What Supply Voltages and Currents Does It Need?

I want to run an AirPort Express off a battery power supply. The cells I will use have a nominal voltage of 3.2V.

Could I run this with a 5.1V 1A source AND a source with virtually unlimited current and a voltage that fluctuates between 3.1V and 3.4V?

(By the way, those were two separate supplies mentioned, separated by AND. Not sure if that was obvious. Thanks to iFixit's power supply replacement instructions, I know that the AirPort Express requires two separate voltages.)

Rather than answering the above question, you could tell me exactly what two voltages it needs and the maximum currents it will draw at each. That might be easier :)
