    Looking at the User Manual at http://h10032.www1.hp.com/ctg/Manual/c03283813 doesn't help much. Page 21, Adobe Reader Page 31.

    Same with the manual at http://h10032.www1.hp.com/ctg/Manual/c03282148. Page 10, Adobe Page 18.

    usb 2.0 can dish out roughly 500mA, usb 3.0 dishes out roughly 900mA and if you have dedicated charging port, it might be even give 1400-1500ish mA.
