| 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 Briggs & Stratton 30737 is a 5000-watt gasoline generator built for homeowners and job site operators who need extended runtime without constant refueling. With 5000 running watts and 6250 peak watts, this unit can power a refrigerator, multiple lights, and power tools simultaneously, making it suitable for emergency backup or outdoor work. The 7.5-gallon fuel tank delivers 12 hours of runtime at half load, which means a full day of operation before refueling becomes necessary. This is a stationary-duty machine. At 184 pounds, it requires wheels or multiple people to move, so placement matters before startup. |
