Summary
The Westinghouse iGen8200TFc is a 6,600-watt tri-fuel inverter generator built for homeowners and RV users who need flexible fuel sourcing and clean power for sensitive electronics. Its 8,200-watt starting capacity handles motor loads and air conditioning startup surges, while 3 percent THD protects laptops, TVs, and medical equipment from voltage spikes.
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.
