The Choetech PD72-1C3U 72W 4-Port USB Type-C PD Wall Charger enables 60W based charging from its USB Type-C port using USB Power Delivery 2.0 technology. Even though the Choetech charger is USB-IF certified, we observe Qualcomm Quick Charge negotiation when charging the Xiaomi Mi 5 phone which only supports Qualcomm Quick Charge 3.0 technology and not USB Power Delivery.
Using a USB Type-C to Type-C cable, we connected the Mi 5 to the Type-C port of the Choetech charger and observed charging. After more than 10 seconds from initial plugin only we could see the phone began pulling current while the voltage started up at 5 volts. As the voltage later rose up to a 9 volts rail, the current settled out for charging to happen at around 5.4 watts (9 volts @ 0.6 amps). Get more details here by downloading the trace captured by the GRL-A1 power analyzer. Note that this charger negotiated to 9 volts while the Choetech PD32-1C1U 32W Dual Port USB Type-C PD Wall Charger actually went back to 5 volts (see this review).
With only 5.4 watts, expect charging to be very slow although the Choetech PD72-1C3U 72W 4-Port USB Type-C PD Wall Charger is still able to charge the Mi 5 which means the charger can also support Qualcomm Quick Charge 3.0. However the Xiaomi phone can get up to 12 watts to charge much faster with its own Qualcomm Quick Charge 3.0 charger that shipped with the phone.
