Zoom on the Powerhorse 4000
In summary, the Powerhorse 4000 is a compact portable generator especially useful for:
- RV travellers who wish to upgrade their experience to another level
- Occasional participants of outdoor events, competitions, concerts and festivals
- Handcrafting enthusiasts who wish to work on-the-go
- 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, including its emission compliance information.
Power & Run Time
The Powerhorse 4000's design includes a gasoline-fueled 212 cc OHV 4-stroke engine. With a 120/240V output, it gives a running wattage of 3100W and also a peak wattage of 4000W.
The generator is rated for a noise of 95 dBA (which is pretty noisy). Its starting mechanism is based on a conventional pull-start mechanism.
Thanks to a fuel capacity of 3.9 gallons, the 4000 can operate for around 10.6 hours at 50% load with a full tank (fuel consumption around 0.37 GPH).
The 4000 generates a clean sine wave: providing <5% Total Harmonic Disruption (THD), delicate electronics can be plugged in its AC outlets safely.
The control panel features the following 9 AC outlets:
Furthermore, it has 1 DC outlet: there's a 12V 8A (cigarette lighter style) receptacle allowing you to easily charge your batteries.
Because the 4000 is equipped with a twist-lock L14-30R receptacle, it is transfer switch ready: it can power your home during a power outage, as it can be easily connected to your breaker box to power your household.
With its dimensions of L25.4 x W18.8 x H19.8 in, the conventional, open frame design of the Powerhorse 4000 offers stability and allows the generator to be raised above ground level. The generator is designed for ideal use outdoors and in rough environments.
Since the generator weighs 115 lbs, it will be incredibly difficult to manually lift it and transport it, even though it is technically considered to 'be portable' (in the sense that it is movable). 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 4000's status and activity may be monitored conveniently via the control panel, as it features a handy voltmeter that allows you to easily monitor power output anytime.
In addition to this info, a light indicator serves to show you when the oil level is too low.
The 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.
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, so it is adequate for use 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).
- Since the generator weighs in at a dry weight of 115 lbs, the Powerhorse 4000 belongs in the expected weight range for devices which can produce between 2500 and 3500 rated watts. In terms of weight, one of the champions in their power range is the WEN GN400i, standing at just 66.1 lbs.
- This generator, with its lowest possible noise rated at 95 dBA falls into the more noisy category, compared to other devise of a similar running wattage. 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.
- Offering around 10.6 hours of running time on a full tank at 50% load, the 4000 is within the average autonomy range of similarly powerful generators. Furthermore, considering the run times, one of the generators which have a roughly same power output, with the highest autonomy, is the Honda EB4000X, as it provides around 16 hours.
- The run time is important, but also hugely depends on the capacity of the fuel tank and doesn't mean much if we don't talk about fuel consumption as well. 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 you are concerned with gasoline efficiency, having a fuel consumption of just 0.17 GPH, the Westinghouse iGen4200 is a device you should look out for.
As you can see from this interactive chart, when compared to other 2500-3500W generators, the Powerhorse 4000 is on the cheap side of the price range.
It can therefore be a really good buy if you're looking to acquire a budget generator.
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
