Summary
The Cat RP12000 E is a 12,000-watt gasoline generator built for job sites, construction crews, and homeowners who need sustained power for multiple heavy tools or appliances simultaneously. The 15,000-watt peak output handles startup surges from air compressors, circular saws, and welders without stalling. At 350 pounds, this is a stationary or semi-portable unit. It ships with a wheel kit, battery charger, and full tool set, meaning users can operate it immediately without additional purchases.
The Predator 71341 is a 1400-watt gasoline generator built for portable power in situations where you need steady electricity without the weight penalty of larger units. At 60 lbs, it sits at the threshold between grab-and-go portability and genuine stationary capability. The 1400-watt running output powers small job sites, RV setups, and home backup scenarios. Think laptop charging, power tools, small refrigerators, and LED lighting running simultaneously. The 1800-watt starting capacity handles the surge when compressors, pumps, and air conditioners first engage. Gasoline fuel means you refuel at any gas station and operate in remote locations where propane or natural gas lines do not exist.
