I bought the Juiced 10-port from Amazon and suggest getting something else.  It'll run 8 erupters but when you plug in a 9th it starts to lose contact with one, then another, then another and the only way to fix that is either restart cgminer or unplug/replug the miner.  The Anker's extra amp makes a big difference.

Adding insult to injury my Raspberry Pi can't see this hub at all, so I think I'm going to order the Anker from Amazon and return this one.
