Zoom on the Powermate PM4500
In summary, the Powermate PM4500 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
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 PM4500's engine, 224 cc Generac OHV 4-stroke, fueled by gasoline, can deliver 120V. It provides a running wattage of 3,600W and reaches a peak wattage of 4,500W.
Its starting mechanism is based on a simple traditional pull-start mechanism. It features Powermate's PowerDial™, an easy-to-use dial with three operation settings.
With a fuel capacity of 5 gallons, the PM4500 may run for up to 19 hours with a full tank (fuel consumption around 0.26 GPH).
The control panel features the following 5 AC outlets:
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.
The Powermate PM4500 has a conventional, open frame design, of the following dimensions: L26.3 x W22.9 x H21.5 in, which offers support and allows it to be raised above ground level. The featured design is ideal for the outdoors and all tough environments.
Even though this device may be technically portable (as in movable), manipulation and transportation without special equipment can be a challenge, as it weighs 105 pounds. 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.
Monitoring of the PM4500's status and activity is made possible by a digital data center, which provides information on the lifetime run hours and is one of the features of its control panel.
A built-in fuel gauge allows for a quick, easy and convenient check of the fuel level of the generator.
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 PM4500's packaging.
The Powermate PM4500 is EPA-approved and CARB-compliant. Therefore, its sale and purchase are permitted in all of the 50 states, including California.
Moreover, it features a spark arrestor, which makes it suitable for use in forested areas.
The Powermate PM4500 versus other generators
The following charts are provided to give you an idea of how some of the key specs of the Powermate PM4500 compare to generators of similar power (between 3500 and 4500 W).
- Having a dry weight of 105 lbs, the Powermate PM4500 belongs in the expected weight range for generators which produce 3500 to 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.
- Offering up to 19 hours of running time on a full tank at 25% load, the PM4500 is within the average autonomy range of similarly powerful generators. Concerning the run times, one of the several devices with a comparable output, offering the highest autonomy, is the Firman W03661OF, which is able to run for 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. Compared to its peers, this generator is not exactly fuel efficient, compared to similarly powerful devices, with an estimated fuel consumption of 0.26 GPH at a 25% load. If not satisfied with the afore-mentioned fuel consumption, you may wish to check out the Champion 200988. With a fuel consumption of as little as 0.16 GPH, it is one of the most efficient generators currently on the market.
As you can see from this interactive chart, when compared to other 3500-4500W generators, the Powermate PM4500 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.
The bottom line
- GFCI Outlets
- Decent weight (105 lbs)
- Decent run time
- No electric start
- Low fuel efficiency

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. In 2009, they have signed under what they call “partnership” (more accurately ownership) with the Italian PRAMAC. In 2014, Generac acquired Powermate from PRAMAC.
The Powermate PM4500 is covered under a warranty for up to 3 years. This warranty may be limited and may not cover all parts of the generator.
