Summary
The Champion Power Equipment 201501 3650-Watt RV Ready Portable Generator with CO Shield® offers versatile and convenient power, featuring a 224cc engine, 4550 starting watts, 3650 running watts, and up to 14 hours of run time at 50% load. It includes CO Shield® carbon monoxide auto shutoff system, making it ideal for camping, home backup, and more.
The Firman P03628 is a 3,650-watt running generator built on a 208cc OHV 4-stroke engine with cast iron sleeves. This wattage class handles mid-range household loads: refrigerators, window air conditioners, well pumps, and power tools, but not simultaneous heavy-draw appliances like central AC or electric ranges. The 4,550-watt peak gives it startup headroom for motors and compressors. Gasoline fuel means easy refueling at any station, and the 5-gallon tank stretches to 14 hours at half load, reducing refueling frequency on job sites or during extended outages. The RV-ready outlet configuration and remote start make this a practical choice for both emergency backup and recreational use.
