Buying Guide: Key Considerations For American-Made Portable Generators
- Fuel flexibility: Tri-fuel and dual-fuel models offer extended run-time and versatility, but consider the availability and storage of each fuel type in your area.
- Power needs: Assess essential appliances and tools. Choose a unit with peak wattage above the sum of your critical loads to avoid overloads.
- Engine and durability: Look for cast-iron sleeves and heavy-duty OHV engines for long-term reliability in frequent use.
- Starting method: Remote electric start is convenient for frequent outages; recoil start is simpler and lower maintenance.
- Outlets and transfer switches: Ensure outlets match your home or RV needs and verify transfer switch compatibility for seamless house integration.
- Run time and fuel capacity: Larger fuel tanks extend outage resilience but increase unit weight and footprint.
- Portability vs. power: Inverter models offer cleaner power and better fuel efficiency but often have lower peak wattage than open-frame types.
Frequently Asked Questions
