Zoom on the Powermate PM4500
In a nutshell, the Powermate PM4500 is a portable generator mostly geared towards:
- 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 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's core is the 224 cc Generac OHV 4-stroke engine, which runs on gasoline. With an output of 120V, it provides a running wattage of 3600W and 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.
The PM4500 can operate for up to 19 hours with a full tank (fuel consumption around 0.26 GPH), due to its fuel capacity of 5 gallons.
The control panel includes the following 5 AC outlets:
While this Powermate generator is not RV Ready, its L5-30R receptacle can be used for a simple RV connection with an L5-30P to TT-30R adaptor.
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. This type of design is ideal for tough environments and heavy outdoor use.
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, this lack of maneuverability is compensated by its wheel kit (⌀8") and its folding handle, with which you can conveniently shift it, once it's on the ground.
To help you monitor the PM4500's status and activity, its control panel is equipped with a digital data center, giving you information on the lifetime run hours.
Thanks to a built-in fuel gauge, the generator allows you to quickly, conveniently and easily check the gas level at a glance.
As far as security is concerned, the generator can be used with a peace of mind, as it features an automatic low oil shut-off and an overload protection (circuit breaker).
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 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).
- At a weight of 105 pounds, the Powermate PM4500 places in the expected weight range of the generators in the 3500-4500 rated wattage range. If weight matters to you, one of the champions in this power range is the WEN GN400i with only 66.1 pounds.
- As the PM4500 features an autonomy of up to 19 hours at 25% load, it has a higher run time than an average generator of its power range. Concerning the run times, one of the several devices with a comparable output, offering the highest autonomy, is the Champion 200914, which is able to run for up to 22 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. 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.
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)
- 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.
