| Summary | 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. | The Powermate CX3500 is a portable generator designed for various applications, including camping, picnics, tailgating, and emergency home backup. It features a Powermate OHV engine, digital multi-meter, low-oil level shutdown, and a fuel gauge. |
