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
  • Occasional participants of outdoor events, competitions, concerts and festivals
  • Homeowners who want to be able to use the most necessary devices in their household, even during a blackout
  • Professionals who want to be able to deliver results, even during a power failure

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'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 thanks to a conventional pull-start mechanism, but also to 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 includes the following 5 AC outlets:

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

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.

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, it can still be moved quite conveniently with the help of its wheel kit (⌀8") and its folding handle, once it is placed on 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.

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

Security-wise, this product benefits from an automatic low oil shut-off and an overload protection (circuit breaker), 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 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 and therefore, can be used in forested areas.

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).

  • As its weight is 114 pounds, the Powermate PM4500E falls in the expected weight range of the devices in the 3500-4500 rated wattage category. If weight is your top priority, one of the champions in this power category is the WEN GN400i, weighing just 66.1 pounds.
  • Thanks to an impressive running time of up to 20 hours at 25% load, the PM4500E benefits from a higher run time than many generators of a similar output. If autonomy is your priority, one of the devices of a similar power output with the highest run time is the Champion 200954, reaching 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. Compared to its peers, this generator is not exactly fuel efficient, compared to similarly powerful devices, with an estimated fuel consumption of 0.25 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 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.

About Powermate

Powermate’s history is somewhat enigmatic, but they claim to have been on the market for over 40 years, selling portable generators and various outdoor power equipment. What we know for sure is that in 2009, they have signed under what they call “partnership” (more accurately ownership) with the Italian PRAMAC. As of 2020, it would seem that Generac has now taken over the manufacturing of Powermate's portable generators.

Warranty Information

The Powermate PM4500E is covered under a warranty for up to 3 years. This warranty may be limited and may not cover all parts of the generator.
For more information about the warranty of Powermate generators, please consult Powermate's warranty policies (opens in a new tab). Alternatively, you can also contact their Customer Support: 1-800-445-1805.
