Buying Guide: Key Purchase Considerations

  • Fuel flexibility: Dual- or tri-fuel options provide versatility, especially when fuel availability is uncertain. Consider how often you expect to switch fuels and the density of fuel sources in your area.
  • Starting method: Electric start with battery backup is convenient, but ensure the unit includes a reliable charging system and a robust battery. Consider manual backup options as a fallback.
  • Wattage and load management: Evaluate your essential loads (refrigerator, HVAC, lights, sump pump) and choose a unit with sufficient peak and running watts. For larger homes, tri-fuel models offer greater headroom.
  • Transfer switch readiness: A transfer-switch-ready model simplifies automatic backup power. Confirm compatibility with your home panel and local electrical codes.
  • Run time and fuel tank size: Longer runtimes reduce refueling frequency. Look at gallons per hour at typical loads to estimate outage duration you can support.
  • Safety features: CO shutoff, low-oil shutdown, and rubber outlet covers enhance safety. CO alarms and detection systems add an extra layer of protection.
  • Portability and durability: Heavy-duty frames, wheels, and handles affect mobility and resilience in outdoor environments and during storm-season transport.
  • Noise levels: Inverter-based units are generally quieter, which is beneficial for residential use and campgrounds. Consider decibel ratings at 23–25 feet when evaluating suitability.
  • Maintenance considerations: Availability of replacement parts, service networks, and warranty terms impact long-term reliability and total ownership costs.
  • Budget and space: Higher-witness wattage and tri-fuel capability add cost and space requirements. Plan for secure storage and safe ignition handling.
