In the sections ahead, the power characteristics, availability of various outlets, the portability, and any additional features of the device shall be discussed.
Power & Run Time
Featuring a 224 cc Generac OHV 4-stroke engine, the Powermate PM4500 operates using gasoline, providing 120V, with a running wattage of 3,600W and a starting wattage of 4,500W.
This generator utilizes a classic hand-operated recoil starting mechanism for startup. 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).
Outlets
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.
Portability
Measuring L26.3 x W22.9 x H21.5 in, the classic open frame construction of the Powermate PM4500 provides stability while enabling convenient maintenance access to components and adequate air cooling. The generator is designed for ideal use outdoors and in rough 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. However, the limited maneuverability is remedied with its wheel kit (⌀8") and its folding handle, facilitating convenient shifting once the generator is positioned on the ground.
Features
Featuring a digital data center on its control panel, the PM4500 offers you convenient access to essential information about the lifetime run hours, facilitating effective monitoring of its activity and status.
Thanks to its built-in fuel gauge, the generator allows you to quickly, conveniently, and easily check the gas level at a glance.
From a security point of view, the generator is equipped with an overload protection (circuit breaker) and an automatic low oil shut-off, giving you a peace of mind during use.
In addition to the standard documentation and owner's manual (opens in a new tab) for prompt setup, Powermate has also included some oil in the packaging of the PM4500.

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).
- As its weight is 105 pounds, the Powermate PM4500 falls in the expected weight range of the devices in the 3500-4500 rated wattage category. In terms of weight, one of the champions in their power range is the WEN 56432iX, standing at just 52.9 lbs.
- At 25% load, the PM4500 achieves one of the longer run times compared to devices of similar power, sustaining operations for up to 19 hours. If prolonged run time is essential to your needs, you could consider the Firman WH03662OF, which offers one of the highest autonomy among devices with similar power output, lasting up to 25 hours.
- While run time is vital, it hinges on the fuel capacity. To grasp the full picture, we must also factor in fuel efficiency. 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 201319 is a device you could look out for.
Price comparison
As you can see from these interactive charts, when compared to other 3500-4500W generators, the Powermate PM4500 is on the average side of the price range.
Therefore, this generator nicely fits in the expected budget for this kind of product.
The bottom line
