No worries. It's a 13 port Mbeat powered hub from Australia. It's one of the "Pi certified hub" from the Pi site. Hope this helps. Btw, it doesn't have enough juice to power the Pi on its own together with 10 erupters. Had to power up the Pi separately.
So they don't sell a US version of these do they? but it powers 10 of them without any issue?
As far as I know, they are only found in Australia.
If they are plugged to the computer, there's no issue plugging 10 erupters plus a fan.
For the Pi, I would think 8-9 erupters should work for each hub.
