Although I don't have an ultraportable laptop with USB C PD, I have many batteries that charge USB C PD with 30 60 even 100W input power. These powerhouses allow me to charge my batteries much faster than normal "phone chargers" allow (typically 12-18 watts), if your device can handle 65 watts it will deliver.
