Zoom on the Powermate PM4500
In a nutshell, the Powermate PM4500 is a portable generator mostly geared towards:
- RV travellers who wish to upgrade their experience to another level
- People occasionally participating in sporting competitions, open-air performances and outdoor festivals
- 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
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 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.
The generator features a conventional pull-start mechanism. It features Powermate's PowerDial™, an easy-to-use dial with three operation settings.
The fuel capacity of 5 gallons allows the PM4500 to operate for up to 19 hours with a full tank (fuel consumption around 0.26 GPH).
The control panel features the upcoming 5 AC outlets:
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.
The design of the Powermate PM4500 is a typical, open frame, with the dimensions of L26.3 x W22.9 x H21.5 in, offering support and stability and enabling the possibility of raising it above ground level. The featured design is ideal for the outdoors and all tough environments.
Since the generator weighs 105 lbs, it will be incredibly difficult to manually lift it and transport it, even though it is technically considered to 'be portable' (in the sense that it is movable). Nevertheless, thanks to its wheel kit (⌀8") and its folding handle (a decent solution to its lack of maneuverability), the generator can be easily moved, once placed 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.
The generator allows for a quick, easy and convenient assessment of its gas level, as it is equipped with a built-in fuel gauge.
As for its security measures, the device features an overload protection (circuit breaker) and an automatic low oil shut-off, 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. Thus, selling and purchasing this generator is allowed in each of the 50 states, including California.
Moreover, it features a spark arrestor, so it is adequate 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).
- Since the generator weighs in at a dry weight of 105 lbs, the Powermate PM4500 belongs in the expected weight range for devices which can produce between 3500 and 4500 rated watts. If you are concerned by weight, one of the champions in the above mentioned power range is the WEN GN400i, with a dry weight of just 66.1 pounds.
- Since the PM4500 boasts with a run time of up to 19 hours at 25% load, it can be safely judged as a device of a higher run time than most generators of a comparable output. 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.
- While the run time is an important parameter, it is dependent on the fuel tank’s capacity and thus, doesn’t say much on its own unless we consider fuel consumption as well. This generator is somewhat less fuel efficient than devices of comparable output: its estimated fuel consumption reaches 0.26 GPH at a 25% load. If fuel consumption is your top priority, we suggest to check out the Westinghouse iGen4200, which has a fuel consumption of only 0.14 GPH and thus, is one of the most efficient devices in our database.
The bottom line
- GFCI Outlets
- High run time
- Decent weight (105 lbs)
- No electric start
- Low fuel efficiency

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.
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.
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.
