First, let me tell you the difference between QC3.0 and QC2.0.
QC3.0 is Qualcomm's new generation of fast charging technology, a black technology in the snapdragon 820 processor, 20% faster than QC2.0, the previous generation of fast charging .Relevant technical documents shows, the Quick Charge 3.0 can charge one mobile phone from power off to 80% battery volume in about 35 minutes. While traditional mobile terminal without Quick Charge function usually need about 1.5 hours to the same performance.
Compared with Quick Charge 2.0, QC3.0 will increase the fast charging speed up to 27%, or reduce the power loss by up to 45%. Its charging speed is 2 times faster than Quick Charge 1.0.
In terms of charging voltage, Quick Charge 2.0 provides 5V, 9V, 12V and 20V four grade charging voltages, and Quick Charge 3.0 is a flexible selection of voltage from 3.6V to 20V with the increment of 200mV. This will allow the phone to get the right voltage to reach the expected charging current, thus minimizing the loss of power, improving charging efficiency and improving thermal performance.
In addition, the Quick Charge 3.0 compatible previous version and charger (including USB Type - C) and have the same super fast charging speed, as well as the independent circuit. It provide a more flexible choice for OEM manufacturer, and help to achieve the quality and safety standards of UL certification.
The Digital demodulation Solution 10W 3 coils wireless FAST charger module can compatible QC2.0 and QC3.0. That means more convenient and efficient during use.
