Due to different design logic of traditional and USB-C adapters, Innergie laptop adapters do not provide USB-C tip. The traditional adapter’s output power is fixed in 19.5V and USB-C adapters’ output power is auto-switch to 5V, 9V, 12V, 15V, or 20V upon laptop’s input request. If you would like to charge your USB-C laptop, please choose Innergie 65C Black or 65C White.
