I'm told an alternative is the Apple Lightning to USB 3 Camera Adapter.
Using this Apple adapter, one can connect their iRig device using the USB port while connecting their Apple iPhone/iPad charger to the available lightning port on the adapter. This will charge your iOS device during use while allowing the interface connection as well.
If that doesn't work or isn't the right solution, I'd suggest speaking about it further with IK Support via
