zdyCGTimeUSB 3.0 Female to USB 3.0 and USB 2.0 Male Extension Cable Data Splitter Y Extension Cable (13")

Can this device allow me to use my keyboard on pc and xbox at the same time?

If this is plugged into 2 x 5w (5v/1A) chargers to deliver power via a usb-to-lightning cable, how much power will the lightning cable deliver?

is there an indicator of which side you should use to suplement the power?

Could i use this to hear audio in my usb headset through my pc and ps4?
