Battery backups can save your butt during a blackout, but they're usually pretty pricey. Best Buy has one on sale for $29.99.

One of the nice things about using a notebook is that if there's a sudden power outage, you won't instantly lose your work. Desktop users aren't so lucky, which is why it's essential to plug everything into a battery backup (aka uninterruptible power supply). If the lights go out, you'll still have a few minutes in which to save your work and power down the machine safely.

Best Buy has a CyberPower battery backup on sale for $29.99. It includes six wide-spaced outlets, all of them surge-protected and three of them powered by the battery. The 240-watt backup promises between 8 and 20 minutes of runtime, depending on the power demands of your hardware. It also has a pair of phone/fax/modem ports to keep that gear from getting fried. CyberPower even backs your equipment with a $35,000 warranty. Battery backups can cost a pretty penny; here's your chance to get one on the cheap.
