    CyberPower - 850VA Ecologic Battery Back-Up System

    TOO MANY T-STORMS have caused too much damage to other places. My UPS died because of old age. Bought this as a replacement and it is GREAT. So surges get thru and don't lose power when the house does. I have a generator that kicks in but this keeps it going thru the downtime.

    I needed a wall mount UPS for a small closet. Used APC before but that model has been discontinued so had to look for alternatives. This UPS fit perfectly with 4 holes on the bottom to hook screws in wall. I'm using the unit to protect wireless AP switch in the area.

    Excellent basic UPS for home network

    This is an excellent UPS for a home network. I bought it to replace an older Cyberpower UPS with a failed battery. Provides plenty of backup time for the essential parts: CPU, router, monitor, plus surge protection for the non-essentials such as printer/scanner. Plenty of outlets on the FRONT of the UPS, spaced in a pattern that accommodates those big power adapter plugs. I also like the ability to stand this UPS up, taking up smaller "footprint". Pretty good software to help manage the UPS. An added benefit is the ability to replace the worn-out battery in the UPS unit. after a little research, I was able to locate the specific battery used in my old UPS (also a Cyberpower), order it, and install the battery. Now I have a fully operational "spare" UPS, which I now use on the entertainment center.

    What a great find. This battery backup is for our computers, monitors, printers in our den. Couldn't have asked for a better product. Will always buy replacements from Best Buy.

    I have a bigger version of this on my PC, but when I bought a 70" TV, there was no question that I wanted to get a UPS ... Anndd in my opinion, I would rather purchase UPS as a physical "warranty" on my equipment versus paying for a "real" warranty that I will most likely forget about or not be able to use. Biggest risk to electronics? Dirty power ... Best way to protect against it? UPS ...

    Great outlet spacing for those stupidly shaped plug-in power supplies. 5 stars if it had USB charging ports.

    Great ups for the price. Haven't tested the battery function as we haven't had a surge or power outage yet but I anticipate it will do the job.

    I live in Fl. And we get a lot of power surge espcially during a storm. This product will help you keep the wifi running even during a black out. I use the battery for my modem router and security devices. Works great espcially the LCD multifunction screen so you will have an idea how much battery % left for the back up. This is much lighter in weight than the other 850VA without the screen

    We had a lot of brief power outages/brown outs over the holiday season. On top of that, our grid is not the most reliable even in the best of times. My computer was spontaneously shutting down right in the middle of using it for no apparent reason, so I thought I'd try a UPS. Bingo! No more spontaneous shut-downs. I like how the display can show current voltage. Very happy with this purchase.
