Buying Guide: Planning for 2027

Keep these points in mind before you buy.

What to look for next year

LiFePO4 cells, fast UPS switchover, solar input and expandable capacity are the features to prioritize for long-term backup.

LiFePO4 batteries last longer

Lithium iron phosphate (LiFePO4) batteries handle thousands of charge cycles, which suits backup gear you keep for years.

Recharge with solar

A folding solar panel lets you recharge a power station during long outages. Output depends on sun angle and weather.

Generators belong outside

CDC says to run generators outdoors, more than 20 feet from windows, doors and vents, and never in a home or garage. Use a battery-powered CO detector.

Start-of-Year Checklist
