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.

    CyberPower Failed Me!

    I have purchased several CyberPower ups over the past several years with no problem. On 9/4/20, I purchased a Cyber Power 750VA battery back-up system. On 10/6/20, it failed - 32 days after I installed it! Since Best Buy's return policy is for 15 days only, I contacted CyberPower. Marvin was very helpful and sent the necessary documents to me to return the UPS back to CyberPower. I will receive a new replacement on 10/16/20. Several battery back-up systems that I have purchased from other companies have quit working after the warranty expired. However, this is the first CyberPower UPS to fail me.
