Buying Guide: Key Purchase Considerations
- Power needs: Match peak and running watts to the devices you plan to run. Consider future needs like a refrigerator, sump pump, and essential electronics.
- Fuel type and availability: Gasoline engines are common, but dual-fuel options offer propane compatibility for longer outages. Check tank size and expected runtime at typical loads.
- Portability vs. capacity: Open-frame and inverter generators vary in weight and ease of transport. Weigh the need for mobility against total wattage and run time.
- Inverter technology and clean power: Inverter generators provide stable, clean power suitable for sensitive electronics. Look for low total harmonic distortion (THD) specs where available.
- Noise level: Quiet operation matters for campgrounds and neighborhoods. ECO or smart-mode features help reduce noise and conserve fuel at lower loads.
- Outlets and RV compatibility: Ensure sufficient outlets (120V, 30A RV, etc.) and check for transfer switch readiness if you plan to connect to a home panel.
- Start method and controls: Remote start or electric start can add convenience; recoil starts may be sufficient for occasional use and backups.
- Maintenance and safety: Look for automatic low-oil shutoff, hour meters, and CO sensors where applicable to protect equipment and users.
- Warranty and support: Consider model availability, parts, and manufacturer support in your region for long-term reliability.
