Qualcomm’s Quick Charge 4 charging technology was introduced back in November 2016. It is the first to be compatible with the USB PD2.0 protocol, and has eliminated the 12V charging and boosted the power to 28W. The standard 5V can output 5.6A max, and 9V can output 3A. With the announcement of the USB PD3.0 (PPS) charging standard, Qualcomm QC4 also ushered in an upgrade and evolved into the QC4+ charging standard which is compatible with USB PD3.0 (PPS), QC3.0, and QC2.0.
