Summary
The Champion Power Equipment 201438 is a 10,000-watt Tri-Fuel portable generator equipped with CO Shield® technology, capable of operating on natural gas, propane, or gasoline.
The Cat RP6500 E is a 6500-watt gasoline generator built for residential backup and light commercial work. Its 8125-watt peak capacity means it can start large tools and appliances that draw high inrush current, then sustain 6500 watts of continuous power for multiple devices simultaneously. A 7.9-gallon fuel tank delivers 12 hours of runtime at 50% load, which translates to roughly one full workday or overnight backup without refueling. The gasoline engine is straightforward to maintain and refuel anywhere, making this unit practical for job sites, outdoor events, and emergency home power.
