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 short, the Powermate PM4500E is a portable generator adequately designed for:

  • RV travellers looking for even more independence
  • Occasional participants of outdoor events, competitions, concerts and festivals
  • Homeowners in need of an emergency backup power for their essentials
  • 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, and the extra features it benefits from.

Power & Run Time

Running on gasoline, the Powermate PM4500E utilizes a 224 cc Generac OHV 4-stroke engine to deliver 120V, offering a running wattage of 3,600W and a starting wattage of 4,500W.

Equipped with a traditional recoil pull-start mechanism and an intuitive and practical electric starter (battery included), this generator provides versatile starting capabilities.

Featuring a 5 gallons fuel tank, the PM4500E can provide power for up to 20 hours on a full tank (with fuel consumption averaging 0.25 gallons per hour).

Outlets

The control panel features 5 AC outlets as follows:

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

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

Portability

With dimensions of L26.3 x W22.9 x H21.6 in, the standard open frame design of the Powermate PM4500E provides stability and easy maintenance access to components, as well as good air circulation. The design is ideal for rough environments and demanding outdoor use.

With a weight of 114 lbs, the generator is still labeled as 'portable,' denoting its ability to be moved, although its heaviness might restrict easy portability. However, the constrained maneuverability is addressed with the assistance of its wheel kit (⌀8") and its folding handle, allowing for easy shifting once the generator is placed on the ground.

Features

Panel of the Powermate PM4500E

The PM4500E's control panel

The PM4500E's control panel is equipped with a digital data center, furnishing detailed information on the lifetime run hours for you to easily track its activity and status.

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

As far as security is concerned, the generator can be used with a peace of mind, as it features an overload protection (circuit breaker) and an automatic low oil shut-off.

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.

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 lbs, the Powermate PM4500E falls within the expected weight range for generators in the 3500 to 4500 rated wattage. Regarding dry weight, one of the champions in the same power range is the Genmax GM4600iAEFIC, with a dry weight of only 58.4 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 extended autonomy is what matters most to you, the Firman W03661OF could be an excellent choice, offering one of the longest run times among units in its power category, reaching up to 25 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 you wish to further improve in the area of fuel efficiency, the Champion 200988, which boasts with a gas consumption of only 0.16 GPH, may be the right generator for you.

Price comparison

As you can see from these interactive charts, 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.
