By simultaneously increasing the current and voltage to improve the speed of charging .

Qualcomm’s Quick Charge technology primary focus was to maximize phone charging transfer while being efficient. Quick Charge 2.0 allows for charging power levels of 36 watts in certain situations. Qualcomm split Quick Charge 2.0 into two classes to differentiate device, Class A and Class B. Class A applies to smartphones, tablets, and other small portable products while Class B caters to devices not used by the mass market.

Class A devices supporting Quick Charge 2.0 allow for a maximum charging current of 3 Amps depending on the source of the current. A typical smartphone charger runs at 5 volts and drawing about 3A of current. Theoretically, Quick Charge 2.0 can boost up to 15 watts of power from a 5 volt power supply which results in a faster charging time.

Class A devices have also been designed to work with 5, 9, and 12 volt power sources making them more compatible with a wider range of power sources. This means that a single charger will be able to cater to wide range of devices while delivering fast charging times. This also means that voltage loss from very long cables or a poor quality cable can be minimized as well.
