    How many watts do I need for the generator to power my whole house during an outage?

    It depends on your appliances (fridge, AC, lighting, etc.). Generally, a model between 10,000–13,000 watts covers most of an average home's essential needs. We can help you calculate exactly how much you need based on your specific appliances.

    Does it only run on gasoline, or are there other options (like propane)?

    We have Dual Fuel models that run on both gasoline and propane, so you can choose whichever fuel is available. We also offer Tri-Fuel models that add natural gas — great flexibility, especially if gasoline runs out when you need it most.

    What's the warranty, and how much maintenance does it need?

    Warranty typically ranges from 1 to 3 years depending on the model, covering the engine and core components. Maintenance is simple: regular oil changes, filter cleaning, and spark plug checks every few months.

    Generac's GP4000 offers many benefits that make this model a favorite for emergency power or recreational use. The GP4000 offers dual fuel capability, running on gasoline or liquid propane fuel, with a fuel source selector for seamless switching. Powered by a reliable 224cc OHV engine with splash lubrication for a long engine life. This generator offers an 8 hour runtime on gasoline and 10 hour runtime on a 20 lb. LP tank when running at 50% load, ensuring reliable performance for extended periods. It comes with an ergonomic handle, never flat wheel kit, and durable steel-tube frame, while covered outlets protect from environmental conditions.


    Factory refurbished units are thoroughly tested by and ship directly from Generac. Most units look brand new, though some may have minor scratches/dents/dings.
