While working on 2 screens at the same time, connect your phone with usb C connection to the adapter to charge it. When you go to location, the phone is charged. You put the adapter in your bag and take it with you. The aluminum housing can take a beating and is not damaged while you travel. Note: DP Alt Mode is required on the linked screen.
