If you need to provide power to more (or larger) devices at your computer workstation during an outage, it can deliver up to 847 W-we had trouble finding home-office gear powerful enough to overload it in our testing. The APC BR1500MS2 is the most expensive UPS we recommend for most homes or small offices, but it offers a lot of value in the extra features it includes. Measured surge protection: 540.4 let-through volts.Measured run time with a 300 W (modem, router, PC, and hard drive) load: 17 minutes.Measured run time with a 20 W (modem and router) load: 4 hours.Five of its 10 outlets are backed up by a battery, and its compact shape-about the size of a three-ring binder-and its 6-foot cord make it relatively easy to stow under a desk or nightstand. It requires no setup aside from plugging it in, and it includes automatic voltage regulation-an important feature that some cheaper models lack. In our tests, it provided enough power to keep a household broadband modem and Wi-Fi router running for four hours, which means you can stay online while the power is off and get in touch with emergency services, follow news and weather changes, or just pass the time on your favorite websites. The CyberPower CP900AVR will cover the basics for most people during common, short-term blackouts.
