The gasoline-powered 224 cc OHV 4-stroke engine is the heart of the Pulsar PG4500iSR. It has a 120V output and a running power of 3,700W and a peak power of 4,500W. Also, since it can work in parallel (the PGiPAIRB3 parallel kit is not included), this power can be increased by connecting it to another unit that works with it. The noise level of the inverter generator is 64 dBA, which is just a little louder than an office. It has a simple pull-start mechanism and a simple and elegant electric starter (battery included). The PG4500iSR can also be started from a distance for added convenience (key fob included). With a full tank, the PG4500iSR can run for about 7 hours at 0.5 load (using about 0.46 GPH of fuel). This is because it can hold 3.2 gallons of fuel. As the PG4500iSR makes a clean sine wave with a Total Harmonic Distortion (THD) of 3%, you can safely plug sensitive electronics into the AC outlets.
On the control panel, there are 3 AC outlets: a duplex 120V 20A (5-20R) outlet and a 120V 30A (TT-30R) outlet.It also has 2 DC outlets: a 5V USB port for charging devices like phones and tablets, and a cigarette lighter-style 12V 8A outlet for charging batteries.This Pulsar generator is RV ready because it has a TT-30R plug.TT stands for “Travel Trailer”.
The lights on the device will show if the generator is too busy, if the oil level is too low, or if it is ready.For safety, the generator has an overload protection (circuit breaker) and an automatic low oil shut-off, so you can use it without worrying.Pulsar included a key fob with the PG4500iSR, along with the usual paperwork and owner’s manual to get you up and running quickly.
The Pulsar PG4500iSR is an inverter generator, and its closed design (L26 x W24 x H28 in) makes it look better than traditional devices with open frames.The generator has a modern look and is easy to use when generating power for fun.Even though this generator is technically “portable” in the sense that it can be moved, it is very hard to move by hand because it weighs 102 pounds.Once it is on the ground, it can still be moved easily with the help of its two 5″ wheels and telescoping handle.
The following charts show how some of the most important features of the Pulsar-PG4500iSR compare to other generators with the same power output.

- 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
A good selection of air compressors, pressure washers, and of course generators are available from Pulsar Products Inc., a firm situated in California, USA.Their models vary from 1,2 kW to 10 kW and include dual fuel and RV-Ready designs.The US is home to a number of Pulsar facilities, including two distribution centers, one in Illinois and one in California.However, it appears that Asia is where they outsource the production of their goods.
There is a warranty on the Pulsar PG4500iSR for up to 3 years.This warranty may not cover all parts of the generator or may only cover certain parts.Pulsar generators come with a warranty that you can learn more about by calling Pulsar Customer Support at 1-866-591-8921.
