- Amateur DIY lovers
- Homeowners who want to be able to use the most necessary devices in their household, even during a blackout
- Camping and tailgating buffs looking to enhance their experience
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 3500's engine, 212 cc (6 hp) OHV 4-stroke, fueled by gasoline, can deliver 120V. It provides a running wattage of 3000W and reaches a peak wattage of 3500W. In addition, the device is parallel capable (parallel kit (opens in a new tab) not included) and thus, can be linked to a similar or compatible unit for added power.
With a noise rating of 56 dBA (less noisy than a quiet suburb), the inverter generator features a conventional pull-start mechanism, but also a convenient and easy-to-use 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 2.64 gallons.
The 3500 produces a clean sine wave: thanks to a <5% Total Harmonic Disruption (THD), your sensitive electronics can be safely plugged in the AC outlets.
The control panel provides the upcoming 3 AC outlets:
Additionally, it features 1 DC outlet: there's a 12V 8A receptacle with which charging your batteries is made easy.
Even though this Predator generator isn't quite RV Ready, its L5-30R receptacle allows an easy RV connection via an L5-30P to TT-30R adaptor (included).
The Predator 3500 is an inverter generator and has an encased design of the following dimensions: L22.8 x W17.3 x H20 in. Thus, it is more aesthetical than conventional, open frame products. The generator has a contemporary design, convenient for recreationally generating power.
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 102 lbs. However, its challenging mobility is solved by its set of 4 wheels and its double handle, which will ease its displacement, once it is on the floor.
The control panel of the 3500 includes a digital data center, which assists you in monitoring its status and activity, as it provides information on the lifetime run hours, power output and voltage.
In addition to this info, some light indicators allow you to instantly see if the generator is on overload, its oil levels are insufficient and the generator is ready.
A built-in fuel gauge allows for a quick, easy and convenient check of the fuel level of the inverter generator.
As far as security is concerned, the generator can be used with a peace of mind, as it features an overload protection (circuit breaker) and an automatic low oil shut-off.
The unit also benefits from the Predator's CO SECURE™ carbon monoxide detection. This system monitors the accumulation of CO gas while the generator is running and will shut off the engine if the levels become dangerously high. It’s a welcomed additional security feature, but don’t forget to always take your generator outside (opens in a new tab).
With the basic documentation and an owner's manual (opens in a new tab), letting you start the generator quickly, the Predator 3500 also comes with several accessories, including: battery charging cables, funnel, tool kit and RV adapter. A storage cover is also available, as a separate purchase.
The Predator 3500 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 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).
- With a dry weight of 102 pounds, the Predator 3500 finds itself in the expected weight range for generators able to produce between 2500 and 3500 rated watts. In terms of weight, one of the champions in their power range is the Genmax GM3300i, standing at just 47.4 lbs.
- With a lowest possible noise of 56 dBA, this inverter generator places itself amongst the more quiet of the products delivering 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.
- Regarding its autonomy, the autonomy of the 3500, reaching up to 11 hours at a 25% load, can be considered as low end, compared to other products of a roughly equal output. If autonomy is your priority, one of the devices of a similar power output with the highest run time is the Champion 200914, 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 wish to further improve in the area of fuel efficiency, the Energizer eZV3500P, which boasts with a gas consumption of only 0.13 GPH, may be the right generator for you.
Here's a list of the most popular specific comparisons:
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.
