Manufacturer Mini Powerful Dual USB Car charger Adapter Quick charge 3.0 Smart Port Car charger for Android Devices

QC 3.0 is a charging protocol designed by Qualcomm, it offers stepless multi-voltage charging from 3.7V to 20V; your device can receive the perfect voltage and current optimized to its exact charging state. Your device needs to support Quick Charge to receive any benefit.

It’s all about how the power is delivered to your device and less about the actual strength of the power; 2.0 Is stepped and violent, 3.0 is natural and smooth.

QC 2.0 multivoltage is fixed, 5, 9, 12 and 20V. This fixed voltage means the charging is done in voltage stages.
QC 3.0 can change exact voltage and can be anywhere between 3.7 and 20v, the charging is variable and this increases the overall efficiency of the charge.


3.0 vs 2.0 vs 1.0
Perhaps the best way to look at this is to compare the charging values between each of Qualcomm’s Quick Charge revisions.

  Quick Charge 3.0 Quick Charge 2.0 Quick Charge 1.0
Voltages 3.2v - 20v dynamic 5V / 9V/ 12V 5V
Max Power 18W 18W 10W
SoCs Snapdragon 820, 620, 618, 617, and 430 Snapdragon 200, 400, 410, 615, 800, 801, 805, 808 and 810 Snapdragon 600

Here we can see that the amount of current offered by Quick Charge has remained relatively consistent, but increasing the charging voltage has helped allow for faster charge times. With 3.0, the range of voltages will allow for fast charging and better efficiency.
