Buying Guide
What to consider when selecting a 3500-watt propane generator:
- Fuel flexibility: Dual-fuel units offer greater fuel availability and cost options during extended outages or remote camping.
- Power needs: Compare peak watts vs. running watts to ensure you can handle your essential devices without overloading the generator.
- Inverter vs. conventional: Inverter generators provide cleaner power (low THD) and are better for sensitive electronics, though some models prioritize portability over peak output.
- Noise levels: Look for quiet operation if you’ll use the generator in campsites, residential neighborhoods, or parks. CO sensors add a safety layer for enclosed spaces.
- Portability: Consider weight, wheels, and handles. Some models include automatic fuel-switching and easy-start options for convenience.
- Runtime and fuel capacity: Longer runtimes reduce refueling frequency. Propane storage should be planned for extended outages or trips.
- Outlets and compatibility: Check outlets for RV compatibility (TT-30R or NEMA 5-20R) and ensure there are USB and DC options if needed.
