Summary
The A-iPower GXS8200D is a 6,500-watt dual-fuel generator built for users who need flexible fuel options and extended runtime. On gasoline, it delivers 8,200 starting watts and 6,500 running watts. On propane, it steps down to 7,400 starting watts and 5,900 running watts. This power level handles most household circuits, job site tools, and RV systems simultaneously. The dual-fuel design means you can switch between gasoline and propane depending on what you have on hand and which fuel offers better economics for your situation. The 6.3-gallon tank runs for 17 hours at 25 percent load on gasoline, which translates to weeks of occasional use before refueling becomes a concern. At 50 percent load, the runtime extends even further on propane. The 322cc OHV 4-stroke engine with cast iron sleeve is built for durability in outdoor conditions. This is a workhorse for homeowners, contractors, and RV owners who value fuel flexibility over absolute portability.
The Powermate PM9400E is a portable generator offering 9,400 starting watts and 7,500 running watts, equipped with a Generac 420cc OHV engine and an 8-gallon fuel tank, providing up to 13 hours of runtime at 25% load.
