Description

Zoom on the Powerhorse 4500

In summary, the Powerhorse 4500 is a portable generator especially useful for:

  • RV travellers wishing to enhance their freedom and nomad lifestyle
  • Occasional participants of outdoor events, competitions, concerts and festivals
  • Homeowners who want to be able to use the most necessary devices in their household, even during a blackout

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 4500's core is the 212 cc OHV 4-stroke engine, which runs on gasoline. With an output of 120V, it provides a running wattage of 3600W and a peak wattage of 4500W.

This generator features a simple traditional pull-start mechanism.

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

Outlets

The control panel provides the upcoming 4 AC outlets:

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

Additionally, it features 2 DC outlets: there's two 5V USB ports allowing you to conveniently charge electronics such as mobile phones and tablets.

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

Portability

With its dimensions of L24.8 x W23 x H21.3 in, the conventional, open frame design of the Powerhorse 4500 offers stability and allows the generator to be raised above ground level. The generator is designed for ideal use outdoors and in rough environments.

As the generator's weight is 125 pounds, manually moving it or transporting it may be challenging, despite the fact that it is technically considered 'portable' (movable). However, this lack of maneuverability is compensated by its wheel kit and its folding handle, with which you can conveniently shift it, once it's on the ground.

Features

The 4500's control panel

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

In addition to this info, a light indicator shows you 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.

As far as security is concerned, the generator can be used with a peace of mind, as it features an automatic low oil shut-off and an overload protection (circuit breaker).

While the standard documentation and an owner's manual (opens in a new tab), helpful for starting the device promptly, come with the Powerhorse 4500, the following accessories are also included: funnel and tool kit.

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 and therefore, can be used 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).

  • As its weight is 125 pounds, the Powerhorse 4500 falls in the expected weight range of the devices in the 3500-4500 rated wattage category. Regarding dry weight, one of the champions in the same power range is the WEN GN400i, with a dry weight of only 66.1 lbs.
  • Regarding its autonomy, the autonomy of the 4500, reaching around 10.6 hours at a 50% load, can be considered as low end, compared to other products of a roughly equal output. If concerned with autonomy, one of the products of a comparable power output, which offers the highest run time, is the Honda EB4000X, boasting with 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 has an average fuel consumption among comparably powerful devices, as it reaches 0.37 GPH (gallon per hour) at a 50% load. If you wish to further improve in the area of fuel efficiency, the Westinghouse iGen4200, which boasts with a gas consumption of only 0.17 GPH, may be the right generator for you.

Price comparison

As you can see from this interactive chart, when compared to other 3500-4500W generators, the Powerhorse 4500 is on the average side of the price range.

Therefore, this generator nicely fits in the expected budget for this kind of product.
