Description

Zoom on the Powerhorse s4500d

In short, the Powerhorse s4500d is a portable generator adequately designed for:

  • RV travellers looking for even more independence
  • Occasional participants of outdoor events, competitions, concerts and festivals
  • Homeowners who want to be sure of their ability to power their fridges, cooking tools, heating and lighting equipment during power failures

The subsequent sections will explore in detail its power characteristics, the diverse outlets it provides, its overall portability, and the supplementary features it offers.

Power & Run Time

Thanks to its dual-fuel technology, the Powerhorse s4500d provides a 120V output and offers both versatility and power. When utilizing gasoline, it delivers a running wattage of 3,600W and a starting wattage of 4,500W. Alternatively, when operating on propane, it provides 3,200 running watts and 4,000 starting watts.

Enjoying a noise rating of 95 dBA (which is pretty noisy), this generator can be started thanks to a simple traditional pull-start mechanism, but also to a user-friendly and efficient electric starter (battery not included).

The s4500d, with a fuel capacity of 3.9 gallons, reaches a run time of around 10.6 hours at 50% load utilizing gasoline (fuel consumption around 0.37 GPH). Alternatively, it can reach a run time of around 11 hours (on a 20 lbs tank - propane consumption around 0.43 GPH) with propane.

Due to the high THD (<23%) of the s4500d, it is advised against using it for powering sensitive electronic devices.

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

Furthermore, it showcases 2 DC outlets: there's two 5V USB ports (USB-A) allowing you to conveniently charge electronics such as mobile phones and tablets.

Thanks to its TT-30R receptacle (TT meaning 'Travel Trailer'), this Powerhorse generator is RV Ready, ready to power your recreational vehicle with ease.

Portability

At L26.5 x W23.5 x H21.4 in, the traditional open frame structure of the Powerhorse s4500d ensures stability while facilitating convenient maintenance access to components and promoting air cooling. The device has been designed for tough environments and demanding outdoor use.

Although this generator is technically considered 'portable' (in the sense that it can be moved), its 121 lbs make may make it challenging to manually lift and transport. However, the limited maneuverability is remedied with its wheel kit and its folding handle, facilitating convenient shifting once the generator is positioned on the ground.

Features

The s4500d's control panel

For convenient monitoring of its status and activity, the control panel of the s4500d includes a convenient meter, providing voltage, frequency, and lifetime hours data.

In addition to this info, the generator's light indicator provides visual feedback when its oil levels are insufficient.

The built-in fuel gauge of the generator ensures simple and quick gas level assessments.

In terms of security, the generator features an automatic low oil shut-off and an overload protection (circuit breaker), ensuring peace of mind during its use.

It also includes a carbon monoxide sensor. This sensor is designed to monitor the level of carbon monoxide present during the generator's operation. If the generator is positioned incorrectly and carbon monoxide levels rise to an unsafe level, the generator will automatically shut down.

Besides the classic documentation and an owner's manual (opens in a new tab) to get you promptly started, the Powerhorse s4500d also comes with some accessories: funnel, propane hose and tool kit are included.

The Powerhorse s4500d versus other generators

The following charts are provided to give you an idea of how some of the key specs of the Powerhorse s4500d compare to dual fuel generators of similar power (between 3500 and 4500 W).

  • With its weight of 121 lbs, the Powerhorse s4500d is one of the heavier dual fuel generators in the 3500-4500 rated wattage category. If weight matters to you, one of the champions in this power range is the Pulsar PGX5250BiXCO with only 64 pounds.
  • In comparison to generators with a similar running wattage, this generator's lowest emitted noise of 95 dBA can be considered noisy. If you’d prefer a less noisy device, one of the most quiet devices, which share the same power range with this one, is the Westinghouse iGen5000DF, whose lowest noise levels reach just 52 dBA.
  • With around 10.6 hours of runtime at a 50% load on a full tank, the s4500d is in line with the average autonomy range for dual fuel generators of comparable power. If you wish to prioritize autonomy, the Westinghouse iGen5000DF shines as one of the top contenders, offering one of the highest run times among generators with similar power output, totaling around 15 hours.
  • Autonomy holds its importance, however, it is largely dependent on the generator’s fuel capacity and so, it is nonsensible to discuss it without mentioning fuel efficiency as well. 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 minimizing fuel usage is one of your key priorities, the Westinghouse iGen5000DF is one of the most efficient devices with similar power output, with a gasoline consumption of only 0.23 gallons per hour.

Price comparison

As you can see from these interactive charts, when compared to other 3500-4500W dual fuel generators, the Powerhorse s4500d is on the average side of the price range.

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