Found: Cheap powered (or power if needed) USB hub for iPad.
I got a MPK mini mk2 and needed unpowered USB hub to make it work with my iPad. I got this usb hub from Amazon because it was small, cheap ($12), and had everything I needed for unpowered or powered either battery pack or USB PS. So far its worked great with my iPad both powered and unpowered on both my MPK and my Launchkey 61. Need to see how it lasts though it seems pretty well made.
Does not charge the iPad of course since you still need the CCK.
Oh, you can get it in colors too, i got red 
! This one is 2.0, the 3.0 version is $1 more.

Cool, added to my wish list. Although the one I currently have works just fine.
Amazon page does not list the self-powered specs. What capacity battery is in it?
No battery included, it just includes a power chord to a standard USB plug that will plug into any of the USB batteries out there or a USB power charger. I used the USB charger for my iPad and that worked fine. I don't have a USB battery yet.
Sorry my first post was confusing.
