To see if you can quick charge your Nubia Z17 phone using the Targus 45W USB Type-C Laptop AC Wall Charger, we'll observe how the charger sets up a USB Power Delivery contract with the Nubia Z17 which also supports USB Power Delivery charging.

The Targus 45W USB Type-C Laptop AC Wall Charger starts off negotiation over USB Power Delivery by constantly advertising its source capabilities of 15 watts (5 volts @ 3 amps), 36 watts (12 volts @ 3 amps), and 37.5 watts (15 volts @ 2.5 amps) when directly connected to the Nubia Z17 over USB Type-C.

The Nubia Z17 at 1% battery later requests to pull 15 watts (5 volts @ 3 amps) from the charger which it accepts.

The Nubia Z17 is then seen to establish 36 watts (12 volts @ 3 amps) USB Power Delivery power contract with the Targus charger.

When the Nubia Z17's battery is 1% charged, the phone first draws around 12 watts (5 volts @ 2.4 amps) but later pulls about 3 amps @5 volts from the charger after 42 seconds.

After another 10 seconds, the phone draws around 18 watts (12 volts @ 1.5 amps) from the charger. However 30 seconds later, the current pulled goes down to 0.5 amps but increases after 20 seconds to charge at about 12 watts (12 volts @1 amps).  

The Targus 45W USB Type-C Laptop AC Wall Charger can be used to charge the Nubia Z17 over USB Power Delivery.
