Um, maybe I'm missing sumpt'n but if its plugged into a usb port from a phone, or tablet etc., that IS where it draws it's power from.

Apparently phones and tablets don't have enough juice to run it. Pc's and/or powered usb hubs work but not phones or tablets with maybe an expception or two
From the Schiit site
iPhones: you'll need iOS 7 or 8, the magic overpriced Apple cable and a power source (hub or battery, or, for full LOLs, Wyrd.) This is covered in the Guides/Getting Connected section of the site, with links to cables, hubs, etc.
Android: you'll need Android 4 or 5, software for 4, and a power source. As above, this is covered in the Guides/Getting Connected section of the site.
so separate power is needed
