You won't find any single drive enclosures with bus power and two TB ports, simple.
 
I am not looking for power out the second port.

Still doesn't matter - no-one is going to make one. If you're looking to put a display or other thunderbolt device on the end of a drive enclosure, it will have to be a dual-drive unit like the OWC Mercury Elite Pro Dual or the Akitio Thunder2 Duo Pro, for example.

Which are hardly mobile. There IS a market.
