The difference between fast charging QC3.0 and QC2.0

Edit:Shenzhen Keliway Technology.,LtdUpDate:Aug 25, 2018

    Qualcomm QC2.0 fast charging technology can charge half of the battery of a mobile phone in 30 minutes, can support 5v, 9v and 12v voltage and 1-3A high power output, so many mobile phone manufacturers use this fast Charge technology, many car charger manufacturers have also applied this fast charge technology to car charger products, more and more consumers have realized the convenience brought by fast charge, get DD359uuQC2.0 dual USB fast charge Charge is such a car charger that uses fast charging technology, which greatly enhances the user's charging experience.

    QC3.0 (Quick Charge 3.0) fast charging technology claims to increase efficiency by 38% compared to QC2.0, fast charging speed up to 27%, and help protect battery life cycle Q. For the first time, C3.0 uses the "Intelligent Negotiation for Optimum Voltage" (INOV) algorithm to achieve optimal power transfer at any time with maximum power.

The difference between the two:

    Charging speed: QC2.0 can fill half of a mobile phone battery in 30 minutes, QC3.0 can charge a mobile phone from zero to 80% in about 35 minutes, which is why it is related to QC2.0. The charging efficiency is increased by 38%, and the charging speed is increased by up to 27%, which means that the power loss is reduced by up to 45%.

    Charging voltage: QC2.0 provides 5V, 9V, 12V and 20V four-speed charging voltage, QC3.0 is in 200mV increments, providing flexible options from 3.6V to 20V. This will allow the phone to get the right voltage to the desired charge current, minimizing power loss, improving charging efficiency and improving thermal performance.

    In addition, QC3.0 is compatible with QC fast-charge versions and chargers (including USB Type-C) forward and backward, and has the same ultra-fast charging speed, as well as independent circuits, providing OEMs with more flexibility. Choices, as well as UL certification to help meet quality and safety standards.
