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
- Amateur DIY lovers
- Homeowners who want to be able to use the most necessary devices in their household, even during a blackout
- Tailgating and campground aficionados with the desire of enjoying power anywhere they go
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
The Predator 3500's design includes a gasoline-fueled 212 cc (6 hp) OHV 4-stroke engine. With a 120V output, it gives a running wattage of 3000W and also a peak wattage of 3500W. Additionally, as the generator is parallel capable (parallel kit (opens in a new tab) not included), it can be linked to a second unit for more power.
With a noise rating of 56 dBA (less noisy than a refrigerator), the inverter generator features a simple traditional pull-start mechanism, but also a convenient and easy-to-use electric starter (battery included).
With a fuel capacity of 2.64 gallons, the 3500 may run for up to 11 hours with a full tank (fuel consumption around 0.24 GPH).
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:
Additionally, it features 1 DC outlet: there's a 12V 8A receptacle allowing you to easily charge your batteries.
Even if this Predator generator isn't quite RV Ready, it still allows for an easy RV connection via an L5-30P to TT-30R adaptor (included), thanks to its L5-30R receptacle.
Portability
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.
Since the generator weighs 102 lbs, it will be incredibly difficult to manually lift it and transport it, even though it is technically considered to 'be portable' (in the sense that it is movable). Nevertheless, it can still be moved quite conveniently with the help of its set of 4 wheels and its double handle, once it is placed on the ground.
Features
The 3500's control panel
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 power output, voltage and lifetime run hours.
In addition to this info, several light indicators serve to show you when the generator is ready, the generator is overloaded and its oil levels are insufficient.
A built-in fuel gauge allows for a quick, easy and convenient check of the fuel level of the inverter generator.
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. 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, RV adapter and tool kit. 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, which makes it suitable for use 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).
- Having a dry weight of 102 lbs, the Predator 3500 belongs in the expected weight range for inverter generators which produce 2500 to 3500 rated watts. If weight is your top priority, one of the champions in this power category is the Genmax GM3300i, weighing just 47.4 pounds.
- With a lowest noise rating of 56 dBA, the inverter generator is one of the more quiet of the generators of similar type and power. If noise emissions are one of your priorities, you may be interested in the Honda EU3000iS, one of the least noisy generators similarly powerful as this one, rated for 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 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 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 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
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.
