Buying Guide
Power needs: Determine your essential devices and total wattage requirements. If you expect to power multiple high-demand appliances (air conditioners, well pumps), consider models with higher peak watts or the ability to pair units in parallel. For smaller essentials, 3200W running watts may suffice. In inverter generators, peak watts account for startup surges, while running watts reflect sustained load.
Fuel choices: Tri-fuel options offer flexibility when one fuel source is scarce, but they can be more complex and heavier. If you primarily rely on gasoline, choose a model with efficient engine design and good fuel economy. If you have propane or natural gas readily available, tri-fuel capability can be a strong selling point for long outages.
Inverter versus open-frame: Inverter generators deliver clean power suitable for electronics and are typically quieter and more efficient. Open-frame models are often lighter and less expensive but may generate more noise and require more maintenance. For quiet suburban operation and sensitive devices, inverter units are generally preferable.
Runtime and fuel capacity: Longer runtimes reduce refueling frequency during outages. Check tank size and efficiency in gallons per hour at practical loads. ECO or economy modes extend runtimes by reducing engine speed when demand is low, but may slightly increase runtime under light loads.
Outlets and connectivity: Ensure the generator has the outlets you need (two 120V sockets, RV-ready 30A or 50A outlets, USB ports). If you have a home backup plan, verify transfer switch compatibility or interlock kit readiness. Parallel capability is valuable if you anticipate needing extra power later.
Safety features: Look for a CO sensor, low-oil shutdown, and proper voltage regulation (low THD) to protect electronics. A remote start or easy electric start can add convenience, especially during cold weather or emergencies.
Portability and warranty: Weight, dimensions, and handle design affect portability. If you plan to transport it often, factor in weight and ease of start. A solid warranty and accessible parts supply help reduce long-term maintenance costs and downtime.
Price and value: Budget-conscious buyers should compare total cost of ownership, including fuel economy, maintenance, and expected lifespan. The best value combines solid performance with reliable safety features and practical conveniences like RV ports and parallel capability.
