Description

The PM4500E features a steel frame and a compact design with integrated wheels and handle that makes it easy to move and put in place. With 4500 starting watts and 3600 running watts, this generator is powerful enough to run small electrical appliances at any picnic, campground or tailgate and versatile enough to power tools for your next DIY project.

Zoom on the Powermate PM4500E

In summary, the Powermate PM4500E is a portable generator especially useful for:

  • RV travellers who wish to upgrade their experience to another level
  • People occasionally participating in outdoor fairs, festivals or events
  • 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 be able to deliver results, even during a power failure

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 Powermate PM4500E's core is the 224 cc Generac OHV 4-stroke engine, which runs on gasoline. With an output of 120V, it provides a running wattage of 3600W and a peak wattage of 4500W.

This generator features a simple traditional pull-start mechanism, but also a convenient and easy-to-use electric starter (battery included).

With a full tank, the PM4500E can operate for up to 20 hours (fuel consumption around 0.25 GPH), thanks to its fuel capacity of 5 gallons.

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 design of the Powermate PM4500E is a typical, open frame, with the dimensions of L26.3 x W22.9 x H21.6 in, offering support and stability and enabling the possibility of raising it above ground level. This type of design is ideal for tough environments and heavy outdoor use.

Even though this device may be technically portable (as in movable), manipulation and transportation without special equipment can be a challenge, as it weighs 114 pounds. However, this lack of maneuverability is compensated by its wheel kit (⌀8") and its folding handle, with which you can conveniently shift it, once it's on the ground.

Features

Panel of the Powermate PM4500E

The PM4500E's control panel

Monitoring of the PM4500E's status and activity is made possible by a digital data center, which provides information on the lifetime run hours and is one of the features of its control panel.

Thanks to a built-in fuel gauge, the generator allows you to quickly, conveniently and easily check the gas level at a glance.

From a security point of view, the generator is equipped with an automatic low oil shut-off and an overload protection (circuit breaker), giving you a peace of mind during use.

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 PM4500E's packaging.

Emissions

The Powermate PM4500E is EPA approved, but NOT CARB-compliant. Thus, it cannot be purchased or sold in California.

However, it features a spark arrestor, so it is adequate for use in forested areas.

Product Video

The Powermate PM4500E versus other generators

The following charts are provided to give you an idea of how some of the key specs of the Powermate PM4500E compare to generators of similar power (between 3500 and 4500 W).

  • With a dry weight of 114 pounds, the Powermate PM4500E 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 WEN GN400i, standing at just 66.1 lbs.
  • As the PM4500E features an autonomy of up to 20 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.
  • 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. In fact, this generator is not among the most fuel efficient, within the aforementioned wattage range : its estimated gasoline consumption at 25% load is around 0.25 GPH. 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 0.14 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 Powermate PM4500E 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.

The bottom line
