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
  • People occasionally participating in outdoor fairs, festivals or events
  • Homeowners in need of an emergency backup power for their essentials

In the forthcoming sections, you'll delve into its power characteristics, the various outlets it offers, its overall portability, and the additional features it boasts.

Power & Run Time

The Powerhorse 4500 in use

The Powerhorse 4500

The Powerhorse 4500's engine, 212 cc OHV 4-stroke, fueled by gasoline, can deliver 120V. It provides a running wattage of 3,600W and reaches a peak wattage of 4,500W.

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

With its 3.9 gallons fuel tank, the 4500 can operate for around 10.6 hours at 50% load when fully fueled (with fuel usage averaging around 0.37 GPH).

Featuring a <5% Total Harmonic Distortion (THD), the 4500 delivers a clean sine wave, guaranteeing the safety of your sensitive electronics plugged into its AC outlets.

Outlets

The control panel features 4 AC outlets as follows:

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 designed for hassle-free charging of various electronic devices such as smartphones and tablets, ensuring uninterrupted usage.

Featuring a TT-30R receptacle (TT for 'Travel Trailer'), this Powerhorse generator is RV Ready, designed specifically for use with recreational vehicles.

Portability

At L24.8 x W23 x H21.3 in, the Powerhorse 4500 boasts a traditional open frame structure, ensuring stability and allowing for convenient maintenance access to components, promoting air circulation. The device has been designed for tough environments and demanding outdoor use.

Despite its weight of 125 lbs, the generator is considered 'portable,' signifying its capability to be moved, albeit its heaviness may hinder easy transport. 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

The 4500's status and activity may be monitored conveniently via the control panel, as it features a convenient meter, displaying voltage, frequency, and lifetime hours information.

In addition to this info, a light indicator shows you if the oil level is too low.

Equipped with a built-in fuel gauge, the generator facilitates swift gas level checks.

Considering security aspects, the generator boasts an overload protection (circuit breaker) and an automatic low oil shut-off, offering peace of mind throughout operation.

Besides the classic documentation and an owner's manual (opens in a new tab) to get you promptly started, the Powerhorse 4500 also comes with some accessories: funnel and tool kit are included.

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).

  • With a dry weight of 125 pounds, the Powerhorse 4500 finds itself in the expected weight range for generators able to produce between 3500 and 4500 rated watts. In terms of weight, one of the champions in their power range is the Genmax GM4600iAEFIC, standing at just 58.4 lbs.
  • When comparing it to devices with a similar running wattage, this generator's lowest noise level of 70 dBA puts it alongside the noisier units. 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.
  • The 4500 provides around 10.6 hours of runtime at a 50% load on a full tank, placing it within the average autonomy range among similar generators. If run time is one of your main concerns, the Predator 4375 could be worth looking at. It boasts one of the highest run times among units of comparable power, lasting 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. When operating at 50% load, the generator's fuel consumption is estimated at 0.37 GPH, placing it within the average range of gasoline usage among similarly powerful devices. If you wish to further improve in the area of fuel efficiency, the Westinghouse iGen4500DF, which boasts with a gas consumption of only 0.23 GPH, may be the right generator for you.

Price comparison

As you can see from these interactive charts, 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.
