I use Anker USB bricks that can power 5 Cubieboards.  I am not family 
with a similar 12v alternative.  I do have some 12v hubs that I power 
with one 12v power supply and a 3 branch power cable, as the hubs pull 
so much less power than the power supply they shipped with can supply.

5v is just so much a part of our environment now, that 12v cannot meet.
