- Dec 12, 2017-

Compared to Qualcomm earlier launch QC2.0, QC3.0 fast charging technology, Qualcomm QC4.0, QC4 + penetration rate is not high. However, the new QUALCOMM QC4 + fast charge technology compared to previous generations of fast charge technology has been a qualitative change, that is, to support the USB PD fast charge agreement. USB PD has some magical features, so that Apple, Google, Qualcomm are open?

In early 2017, USB-IF released a major update to USB PD 3.0, introducing a fast charge specification called PPS (Programmable Power Supply). The new USB PD 3.0 will not allow the USB interface to be voltage-regulated with a non-USB PD protocol. At the same time, USB PPS and China's Ministry of Industry and Thail Laboratory reached a cooperation expected future as a national standard mobile phone charge. For smartphones, the most critical is that Google in the latest Android 7.0 OEM specification emphasizes: fast charge technology must support USB PD. At this point, fast charge standard usher in a mandatory unity.

Today, George Paparrizos, Senior Director of Qualcomm Wireless Communication Technologies (China) Co., Ltd., said at the Tell Forum 2017 Fast Charge Technology Standards and Applications Seminar that Qualcomm's current QC4 + fast charge standard will be backward compatible with its own QC3.0 / 2.0 , At the same time confirmed that it will merge with the USB PD fast charging protocol. The popular QC4 + charger will be a multi-functional and multi-protocol charger. The next 10 years, Type-C charging interface and USB PD fast charging standard will be dominated by rivers and lakes.
