With 10,500 running watts on gasoline and 9,500 on propane, it can handle multiple household appliances during outages. Its 9.5-gallon fuel tank offers up to 19 hours of runtime, which means fewer refills and longer operation in emergencies. The generator is powered by a durable 500cc 4-stroke engine with features like automatic low oil and carbon monoxide shutdowns, adding safety and engine protection.

One of its best conveniences is the remote electric start, letting you power it up without leaving your home. It also includes a recoil start as a backup. The unit weighs 230 pounds, which is fairly heavy but typical for this power size; it’s portable enough with some effort but not something you’d move around frequently.

All outlets have rubber covers for added safety.

The generator comes ready to use right out of the box with included accessories like a battery charger, oil, and tools. Plus, it has useful extras like a fuel gauge, USB port, and an hour meter to track usage. Backed by a 3-year warranty and nationwide support, it is a solid option for those who want peace of mind during power outages.
