Zoom on the Predator 3500
In summary, the Predator 3500 is a quiet and compact portable inverter generator especially useful for:
- RV travellers looking for even more independence
- People occasionally participating in outdoor fairs, festivals or events
- Handcrafting enthusiasts who wish to work on-the-go
- Homeowners who want to be sure of their ability to power their fridges, cooking tools, heating and lighting equipment during power failures
- Camping and tailgating buffs looking to enhance their experience
The following sections will present you in detail its power characteristics, the different outlets it offers, its overall portability, the extra features it benefits from, and any relevant emission compliance details.
Power & Run Time
The Predator 3500's core is the 212 cc (6 hp) OHV 4-stroke engine, which runs on gasoline. With an output of 120V, it provides a running wattage of 3,000W and a peak wattage of 3,500W. 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.
Enjoying a noise rating of 56 dBA (less noisy than rainfall), this inverter generator can be started thanks to a conventional pull-start mechanism, but also to a convenient and easy-to-use electric starter (battery included).
With a full tank, the 3500 can operate for up to 11 hours (fuel consumption around 0.24 GPH), thanks to its fuel capacity of 2.64 gallons.
Delicate electronics can be plugged in an AC outlets safely, as the 3500 generates a clean sine wave, reaching a <5% Total Harmonic Distortion (THD).
The control panel features the following 3 AC outlets:
In addition, it provides 1 DC outlet: there's a 12V 8A receptacle with which you may charge your batteries with ease.
This Predator generator features an L5-30R receptacle, enabling an easy RV connection via an L5-30P to TT-30R adaptor (included). However, it is still not quite RV ready.
Since the Predator 3500 is an inverter generator, its closed design (L22.8 x W17.3 x H20 in) has an esthetical advantage over conventional, open frame devices. The generator has a contemporary design, convenient for recreationally generating power.
Even though this device may be technically portable (as in movable), manipulation and transportation without special equipment can be a challenge, as it weighs 102 pounds. Still, once it is on the ground, its set of 4 wheels and its double handle can easily solve the issue of low mobility and allow for easy relocation of the device.
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 voltage, lifetime run hours and power output.
In addition to this info, the light indicators show you if the oil level is too low, the generator is overloaded and the generator is ready.
The inverter generator includes a built-in fuel gauge, a quick, easy and convenient method of checking the device’s gas level.
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).
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: funnel, tool kit, battery charging cables and RV adapter are included. 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 and thus, may be used in forested areas.
The unit also meets the ANSI/PGMA G300-2018 safety and performance requirements.
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 inverter generators of similar power (between 2500 and 3500 W).
- Since the generator weighs in at a dry weight of 102 lbs, the Predator 3500 belongs in the expected weight range for inverters which can produce between 2500 and 3500 rated watts. Regarding dry weight, one of the champions in the same power range is the Pulsar PGD40iSCO, with a dry weight of only 46 lbs.
- With a lowest possible noise of 56 dBA, this inverter generator places itself amongst the more quiet of the products delivering 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 type and power range, as it reaches only up to 11 hours at 25% load on a full tank. Concerning the run times, one of the several devices with a comparable output, offering the highest autonomy, is the Champion 200914, which is able to run for up to 22 hours.
- 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 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 eZV3500P is a device you could look out for.
Here's a list of the most popular specific comparisons:
As you can see from this interactive chart, when compared to other 2500-3500W inverter 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.
