Buying Guide
What to consider when choosing a dual-fuel portable generator:
- Power needs: Determine your essential loads and peak watts. If you want whole-home backup, target 12,000–13,000 watts or higher; for partial backups, 6,000–8,000 watts may suffice.
- Fuel availability and storage: Propane lasts longer and is stable; gasoline may require fresh fuel and stabilizers. Consider availability in your area and storage space.
- Starting method: Electric start is convenient, especially during cold outages. Manual start saves on electronics but can be harder to use in the field.
- Safety features: CO shutdown sensors, low-oil shutdown, and digital hour meters help prevent hazards and manage maintenance.
- Transfer switch readiness: If you plan to connect to a home panel, ensure the generator is transfer switch ready or compatible with your system.
- Portability vs. durability: Heavier units offer more stamina but are harder to move. Wheel kits and ergonomic handles improve portability.
- Noise and emissions: Consider decibel levels and regulatory limits, especially for residential use and urban settings.
