If you’re familiar with UPS systems—uninterruptible power supplies—you likely know they’re usually designed for devices with huge power consumption requirements, such as desktop computers or even servers. APC had a pretty brilliant alternative idea: why not offer an inexpensive option to keep laptops and tablets online when the power goes out by guaranteeing enough energy for your router and modem, which require a lot less juice? That’s what Back-UPS Connect ($50) is for. The compact, reasonably-priced system strikes us useful both at home and in the office.
APC’s three-outlet system promises to provide about three and a half hours of power to low-drain systems such as modems, routers, and VoIP phones. This should be enough to keep you going while working off of battery power on your MacBook, iPad, or iPhone. If you want, you could even charge those devices from the UPS, although that will definitely drain it faster.
