Needs more space between 110V Recepticals

Seems Good, Needs more space between the 110V AC recepticals

By Fathertime on HP - Oct 7, 2012


Strengths: Attractive (for a UPS), notification, electronically advanced

It comes with software to monitor the UPS and most importantly shut down the PC in the event of an extended power outage.

It's also supposed to be more energy saving, as it powers-down unused devices to save electricity and money. There's four battery backed outlets, up from three in prior models, and...
