Buying Guide: How To Choose The Right Portable Generator For Home Backup
What load do you need to support?
List the essential appliances and devices you want to run during an outage. Then match running watts to power those items. For larger homes, prioritize higher running watts and a model with transfer-switch compatibility.
Fuel flexibility matters
Consider whether you want gas-only, dual fuel, or tri-fuel capability. Dual- and tri-fuel options give you flexibility during fuel shortages and allow you to select the most economical option at the time.
Portability vs. power
Smaller units are easier to move and store but deliver less power. Larger generators provide more watts and longer runtimes but require more space and setup.
Runtime and fuel tank size
Longer runtimes reduce refueling disruptions during outages. Compare fuel tank capacity and run-time at a given load to estimate daily needs during outages.
Outlets and safety features
Check for necessary outlets (120V, 240V, RV, USB) and safety features like rubber outlet covers, CO sensors, low-oil shutoff, and remote start capabilities for ease of use and safety during operation.
Noise level and emissions
In residential areas, noise and fumes matter. Inverter generators generally run quieter and cleaner than traditional open-frame models, and LiFePO4-based power stations avoid fuel emissions altogether.
Transfer switch readiness
For home backup with a dedicated circuit panel, ensure the unit is transfer-switch ready or compatible with an automatic transfer switch for seamless power during outages.
