Description

Zoom on the Predator 4400

In summary, the Predator 4400 is a portable inverter generator especially useful for:

  • RV travellers looking for even more independence
  • Occasional participants of outdoor events, competitions, concerts and 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 hobbyists looking for a portable power source
  • Professionals in need of safely powering high-intensity work or lighting equipment

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 4400 in use

The Predator 4400

The Predator 4400 houses a 223 cc (6.5 hp) OHV 4-stroke engine, which provides 120V, consumes gasoline and delivers a running wattage of 3,500W along with a peak wattage of 4,400W. In addition, the device is parallel capable (parallel kit not included) and thus, can be linked to a similar or compatible unit for added power.

With a noise rating of 67 dBA (less noisy than background music), the inverter generator features a simple traditional pull-start mechanism.

With a fuel capacity of 3.2 gallons, the 4400 may run for up to 16 hours with a full tank (fuel consumption around 0.2 GPH).

The 4400 generates a clean sine wave: providing <3% Total Harmonic Distortion (THD), delicate electronics can be plugged in its AC outlets safely.

Outlets

The control panel includes the following 5 AC outlets:

Two Duplexes 120V 20A (5-20R) GFCI
120V 30A (L5-30R) receptacle

Additionally, it features 2 DC outlets: there's two 5V USB ports (USB-A) with which you may charge electronics, for example mobile phones or tablets, conveniently.

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 design of the Predator 4400 is a typical, open frame, offering support and stability and enabling the possibility of raising it above ground level. This type of design is ideal for tough environments and heavy outdoor use.

With a dry weight of 77 lbs, the 4400 can easily follow you wherever your power needs are. Additionally, the generator’s mobility is also improved by its open frame design, as it can be easily grabbed and shifted.

If you wish to transport this unit more easily, you may also consider purchasing the official wheel kit (opens in a new tab).

Features

Panel of the Predator 4400

The 4400's control panel

When the generator is overloaded, the oil level is too low and the generator is ready, you will be informed by the featured light indicators.

A built-in fuel gauge allows for a quick, easy and convenient check of the fuel level of the inverter generator.

As far as security is concerned, the generator can be used with a peace of mind, as it features an automatic low oil shut-off and an overload protection (circuit breaker).

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.

With the basic documentation and an owner's manual (opens in a new tab), letting you start the generator quickly, the Predator 4400 also comes with several accessories, including: RV adapter, funnel and tool kit.

Emissions

The Predator 4400 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, so it is adequate for use in forested areas.

Product Videos

The Predator 4400 versus other generators

The following charts are provided to give you an idea of how some of the key specs of the Predator 4400 compare to inverter generators of similar power (between 3000 and 4000 W).

  • Weight-wise, the Predator 4400 has only 77 lbs, which renders it one of the lighter inverter generators which produce 3000 to 4000 rated watts. If weight is your top priority, one of the champions in this power category is the Pulsar PGD40iSCO, weighing just 46 pounds.
  • As this inverter generator has its lowest possible noise of 67 dBA, it should be considered noisier compared to its peers of a comparable running wattage. If noise emissions are important to you, one of the least noisy generators of this power range is the Westinghouse iGen4500DF with only 52 dBA.
  • Offering up to 16 hours of running time on a full tank at 25% load, the 4400 is within the average autonomy range of similarly powerful inverter generators. If you consider autonomy on a single full tank as one of the deciding factors, one of the generators in the same power range that offers the highest run time is the Firman W03661OF, with up to 25 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. This inverter generator has an average fuel consumption among comparably powerful devices, as it reaches 0.2 GPH (gallon per hour) 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.
According to our stats, the following comparison is pretty popular: Predator 4400 vs Predator 3500.

    Will only run AC in 2011 elkridge RV fifth wheel very few other items can’t even use the converter in the RV when the microwave is running or vice versa can’t use the refrigerator if the converter is running it’s got to be on propane so to me this generator inverter is a piece of garbage I don’t know how harbor freight and even sell it especially when the motor quits working in less than 3 months it Has no compression and will not start to me this generator inverter is a piece of junk motor sucks

    + PROS:
    • None
    - CONS:
    • Had in less than 3 months won't run RV will only run AC by itself nothing else motor lost all compression in less than 3 months won't even start

    This has been a great little generator. It has powered my grand design reflection with no problem and that includes the a/c.

    + PROS:
    • Super quiet. Ran non stop for 3 days turned off only to fill up fuel. Powered everything in my camper including 15000 BTU a/c. I will say though, if you forget to flip the throttle switch it will not run the a/c.
    - CONS:
    • None yet. I’ve had it for 3 months now.

    Like many others have found, it will NOT power a 13,500 BTU a/c even though it is advertised to do so. Bought for exclusive RV use. Have bigger unit for home use so this Predator is basically useless. H/F 20% restock fees suck even when products don’t do the job that they are advertised to do.

    + PROS:
    • Easy start. Engine strong.
    - CONS:
    • As stated in review.

    Big let down.it would not power 1500 watt Ac unit in my 2012 keystone camper. I borrowed one of my friends 4000 why generator and it had no problem whatsoever, After I ran it for a week because it was chilly the motor started to rattle and shake the whole housing in Rab open down in the exhaust muffler became Extremely loose and a few screws came out dropping the motor

    + PROS:
    • Rv plugs
    - CONS:
    • Wouldn’t power ac unit
