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.

Since I installed it, we haven't lost power once during storms. It fit perfectly with our home setup and it's incredibly easy to start and maintain. I recommend it completely. It's a really practical investment for anyone who wants peace of mind when the power goes out.

What I loved most was the design. It looks modern and sleek, and it blends in perfectly with the setup at home. It doesn't feel like a cheap, bulky unit — it's compact and fits right into the space. On top of being practical, it really improves the overall look of the backup power setup. Very satisfied with this purchase.
