Whether it is mobile phone chip manufacturers Qualcomm or MTK, or mobile phone brand manufacturers Huawei, OPPO, VIVO, etc., have their own fast charge protocol standards, although these standards are incompatible, the principle is not the same, are to increase the charging voltage or current.
The original OPPO flash charging cable is a 7PIN plug, while the third-party brand data cable on the market generally uses the standard Micro 5PIN, which is different in structure, and can only be charged for ordinary charging, unable to achieve VOOC flash charging. After the original data cable is damaged, try to buy it on the official website. At the end of the year, OPPO opened the SuperVOOC super flash charge patent Open Day in Shanghai, and it is believed that more third-party digital brands will soon support VOOC flash charge.
Huawei's SuperCharge fast charge also belongs to the low-voltage and high-current scheme, that is, when the voltage is certain, the current is increased, and the parallel circuit is used to shunt. After the parallel shunt, the charging efficiency can be improved, and the heating pressure of the mobile phone and charging accessories can be reduced.
The Huawei P30 Pro is equipped with 40W fast charge, with a maximum output of 10V\/4A charging power, and backward compatible with 4.5V\/5A charging power consumption. To achieve Huawei SuperCharge fast charge, the rated current of the third-party brand data cable must be 5A or above.
