yes, the computer provides 500 mah to the usb port so that would take 3.4 hours to charge the 1700 mah icon battery, but the ac adaptor provides i think 2 amps burst but 1 amp on average so it takes about 1.7 hours to charge.

What I remember from the documentation is that it will take much longer to charge from the USB port as opposed to the AC charger. I think there was a 1 to 4 diffence.
