Multi‐unit USB power delivery chargers allow multiple notebooks/devices to charge simultaneously from
a single charging station through USB power delivery over USB Type‐C ports. Such chargers are powered
from a fixed capacity power supply and are responsible for charging multiple units of varying power
requirements. The technique described below enables the multi‐unit charger to regulate charging
capabilities of different ports and implement a scheme that allows maximum number of notebooks to
charge in a given time with a fixed power supply.
