Buying Guide
- Power needs: Match starting and running watts to your essential appliances. Refrigerators, sump pumps, and lights may require higher running watts during outages.
- Fuel and runtime: Gas units are common and easy to refuel, while dual-fuel models offer propane as an alternative, potentially extending run time in emergencies.
- Noise levels: If you’ll use the generator near living spaces or campgrounds, look for models in the 50–75 dB range with quiet technology and proper muffling.
- Safety features: CO sensors, auto shutoff, and low-oil indicators protect household members and equipment during operation.
- Portability: weight and wheel kits influence portability. Lightweight inverter generators are easier to move but may offer less power than larger jog-site units.
- Outlets and compatibility: Ensure the generator has RV-ready outlets, multiple 120V outlets, and optional parallel kits if you anticipate needing extra power.
- Fuel capacity and efficiency: A larger fuel tank reduces refueling frequency during extended outages; ECO modes improve fuel economy in light-load scenarios.
- Maintenance: Look for dealers with clear warranty terms and availability of replacement parts and accessories.
