Buying Guide: Home Backup Power
Keep these points in mind before you buy.
Power bank, UPS, station or generator
Power banks charge phones; a UPS bridges short blinks for computers; power stations run devices for hours; gas generators run longer but must stay outdoors.
Size it in watt-hours
Divide a battery’s watt-hours by your device’s watts, then take off about 15% for conversion losses to estimate runtime.
Running vs. surge watts
Fridges and pumps need a short surge to start. Check both running and surge ratings against your appliances.
UPS switchover
A UPS or UPS mode switches to battery in milliseconds so a router or computer does not reboot when the power blinks.
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.
Medical devices first
If you rely on a CPAP, oxygen or other powered equipment, plan backup power with your doctor and utility, and check runtime before an outage.
Outage Readiness Tips
Be ready before it fails:
- List must-run devices.
- Charge every few months.
- Test once a season.
- Keep a CO alarm.
