- Since the generator weighs in at a dry weight of 103.5 lbs, the Predator 4375 belongs in the expected weight range for devices which can produce between 3000 and 4000 rated watts. Regarding dry weight, one of the champions in the same power range is the WEN GN400i, with a dry weight of only 66.1 lbs.
- If compared to generators capable of producing a similar running wattage, this generator with a lowest emitted noise of 72 dBA can be considered somewhat 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.
- With a run time of around 16 hours at 50% load, the 4375 has one of the highest run times, compared to its similarly powerful peers.
- 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. This generator, with an estimated fuel consumption of just 0.25 GPH (gallon per hour) at 50% load, is one of the more fuel efficient generators, for the previously mentioned wattage range. If you wish to acquire one of the most gasoline efficient products of this power range, the Westinghouse iGen4200, with a fuel consumption of 0.17 GPH could be in your good books.
Price comparison
As you can see from this interactive chart, when compared to other 3000-4000W generators, the Predator 4375 is on the cheap side of the price range.
It can therefore be a really good buy if you're looking to acquire a budget generator.
The bottom line
- Inexpensive
- GFCI Outlets
- High run time
- Fuel efficient
- Decent weight (103.5 lbs)
- No data center
- No electric start
- Wheel kit not included
- Weak warranty
- On the noisy side (72 dBA)

Love this product, always wanted to own. Generator and this one was perfect for the price and accessibility.
I bought the generator wheel kit. I watched a video about the generator. In the video, the man said he’d originally put the wheel mounts on backwards. I looked at the instructions. I tried to determine how to attach the wheel mounts. The kit didn’t come with the correct washers. I couldn’t attach the mounts with the provided washers. I wanted to put washers on both sides of the wheels. That’s what the directions show. I have lots of spare nuts, washers, etc. Unfortunately, didn’t have what was necessary. I had to make a run to the hardware store.
I agree that the oil fill is in a poor location. The generator seems well built. Hopefully, I’ll get many years of use out of it.
Bought the generator as a backup power source for our home. Had to buy a wheel kit, but it was easy to install. Wished it had a data center, but I bought one via AMAZON. Hooked the generator to the house panel after having the panel fitted for it. The generator works perfectly in powering everything except the central air, it would power the central heat though. Overall…very happy with the purchase!
Gfi outlets trip continuously while running only 7 amps!! Cannot replace existing 110 ac gfi outlets on the control panel. I have an 1800 Ironton generator that will run the same 7 amp equipment all day long!! I would not recommend purchasing a predator 4375 Generator!!
