Description

Zoom on the Predator 4400

In a nutshell, the Predator 4400 is a portable inverter generator mostly geared towards:

  • RV travellers looking for even more independence
  • People occasionally participating in sporting competitions, open-air performances and outdoor festivals
  • Handcrafting enthusiasts who wish to work on-the-go
  • Homeowners in need of an emergency backup power for their essentials
  • Camping and tailgating hobbyists looking for a portable power source
  • Professionals who want to be able to deliver results, even during a power failure

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 4400 in use

The Predator 4400

The Predator 4400's design includes a gasoline-fueled 223 cc (6.5 hp) OHV 4-stroke engine. With a 120V output, it gives a running wattage of 3500W and also a peak wattage of 4400W. Moreover, since it is parallel capable (parallel kit not included), its power may be doubled if linked to a second compatible unit.

The inverter generator features a conventional pull-start mechanism. It is rated for a noise of 67 dBA (less noisy than background music).

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

The 4400 produces a clean sine wave: thanks to a <3% Total Harmonic Disruption (THD), your sensitive electronics can be safely plugged in the AC outlets.

Outlets

The control panel includes the following 5 AC outlets:

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

It also sports 2 DC outlets: there's two 5V USB ports (USB-A) allowing you to conveniently charge electronics such as mobile phones and tablets.

This Predator generator isn't quite RV Ready, but it features an L5-30R receptacle, allowing a simple RV connection through an L5-30P to TT-30R adaptor (included).

Portability

The Predator 4400 has a conventional, open frame design, which offers support and allows it to be raised above ground level. This type of design is ideal for tough environments and heavy outdoor use.

The 4400's dry weight of 77 lbs lets you use its power anywhere needed. Moreover, grabbing and moving this product is made even easier by its open frame design.

It is also possible to purchase the official wheel kit (opens in a new tab) to help you transport this unit more easily.

Features

Panel of the Predator 4400

The 4400's control panel

When its oil levels are insufficient, the generator is on overload and the generator is ready, you will be informed by the featured light indicators.

The inverter generator allows for a quick, easy and convenient assessment of its gas level, as it is equipped with a built-in fuel gauge.

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. It’s a welcomed additional security feature, but don’t forget to always take your generator outside (opens in a new tab).

While the standard documentation and an owner's manual (opens in a new tab), helpful for starting the device promptly, come with the Predator 4400, the following accessories are also included: funnel, tool kit and RV adapter.

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.

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 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 generators which produce 3000 to 4000 rated watts. If weight is your top priority, one of the champions in this power category is the WEN GN400i, weighing just 66.1 pounds.
  • Because this inverter generator emits noise as low as 67 dBA, it can be considered to have a pretty average expected noise rating for a device of its power. If noise emissions are important to you, one of the least noisy generators of this power range is the Cat INV4000E with only 51 dBA.
  • The 4400, offering a run time of up to 16 hours with a full tank at a 25% load, falls within the average autonomy range when compared to its peers. Furthermore, considering the run times, one of the generators which have a roughly same power output, with the highest autonomy, is the Champion 200954, as it provides up to 22 hours.
  • Even though run times are undoubtedly important, they are dependent on the fuel capacity to a large extent. For a more wholesome picture, we must take into consideration the fuel consumption of the generator. 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 you are concerned with gasoline efficiency, having a fuel consumption of just 0.13 GPH, the Energizer eZV3500P is a device you should look out for.
According to our stats, the following comparison is pretty popular: Predator 4400 vs Predator 3500.

Price comparison

As you can see from this interactive chart, when compared to other 3000-4000W generators, the Predator 4400 is on the average side of the price range.

Therefore, this generator nicely fits in the expected budget for this kind of product.

    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
    • Microwave low power

    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.

    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.
