Product Reviews
Rated 4.5 out of 5 by 8reviewers.
Rated 4 out of 5 by We have a number of the 3S 750's we use for our personal desktops and peripherals, and they have been working well for the last year. They are not as huge and bulky as some other units and fit well under our workstations. So far I have no complaints! We haven't had any outages yet, so I suppose we shall test their mettle when the time comes. June 18, 2015
Rated 5 out of 5 by I put one of these on a home theater system and it's held up quite well. I've made sure not to overload the power on it. Between CyberPower and Eaton, I chose this model and quite happy with the result. Clean energy to my system. June 11, 2015
Rated 5 out of 5 by Does Eaton make a bad product? Really, do they make a bad product? This UPS is awesome, all the way up to their enterprise equipment. June 9, 2015
Rated 5 out of 5 by With a USB connection and the temps running low on this device, it's definitely the best standard desktop UPS around. My wife uses one, at my suggestion, and after going through a half dozen previous, this is the one she likes and trusts when there's a thunderstorm or snow. The only drawback is the incessant beeping when the line power is out. September 15, 2014
Rated 5 out of 5 by I've got one of these in the living room, with a lamp (LED bulb) on the battery port. The first time we lost power for a few hours, we had light. Couldn't believe how long this thing held up. After that I bought more for the house, and then looked into and bought larger ones for work. Quality build, great support (for the two times I had to call in the last couple years). September 12, 2014
Rated 5 out of 5 by I have one of these at home, and it works completely as advertised. Nothing extra special, other than it is from Eaton, a name I trust (I have since moved away from APC to Eaton over the years). Kept my system running during a short power blip the other day - which was a good thing, too, I was working on a document that I hadn't saved yet! September 12, 2014
Rated 2 out of 5 by The 700VA model saves up to 30% energy through its EcoControl function which automatically disables peripherals when the master device, such as a computer,is turned off. The shutdown software makes it possible to automatically save your work and shut down your application without losing any data. Once the power is restored, you can continue working exactly where you left off. March 20, 2014
Rated 5 out of 5 by I just got one of these as a replacement for a similar spec APC unit that failed. I have been using Eaton UPS units for all of my UPS replacements, as the whole UPS only cost a little more than new batteries for the APC and offer excellent service. November 11, 2013
