Summary
The Champion Power Equipment 201267 is a 3550-watt portable generator designed for reliable power during outages or outdoor activities. It features a 224cc OHV 4-stroke engine, providing 3550 running watts and 4450 starting watts. The generator includes a 4.7-gallon steel fuel tank, offering up to 14 hours of runtime at 50% load. It is RV ready and equipped with multiple outlets, including a 120V 30A (TT-30R) outlet, making it suitable for various applications.
The Firman P03503 is a 3,550-watt gasoline generator built around a 208cc OHV 4-stroke engine with a cast iron sleeve. This wattage handles mid-range household loads: a refrigerator, microwave, and several outlets running simultaneously, or a modest RV power setup. The 5-gallon fuel tank delivers 14 hours of runtime at 50% load, meaning a full tank covers a typical overnight camping trip or a daytime power outage without refueling. The 4,450 starting watts give it enough surge capacity to turn on air conditioning compressors or well pumps, making it practical for both emergency backup and recreational use.
