Great thunderstorm protection or voltage spikes. A momentary power outage can damage equipment when the AC comes back on almost instantly. With this UPS, the battery takes over while the AC is out, so devices never even know the power was off. We've used similar models for 5+ years on computer equipment, HDTV/DVR gear and more with no issues.
