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
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:
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
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.
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 generators of similar power (between 3000 and 4000 W).
- In terms of its dry weight, the Predator 4400 stands at only 77 lbs, meaning that is one of the lighter devices of the 3000-4000 rated wattage category If weight matters to you, one of the champions in this power range is the Genmax GM3300i with only 47.4 pounds.
- As this inverter generator can emit noise as low as 67 dBA, it finds itself in the average expected noise for this kind of power. For those who are looking for a less noisy device, we suggest the Cat INV4000E. With just 51 dBA, it is one of the most quiet devices in this power range.
- The 4400, falls within the average autonomy range compared to generators of a roughly same power, with a run time of up to 16 hours at a 25% load and a full tank. 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. As this inverter generator uses an estimated 0.2 GPH (gallon per hour) at a 25% load, it finds itself in the average gasoline consumption range of similar products. 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.

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
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.
This has been a great little generator. It has powered my grand design reflection with no problem and that includes the a/c.
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
I use my 4400 Predator exclusively for my car wash business. Runs my water pressure gun, air compressor my vac, and polisher with no problem at all. Only shut down for a gas refill. I love this generator for work purposes.
