The Generac GP8000E delivers 8,000 running watts with a 10,000-watt surge capacity — enough to power your refrigerator, well pump, central air conditioner, lights, and several outlets simultaneously. The electric start is standard, and the large 7.9-gallon tank gives you roughly 10 hours of runtime at 50% load.

2. Honda EU7000iS — Best Quiet Generator
Running at just 52–58 dB, the Honda EU7000iS is quieter than a normal conversation. Its inverter technology produces clean, stable power safe for computers, medical equipment, and modern appliances. Honda Eco-Throttle automatically adjusts engine speed to match the load, extending runtime and reducing fuel use.
3. Champion 100813 — Best Value Pick
The Champion 100813 delivers 8,500 running watts at a price that undercuts most competition. Its dual-fuel capability lets you run on gasoline or propane — a major advantage when gasoline is scarce after a major storm. Cold Start Technology ensures reliable starting down to -20 degrees Fahrenheit.
What Size Generator Do You Need?
- Essential circuits only: 3,000–5,000 watts
- Essential + window AC: 5,000–8,000 watts

- Whole-home standby (automatic): 16,000–22,000 watts
Key Features to Look For
Transfer Switch Compatibility
A transfer switch is essential for safe home backup operation. It disconnects your home from the utility grid before connecting the generator, preventing dangerous back-feeding that can injure utility workers and damage appliances. Never connect a generator directly to your home wiring without a proper transfer switch.
Runtime and Fuel Tank Size
Multi-day outages are increasingly common. Look for generators that offer at least 8–10 hours of runtime at 50% load. Dual-fuel capability gives you flexibility when one fuel source is unavailable after a storm.
Final Recommendation
For most homeowners, the Generac GP8000E offers the best combination of power, reliability, and value. If budget is a priority, the Champion 100813 delivers comparable performance at a lower price. And if quiet operation is critical, the Honda EU7000iS is the best in class. Whatever you choose, buy before the next storm season — generators sell out fast when disaster strikes.
