Our take on the Generac GP 6500 Watt Portable Generator

The Generac GP6500 is a gasoline portable generator rated at 6,500 running watts and 8,125 starting watts, enough to back up a home's essentials or run a jobsite. It uses a 389 cc OHV engine, a 7.9-gallon steel tank with a fuel gauge, and Generac's PowerRush starting boost. It is a recoil-start, non-inverter unit at 172 lb, so it is loud and heavy but simple. Its best new price is $827 at FactoryPure as of November 4, 2026, with 5 stores listing it new.

Questions and answers

Is the GP6500 worth it over a smaller generator?
If you need to run a well pump, a window AC or a 240V circuit, the 8,125 starting watts are the reason to pick it. For lights and a fridge only, a smaller, lighter unit will do.
Can it run a house during an outage?
It can carry essentials through a transfer switch, not a whole house at once. Add up running watts and check that motor starting loads stay under 8,125.
Does it have electric start?
No. The GP6500 is recoil start only. Generac's electric-start models cost more and add a battery.
How long does it run on a tank?
About 11.5 hours at 50% load on the 7.9-gallon tank. Expect closer to 8 hours at heavier loads.
Is it safe for TVs and laptops?
It is not an inverter generator, so power is less clean. Use a surge protector or a UPS for electronics, or choose an inverter model.
When is it cheapest?
Portable generators tend to discount before storm season and around late-spring sales. The best new price seen is $827 at FactoryPure as of November 4, 2026.
