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.

    Works just fine as a surge protector; worked once as backup when the power went off, but now does not provide any battery power during an outage. Expensive for a one-time solution.

      Hello, That behavior is not expected of the SL750U. This UPS should recharge its battery with utility power each time. Please reach out to our support team at 877-297-6937 and we'd be happy to assist. We hope to hear from you! CyberPower
