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.

    Great, but pay a bit more for the 850VA or more

    I recently bought the 850 VA, but wanted to try this one out, because the previous one was 650VA. I would pay a little bit more and get the 850VA because it has a bit more ports and it is more potent. This one is not bad, but I feel like replacing the 650VA was just like adding a patch to a flat tire, instead of actually getting a brand new tire; does the job, but nothing special. I recommend if the other ones are too pricy.

    The plugs are spaced out a bit but I still can only fit two of the big boxy type plugs in (one on each end). I wish they would have some vertical and some horizontal

    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!
