Let me add: Usually you will find a white strip running along one edge, or when you cut the connector off the end and strip back some of the insulation, you may find one copper and one silver colored (tinned copper, not silver wire). If all the adapters you are going to place in series are identical units manufacturer/ model number/voltage and current ratings, you can depend on the markings being uniform, and connect black lead to white striped lead, copper colored lead to tinned lead, and have faith they are wired correctly, without having to use a voltmeter to measure the output. If mixing different units, all bets are off and you'll need the voltmeter. As long as both your wires in the solution are silver, it won't matter if you know which lead is positive and which is negative, but if you are using only one silver lead, and stainless or other metal for the other electrode, then you must know with certainly which lead is which polarity.
It doesn't matter the current rating of the wall wart - maybe it's 50 mA (milliampres), maybe 100, 400, 750, 1.4 Ampres, whatever, because current flow is controlled by the applied voltage and the resistance, as expressed by ohms law, E=IR or I=E/R. The CS making process will start with a very high resistance and only a small number of microampres will flow at first. Only a few mA will be flowing at the end of the process, within the capabilities of any wall wart. Note also that the voltage marked on the case is the voltage that will be output when the marked current is drawn. When very low currents are drawn, the output voltage will be much higher than marked, as much as 50% higher for cheaply made wall warts. Thus with a voltmeter, you might find that two 9 V units was giving close to the 27 V you would expect from three 9V batteries. If using three 9V wall warts, the voltage will be higher than 27 V, and your brewing time will be less than with batteries. As has been mentioned before, but can't be repeated too many times, the wall warts MUST be DC output units, not AC.
