The hub I'm using is Gaffa taped to the mount- difficult to see the model #, but it looks like one of these:

The DC-DC convertor is marked:
Auto DC Power regulated adaptor #A92JH
Input: 12V 3.2A
Output: 1.5/3/4.5/5/6/9/12V - 3A max
Looks similar to this but with 3.2A capacity....

Hope this helps.
