I just love this type of line - "connect another 9 LED's and the current draw is still 27mA"
(in fact, if you are around Manchester from your accent Jonny and if I don't get my immigration sorted, i'll buy ya a pint no problem !)
Yep totoalas, should be no problems with charging cellphones. My setup right now is only producing about 100mA, but it's only on a 1.5V battery. I'll try it soon on the big rig with the 2SC2625 and see how things go. All in all for a solution, it'd probably need a a 7805 voltage regulator (or LM317 or similar). Original chargers put out about 300-500mAh at between 3.7V and 5.5V, so it's not far distant.
Looking forward to your vid Jim...I may be completely wrong, but if your field is only a couple of inches at best, then it ought to be electromagnetic induction, coil to coil. If so, the wire size on the receive seems to have no affect, diameter is not really an issue, coils need to be orientated approximately level with each other else the field drops right off quickly. We're used to a size of wire for a size of job. But, in the wireless helicopter video on my YouTube thing, the heli is pulling all that power through a 12 wind coil of gauge 40 or similar wire and the bridge rectifier is simply signal diodes !
