The Cat RP3600 has a 212cc OHV 4-stroke engine that runs on gasoline and puts out 120V and 3,600W while running and 4,500W at its most powerful. The generator has a pull-start mechanism that is common. With a full tank, the RP3600 can run for about 13.5 hours at 0.5 load (using about 0.33 GPH of fuel). This is because it has a 4.5-gallon fuel tank.
The control panel has 5 AC outlets: two 120V 20A (5-20R) duplexes and a 120V 30A (TT-30R) plug-in.The TT-30R plug on this Cat generator is ready for an RV.TT stands for “Travel Trailer”.
The status and activity of the RP3600 can be easily checked on the control panel, which has a meter that shows voltage, frequency, and lifetime hours.The LED lights on the panel give you even more control and make it easy to use at night.The generator has a built-in fuel gauge that makes it quick, easy, and convenient to check how much gas is in it.From a safety point of view, the product has an automatic shut-off for low oil and an overload protection (circuit breaker), so you can use it without worrying.The Cat RP3600 comes with the basic paperwork and an owner’s manual, which makes it easy to start the generator.It also comes with a tool kit, a funnel, and oil.You can also buy a storage cover that is made by the company.
With dimensions of L28.4 x W25.2 x H23 in, the Cat RP3600 is a traditional, open-frame generator that is stable and can be raised above ground level.The design shown is great for the outdoors and other rough places.The generator weighs 125 pounds, so it may be hard to move or transport it by hand, even though it is technically a “portable” generator (movable).Still, once it’s on the ground, its wheels and folding handle make it easy to move.
The following charts show how some of the most important features of the Cat-RP3600 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
Caterpillar Inc., frequently referred to as just CAT, is an American engineering company with a line of goods that includes power generators, financial products, mobile phones, and machines.The 1925-founded business is listed among the Fortune 500 and serves as a pillar of the US Dow Jones index.CAT offers a variety of portable and household-scaled devices in addition to its primary concentration on industrial scale generators.Northern Ireland’s Belfast and Illinois’s Mossville collaborate to develop CAT portable generators.However, China is where they outsource its manufacture.
The warranty for the Cat RP3600 lasts for up to 2 years.This warranty may not cover all parts of the generator or may only cover certain parts.Check out Cat’s warranty policies if you want to know more about the warranty on Cat generators.You can also call their customer service line at 1-844-PWR-ME-UP (844-797-6387).
