Customers are saying

Customers frequently mention the 750VA Battery Back-Up System's great size, reliable battery life, and overall performance. Users appreciate its ease of use, excellent value, space-saving design, and adequate surge protection with plenty of outlets. While some find the plug spacing a bit close and the unit somewhat heavy, the noise level is generally acceptable. Overall, the positive aspects of the product appear to outweigh the minor drawbacks.

    Got this to use for my cable modem, which I have to keep on the opposite side of my room to where my network stack is. No issues thus far, still haven’t gotten into storm season yet. Should be ok for light load power continuity

    perfect solution for my low voltage closet, now if i get a flicker or short power outage, i am not stuck waiting for everything to reconnect. especially if there are back to back brown outs! perfectly complements the whole house generator, so when we lose power, in the few seconds it take for the generator to kick on, we dont lose connectivity or have to wait 10 minutes!
