Why is Quick Charge 3.0 so fast?

What is QC 3.0?

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.

Why is QC 3.0 better than 2.0?

QC 3 compared to QC 2 is not a big jump, the power output is almost the same, the 8% gain is from increased charging efficiency.

It’s all about how the Adapter Charger is delivered to your device and less about the actual strength of the adapter charger; 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.
