If you live in a region with frequent or unpredictable power outages, you probably should invest in an uninterruptible power supply, or UPS for short. Just as the name implies, these devices provide immediate battery backup to an electric device plugged into it. Use it for your laptop, cable modem and WiFi router. If you use a CPAP machine to sleep, a UPS is a valuable tool for that as well.

APC sells power and infrastructure services both large and small, so it’s no surprise its UPS tops our list. This unit offers five outlets with battery backup and surge protection; an additional two outlets offer just surge protection. A 5-foot-long power cord provides some versatility when deciding where to install the unit. One USB charger port – perfect for smartphones and other portable electronics – is also included.

Don’t sweat the small stuff
Tripp Lite combines many of the features you need while providing almost 12 minutes of half-load runtime (or 4.4 minutes of full load runtime). All eight outlets provide power backup and surge protection. The LCD screen displays voltage, battery capacity and the unit’s overall status. It has USB and serial ports to help automatically save computer files as well. As with any UPS, make sure it’s installed in a place that’s shaded and cool as batteries can build up heat with usage.
