Qualcomm’s Quick Charge 3.0 technology 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 has revolutionalised charging speeds for compatible smartphones and tablets. As more and more latest smartphones and power banks become QC 3.0 compatible, users can expect to top-up their devices’ batteries from zero to 80% in as little as 30-35 minutes.
Some of the latest smartphones supporting Quick charge Galaxy S9, S8, S7, Note 8, S6, and S6 Edge, Edge Plus, and Note 5, LG V30, LG V20, G6, G5, ZTE Axon M, Axon & Max, Blade Z Max, Moto Z2, Z, G4, G5, HTC U11 series, HTC 10, One A9, Sony XZ, XZ1, and Nokia 8 etc.
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.
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.
