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 in need of an emergency backup power for their essentials
  • Professionals in need of safely powering high-intensity work or lighting equipment

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 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 can be started via a simple traditional pull-start mechanism, or a simple and elegant electric starter (battery included).

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

Outlets

The control panel includes the following 5 AC outlets:

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

While this Powermate generator is not RV Ready, its L5-30R receptacle can be used for a simple RV connection with an L5-30P to TT-30R adaptor.

Portability

The dimensions of the Powermate PM4500E, which are L26.3 x W22.9 x H21.6 in, and its typical, open frame design provides stability and enables the generator to be raised above ground level. This type of design is ideal for tough environments and heavy outdoor use.

Although this generator is technically considered 'portable' (in the sense that it can be moved), its 114 lbs make it incredibly difficult to manually lift and transport. 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 PM4500E

The PM4500E's control panel

The control panel of the PM4500E includes a digital data center, which assists you in monitoring its status and activity, as it provides 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.

From a security standpoint, the product offers an automatic low oil shut-off and an overload protection (circuit breaker), allowing you to use it with a peace of mind.

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, which makes it suitable 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).

  • Having a dry weight of 114 lbs, the Powermate PM4500E belongs in the expected weight range for generators which produce 3500 to 4500 rated watts. 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.
  • With a run time of up to 20 hours at 25% load, the PM4500E has one of the higher run times, compared to its similarly powerful peers. 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. This generator is not fuel efficient compared to devices of similar output: its estimated fuel consumption stands at 0.25 GPH at a 25% load. If fuel consumption is your top priority, we suggest to check out the Westinghouse iGen4200, which has a fuel consumption of only 0.14 GPH and thus, is one of the most efficient devices in our database.

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.
