Zoom on the Powermate PM4500
In summary, the Powermate PM4500 is a portable generator especially useful for:
- RV travellers wishing to enhance their freedom and nomad lifestyle
- People occasionally participating in outdoor fairs, festivals or events
- 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, the extra features it benefits from, and any relevant emission compliance details.
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.
Its starting mechanism is based on a conventional pull-start mechanism. It features Powermate's PowerDial™, an easy-to-use dial with three operation settings.
Thanks to a fuel capacity of 5 gallons, the PM4500 can operate for up to 19 hours with a full tank (fuel consumption around 0.26 GPH).
The control panel includes the following 5 AC outlets:
Even if this Powermate generator isn't quite RV Ready, it still allows for an easy RV connection via an L5-30P to TT-30R adaptor, thanks to its L5-30R receptacle.
With its dimensions of L26.3 x W22.9 x H21.5 in, the conventional, open frame design of the Powermate PM4500 offers stability and allows the generator to be raised above ground level. The generator is designed for ideal use outdoors and in rough environments.
Although this generator is technically considered 'portable' (in the sense that it can be moved), its 105 lbs make it incredibly difficult to manually lift and transport. However, its challenging mobility is solved by its wheel kit (⌀8") and its folding handle, which will ease its displacement, once it is on the floor.
One of the many PM4500's features is the data center, included in its control panel, which conveniently provides information on the lifetime run hours and thus, helps you monitor its activity and status.
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 and therefore, can be used 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. In terms of weight, one of the champions in their power range is the WEN GN400i, standing at just 66.1 lbs.
- 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. Concerning the run times, one of the several devices with a comparable output, offering the highest autonomy, is the Champion 200954, which is able to run for 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. 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 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.
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
- High run time
- Decent weight (105 lbs)

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.
