The Sony Cybershot DSC-T200 comes with an external wall mounted charger for its proprietary battery. Some Sony cameras allow you to draw power from a computer's USB port. Is this possible with the DSC-T200?
According to Page 35 of the manual, the battery can only be charged in the charger, not in the camera.
(note: the linked manual says DSCT70.pdf in the link, but the manual covers 3 versions including the T200).
