Zoom on the Powerhorse 4000
In summary, the Powerhorse 4000 is a compact portable generator especially useful for:
- RV travellers looking for even more independence
- People occasionally participating in sporting competitions, open-air performances and outdoor festivals
- Amateur DIY lovers
- Homeowners who want to be sure of their ability to power their fridges, cooking tools, heating and lighting equipment during power failures
The following sections will present you in detail its power characteristics, the different outlets it offers, its overall portability, the extra features it benefits from, and any relevant emission compliance details.
Power & Run Time
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 3100W and a peak wattage of 4000W.
Enjoying a noise rating of 95 dBA (which is pretty noisy), this generator gets running thanks to a conventional pull-start mechanism.
The fuel capacity of 3.9 gallons allows the 4000 to operate for around 10.6 hours at 50% load with a full tank (fuel consumption around 0.37 GPH).
Sensitive electronics can be safely plugged in the AC outlets, as the 4000 produces a clean sine wave, with a <5% Total Harmonic Disruption (THD).
The control panel includes the following 9 AC outlets:
Furthermore, it has 1 DC outlet: there's a 12V 8A (cigarette lighter style) receptacle with which charging your batteries is made easy.
Due to the featured twist-lock L14-30R receptacle, the 4000 is transfer switch ready: you may connect it to a breaker box to power your household during a power outage.
The Powerhorse 4000 has the following dimensions: L25.4 x W18.8 x H19.8 in. In combination with its conventional, open frame design, they provide support and allow the generator to be raised above ground level. The device has been designed for tough environments and demanding outdoor use.
Although this generator is technically considered 'portable' (in the sense that it can be moved), its 115 lbs make it incredibly difficult to manually lift and transport. However, its challenging mobility is solved by its wheel kit and its folding handle, which will ease its displacement, once it is on the floor.
The control panel of the 4000 includes a handy voltmeter that allows you to easily monitor power output anytime, helpful for the monitoring of its status and activity.
In addition to this info, a light indicator serves to show you when 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.
From a security point of view, the generator is equipped with an overload protection (circuit breaker) and an automatic low oil shut-off, giving you a peace of mind during use.
As for its accessories, apart from the previously mentioned features, the Powerhorse 4000 also comes with the basic documentation and an owner's manual (opens in a new tab), allowing you to start it right away.
The Powerhorse 4000 is EPA approved, but NOT CARB-compliant. Thus, it cannot be purchased or sold in California.
However, it features a spark arrestor and thus, may be used in forested areas.
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).
- Having a dry weight of 115 lbs, the Powerhorse 4000 belongs in the expected weight range for generators which produce 2500 to 3500 rated watts. In terms of weight, one of the champions in their power range is the Genmax GM3300i, standing at just 47.4 lbs.
- When compared to devices able to produce a similar running wattage, this generator and its lowest emitted noise of 95 dBA is on the noisier side. If you’d prefer a less noisy device, one of the most quiet devices, which share the same power range with this one, is the Honda EU3000iS, whose lowest noise levels reach just 50 dBA.
- As the 4000 offers around 10.6 hours run time on a full tank at a 50% load, it falls within the average autonomy range among the generators of a similar power. Concerning the run times, one of the several devices with a comparable output, offering the highest autonomy, is the Predator 4375, which is able to run for around 16 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 generator is rather wasteful, compared to other devices within the aforementioned output range, when it comes to gasoline consumption, as it reaches roughly 0.37 GPH at a 50% load. If not satisfied with the afore-mentioned fuel consumption, you may wish to check out the Westinghouse iGen4200. With a fuel consumption of as little as 0.17 GPH, it is one of the most efficient generators currently on the market.
The bottom line
- Clean sine wave
- Decent weight (115 lbs)
- Decent run time
- No electric start
- Not CARB-compliant
- On the noisy side (95 dBA)
- Low fuel efficiency
