Buying Guide: How to Choose a Dual-Fuel Portable Generator
- Power needs: List essential appliances and their wattage. Choose a unit with higher peak watts and continuous running watts to cover startup surges.
- Fuel flexibility: Dual-fuel models give you gasoline and propane options. Propane often stores longer and can be cheaper, but power output and runtime vary by fuel and altitude.
- Safety features: Look for CO sensors, automatic shutdown, and proper outlet covers. Inverter technology reduces THD for electronics safety.
- Portability versus capacity: Heavier units deliver more power; smaller units are easier to transport but may require frequent refueling or limitations on load.
- Outlets and RV readiness: Ensure the generator has the right outlets (24-50A RV plug options, 120V outlets) for your setup. A transfer switch-ready unit is ideal for home backup.
- Runtime and fuel management: Consider tank size and efficiency, especially if you expect prolonged outages. Propane tank management and hose quality matter for safety.
- Noise level: Inverter generators generally run quieter (often 50-65 dBA). If you’re in a shared space, prioritize noise considerations.
