Charge & Sync with Computer USB Port
When connected to the computer by the included
USB cable, the iPhone/iPod will sync with the
computer and charge at the same time. After the
iPhone/iPod is fully charged, the docking station
will start charging. When connected to the
computer by the included USB cable, the iPad
will sync with the computer but will not charge
(same as with Apple USB cable).
Note: When charging an iPhone/iPod with
the included USB cable, if the USB cable is
disconnected, the docking station's battery
will not charge the iPhone/iPod
automatically. You need to re-insert the
iPhone/iPod into the docking station.
