The stand is meant for use with a case as it is slightly wider and has the charge hole slightly forward to accommodate the thickness of the case. I use a Spigen Thin Fit case but may work with others.
Two versions, one has a slot that fits the cable that comes in the Pixel 8 box. The other fits a one plus charging cable and a random cable I found in my drawer.
The clip clamps the cable in place but isn't really necessary as the fit around the cables is tight enough. I used pliers to push the cable through the hole.
