Zoom on the Powermate PM4500
In summary, the Powermate PM4500 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 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
The Powermate PM4500 houses a 224 cc Generac OHV 4-stroke engine, which provides 120V, consumes gasoline and delivers a running wattage of 3,600W along with 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 full tank, the PM4500 can operate for up to 19 hours (fuel consumption around 0.26 GPH), thanks to its fuel capacity of 5 gallons.
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.
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. This type of design is ideal for tough environments and heavy outdoor use.
While the generator is considered to be technically 'portable' (in the sense that you can move it), manually lifting and transporting it may be challenging, due to its high weight of 105 lbs. 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.
The control panel of the PM4500 includes a digital data center, which assists you in monitoring its status and activity, as it provides information on the lifetime run hours.
The generator allows for a quick, easy and convenient assessment of its gas level, as it is equipped with a built-in fuel gauge.
From a security standpoint, the product offers an automatic low oil shut-off and an overload protection (circuit breaker), allowing you to 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 thus, may 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. If you are concerned by weight, one of the champions in the above-mentioned power range is the Genmax GM4600iAEFIC, with a dry weight of just 58.4 pounds.
- 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. Furthermore, considering the run times, one of the generators which have a roughly same power output, with the highest autonomy, is the Firman W03661OF, as it provides up to 25 hours.
- Run times are important, yet thanks to their dependence on the fuel capacity, they should be judged along with the fuel consumption of the device. 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 you are concerned with gasoline efficiency, having a fuel consumption of just 0.16 GPH, the Champion 200988 is a device you could look out for.
As you can see from these interactive charts, 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.

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.
