Zoom on the Predator 3500
In a nutshell, the Predator 3500 is a quiet and compact portable inverter generator mostly geared towards:
- RV travellers wishing to enhance their freedom and nomad lifestyle
- People occasionally participating in outdoor fairs, festivals or events
- Amateur DIY lovers
- Homeowners in need of an emergency backup power for their essentials
- Camping and tailgating buffs looking to enhance their experience
Power & Run Time
The Predator 3500 houses a 212 cc (6 hp) OHV 4-stroke engine, which provides 120V, consumes gasoline and delivers a running wattage of 3000W along with a peak wattage of 3500W. Moreover, since it is parallel capable (parallel kit (opens in a new tab) not included), its power may be doubled if linked to a second compatible unit.
The inverter generator features a conventional pull-start mechanism and also a simple and elegant electric starter (battery included). It is rated for a noise of 57 dBA (less noisy than a refrigerator).
With a full tank, the 3500 can operate for up to 11 hours (fuel consumption around 0.22 GPH), thanks to its fuel capacity of 2.46 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 features the following 3 AC outlets:
Additionally, it features 1 DC outlet: there's a 12V 8A receptacle allowing you to easily charge your batteries.
This Predator generator isn't quite RV Ready, but it features an L5-30R receptacle, allowing a simple RV connection through an L5-30P to TT-30R adaptor (included).
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. The generator has a contemporary design, convenient for recreationally generating power.
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.
A digital data center, one of the features of the 3500's control panel, gives you information on the power output, lifetime run hours and voltage, and thus, is helpful for the monitoring of its activity and status.
In addition to this info, the device’s light indicators will display if its oil levels are insufficient, the generator is ready and the generator is overloaded.
The fuel level of the inverter generator can be determined quickly, easily, and conveniently with the help of its built-in fuel gauge.
Security-wise, this product benefits from an overload protection (circuit breaker) and an automatic low oil shut-off, which gives you a complete peace of mind when using it.
Besides the classic documentation and an owner's manual (opens in a new tab) to get you promptly started, the Predator 3500 also comes with some accessories: RV adapter, battery charging cables, tool kit and funnel are included. A storage cover is also available, as a separate purchase.
The Predator 3500 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 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).
- Since the generator weighs in at a dry weight of 99.2 lbs, the Predator 3500 belongs in the expected weight range for devices which can produce between 2500 and 3500 rated watts. 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. For those who are looking for a less noisy device, we suggest the Honda EU3000iS. With just 50 dBA, it is one of the most quiet devices in this power range.
- The 3500's autonomy is somewhat low end compared to devices of its power range, as it reaches only up to 11 hours at 25% load on a full tank. Furthermore, considering the run times, one of the generators which have a roughly same power output, with the highest autonomy, is the Champion 200954, as it provides 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 somewhat less fuel efficient than devices of comparable output: its estimated fuel consumption reaches 0.22 GPH at a 25% load. If you wish to acquire one of the most gasoline efficient products of this power range, the Energizer eZV3500P, with a fuel consumption of 0.13 GPH could be in your good books.
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.
