I'm thinking specifically of needing to power my MIDI keyboards or my iPad.
The MRCC USB host ports provide USB 2.0 power. That's 500mA per port so it should power any USB 1.1 or 2.0 MIDI controllers. We've not seen any MIDI controllers that it won't power because none of them use anything but MIDI 1.1 or 2.0. Maybe more power hungry controllers are self powered.
On the other hand, it probably won't keep your iPad charged. The iPad will need to connect to the MRCC PC port (USB A to USB B). For my iPad I use a lightning dongle which has a USB A socket and a lightning pass-thru so I can connect the USB A to B cable to the MRCC PC port, and use the lighting port to charge it.
