Zoom on the Powerhorse 4000
In a nutshell, the Powerhorse 4000 is a compact portable generator mostly geared towards:
- RV travellers looking for even more independence
- Occasional participants of outdoor events, competitions, concerts and festivals
- DIYers who wish to improve their efficiency with tools
- Homeowners in need of an emergency backup power for their essentials
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 is powered by a 212 cc OHV 4-stroke engine. It delivers 120/240V, runs on gasoline and offers a running wattage of 3100W as well as a peak wattage of 4000W.
With a noise rating of 95 dBA (which is pretty noisy), the generator features a simple traditional pull-start mechanism.
The 4000 can operate for around 10.6 hours at 50% load with a full tank (fuel consumption around 0.37 GPH), due to its fuel capacity of 3.9 gallons.
As the 4000 produces a clean sine wave, with a <5% Total Harmonic Disruption (THD), sensitive electronics may be plugged in the AC outlets safely.
The control panel provides the upcoming 9 AC outlets:
Additionally, it features 1 DC outlet: there's a 12V 8A (cigarette lighter style) receptacle with which you may charge your batteries with ease.
As the 4000 holds a twist-lock L14-30R receptacle, it is transfer switch ready: you'll easily be able to connect it to your breaker box to power your home during a power outage.
The Powerhorse 4000 has a conventional, open frame design, of the following dimensions: L25.4 x W18.8 x H19.8 in, which offers support and allows it to be raised above ground level. The device has been designed for tough environments and demanding outdoor use.
While the generator is considered to be technically 'portable' (in the sense that you can move it), manually lifting and transporting it may be challenging, due to its high weight of 115 lbs. 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 shows you if the oil level is too low.
The generator includes a built-in fuel gauge, a quick, easy and convenient method of checking the device’s gas level.
Security-wise, this product benefits from an automatic low oil shut-off and an overload protection (circuit breaker), which gives you a complete peace of mind when using it.
Along with the aforementioned features, from an accessory standpoint, the Powerhorse 4000's box includes the typical documentation and an owner's manual (opens in a new tab), which will help you start your generator promptly.
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, making it usable 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).
- At a dry weight of 115 pounds, the Powerhorse 4000 is one of the heavier devices which can produce between 2500 and 3500 running watts. If weight matters to you, one of the champions in this power range is the Generac GP3300i with only 59.5 pounds.
- 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.
- The 4000, offering a run time of around 10.6 hours with a full tank at a 50% load, falls within the average autonomy range when compared to its peers. If autonomy is your priority, one of the devices of a similar power output with the highest run time is the Predator 4375, reaching 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 has an estimated fuel consumption of roughly 0.37 GPH (gallon per hour) at a 50% load, rendering it somewhat average compared to devices of a similar output. 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 average side of the price range.
Therefore, this generator nicely fits in the expected budget for this kind of product.
The bottom line
- In the expected price range
- Clean sine wave
- Decent run time
- Decent fuel efficiency
- No electric start
- Not CARB-compliant
- On the heavy side (115 lbs)
- On the noisy side (95 dBA)
