How We Chose the Best Emergency Power Supply
To choose the best emergency power supply, we compared popular power stations, UPS units, generators and solar panels on Amazon by capacity, output, recharge speed, switchover time and owner feedback.
CDC says to run a generator outdoors more than 20 feet from windows, doors and vents, and to use a battery-powered CO detector; see the CDC carbon monoxide poisoning basics.
Product details in this guide are based on manufacturer specifications and verified owner feedback. Read more on our How We Test page.
Buying Guide: Choosing Emergency Power
Keep these points in mind before you buy.
Power station, UPS or generator
Power stations are quiet battery units you can use indoors; a UPS keeps a modem or PC running for minutes; gas generators run longer but must stay outdoors.
Size it in watt-hours
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.
Running vs. surge watts
Fridges and pumps draw a start-up surge; make sure the station’s output and surge ratings cover it.
UPS switchover
Some stations switch to battery in about 10 to 20 ms, which keeps many routers and PCs running; check the listing.
Solar recharging
Portable panels let you recharge during long outages; check the station’s solar input limit and connector.
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.
Outage Readiness Tips
Be ready before the storm:
- Keep stations charged.
- List your must-run devices.
- Run generators outdoors only.
- Test your setup twice a year.
