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 who want to be able to use the most necessary devices in their household, even during a blackout

In the following paragraphs, we shall explore the power characteristics, available outlets, portability, and any additional features of the device, along with its emission compliance information.

Power & Run Time

The Powerhorse 4500 in use

The Powerhorse 4500

The Powerhorse 4500 is powered by a 212 cc OHV 4-stroke engine. It delivers 120V, runs on gasoline and offers a running wattage of 3600W as well as a peak wattage of 4500W.

This generator is started via 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 features the following 4 AC outlets:

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

It also sports 2 DC outlets: there's two 5V USB ports with which charging of electronics like mobile phones and tablets is made convenient.

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

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 featured design is ideal for the outdoors and all tough environments.

Since the generator weighs 125 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). 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 status and activity may be monitored conveniently via the control panel, as it features a convenient meter showing you voltage, frequency and lifetime hours.

In addition to this info, a light indicator serves to show you when its oil levels are insufficient.

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

As for its security measures, the device features an overload protection (circuit breaker) and an automatic low oil shut-off, 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: 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, 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).

  • 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. If you are concerned by weight, one of the champions in the above-mentioned power range is the WEN GN400i, with a dry weight of just 66.1 pounds.
  • 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 you consider autonomy on a single full tank as one of the deciding factors, one of the generators in the same power range that offers the highest run time is the Predator 4375, with 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. 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 could look out for.

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.
