Buying Guide: Backup Power Trends

Keep these points in mind before you buy.

Newer stations use LFP batteries rated for thousands of cycles, recharge in about an hour and switch over in 10 to 20 ms.

Add up the watts you need and the hours you need them; a 1,024Wh station runs a 100W load for roughly 8 to 9 hours after inverter losses.

Generators belong outside

CDC says to run a generator outdoors more than 20 feet from windows, doors and vents, and to use a battery-powered or battery backup CO detector inside.
