Buying Guide: What to Consider in a Power Outage Generator
Power Output and Capacity
First, determine which appliances you need to run during an outage. Add up the wattage of essentials like your refrigerator, lights, and medical devices. For whole-home backup, a standby generator like the Generac Guardian 22kW or 26kW delivers 22,000 to 26,000 watts, easily powering an entire house.
Portable power stations, such as the Jackery HomePower 3600 Pro Max, offer 3,600Wh expandable to 43kWh, enough for several days of essential power. For smaller needs, the BLUETTI AC180 provides 1,152Wh and 1,800W output, ideal for running a fridge and a few devices. Consider your usage patterns to pick the right capacity.
Fuel Type and Recharge Options
Standby generators run on natural gas or propane, offering unlimited fuel as long as the supply lasts. They start automatically during an outage and require professional installation. In contrast, solar generators use renewable energy, recharging via solar panels, wall outlets, or car chargers. The BLAVOR 1600W even includes a built-in 40W panel for off-grid charging.
If you want fuel-free backup, solar generators are quiet and eco-friendly. For maximum reliability, a dual-fuel option might be ideal; explore our best 240V dual-fuel inverter generators for more choices.
Portability and Installation
Portable power stations are lightweight and easy to move. The BLUETTI Elite 100 mini weighs just 23.6 lbs, making it perfect for camping or quick setup. Standby generators are permanently installed outside and require a licensed electrician, but they offer hands-off operation with automatic transfer switches.
Think about your living situation. Renters or those who want flexibility might prefer a portable unit, while homeowners seeking seamless backup should consider a standby system. For a deeper dive, read our guide on the best whole-house generator brands.
