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 purchased this to back up my router and modem. Sometimes we get brief power outages. My business computers are laptops and tablets. They all have batteries when the power isn't on. My modem and router shut off and the whole system has to re-boot. This backup gives me no down time and work keeps going! Great item if you only need minutes, upgrade to much larger unit if you need Hours.
