Description
Zoom on the Powerhorse 4000
In a few words, the Powerhorse 4000 is a compact portable generator perfectly suited for:
- RV travellers who wish to upgrade their experience to another level
- 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
In the sections ahead, the power characteristics, availability of various outlets, the portability, and any additional features of the device shall be discussed.
Power & Run Time
The Powerhorse 4000
The Powerhorse 4000's core is the 212 cc OHV 4-stroke engine, which runs on gasoline. With an output of 120/240V, it provides a running wattage of 3,100W and a peak wattage of 4,000W.
Operating at a noise rating of 95 dBA (which is pretty noisy), this generator starts up with a conventional pull-start mechanism.
The 4000's fuel tank holds 3.9 gallons, ensuring uninterrupted operation for around 10.6 hours at 50% load with a full tank (fuel consumption approximately 0.37 GPH).
The <5% Total Harmonic Distortion (THD) of the 4000 ensures a clean sine wave output, providing a secure power source for your sensitive electronics through its AC outlets.
Outlets
The control panel features the upcoming 9 AC outlets:
Additionally, it offers 1 DC outlet: there's a 12V 8A (cigarette lighter style) receptacle offering a convenient battery charging option.
Since it boasts a twist-lock L14-30R receptacle, the 4000 is engineered to be transfer switch ready, ensuring easy integration with your breaker box to provide backup power to your home during outages.
Portability
Measuring L25.4 x W18.8 x H19.8 in, the Powerhorse 4000 showcases a classic open frame layout, guaranteeing stability and simple maintenance access to components, while facilitating air circulation. The design is ideal for rough environments and demanding outdoor use.
Despite its 115 lbs, the generator falls under the category of 'portable,' signifying its movability, although its weight may hinder easy portability. Nonetheless, the limited maneuverability is compensated for by utilizing its wheel kit and its folding handle, which facilitates shifting once the generator is set on the ground.
Features
The 4000's control panel
Integrated into the control center of the 4000 are a handy voltmeter that allows you to easily monitor power output anytime, facilitating the monitoring of its status and activity.
In addition to this info, a light indicator shows you if its oil levels are insufficient.
A built-in fuel gauge allows for a quick, easy and convenient check of the fuel level of the generator.
Considering security aspects, the generator boasts an automatic low oil shut-off and an overload protection (circuit breaker), offering peace of mind throughout operation.
Accessory-wise, along with the previously mentioned features, the Powerhorse 4000 is packaged with the standard documentation and an owner's manual (opens in a new tab), helping you start the device right away.

The Powerhorse 4000 versus other generators
The following charts are provided to give you an idea of how some of the key specs of the Powerhorse 4000 compare to generators of similar power (between 2500 and 3500 W).
- With a weight of 115 lbs, the Powerhorse 4000 sits in the heavier end of the spectrum among generators rated from 2500 to 3500 watts. In terms of weight, one of the champions in their power range is the Pulsar PGD40iSCO, standing at just 46 lbs.
- When compared to other units producing a similar running wattage, this generator and its lowest emitted noise of 95 dBA stand out for being on the louder side. If noise level is one your key decisive factors, you may find the Honda EU3000iS appealing. It's rated at 50 dBA, making it one of the quietest generators in its power range.
- Given that the 4000 reaches an autonomy of around 10.6 hours with a full tank and at 50% load, it is placed within the average autonomy range of similarly powerful generators. For those prioritizing autonomy, the Predator 4375 could be considered, as it offers one of the longest run times among generators with similar power output, reaching around 16 hours.
- Run time is crucial, but it heavily relies on the fuel tank's capacity. Thus, considering fuel efficiency alongside is essential. This generator is somewhat less fuel-efficient than devices of comparable output: its estimated fuel consumption reaches 0.37 GPH at a 50% load. If not satisfied with the afore-mentioned fuel consumption, you may wish to check out the Pulsar PGD40iSCO. With a fuel consumption of as little as 0.22 GPH, it is one of the most efficient generators currently on the market.
The bottom line
- Impressive quantity of AC outlets
- Clean sine wave
- Decent run time
- No electric start
- On the heavy side (115 lbs)
- On the noisy side (95 dBA)
- Low fuel efficiency

User Reviews
I have one of these and never had any problem! Which is a good thing. But if it was 2-4 degrees I’m not to sure I would care unless ALL POWER WAS OUT EVERYWHERE!!
Swap out the 13.6 breakers for 20 amp breakers and it run anything.
During a recent arctic blast the temperatures dropped to 2°- 4° F. Grid power went out. I could not get my 4000 to start. I even brought it indoors (50°F and falling) to warm it up…53 hours later, the power came back. The generator was useless. It had a total of 4.5 hours run time and meticulously maintained.
