OPPO VOOC flash charge is a low voltage high current fast charge, low temperature when charging, more safe. QC3.0 is high, low current fast charging, charging temperature is slightly higher, but the wire requirements are low, more convenient.
Flash charge is a fast charging technology that can make the mobile phone fully charged in a short time, independently developed by OPPO, and applied for 18 patents, which increases the fastest charging speed by more than 4 times, and has impeccable intelligent all-end five-level protection. Flash charge is to use the mode of low voltage and high current to increase the current, and MCU single-chip microcomputer is added to the charger power supply and battery circuit to replace the step-down circuit. Under the premise of low voltage and high current, the output of segmented cross current is realized by opening voltage loop. A charging method that can make the battery reach or approach the fully charged state within 1~5h. It is often used for charging traction batteries when they need to be restored to a fully charged state in a relatively short time. Fast charging is detrimental to battery performance and life.
The difference is: 1, the charging speed is not the same, flash charging is faster.
2, the voltage is not the same when charging, flash charging is low voltage fast charging, fast charging is high voltage fast charging.
3, the heating degree of the mobile phone is not the same when charging, the flash charging temperature is low, and the fast charging temperature is high.
