If you own a computer chances are you need a UPS. Why? Well when the power goes out it can result in data loss and hardware damage which can shorten equipment life expectancy. This battery backup unit provides sufficient emergency runtime power to allow for safe closure of open files and proper shut down of electronics when an outage occurs. The importance of this seems slim but can be a life saver and this is almost 50% off retail. So, I would get this while it last cause this deal is only on Newegg for today! Alternatively this is selling new on Amazon right now for 76.95.
