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.

    Pretty good for what I use it for. I use it to power a cable modem only. It lasts for a while. I do not recommend putting much of a load on it. The battery is not good enough.

    It appears to work. I’ve plugged in a couple of devices and then unplugged the power source and it stays powered up. The true test is when there is a true power outage which I hope doesn’t happen.
