What is QC 3.0?
QC 3.0 is a charging protocol designed by Qualcomm
What’s qc 3.0? QC 3.0 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?
QC3.0 is all about how the power delivery to your device, and less about the actual strength of the power.
The feature of QC2.0 is stepped and violent, while the QC3.0 is natural and smooth.
- QC 2.0 have fixed multivoltage, 5, 9, 12 and 20V. This fixed voltage means, the charging is 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.
In the graph above (assuming charging current keep in identical); you can see the differences in the three charging technologies voltage output.
- 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.
- Standard fast charge stays at 5V and provides a slower charge.
This is the main difference of QC3.0. Or simply;
QC3.0 is smarter: The variable voltages delivers faster charge with the same power.
Here is a video to show how fast they works, when traditionally, you will need at least 5 hours to charge a 10,000mAh power bank from 0 to 100%. But with the QC3.0, only 2 hours is sufficient!
When compared to Quick Charge 2.0; the power output is only slightly more, however, the efficiency it delivers is increased so you experience a faster charge.
From your Samsung to your iPhone our whole range of QC fast chargers will minimize your time tethered to the cord.
