Thanks for that. I may use this idea if nothing else pans out. The challenge is that I may not be able to bring the adapter closer due to physical constraints.
With this in mind, I am suspecting that the data connection is somehow telling the iPad to accept the charge (like a digital sensor). Would it be able to fool the iPad that it's getting its charge from a 'approved' charger, yet provide the actual power from the 5Amp power supply?
