The battery capacity of smart phones is getting larger and larger. In addition to power saving, charging speed has become a feature that users are paying more and more attention to. Quick Charge technology has become one of the models in the industry. Following the Quick Charge 2.0 specification, the latest QC3.0 charger technology (referred to as QC3.0 charger), the general mobile phone only needs to be charged for about 35 minutes, the power can be reduced from 0 % Increased to 80%; while traditional mobile devices that do not use Quick Charge technology, it may take about 1.5 hours.

QC3.0 is backward compatible with the previous Quick Charge version, and can support the latest USB Type-C connector; it is more flexible in charging options, QC2.0 provides 5V / 9V / 12V / 20V four voltage options , And the QC3.0 charger provides a flexible choice of different voltages within the voltage range of 3.6V to 20V in increments of every 200mV. QC3.0 charger allows mobile phones to select the most suitable voltage to achieve the ideal charging current, thereby minimizing power loss, improving charging efficiency and improving thermal performance.
