I'm trying to do something similar with a couple of electric toothbrush charges and an iPod cable coiled to make the secondary winding, but even with two primary windings I don't think it will work. I don't think I'll be able to induce enough current for it to be feasible.
It's great to see that you've got it working - this at least tells me what I'm trying to do is possible.
@bnwag Have a look at your toothbrush charger and read the specs about the input/output current... generally the iPod will not charge under 500mA, Also, to get the basics right, use a multimeter between your coils to see if there is even 5V being delivered. the iPod has a weird data pin voltage of 2v and 2.8v in order to allow a charge also. The Power supply i used was outputting about 1-1.5A to charge the iPod which was only a few cm away. ... some points to consider in your own design @bnwag
