Hi, I'm a newbie.
I've taken the travel hub apart and made a power-only cable.
It's OK, because I have another one. :-)

And I've also made a black-and-red cable on the picture to let my 15V laptop adapter connected to the iLiad.
On the last picture, the red cable and sky-blue one on the left are the plus power cable.
The bluish green one isolated on the right is the minus cable.
Another minus is the bottom-left golden plate.
But, you know, I don't know anything more because I didn't do the job my self. :-)
