Charge the ipad with DJ Connect

I have just received a DJ Connect. I wonder how can I charge the Ipad meanwhile I have connected the device. Is there some splitter or so?

I’m sorry, Manolo, but as the iPad has only one port, charging the iPad while having it connected to the Griffin DJ Connect is not possible.

How Long does the ipad last when fully charged connecting to the DJ connect and running dJay app?
