Power production and Run time

A Gasoline-Fueled 420 Cc Ohv 4-Stroke Engine Is Included In The Design Of The Cat Rp6500 E. It Has A Running Wattage Of 6500W And A Peak Wattage Of 8125W With A 120/240V Output.

This Generator Has A Classic Pull-Start Mechanism and a Convenient And Easy-To-Use Electric Starter (Battery Included). The Rp6500 E Has A Fuel Capacity Of 7.9 Gallons And Can Run For About 12 Hours At 50% Load With A Full Tank.


Although the Cat generator is not RV ready, its L5-30R receptacle may be utilized with an L5-30P to TT-30R converter for a simple RV connection. Furthermore, because it has a twist-lock L14-30R receptacle, the RP6500 E is transfer switch ready: you can quickly connect it to your breaker box to power your house during a power outage.


The Cat RP6500 E’s dimensions, L32.9 x W27.4 x H24.7 in, and its usual open frame construction give stability and allow the generator to be lifted above ground level. This design is excellent for harsh situations and extensive outdoor use.

While the generator is theoretically ‘portable,’ manually lifting and carrying it may be difficult due to its heavy weight of 202 lbs. However, its difficult mobility is overcome by its wheel kit and folding handle, which will simplify its movement once on the floor.


The Cat RP6500 E meets EPA and CARB requirements. As a result, its sale and purchase are legal in all 50 states, including California.


A two-year guarantee protects the Cat RP6500 E. This warranty may be restricted and not cover all of the generator’s components.
