    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.

    From emergency home backup to DIY projects to the jobsite, the Generac GP15500EFI portable generator provides high wattage, dependable portable power. Equipped with an 816cc engine with Electronic Fuel Injection, the GP15500EFI delivers power efficiently, providing up to 11 hours of runtime at 50% load. TruePower™ Technology safely powers sensitive electronics, appliances and tools while onboard COsense® Technology provides powerful protection against hazardous carbon monoxide.

    The GP15500EFI also features electric start (battery included), low-oil shutdown protection, circuit breaker protected outlets and an hour meter with maintenance resets. The included never-flat wheel kit and available lifting eye accessory make transportation easy around the home or jobsite.
