    There is nothing not to like about this UPS. It fits perfectly in my network rack cabinet to keep my PoE cameras powered during power outages. It is slim enough to take minimum space yet provides enough power to keep the PoE devices going long enough to safely shutdown or ride out the short power outages.

    Needed a good battery back-up. Now understand it has been awhile since I have purchased one of these. I was startled at how inexpensive it was. Very pleased with the product and its price,

    I am a science teacher and have a desperate need for reliable power. This UPS has already paid for itself when, during a lab project, the electricity went out for over 30 minutes and I was able to complete the project for my students without any difficulty. What a great investment!!

    This is a great UPS. We don't have power failures here very often BUT we do have "dropouts" when high winds short out the grid for a few seconds. I have computer, monitor, modem, and router on this device...never have lost anything.

    Works great, save me while I was working and power went out. Gave me time to save my work and shut everything down. Also let me charge my phone while power was out. I would say i would have about 15 min of pull desktop and monitor time with the battery back up.

    I took this unit home, set it up, and 4 days later had a power outage! The CyberPower Back-up system kicked in and kept things running for over 45 minutes until the power came back on.

    Narrow design battery backup

    The narrow design of this battery backup is what sold me. Easily sits behind the entertainment system. Makes it easier to conseil unit. Wish the spacing of the four plugs were a little bit further apart.
