Description
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 in need of an emergency backup power for their essentials
- 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 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. 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.
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 56 dBA (less noisy than a conversation at home).
The fuel capacity of 2.64 gallons allows the 3500 to operate for up to 11 hours with a full tank (fuel consumption around 0.24 GPH).
The 3500 generates a clean sine wave: providing <5% Total Harmonic Distortion (THD), delicate electronics can be plugged in its AC outlets safely.
Outlets
The control panel features the following 3 AC outlets:
Furthermore, it has 1 DC outlet: there's a 12V 8A receptacle with which you may charge your batteries with ease.
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. The featured design follows the latest trends and is ideal for easy and recreational use.
As the generator's weight is 102 pounds, manually moving it or transporting it may be challenging, despite the fact that it is technically considered 'portable' (movable). Nevertheless, thanks to its set of 4 wheels and its double handle (a decent solution to its lack of maneuverability), the generator can be easily moved, once placed the ground.
Features
To help you monitor the 3500's status and activity, its control panel is equipped with a digital data center, giving you information on the voltage, power output and lifetime run hours.
In addition to this info, some light indicators allow you to instantly see if the generator is ready, the oil level is too low and the generator is overloaded.
Thanks to a built-in fuel gauge, the inverter generator allows you to quickly, conveniently and easily check the gas level at a glance.
From a security standpoint, the product offers an overload protection (circuit breaker) and an automatic low oil shut-off, allowing you to use it with a peace of mind.
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.
Along the basic documentation and an owner's manual (opens in a new tab), useful for starting the generator right away, the Predator 3500's package also includes these accessories: funnel, battery charging cables, tool kit and RV adapter. A storage cover is also available, as a separate purchase.
Emissions
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.
Product Video
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).
- Considering its dry weight of 102 pounds, the Predator 3500 is one of the heavier inverter generators producing between 2500 and 3500 running 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.
- 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 inverters of a roughly equal output. Furthermore, considering the run times, one of the generators which have a roughly same power output, with the highest autonomy, is the Champion 200914, as it provides up to 22 hours.
- Autonomy holds its importance, however, it is largely dependent on the generator’s fuel capacity and so, it is nonsensible to discuss it without mentioning fuel efficiency as well. This inverter generator is not fuel efficient compared to devices of similar output: its estimated fuel consumption stands at 0.24 GPH at a 25% load. If not satisfied with the afore-mentioned fuel consumption, you may wish to check out the Energizer eZV3500P. With a fuel consumption of as little as 0.13 GPH, it is one of the most efficient generators currently on the market.

User Reviews
On,y two issues in 4 years use is the output meter died (HF sent a replacement, no hassle) and the battery’s lives have been short, regardless of the make of battery I’ve used. Minor inconveniences.
Major upsides are fast, reliable startups, the fact it powers both my RV A/C units (with soft starters), charges my power stations and my house when power goes out (Florida hurricanes), and is the quietest generator in its class.Running at high output it might be the quietest ever. But Hondas idle w slightly less noise.
Purchased a year ago been using it in Florida, found out it is NOT weather proof. Guess you’re expected to run it indoors and asphyxiate your family or something. The rain shorts out the sensors and it needs to dry out for a few days before it works again. Good luck
I picked up one of these barely used for a very good price and I’ll have to say I’m very impressed by this generator, it’s very quiet and seems to be efficient, had to replace the carburetor because the eco idle didn’t work (bad stepper motor) and a new carb was cheap enough to replace, I also replaced the jet with one appropriate for my elevation. They use 1 size jet (75) for all carburetors even in the new replacement, It now runs better and doesn’t smell rich anymore. Haven’t run it since I replaced the old carb and jet for a extended period of time. Others who have done the same experience longer run times on a tank of gas so I’m sure I’ll experience the same.
The generator battery will self deplete in about one month. I have a 3500. The internal battery was dead after 30 days of no use. Measurements showed that the generator has a 570uA parasitic load on the battery when it is not running. I little math will show that the battery will be depleted by at least 50% if it is stored for 20 days without running. The sealed 12V 7AH battery will not accommodate repeated depletion without damaging the battery. You will want to add a battery disconnect switch if you do not run the generator often. Walmart sells the battery for about $80. This is another example of Chinese engineering. Otherwise the 3500 is a good value.
Bought this back in November 2020 for the home IF we needed it. Ran fine and was quiet. Shut off and put away. Started / shut it over every 2-3 weeks, running it for 10 minutes or more while using ON/OFF and table grinder. Fast forward to August 2021. Go to start as usual. It WILL NOT START. Checked all the usual stuff – Gas in tank, drained gas from carb to check for bad gas, checked for spark. Still won’t start. Decided to check the carb. Looked OK. Cleaned anyway. Same thing. I did purchase the protection plan when I bought it, so back it went. I got a no hassle swap for a new one, which I don’t plan on opening and will end up selling. While I was impressed when I first got it. my trust in it when I truly may need it is damaged. Up for sale it goes. Looking to buy a Honda for peace of mind. Won’t have all the bells and whistles this one does but I am OK with that. I want reliability.
Bought this 4 years ago and it has 200 hours on it. Runs a 30 amp camper when the power goes out, which is rather often, needed it 2 days ago and a week before that. Twist lock receptacle, which is a must-have. Very quiet when lightly loaded but noisier at half load. Fuel efficiency is very low. Uses a whole gallon of gas to heat 10 gallons of hot water, I’ve done this at least 50 times. No way to check the fuel level without removing both the cap and strainer, you get gas on your fingers and it runs dry occasionally. Never had a problem but the engine runs rich. The exhaust stinks of unburned fuel, for this reason I would not buy another. But it was low cost and has been trouble-free. Oil change is relatively easy. Still using it, but purchased a Champion propane generator which is totally safe to store indoors because there is no gasoline in it. This one must live outdoors in the shed.
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!
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.
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.
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.
Costs too much. Weighs too much. Needle valve sticks. Don’t know if it’s compatible to charge Tesla Model 3. It is not dual fuel. No weatherproof housing option.
