Zoom on the Predator 4000
In a nutshell, the Predator 4000 is a compact portable generator mostly geared towards:
- RV travellers who wish to upgrade their experience to another level
- People occasionally participating in outdoor fairs, festivals or events
- 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 4000
The Predator 4000 is powered by a 212 cc (6.5 hp) OHV 4-stroke engine. It delivers 120/240V, runs on gasoline and offers a running wattage of 3200W as well as a peak wattage of 4000W.
With a noise rating of 72 dBA (just slightly more noisy than a shower), the generator features a conventional pull-start mechanism.
The 4000 can operate for around 10 hours at 50% load with a full tank (fuel consumption around 0.4 GPH), due to its fuel capacity of 4 gallons.
Outlets
The control panel provides the upcoming 5 AC outlets:
In addition, it provides 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 4000 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 dimensions of the Predator 4000, 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.
The 99.5 lbs of the 4000's dry weight enables you to use it anywhere you will ever need. Additionally, the generator’s mobility is also improved by its open frame design, as it can be easily grabbed and shifted.
It is also possible to purchase a wheel kit, such as this one (opens in a new tab), to help you transport this unit more easily.
Features
The 4000's control panel
A light indicator serves to show you when the oil level is too low.
Thanks to a built-in fuel gauge, the 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.
Besides the features previously mentioned, accessory-wise, the Predator 4000 comes with the usual documentation and owner's manual (opens in a new tab) needed to get you promptly started.
Emissions
The Predator 4000 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.

The Predator 4000 versus other generators
The following charts are provided to give you an idea of how some of the key specs of the Predator 4000 compare to generators of similar power (between 2500 and 3500 W).
- Since the generator weighs in at a dry weight of 99.5 lbs, the Predator 4000 belongs in the expected weight range for devices which can produce between 2500 and 3500 rated watts. If weight matters to you, one of the champions in this power range is the Generac GP3300i with only 59.5 pounds.
- When compared to devices able to produce a similar running wattage, this generator and its lowest emitted noise of 72 dBA is on the noisier side. 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 Honda EU3000iS, whose lowest noise levels reach just 50 dBA.
- The 4000, offering a run time of around 10 hours with a full tank at a 50% load, falls within the average autonomy range when compared to its peers. If you consider autonomy on a single full tank as one of the deciding factors, one of the generators in the same power range that offers the highest run time is the Predator 4375, with around 16 hours.
- 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. This generator is rather wasteful, compared to other devices within the aforementioned output range, when it comes to gasoline consumption, as it reaches roughly 0.4 GPH at a 50% load. 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.
Here's a list of the most popular specific comparisons:
Price comparison
As you can see from this interactive chart, when compared to other 2500-3500W generators, the Predator 4000 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
- Decent weight (99.5 lbs)
- Decent run time
- No data center
- No electric start
- Weak warranty
- On the noisy side (72 dBA)
- Low fuel efficiency

i have had a predator 400 for about 4 years. however at this time, the plugs do not work, the resets do not work and when the front panel was taken off to be looked at, the plug casing was broken, only on one side, the other side was cracked. teh resets were replaced, but that did not solve the problem. i have been thru 2 hurricanes and a couple of other power outages. i work on fence lines and where i go hunting. great tool. i need the panel or i hve a 99.5 pound noise maker. can you help me
I’ve had my Predator 4000 for about 3 years and it has done it’s job each time. I’ve had 3 significant power outages, one lasted 2+ days. If you run it as recommended and take time to perform PM on it it’s a nice unit to save your frozen goods plus a few lights and TV.
