What is QC 3.0?
QC 3.0 is a charging protocol ,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.
The advantage of 3.0 is that it can provide optimal voltage at the precise need of the battery, so during charging you are always at the fastest charging voltage.
2.0 jumps in stages, less efficient but still enhances speed.
