If your power goes out, you are at risk of losing data on your computer. If you get a power surge, or, if the power to your Mac or PC drops, it can cause damage to your computer. A battery backup UPS such as the CyberPower CP1500AVRLCD from Amazon works will help you. The most important feature is that it has an AVR- which regulates the voltae coming in. I actually use this one in my office!
