    I bought this UPS to protect my computer, monitor and wireless router from power surges and temporary power outages. It has done the job a couple of times and has plenty of power to keep everything running throughout these outages.

    CyberPower - 450VA Battery Back-Up System is a very easy to set up silent backup system, for you light duty electronic equipment. Can keep you cable modem, computer network switch and home phone system running during those short brown outs or black outs. Super easy to use, just plug it into a wall socket, then plug in the needed equipment.

    Especially with monsoon season and lightning storms, I don't have to worry about electrical spikes. It protects all equipment and if power goes out - or a brown out - it has up to 1/2 hour of battery so you can shut down safely!

    I purchased this device for not only for the battery backup but also for the phone line surge protection. I was concerned it would interfere with my DSL connection but had to have something to protect my modem due to past experiences with frequent storms here. Running my phone line through the protector however I have not had any noticeable increase in line errors. I was also concerned because it seemed to too light to be housing a battery sufficient to power devices for the advertised rate. Although I have not extensively tested it I have not had any device connected to it reload due to power outages I have had.
