The Tek Republic hub would appear to be an Action Star UH-217C-US. The power adapter shown in the Amazon photos is the same included with mine (Sunny branded, 5V 2.6A).

Personally, I am mining with my 6 BEs + fan on an ancient (~14 years old) Newer Technology 7-port USB 1.0 hub w/ some random 5V 4A power adapter.
