Choosing the Best Fuel Injected Generator: Key Buying Tips
Fuel Type Flexibility
If you’re in an area with inconsistent fuel availability or want to be prepared for any situation, choose a dual fuel or tri-fuel generator. These models give you the freedom to use propane, gasoline, or even natural gas.
Inverter vs. Conventional
- Inverter Generators: Quieter, more efficient, and safe for sensitive electronics.
- Conventional Generators: Heavier, more powerful, and better for whole-home backup or industrial use.
Power Output Needs
Always size your generator according to your highest load requirement. For home backup, consider units above 10000W, while for RVs or tailgating, models under 4000W may suffice.
Safety & Convenience Features
Look for:
- CO Detection
- Push-Button or Remote Start
- Fuel Gauge & VFT Displays
