Description
The Powermate PM4500E is made with a gasoline-powered Generac OHV 4-stroke engine that is 224 cc. It has a 120V output and a running power of 3,600W and a peak power of 4,500W. This generator has a simple pull-start mechanism, but it also has an electric starter that is easy to use (battery included). With a full tank, the PM4500E can run for up to 20 hours (using about 0.25 GPH of fuel), because it has a 5 gallon fuel tank.
Outlets
On the control panel, there are 5 AC outlets for: Two 120V 20A (5-20R) GFCI duplex outlets and two 120V 30A (L5-30R) duplex outlets.
Even though this Powermate generator isn’t quite RV Ready, its L5-30R receptacle makes it easy to connect to an RV with an L5-30P to TT-30R adaptor.Features
The PM4500E’s control panel has a digital data center that helps you keep track of its status and activity by giving you information about how long it has been running.
The generator has a built-in fuel gauge that makes it easy to see at a glance how much gas is in the tank.In terms of safety, the generator can be used without worry because it has a circuit breaker for overheating and an automatic shut-off when the oil level gets too low.Powermate packed the PM4500E with the usual paperwork and owner’s manual to get you up and running quickly.They also included some oil.Mobility
The Powermate PM4500E is 26.3 inches long, 22.9 inches wide, and 21.6 inches high.
It has a typical open frame design that makes it stable and allows it to be raised above ground level.The device was made to work well in harsh conditions and in the great outdoors.The generator weighs 114 pounds, so it may be hard to move or transport it by hand, even though it is technically a “portable” generator (movable).But its 8″ wheel kit and folding handle make it easier to move once it’s on the floor.Product Videos
The following charts show how some of the most important features of the Powermate-PM4500E compare to other generators with the same power output.
**Fuel efficiency is give in relative percentage, 0 being the lowest and 1 being the highest value. Please see below specification table for actual value.

- We compared more than 500 portable generators at 50% load. We found that there is “skewed right” distribution for the difference between 50% load and 25% load and the median comes at 1.43. With this number we converter all the 25% load runtime to 50% load. Same with the propane efficiency, where median is 1.38.
- For some generators where propane runtime was not given, we used NIST 1994 GGE (Gasoline Gallon Equivalent) formula: 5.66 lbs. of propane = 1 gal of gasoline. All propane runtime is for 20 lbs. propane tank (4.7 gallons).
- Unlike many other sites, we actually tried to find out information about each of the above requirements. However, we are human and are therefore capable of the odd oversight or mistake. Please let us know if you spot any missing or erroneous values so that we can fix them.
About the Manufacturer
While Powermate’s past is a little mysterious, they assert to have been selling portable generators and other outdoor power equipment for over 40 years.
In 2009, they negotiated a contract for what they refer to as “collaboration,” but is actually ownership with the Italian company PRAMAC, which Generac later purchased from PRAMAC in 2014.Warranty Information
A warranty covers the Powermate PM4500E for up to 3 years.
This warranty may not cover all parts of the generator or may only cover certain parts.Check out Powermate’s warranty policies if you want to know more about the warranty on Powermate generators.You can also call their customer service line at 1-800-445-1805.
