One thing to add to the notes...
The original cable that came with the iPad 1 has a short strain relief on it.
The cable that came with the new iPad 3 has a longer strain relief and need to verify but is thinner in diameter.
The iDevice can detect how much it can pull to recharge by the voltage level on the data pins of the USB.
