It is designed to charge twice as fast as Quick Charge 1.0 and to be 38 percent more efficient than Quick Charge 2.0. It offers a more granular range of voltages: 200mV increments, from 3.6V to 20V. However, only devices with Qualcomm® Snapdragon™ processors can charge at those faster speeds. More details, please visit: Qualcomm.com
