APC Back-UPS ES 550VA Desktop UPS


This 120-volt, eight-outlet battery backup and uninterruptible power supply (UPS) provide emergency power through short and medium-length power outages. Battery backup features a 330-watt/550-VA output capacity. USB connection lets you use your PC to access additional power protection and management features. Disconnected battery notifier warns you when a battery is not available to provide backup power. Dataline surge protector guards your connected equipment from power surges on the data lines. Wiring fault LED indicator informs you of potentially dangerous wiring problems in the wall circuit. Plus, this battery backup protects electronics from surges and spikes without reducing the battery power that's used to run primary electronics during an outage.

    Great device. Please add mounting holes on the back so the UPS can be hung on the wall. The previous model had these mounting holes. We miss them.

    Reviewed at http://www.apc.com/

    I thing is as good as the two 500U's that I replaced with the 550's. All of the various Back-UPS's that I have I only have trouble withn the batteries going bad. They do the job that they are made for and that is all that I can ask for.

  • Great Workstation UPS
    Reviewed at http://www.apc.com/

    The UPS is perfect for workstations and other assorted equipment that require the ability to "ride through" a brief power outage. I use the exchange program and find the pricing along with the ability to easily recycle and receive credit for the older units to be an excellent solution for all consumers, both personal and business. I highly recommend these UPS units over any of the other brands.
