I'm considering getting the MP3 USB integration device from the RPM store.

My concern is that it does not have enough power to feed a portable hard drive which is what I would like to do.

So my question is where can I get the 5 volts needed for the hard drive and how can I make sure that the voltage is stable, do I need a voltage stabilizer and if so where can I get one.

Thanks in advance for your help.
