Qualcomm 2.0 wall charger technology

Qualcomm 2.0 wall charger technology

Mobile phones in people's daily life plays a more and more important role, I believe many people see the mobile phone the remaining power of less than 10% when will begin to anxiety, in the last year, almost every phone conference, vendors will be referred to support the fast charge, in hammer T2 showed that there is no fast charge, many users have on this began to crusade. Fast charging had almost become a standard, so today we are going to see now what the Qualcomm 2.0 wall charger technology, this year's rapid charging and the how to develop.



Gradually become the standard of intelligent mobile phone Qualcomm 2.0 wall charger technology.
Qualcomm 2.0 wall charger is mainly through improving the charging power to achieve the purpose of fast charging. The fast charge is divided into two, one is current constant pressure increases, such as charging for five minutes, call two hours "vooc flash charge, and another is is constant current voltage increases, this is represented by Qualcomm quick charge and MediaTek pump express plus  technology. First of all, we are currently in the sale of mobile phones in the mainstream of the three kinds of fast charging solutions to understand.
Quick Charge 2: equipped with Qualcomm Xiaolong 800 series chip, HUAWEI mobile phone fast charge, ASUS BoostMaster



Gradually become the standard of intelligent mobile phone fast Qualcomm 2.0 wall charger technology.


Qualcomm 2.0 wall charger technology is in 2013, Qualcomm launched Xiaolong 800 times have been integrated fast charging scheme, along with the upgrading of Qualcomm CPU product line, in Xiaolong after 800 products support Qualcomm 2.0 wall charger technology, its principle is also increase voltage and current to enhance the charging speed, the charging voltage from 5V to 9V, and the charging current is increased from 1a to 1.6A. Support 5V, 9V, 12V three voltage QC2.0, with a high voltage to the charger can be compatible with more use Qualcomm SOC devices, and to prevent damage to the battery caused by high voltage, high QC2.0 also join the special IC control chip, improve the charging safety. Another Qualcomm QC2.0 technology is open, so some of the non Qualcomm chips on the phone can also see some of the fast charging technology based on Qualcomm QC2.0, such as HUAWEI's Qualcomm 2.0 wall charger technology and ASUS's BoostMaster.

Pump Express MTK fast charge technology: Meizu mCharge, etc.

Gradually become the standard of intelligent mobile phone fast charging technology.

Pump Express MTK fast charging technology is divided into two kinds, one with a Plus without Plus, with Plus can provide 24W (12V) and even higher output power, without the Plus can provide 10W (5V) output power. Currently equipped with the MT6795 family of mobile power and Meizu mCharge mobile phone belongs to this category of products.

Compared with the ordinary charging, Qualcomm 2.0 wall charger Express Plus Pump fast charging Qualcomm 2.0 wall charger technology can reduce the charging time of mobile devices in half, significantly shorten the waiting time of the user. The mobile device using the Qualcomm 2.0 wall charger technology can be compatible with the existing charger, no need to attach additional lines, but only to support the Express Plus Pump technology to achieve rapid charging charger. Express Plus 24W can provide Pump (12V) and even higher output power, fully able to meet the charging needs of high capacity battery. In addition, for the rapid charging of low capacity batteries, Qualcomm 2.0 wall charger technology has also developed the Express Pump technology, can provide the output power of 10W (5V).

VOOC OPPO flash charge: R7 OPPO, etc.

Gradually become the standard of intelligent mobile phone fast Qualcomm 2.0 wall charger technology.

At 5V charging voltage constant, increase the charging current to the 4A-5A, using parallel circuit shunt, so oppo vooc technology need to use special charging cable for oppo vooc technology, oppo vooc charging line interface eight electric shock, can realize the multi-channel 5V charge, so as to enhance the mobile phone charging speed. In the mobile phone has been listed for sale, oppo vooc flash charging rate is indeed the fastest, 30 minutes can be the 3000mAh cell filled with 75%, so the realization of charging 5 minutes to call the difficulty of 2 hours of talk time is very small. But VOOC flash charge the biggest drawback of the unique 8 pin interface and data lines, which makes it only applicable to a OPPO product, poor compatibility.
