Customers are saying

Customers are positive about the 450VA Battery Back-Up System's long battery life, surge protection, and performance. Many also appreciate its affordable price, ease of use, and compact size, with several noting the convenient number of outlets. A small number of users mentioned a noticeable humming sound when the unit is running on battery power, and the lack of a USB connection was also cited as a drawback by a few customers.

    No, it doesn't talk to computers or have bells and whistles. All it does is provide reliable back-up power. It's especially suited for bridging short outages and absorbing short time, but serious, surges.

    I have been a strict APC user for years but their customer service has been increasingly difficult to work with. They also do not stand behind their warranty like they did 15 years ago. CyberPower has been great to work with and the quality if their products have improved much over the years. I now purchase their products exclusively.

    It is peace of mind knowing that if I am working on something on my computer that I have time to save it and turn the computer off if we lose electricity. Also the surge protector gives added peace.

    Been thinking of getting one of these for a while now just in case power goes out we still have some battery power somewhere in the house. Works great and for a good price can't complain about it.

    We needed a good surge protector because we had several different items, including our telephone. It has plenty of outlets. It fits unobtrusively behind our television. A good buy and a good value.
