Zoom on the Predator 3500

In a nutshell, the Predator 3500 is a quiet and compact portable inverter generator mostly geared towards:

  • RV travellers who wish to upgrade their experience to another level
  • 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 sure of their ability to power their fridges, cooking tools, heating and lighting equipment during power failures
  • Tailgating and campground aficionados with the desire of enjoying power anywhere they go

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 3500 in use

The Predator 3500

The Predator 3500 houses a 212 cc OHV 4-stroke engine, which provides 120V, consumes gasoline and delivers a running wattage of 3000W along with a peak wattage of 3500W. In addition, as it is parallel capable (parallel kit (opens in a new tab) not included), this power can be doubled when linked to another similar or compatible unit.

Enjoying a noise rating of 57 dBA (less noisy than a refrigerator), this inverter generator can be started thanks to a conventional pull-start mechanism, but also to a simple and elegant electric starter (battery included).

The 3500 can operate for up to 11 hours with a full tank (fuel consumption around 0.24 GPH), due to its fuel capacity of 2.6 gallons.

Sensitive electronics can be safely plugged in the AC outlets, as the 3500 produces a clean sine wave, with a <5% Total Harmonic Disruption (THD).

Outlets

The control panel includes the following 3 AC outlets:

Duplex 120V 20A (5-20R)
120V 30A (L5-30R) receptacle

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

While this Predator generator is not RV Ready, its L5-30R receptacle can be used for a simple RV connection with an L5-30P to TT-30R adaptor (included).

Portability

Thanks to its closed inverter generator design (L22.8 x W17.3 x H20 in), the Predator 3500, is more esthetical than a typical, open frame generator. This modern design aims to provide an ideal power solution to recreational users.

The 3500 can be taken anywhere with you, thanks to its weight of 99.2 lbs. Moreover, its set of 4 wheels and its double handle will allow you to effortlessly shift it once it's on the ground.

Features

Panel of the Predator 3500

The 3500's control panel

A digital data center, one of the features of the 3500's control panel, gives you information on the voltage, lifetime run hours and power output, and thus, is helpful for the monitoring of its activity and status.

In addition to this info, the light indicators show you if the generator is ready, its oil levels are insufficient and the generator is on overload.

From a security point of view, the generator is equipped with an overload protection (circuit breaker) and an automatic low oil shut-off, giving you a peace of mind during use.

Apart from the typical documentation and an owner's manual (opens in a new tab), which lets you start it right away, the Predator 3500 also is packed along with the following accessories: funnel, tool kit, RV adapter and battery charging cables. A storage cover is also available, as a separate purchase.

Emissions

The Predator 3500 is EPA-approved and CARB-compliant. Therefore, its sale and purchase are permitted in all of the 50 states, including California.

Moreover, it features a spark arrestor and thus, may be used in forested areas.

The Predator 3500 versus other generators

The following charts are provided to give you an idea of how some of the key specs of the Predator 3500 compare to generators of similar power (between 2500 and 3500 W).

  • As its weight is 99.2 pounds, the Predator 3500 falls in the expected weight range of the devices in the 2500-3500 rated wattage category. Regarding dry weight, one of the champions in the same power range is the Generac GP3300i, with a dry weight of only 59.5 lbs.
  • At a lowest noise rating of 57 dBA, this inverter generator is one of the quieter devices of similar power. If noise emissions are important to you, one of the least noisy generators of this power range is the Honda EU3000iS with only 50 dBA.
  • As far as autonomy is concerned, providing up to 11 hours of runtime with a full tank at a 25% load, the 3500 falls into the low end in comparison with other devices of a comparable power output. If autonomy is your priority, one of the devices of a similar power output with the highest run time is the Champion 200954, reaching up to 22 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 inverter generator is rather wasteful, compared to other devices within the aforementioned output range, when it comes to gasoline consumption, as it reaches roughly 0.24 GPH at a 25% load. If you are concerned with gasoline efficiency, having a fuel consumption of just 0.13 GPH, the Energizer eZV3200P is a device you should look out for.

Price comparison

As you can see from this interactive chart, when compared to other 2500-3500W generators, the Predator 3500 is on the average side of the price range.

Therefore, this generator nicely fits in the expected budget for this kind of product.

    Predator 3500 has been a great solution for me for 4 years of camping and home emergency use. I run it monthly and use stabil in the gas. I added the remote start option which is nice to start it up for morning coffee before having to go outside. It powers 2 AC units in my RV with Soft Start RV installed.

    + PROS:
    • Size and weight, quiet and affordable, if you maintain it and run monthly, it is extremely reliable. Many support groups and parts are easily available.
    - CONS:
    • Fuel efficiency, remote start not included, spark plug it comes with is weak, fuel tank can only be filled to 80%.

    This thing is an excellent generator for emergency or camping. Because it is so (relatively) quiet. When running an adequate load, think quieter than a lawnmower and louder than a box fan. The readout is simple to understand and the push start is excellent (also has a pull start if you need it). As many online forums mention, it’s recommended to run on ethanol-free fuel, change the oil after the first hour of use (to remove lose debris from engine), and get a magnet oil-cap to help remove shards of metal (best practice for any generator). You won’t find a better value on an inverter.

    + PROS:
    • Inexpensive compared to similar inverter generators.
    • Because it’s an inverter it can safely charge an electric vehicle (slowly)
    • Quiet
    • Light weight (for output capacity).
    • Plenty of available modifications (remote start, natural gas/propane adapter)
    - CONS:
    • The wheels are hard plastic, very small. Makes moving it anywhere a bit awkward.
    • No external fuel gauge.

    This is my first dry camping generator Purchased in late 2018. This Predator inverter generator has been great. It has started every time via starting switch or pull start. I have ran 92 octane fuel in it and so far haven’t had any issues with not running it for a month to 4 months. Longest stretch not running is between mid November and the end of March. I am very happy with this product and will be installing a tri fuel kit soon.

    + PROS:
    • Price was outstanding
    • It's very quiet
    • Fits inside trailer door when hauling (Not Too Wide)
    • Battery and Pull start both work well
    • Out performed expectations for a Harbor freight item
    • It has handled everything i have asked it to do while dry camping.
    - CONS:
    • Wheels
    • No Low fuel indicator

    This is the first generator I’ve ever bought or used frequently so I don’t know to much about the longevity of these machines but I have to say this little monster is a workhorse! We use it every day, all day long, and sometimes day and night for weeks straight! I currently have 4951 hours of run time on it so far and I don’t know if that’s high for this generator or not but I’m impressed! It is starting to show wear. But I’ll buy another one just like it!

    + PROS:
    • Great price
    • Reliable work horse
    • Fairly quiet
    • Long lasting
    - CONS:
    • Used pull start 2 times and the cord broke
