Description

Zoom on the Powerhorse 4500

In a nutshell, the Powerhorse 4500 is a portable generator mostly geared towards:

  • RV travellers looking for even more independence
  • People occasionally participating in sporting competitions, open-air performances and outdoor festivals
  • Homeowners in need of an emergency backup power for their essentials

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 4500 in use

The Powerhorse 4500

The Powerhorse 4500 houses a 212 cc OHV 4-stroke engine, which provides 120V, consumes gasoline and delivers a running wattage of 3,600W along with a peak wattage of 4,500W.

The generator is rated for a noise of 70 dBA (just as noisy as a vacuum cleaner). Its starting mechanism is based on a simple traditional pull-start mechanism.

Thanks to a fuel capacity of 3.9 gallons, the 4500 can operate for around 10.6 hours at 50% load with a full tank (fuel consumption around 0.37 GPH).

The 4500 produces a clean sine wave: thanks to a <5% Total Harmonic Distortion (THD), your sensitive electronics can be safely plugged in the AC outlets.

Outlets

The control panel features the upcoming 4 AC outlets:

Duplex 120V 20A (5-20R)
120V 30A (L5-30R) receptacle
120V 30A (TT-30R) receptacle

Furthermore, it has 2 DC outlets: there's two 5V USB ports with which you may charge electronics, for example mobile phones or tablets, conveniently.

Thanks to its TT-30R receptacle (TT stands for 'Travel Trailer'), this Powerhorse generator is RV Ready.

Portability

The design of the Powerhorse 4500 is a typical, open frame, with the dimensions of L24.8 x W23 x H21.3 in, offering support and stability and enabling the possibility of raising it above ground level. The design is ideal for rough 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 125 lbs. Nevertheless, it can still be moved quite conveniently with the help of its wheel kit and its folding handle, once it is placed on the ground.

Features

Panel of the Powerhorse 4500

The 4500's control panel

To help you monitor the 4500's status and activity, its control panel is equipped with a convenient meter, which displays voltage, frequency and lifetime hours.

In addition to this info, the device’s light indicator will display if the oil level is too low.

The fuel level of the generator can be determined quickly, easily, and conveniently with the help of its built-in fuel gauge.

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.

Along the basic documentation and an owner's manual (opens in a new tab), useful for starting the generator right away, the Powerhorse 4500's package also includes these accessories: tool kit and funnel.

Emissions

The Powerhorse 4500 is EPA approved, but NOT CARB-compliant. Thus, it cannot be purchased or sold in California.

However, it features a spark arrestor, which makes it suitable for use in forested areas.

The Powerhorse 4500 versus other generators

The following charts are provided to give you an idea of how some of the key specs of the Powerhorse 4500 compare to generators of similar power (between 3500 and 4500 W).

  • Having a dry weight of 125 lbs, the Powerhorse 4500 belongs in the expected weight range for generators which produce 3500 to 4500 rated watts. If weight is your top priority, one of the champions in this power category is the Genmax GM4600iAEFIC, weighing just 58.4 pounds.
  • As this generator has its lowest possible noise of 70 dBA, it should be considered noisier compared to its peers of a comparable running wattage. If you are concerned with noise, check out the Westinghouse iGen4500DF, which is one of the least noisy generators in its power range, with a noise rating of just 52 dBA.
  • Offering around 10.6 hours of running time on a full tank at 50% load, the 4500 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 Predator 4375, as it provides 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. Standing at an estimated 0.37 GPH (gallon per hour) at a 50% load, this generator is somewhat average in this area compared to other devices, within the aforementioned wattage range. If you wish to acquire one of the most gasoline efficient products of this power range, the Westinghouse iGen4500DF, with a fuel consumption of 0.23 GPH could be in your good books.

Price comparison

As you can see from these interactive charts, when compared to other 3500-4500W generators, the Powerhorse 4500 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.
