The iVoler 75W USB Type C Charger with Power Delivery has problems charging the Google Chromebook Pixel (2015).
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 Chromebook Pixel (2015) requests 15 watts (5 volts @ 3 amps) of charging from the iVoler 75W USB Type C Charger with Power Delivery.
Unfortunately, there are constant resets in the USB Power Delivery negotiation and there is never any steady state current and voltage delivered to the Chromebook Pixel (2015) by the iVoler 75W USB Type C Charger with Power Delivery.
