Buying Guide
Choosing a budget inverter generator involves balancing power needs, fuel flexibility, noise tolerance, and portability. Start by estimating your essential running watts (refrigerator, lights, chargers, small appliances) and add a cushion for surge watts to handle startup loads. Dual-fuel models offer flexibility when gasoline is scarce or propane is more convenient for longer outages. Look for clean sine-wave output (low THD) to protect electronics, and safety features such as a CO shutdown sensor.
Portability matters: lighter units with wheels are easier to move, but some higher-watt models will be heavier. ECO or economy modes help maximize runtime on fuel, especially for extended outages. For home backup, consider transfer-switch readiness or interlock kits to simplify connection to a panel. Warranty length and service availability are practical considerations, especially when choosing a budget option intended to last several seasons.
