IOS Mobile Djing world needs a cable that can connect USB controllers/audio cards to iOS devices while bringing full power to them.
Currently there are some mixers that offer a built-in solution with a lighting connector but they’re usually overpriced. Other very good mixers need much more power that what’s provided by a standard lighting port. So the usual trick is to connect these through a powered USB-Hub which brings complexity and points of failure to the setup.
The idea would be to have a lighting to usb-host cable that also has an AC power input built-in that you’ll optionally connect to a 5V wall adapter such as those that power some usb hubs.
One would agree to pay a $20-$25 for such a useful accessory.
