The Qualcomm Quick Charge 4+ certified Razer 24W Charger was initially made to provide up to 24 watts charging for the Razer Phone. Since this charger also supports USB Power Delivery 3.0, we'll see how it charges the Xiaomi Mi 6 which is a USB Power Delivery 3.0 enabled phone.
After connecting the Razer 24W Charger to the Mi 6 with a fully discharged battery using a USB Type-C to Type-C cable, the phone initially kept on using Augmented PDO's to request the Razer charger to ramp up from 5 volts to 12 volts and later from 3 volts to 9 volts. In between, the phone was not really able to pull current from the charger and thus not able to properly charge. Once the battery has charged a bit, the power charging reset resulting in up to 17 watts of charging.
