OPPO fast charge and flash charge are different.
< p >
Fast charge: The charger is allowed to determine the initial voltage required for charging according to the current, and the pulse current command issued by the PMIC is transmitted to the charger through the USB Vbus. The charger adjusts the output voltage according to the command, and the voltage gradually increases to up to 5V to achieve the maximum charging current, and the charging speed is improved by increasing the current and voltage at the same time.
Flash charge: VOOC flash charge is OPPO's independent research and development of fast charging technology, and applied for 18 patents, the fastest charging speed increased by more than 4 times, and has impeccable intelligent all-end five-level protection, is the world's faster and safer mobile phone charging technology.
