 You're going to need some sort of voltage regulation to drop that 19V
down to a level most equipment wants. The input of the R-Pi is 5V (as are
the BeagleBone Black, Arduinos, TIVAs, etc.). Going much above those levels
will either damage the board, or cause very hot running if they have
on-board regulation.

 I suspect most "full size" drives are either 12V or 5V (probably
depending upon connector). A "Best Buy" drive enclosure I have uses 12V@2A
wall wart barrel jack and a USB-3 connector for data (not power).
