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.

    I was looking for something very basic to keep my phone/internet modem powered in the event of a power company interruption of service. This not only has plenty of outlets, it also provides surge protection.

    I was happy that the Geek Squad man was so helpful in first confirming to me that my old one was indeed "dead". Then he showed where I could find a new Battery Backup and advised me on which one would be good for my situation.

    I use this for my TV, cable box, PS3... everything is on surge and the cable box is on battery backup so nothing is interrupted during storms / quick outages. My older 350v died and CyberPower is replacing it.
