When I swapped to a backup Apple wall charger, it wouldn't charge either. Both of these chargers are known good (I used them Saturday at home), so I'm not sure what was going on.
Next time I'm on a 763 I'll take a lower-power device and see if I can USB-charge it.
Those Apple products have built-in condescension mode that won't allow them to work with regular voltage. It needs to be ivoltage, from an iplug, on an iplane. Anything non "i" would be insulting and beneath the level of engineering.
