Zoom on the Powermate PM4500

In a nutshell, the Powermate PM4500 is a portable generator mostly geared towards:

  • RV travellers who wish to upgrade their experience to another level
  • People occasionally participating in sporting competitions, open-air performances and outdoor festivals
  • Homeowners who want to be sure of their ability to power their fridges, cooking tools, heating and lighting equipment during power failures
  • Professionals who want to ensure that a power failure will not prevent them from working

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 Powermate PM4500 in use

The Powermate PM4500

The Powermate PM4500's design includes a gasoline-fueled 224 cc Generac OHV 4-stroke engine. With a 120V output, it gives a running wattage of 3600W and also a peak wattage of 4500W.

This generator gets running thanks to a simple traditional pull-start mechanism. It features Powermate's PowerDial™, an easy-to-use dial with three operation settings.

The fuel capacity of 5 gallons allows the PM4500 to operate for up to 19 hours with a full tank (fuel consumption around 0.26 GPH).

Outlets

The control panel provides the upcoming 5 AC outlets:

Two Duplexes 120V 20A (5-20R) GFCI
120V 30A (L5-30R) receptacle

Even if this Powermate generator isn't quite RV Ready, it still allows for an easy RV connection via an L5-30P to TT-30R adaptor, thanks to its L5-30R receptacle.

Portability

The dimensions of the Powermate PM4500, which are L26.3 x W22.9 x H21.5 in, and its typical, open frame design provides stability and enables the generator to be raised above ground level. The device has been designed for tough environments and demanding outdoor use.

As the generator's weight is 105 pounds, manually moving it or transporting it may be challenging, despite the fact that it is technically considered 'portable' (movable). Nevertheless, thanks to its wheel kit (⌀8") and its folding handle (a decent solution to its lack of maneuverability), the generator can be easily moved, once placed the ground.

Features

Panel of the Powermate PM4500

The PM4500's control panel

To help you monitor the PM4500's status and activity, its control panel is equipped with a digital data center, giving you information on the lifetime run hours.

The generator includes a built-in fuel gauge, a quick, easy and convenient method of checking the device’s gas level.

Security-wise, this product benefits from an overload protection (circuit breaker) and an automatic low oil shut-off, which gives you a complete peace of mind when using it.

Besides the usual set of documentation and owner's manual (opens in a new tab) to get you promptly started, Powermate also included some oil in the PM4500's packaging.

Emissions

The Powermate PM4500 is EPA-approved and CARB-compliant. It can therefore be sold and purchased in all 50 states, including California.

Moreover, it features a spark arrestor, making it usable in forested areas.

Product Video

The Powermate PM4500 versus other generators

The following charts are provided to give you an idea of how some of the key specs of the Powermate PM4500 compare to generators of similar power (between 3500 and 4500 W).

  • At a weight of 105 pounds, the Powermate PM4500 places in the expected weight range of the generators in the 3500-4500 rated wattage range. If weight matters to you, one of the champions in this power range is the WEN GN400i with only 66.1 pounds.
  • As the PM4500 features an autonomy of up to 19 hours at 25% load, it has a higher run time than an average generator of its power range. If concerned with autonomy, one of the products of a comparable power output, which offers the highest run time, is the Champion 200954, boasting with up to 22 hours.
  • The run time is important, but also hugely depends on the capacity of the fuel tank and doesn't mean much if we don't talk about fuel consumption as well. This generator is not fuel efficient compared to devices of similar output: its estimated fuel consumption stands at 0.26 GPH at a 25% load. If you are concerned with gasoline efficiency, having a fuel consumption of just 0.14 GPH, the Westinghouse iGen4200 is a device you should look out for.

Price comparison

As you can see from this interactive chart, when compared to other 3500-4500W generators, the Powermate PM4500 is on the cheap side of the price range.

It can therefore be a really good buy if you're looking to acquire a budget generator.
