What can the GP8000E power during an outage?

It handles essentials like a fridge, freezer, furnace fan, lights and sump pump, and PowerRush helps start motor-driven appliances. Central air and whole-house loads are beyond it.

How long does it run on a full tank?

Generac rates it at up to 11 hours at 50% load. Heavier loads shorten that.

Does it come with a battery for electric start?

Yes, the starting battery is included, and a plug-in jack keeps it charged between uses.

Is it safe to run indoors or in a garage?

No. Gas generators produce carbon monoxide and must run outdoors, well away from windows and doors.

How does it compare with the GP6500?

The GP8000E offers more running and starting watts and the same electric start, so it suits larger loads. The smaller unit is easier to move.

What maintenance does it need?

Regular oil changes, spark plug checks and fresh fuel. The hour meter shows when service is due, and low-oil shutdown protects the engine.

Our take on the Generac 10,000 Starting Watt Portable Gas Generator

The Generac GP8000E is a gas-powered portable generator with electric start and PowerRush technology that adds starting capacity for motors and appliances. It runs on a large steel fuel tank with a gauge, giving up to 11 hours at half load, and rides on never-flat wheels with a fold-down handle. Low-oil shutdown, covered outlets and an hour meter with maintenance alerts round it out. It suits homeowners who want backup power for outages and occasional job-site or recreational use, and it competes with other 8,000-watt-class portables on electric start and runtime rather than on quiet operation.

About the Generac 10,000 Starting Watt Portable Gas Generator

It is intended for emergency power or recreational use. PowerRush Advanced Technology delivers over 30% more starting capacity, meaning extra electrical current on demand above the rated output when starting electric motors.

The outlets are covered for added protection. The wheels are heavy-duty and never go flat, and a fold-down handle makes the generator easier to move. A low-oil feature automatically shuts the generator down to prevent damage. A hardened 1.25-in. steel-tube cradle adds strength. An hour meter provides regular maintenance alerts.
