Buying Guide
What sized generator do I need?
Calculate your essential loads (refrigerator, lighting, sump pump, modem, and select appliances). Aim for a generator that can handle peak simultaneous loads plus 20–30% headroom. For home backup, consider models with 8,000–12,000 running watts for midsize homes; for larger homes or RVs, 12,000–20,000 running watts or higher may be necessary.
Why choose dual fuel?
Dual fuel provides flexibility when one fuel type isn’t available. Gasoline is common but propane can offer longer shelf life with less odor and can store longer. If you expect irregular fueling opportunities, a dual-fuel model helps ensure you’re never without a power source.
Key safety considerations
- Always operate generators outdoors in a well-ventilated area to avoid carbon monoxide buildup.
- Use transfer switches or manual disconnects to safely connect to home electrical systems.
- Regularly check oil, fuel, and battery (for electric starts) to prevent startup issues.
- Keep generators away from doors and windows to reduce exhaust intrusion.
Operating features to look for
- Remote start or electric start for ease of use.
- CO sensor or shutdown feature for added safety.
- Multiple outlets including 20A, 30A, and RV-ready 120/240V receptacles.
- Fuel gauge, long run time, and efficient engine design for better reliability.
Maintenance and longevity considerations
Choose models with durable engines, robust framing, and accessible service centers. Regular oil changes, air filter checks, and proper storage extend life. Look for models with a warranty that covers major components and a modular design for quick part replacement.
