Description

Zoom on the Powerhorse 4500

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

  • RV travellers wishing to enhance their freedom and nomad lifestyle
  • People occasionally participating in outdoor fairs, festivals or events
  • Homeowners who want to be able to use the most necessary devices in their household, even during a blackout

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's engine, 212 cc OHV 4-stroke, fueled by gasoline, can deliver 120V. It provides a running wattage of 3600W and reaches a peak wattage of 4500W.

This generator is started via a conventional 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).

Outlets

The control panel features the following 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.

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

Portability

The Powerhorse 4500 has a conventional, open frame design, of the following dimensions: L24.8 x W23 x H21.3 in, which offers support and allows it to be raised above ground level. The generator is designed for ideal use outdoors and in rough environments.

Even though this device may be technically portable (as in movable), manipulation and transportation without special equipment can be a challenge, as it weighs 125 pounds. Still, once it is on the ground, its wheel kit and its folding handle can easily solve the issue of low mobility and allow for easy relocation of the device.

Features

Panel of the Powerhorse 4500

The 4500's control panel

The 4500's control center features a convenient meter, which displays voltage, frequency and lifetime hours to aid you with the monitoring of its status and activity.

In addition to this info, a light indicator serves to show you when the oil level is too low.

A built-in fuel gauge allows for a quick, easy and convenient check of the fuel level of the generator.

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.

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, making it usable 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).

  • At a weight of 125 pounds, the Powerhorse 4500 places in the expected weight range of the generators in the 3500-4500 rated wattage range. If weight is your top priority, one of the champions in this power category is the WEN GN400i, weighing just 66.1 pounds.
  • The 4500's autonomy is somewhat low end compared to devices of its power range, as it reaches only around 10.6 hours at 50% load on a full tank. 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.
  • While the run time is an important parameter, it is dependent on the fuel tank’s capacity and thus, doesn’t say much on its own unless we consider fuel consumption as well. As this generator uses an estimated 0.37 GPH (gallon per hour) at a 50% load, it finds itself in the average gasoline consumption range of similar products. 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.

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.
