QC3.0 charger adopts Intelligent Negotiation for Optimum Voltage (INOV) algorithm for the first time among similar products. INOV is a new algorithm developed by Qualcomm Technologies, designed to help portable devices have the ability to select the required power level to achieve the best power transmission at any time and maximize efficiency.

With the help of INOV and other advanced technology QC3.0 chargers, the efficiency can be increased by up to 38% compared to QC2.0 chargers, while other methods are also used to help protect the battery life cycle.
QC3.0 charger can achieve: Compared with QC2.0 charger, it helps to increase the fast charging speed by up to 27%, or reduce the power loss by up to 45%; the charging speed is 2 times faster than Quick Charge 1.0.
QC3.0 charger also brings many improvements: on the basis of QC2.0 charger, it has enhanced flexibility, especially in terms of charging options. The QC2.0 charger provides three charging voltages of 5V, 9V, and 12V, while the QC3.0 charger has a 200mV increment as one step, providing a flexible choice from 3.6V to 20V. This will allow the phone to get the right voltage and reach the expected charging current, thereby minimizing power loss, increasing charging efficiency and improving thermal performance.
The QC3.0 charger can be forward and backward compatible with the previous version of Quick Charge and connectors (including USB Type-C), and has the same ultra-fast charging speed and independent circuit, providing OEM manufacturers with more flexible choices.
