• BB should have a universal supply that will work, but if you can also buy one to match these specifications on line. It is a 12V, 1.5 A Center Positive. Look for something like a 12 volt, 18W or 24W power supply for WD External Drives like My Book.

• if the plug fits, it should supply 12 volts DC, no less than 1.5amps, and should have the center be positive.
