Its full name is "Quick Charge", and the abbreviation is "QC". Quick Charge, also known as QC, is a charging technology based on "a system on a chip" developed by Qualcomm, a US company. It enables the charging rate of supported input/output devices to surpass standard USB. There are three different versions of this technology: Quick Charge, Quick Charge 2.0, and Quick Charge 3.0. In the following section, we will provide a brief introduction of the latest version, QC 3.0.
全名Quick Charge，簡稱為QC。是美商高通公司研發的晶片中的快速充電技術，能夠讓有支援技術輸出或輸入裝置的充電速率能快於標準USB，又可稱QC快充。基本上可分別為Quick Charge / Quick Charge 2.0 / Quick charge 3.0三種技術層面，以下我們簡介最新的QC 3.0 技術為主。
Special Characteristics of QC 3.0 .Basic features of QC 3.0 include:
The first instance of using the Intelligent Negotiation for Optimum Voltage (INOV) algorithm.
QC 3.0 的基本特色我們可以歸納為：
首度採用最佳電壓智慧協商（Intelligent Negotiation for Optimum Voltage, INOV）演算法。
1.QC 3.0 is backward compatible. It can be used with devices equipped with older versions of the Quick Charge technology, including QC 2.0 and QC. Furthermore, hi-tech products equipped with USB-A/USB-C ports are also supported.
QC 3.0 具備向下的兼容性，可與具備快充技術舊版本相容，包含QC 2.0 與QC。並同時支援具備USB-A / USB-C兩種端口型態的科技產品。
2.Compared to Qualcomm's QC 2.0, its charging efficiency is 38% faster.
3.When charging with QC 3.0, it will automatically select an appropriate voltage within the range of 6 V and 20 V. It can charge your mobile devices under optimal conditions and with minimal power loss. Furthermore, it can improve heating and efficiency issues.
QC 3.0 會於 6V 至 20V 的電壓提供範圍中給予自動選擇。讓您的行動裝置可以在在理想的狀況下，損耗電能最少，並改善發熱與效率問題。
4.When charging devices which support QC 3.0, it will only take 35 minutes to charge a battery from 0 to 80%.
