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 looking for even more independence
  • 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 in need of safely powering high-intensity work or lighting equipment

The following sections will present you in detail its power characteristics, the different outlets it offers, its overall portability, the extra features it benefits from, and any relevant emission compliance details.

Power & Run Time

The Powermate PM4500E is powered by a 224 cc Generac OHV 4-stroke engine. It delivers 120V, runs on gasoline and offers a running wattage of 3600W as well as a peak wattage of 4500W.

Its starting mechanisms include a conventional pull-start mechanism and 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 features the upcoming 5 AC outlets:

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

This Powermate generator isn't quite RV Ready, but it features an L5-30R receptacle, allowing a simple RV connection through an L5-30P to TT-30R adaptor.

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. The design is ideal for rough environments and demanding outdoor use.

As the generator's weight is 114 pounds, manually moving it or transporting it may be challenging, despite the fact that it is technically considered 'portable' (movable). However, its challenging mobility is solved by its wheel kit (⌀8") and its folding handle, which will ease its displacement, once it is on the floor.

Features

Panel of the Powermate PM4500E

The PM4500E's control panel

To help you monitor the PM4500E's status and activity, its control panel is equipped with a digital data center, giving you information on the lifetime run hours.

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

As for its security measures, the device features an automatic low oil shut-off and an overload protection (circuit breaker), letting you 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).

  • 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.
