I have a Motorola Flip Stand with charger that I use with the MAXX HD, as well as a Nexus 7. I plug either one in and set them in the stand. I know it is not a "dock', but it might work for you. It is a quality product or I would not even suggest it.
I would post a link, but not allowed to, I'm sure a quick search will find it for you on the Motorola site.
