Is there anyone here who knows technical specifications on the magnetic connector on the Surface devices from Pro 3 and up. This connector appears to be a very powerful I / O, but I have never heard any specifications on it. Furthermore, I find it strange that there are no 3-part equipment that makes use of it. If this is universal, it should be possible to connect a Surface Pro 3/4 to the keyboard of an Surface Book if you could make the connection. Also a portable hub with I / O that does not need, but can make use of, external power supply, could this be possible? Has the feeling that this connector has an unexplored and untapped potential. What if the phone got the same connector? Could you have docked it in the Performance Base for Surface Book? Or a dock for Continuum support? That last one would realy open a window to try using Continuum full time.
