Note:
1.Due to the Google pixel's official C-port wall charger and Google's private charging protocol, cellphones can only charge at a normal speed instead of a fast speed when you use USB C to A cable or the A-port wall charger. In order to achieve fast charging, you should use the Pixel original C-port wall charger and C to C cable. Apple iPad Pro 2018 (11 inches and 12.9 inches) may not get the full charging speed due to the same reason.
2.The maximum output current of this cable is 3A, so it cannot charge HUAWEI Mate 9 or OnePlus at full speed, because HUAWEI Supper Charge requires 4.5V/5A and One Plus Dash Charge requires 5V/4A.
