1. Introduction of Quick Charge 2.0 technology The so-called QC2.0 technology is actually a fast charging solution for mobile phones that combines the Qualcomm Snapdragon 800 series chipset. It will be based on Quick Charge 2.0 or QC2.0 protocol and can adaptively output 5V and 9V. Or 12V wall charger to quickly charge mobile devices such as mobile phones that support the Quick Charge 2.0 protocol. The working principle of QC2.0 fast charging technology is to increase the output voltage under the condition of the charging current limit, which further increases the charging power and greatly reduces the charging time. And divided into two industry standards A and B. A standard: 5V , 9V and 12V output voltage, B standard: 5V , 9V , 12V and 20V output voltage. two,
Introduction of Quick Charge 3.0 technology After the rapid charge technology Quick Charge 2.0 became popular, Qualcomm announced the launch of its next-generation fast charging technology Qualcomm-Quick Charge 3.0 . As the third generation of fast charging technology, Quick Charge 3.0 uses Intelligent Negotiation for Optimum Voltage ( INOV ) algorithm in 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 good power transmission at any time and maximize efficiency. Quick Charge 3.0 for the first time a " good voltage intelligent negotiation " (Intelligent Negotiation for Optimum Voltage , Inov) algorithm, can achieve good power transfer at any time and maximize efficiency. Quick Charge 3.0 can charge an ordinary mobile phone from zero battery to 80% in about 35 minutes without Quick Charge
The traditional mobile terminal usually takes about one and a half hours. Compared with the previous generation, by means of INOV and other advanced technologies Quick Charge 3.0 , may be achieved than Quick Charge 2.0 up to 38% to enhance the efficiency, but also other methods to help conserve battery life cycle. 3. Product range applicable to QC3.0 certification / QC2.0 certification Products that provide energy (in-line chargers, car chargers, mobile power supplies, etc.), terminal products such as mobile phones, tablets, and notebooks are not within its scope.

Certified products can be purchased in bulk from Qualcomm Quick Charge ICs , and the charging efficiency is increased by 40% -75% ; 2. The use of QC3.0 LOGO is allowed to enhance the corporate brand Influence and competitiveness; 3. Under the global environment that has been calling for energy saving and emission reduction, such companies and products will be more recognized by society and consumers.
