This is a technologically advanced power conditioner. It is firstly, a UPS (uninterruptible power supply), surge eliminator (its their proprietary patented technology) and power conditioner. There are six outlets on the back where four of them are UPS/surge protected and two of them battery/surge protected that are meant for components that needs to be properly shut down when the power is out. A USB outlet allows you to manage the unit, read power data on your computer with the required software (available from SurgeX). There is a video of how this XU115 is different and better than other UPS which SurgeX showed at the CEDIA show a few years back. Look it up to learn more about it. Just do a search “XU115” in Youtube.
Cosmetically, the unit looks good. Just minor scuff marks/scratches here and there. This unit and another two (also for sale) were previously used in a recording studio where the battery backup outlets were necessary to keep the recording components going when power is out (which apparently happens occasionally in this commercial building in NYC) and to manage the constant voltage swing in that building. Manual is available online. Unit will be shipped with the battery pack disconnected so they will need to be connected prior to use.
