The iVoler 75W USB Type C Charger with Power Delivery can charge the Apple iPad Pro but not using the same 29 watts (14.8 volts @ 2 amps) that you get from fast charging with the Apple 29W USB-C Power Adapter.
Based on the protocol trace taken with software from Granite River Labs, at first glance the iVoler charger supports 15 watts (5 volts @ 3 amps), 27 watts (9 volts @ 3 amps), and 45 watts (15 volts @ 3 amps) power profiles. However, when you look deeper, the iVoler charger is issuing source capabilities that advertise different PDO's- one source capability advertises 3 PDO's (5, 9, 15 V) while another source capability advertises 4 PDO's (5, 9, 15, 20 V). Issuing source capabilities that advertise different PDO's violates USB Power Delivery Compliance.
The Apple iPad Pro needs 14.8 volts for charging quickly over USB Power Delivery but for some reason the iPad Pro only requests 12 watts (5 volts @ 2.4 amps) of charging from the iVoler 75W USB Type C Charger.
Note when the Apple iPad Pro is already well charged, it doesn't pull a lot of current from the iVoler 75W USB Type C Charger.
