QUALCOMMQUICK CHARGE BRIEF INTRODUCTION

QUALCOMMQUICK CHARGE BRIEF INTRODUCTION:

Now mobile phone quick charge technology can be divided into two categories, the first is a high current charge, keep the 5 v voltage, after starting quick charge to 4 a to 5 a high current charge, using the technology currently only OPPO VOOC flash filling technology. The second is to use high voltage fast charge, after the quick start charging can take 9 v to 12 v high voltage charging, the charging current can keep between 1 A and 1.8 A, have A safe charging current, the qualcomm QC2.0 and mediatek Pump Express Plus technology, represented by the quick charge scheme has been integrated into the qualcomm and mediatek chip package.

Another qualcomm QC2.0 technology is open, so some non qualcomm chip could also see some on your mobile phone based on qualcomm QC2.0 derivative quick charge technology, such as huawei BoostMaster of quick charge technology and asus.
Qualcomm Quick Charge 2.0 what is the principle of Quick Charge fast charging method?
QC 2.0 introduce
• what is qualcomm? Qualcomm is a company that specializes in mobile phone chips, currently on the market of mobile phone chips not qualcomm is mediatek (except APPLE).
• what is QC2.0? This protocol is developed by qualcomm in 2014, in charge of A specification, points the class A (5 v, 9 v, 12 v) class B (5 v, 9 v, 12 v, 20 v) two kinds, is using the D + D – the change of voltage to control the charger
