Buying Guide: Budget Backup Power
Keep these points in mind before you buy.
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.
LiFePO4 batteries last longer
Lithium iron phosphate (LiFePO4) batteries handle thousands of charge cycles, which suits backup gear you keep for years.
UPS switchover
A UPS or UPS mode switches to battery in milliseconds so a router or computer does not reboot when the power blinks.
Budget Outage Tips
Make it last:
- Run only essentials.
- Use eco modes.
- Recharge when you can.
- Keep spares charged.
