I am using a universal power supply that has a power setting from 2 to 12 volts, and a switch to reverse the polarity (which in this case just reverses the forward and reverse on the shredder). The power supply claims to produce a max of 800 ma at 12 volts. it works fine with one sheet of thick copy paper at a time, two or more tend to jam.(because of the low voltage) Since this is well below the stated need for 15 volts dc and 1400 ma that ffelllowes says is necessary, I suspect any generic universal PS with at least 12 VDC and 1 amp output would be sufficient. Of course, one with 15 VDC and 1.4 amps would be perfect... Hope this helps! Ansd yes, I just used the shredder on my taxes. BEFORE i sent them! :)
