Description

Zoom on the Powermate PM4500DF

In summary, the Powermate PM4500DF is a portable generator especially useful for:

  • RV travellers looking for even more independence
  • People occasionally participating in sporting competitions, open-air performances and outdoor festivals
  • Homeowners in need of an emergency backup power for their essentials
  • Professionals who want to ensure that a power failure will not prevent them from working

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

Thanks to its dual-fuel technology, the Powermate PM4500DF delivers 120/240V and offers power and versatility. When gasoline-powered, it benefits from a running wattage of 3600W and a peak wattage of 4500W. When propane-powered, it has 3240 rated watts and 4180 peak watts.

The generator features a conventional pull-start mechanism.

The PM4500DF, with a fuel capacity of 5 gallons, reaches a run time of around 10.5 hours at 50% load utilizing gasoline (fuel consumption around 0.48 GPH). Alternatively, it can reach a run time of around 7 hours (estimation based on a 20 lbs tank - propane consumption around 0.67 GPH) with propane.

Outlets

The control panel provides the upcoming 3 AC outlets:

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

This Powermate generator features an L5-30R receptacle, enabling an easy RV connection via an L5-30P to TT-30R adaptor. However, it is still not quite RV ready.

Portability

The Powermate PM4500DF has the following dimensions: L26.3 x W22.9 x H21.5 in. In combination with its conventional, open frame design, they provide support and allow the generator to be raised above ground level. The featured design is ideal for the outdoors and all tough environments.

Although this generator is technically considered 'portable' (in the sense that it can be moved), its 109 lbs make it incredibly difficult to manually lift and transport. 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

The PM4500DF's control panel

A digital data center, one of the features of the PM4500DF's control panel, gives you information on the lifetime run hours, and thus, is helpful for the monitoring of its activity and status.

A built-in fuel gauge allows for a quick, easy and convenient check of the fuel level of the generator.

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.

Along the basic documentation and an owner's manual, useful for starting the generator right away, the Powermate PM4500DF's package also includes these accessories: propane hose and oil.

Emissions

The Powermate PM4500DF 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.

The Powermate PM4500DF versus other generators

The following charts are provided to give you an idea of how some of the key specs of the Powermate PM4500DF compare to generators of similar power (between 3500 and 4500 W).

  • At a weight of 109 pounds, the Powermate PM4500DF places in the expected weight range of the generators in the 3500-4500 rated wattage range. If weight is your top priority, one of the champions in this power category is the WEN GN400i, weighing just 66.1 pounds.
  • Regarding its autonomy, the autonomy of the PM4500DF, reaching around 10.5 hours at a 50% load, can be considered as low end, compared to other products of a roughly equal output. Concerning the run times, one of the several devices with a comparable output, offering the highest autonomy, is the Predator 4375, which is able to run for around 16 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 somewhat less fuel efficient than devices of comparable output: its estimated fuel consumption reaches 0.48 GPH at a 50% load. If you wish to acquire one of the most gasoline efficient products of this power range, the Westinghouse iGen4200, with a fuel consumption of 0.17 GPH could be in your good books.

Price comparison

As you can see from this interactive chart, when compared to other 3500-4500W generators, the Powermate PM4500DF is on the average side of the price range.

Therefore, this generator nicely fits in the expected budget for this kind of product.

Unlike many websites, we did our best to research each of the specs above. That being said, we are not immune to making the occasional mistake or omission. Should you notice any missing or incorrect values, don't hesitate to suggest improvements so we can address the issue.
* Propane runtime is our own estimation, based on a 20 lbs tank and NIST 1994 GGE (Gasoline Gallon Equivalent) formula: 5.66 lbs of propane = 1 gal of gasoline.
