With build in QC3.0 fast charge, our latest Fast charging module can reach 140W. You are wondering HOW FAST IS QC3.0, AS COMPARED TO OLDER GENERATIONS OF QC2.0? 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. As you could see from the above picture, in terms of power output, QC 3.0 is not much different from QC 2.0 to be frank, however, they are not the same in these ways;
1.QC 2.0 multi-voltage is fixed at 5, 9, 12 and 20V. This fixed voltage means the charging is done in voltage stages.
2.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.QC 2.0 jumps in stages, less efficient but still enhances speed.
4.Standard fast charge stays at 5V and provides a slower charge.
The advantage ofQC 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. Simply, we can put it this way;
Conclusion is that QC 3.0 is smarter.
Starting from 2010 as a fast charging PCBA module manufacturer, APS has sustained extensive growth over 12 years.
