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 sporting competitions, open-air performances and outdoor festivals
  • DIYers who wish to improve their efficiency with tools
  • 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

In the following paragraphs, we shall explore the power characteristics, available outlets, portability, and any additional features of the device, along with its emission compliance information.

Power & Run Time

The Predator 3500 in use

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 3,000W and also 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 a conversation at home), 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.

The 3500 produces a clean sine wave: thanks to a <5% Total Harmonic Distortion (THD), your sensitive electronics can be safely plugged in the AC outlets.

Outlets

The control panel provides the upcoming 3 AC outlets:

Duplex 120V 20A (5-20R)
120V 30A (L5-30R) receptacle

In addition, it provides 1 DC outlet: there's a 12V 8A receptacle with which charging your batteries is made easy.

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.

Portability

As the Predator 3500 is an inverter generator, its encased design (L22.8 x W17.3 x H20 in) offers more aesthetics than a conventional, open frame product. 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

Panel of the Predator 3500

The 3500's control panel

A digital data center, one of the features of the 3500's control panel, gives you information on the voltage, lifetime run hours and power output, 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 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 for its security measures, the device features an automatic low oil shut-off and an overload protection (circuit breaker), letting you 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.

Apart from the typical documentation and an owner's manual (opens in a new tab), which lets you start it right away, the Predator 3500 also is packed along with the following accessories: funnel, tool kit, battery charging cables 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 therefore, can 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).

  • A weight of 102 lbs makes the Predator 3500 one of the heavier inverters in the 2500-3500 rated wattage range. If weight matters to you, one of the champions in this power range is the Pulsar PGD40iSCO with only 46 pounds.
  • 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.
  • As far as autonomy is concerned, providing up to 11 hours of runtime with a full tank at a 25% load, the 3500 falls into the low end in comparison with other inverters of a comparable power output. 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.
  • Run times are important, yet thanks to their dependence on the fuel capacity, they should be judged along with the fuel consumption of the device. Compared to its peers, this inverter generator is not exactly fuel efficient, compared to similarly powerful devices, with an estimated fuel consumption of 0.24 GPH at a 25% load. If fuel consumption is your top priority, we suggest to check out the Energizer eZV3500P, which has a fuel consumption of only 0.13 GPH and thus, is one of the most efficient devices in our database.

Price comparison

As you can see from these interactive charts, 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.

    Off grid cabin power. Runs 1500 watt heater and 1000w microwave easily. Plus all the lights and power devices I’d normally use at home. Will add a portable a/C unit eventually. Had in use for past 4mos with no problems. Been using 91 octane non-ethanol gas with a stabilizer. Only due to requirements of the 2yr purchased warranty. Replaced the spark plug with an NGK out of the box before I even started it. I built a open ended box to protect against weather. Stays outdoors and is surrounded by mouse poison and such. So far so good.

    + PROS:
    • Runs 12+ hrs on tank of gas.
    • Easy starting
    • Easy maintenance
    • HF is easy to work with for any problems
    - CONS:
    • None that I have issues with.

    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.

    + PROS:
    • Reliable
    • Quiet
    • Power output over the advertised spec
    - CONS:
    • Minor component failure

    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

    + PROS:
    • Works great when running!
    - CONS:
    • NOT WEATHER PROOF! Rain shorts the sensors leaving the generator useless for a few days but works great when you don't absolutely need it.

    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.

    + PROS:
    • Quiet.
    • Cost efficient compared to other bigger brands.
    • Starts right up every time.
    • Reliable.
    - CONS:
    • Wheel lock rattles but fixable.

    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.

    + PROS:
    • Value, ease of starting and performance.
    - CONS:
    • Internal battery must have a disconnect switch added.

    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.

    + PROS:
    • Nice looking with many features.
    - CONS:
    • Failed for no reason with little use after 10 months. Less than 15 hours on it . New unit given to replace this to be sold soon.

    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.

    + PROS:
    • Has been 100% reliable
    • Quiet
    • Rolls easily across hard surfaces
    • Twist-Lock Receptacle
    - CONS:
    • High fuel consumption
    • Exhaust smells of unburned fuel
    • No fuel gauge

    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!

    + PROS:
    • Great price
    • Reliable work horse
    • Fairly quiet
    • Long lasting
    - CONS:
    • Used pull start 2 times and the cord broke

    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.

    + PROS:
    • Price was outstanding
    • It's very quiet
    • Fits inside trailer door when hauling (Not Too Wide)
    • Battery and Pull start both work well
    • Out performed expectations for a Harbor freight item
    • It has handled everything i have asked it to do while dry camping.
    - CONS:
    • Wheels
    • No Low fuel indicator

    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.

    + PROS:
    • Inexpensive compared to similar inverter generators.
    • Because it’s an inverter it can safely charge an electric vehicle (slowly)
    • Quiet
    • Light weight (for output capacity).
    • Plenty of available modifications (remote start, natural gas/propane adapter)
    - CONS:
    • The wheels are hard plastic, very small. Makes moving it anywhere a bit awkward.
    • No external fuel gauge.

    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.

    + PROS:
    • Size and weight, quiet and affordable, if you maintain it and run monthly, it is extremely reliable. Many support groups and parts are easily available.
    - CONS:
    • Fuel efficiency, remote start not included, spark plug it comes with is weak, fuel tank can only be filled to 80%.
