    CyberPower - 450VA Battery Back-Up System

    Works fine, but the outlets could be spaced farther apart to allow for the big plugs with built-in transformers.

    Read the description carefully; best used for modem backups but not for any modern equipment setup.

    Pictures are very misleading. No UPS port as shown

    I bought the unit to replace a 350va unit that I use for my NAS unit. if you look at the pictures of the CyberPowerPC 450va, you can CLEARLY see a UPS port. I know, I should have read the specs. My bad; I agree. But I was so excited to see a 450va (more than enough power for my needs) with a UPS port, I bought it. WRONG- This unit DOES NOT HAVE A UPS Port. No you cannot use it for adequate NAS protection.

    No, I would not recommend this to a friend

    It is a surge protector plus a UPS. Great for desktops as you can save whatever you were working on in case of power failure
