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, the fastest charging speed increased by more than 4 times, and has impeccable intelligent all-end five-level protection, is the world's fastest and safest mobile phone charging technology. Flash charging technology is based on the mode of low voltage and high current, under the premise of fixed power, by enhancing the voltage or current to shorten the charging time. 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.
Flash charge means to increase the current of the mobile phone to achieve the effect of fast charging. The charging method of the mobile phone usually has the function of flash charging and charging, flash charging means that by increasing the charging current of the mobile phone, the mobile phone power is quickly filled, this way is flash charging
Fast charging of the phone. Flash charge reduces voltage and increases current Many brands say flash charge, the principle is to improve the charging current. In the case of constant voltage, the higher the current, the less time the battery will be fully charged.
Flash charge is also a unique term of OPPO plus, the difference between the three technologies is that OPPO, the flash charge technology advocated by one Plus, is a simple and rough charging method, directly using 5V voltage to transport 4A current, while Qualcomm and Mediatek's charging scheme is to increase the voltage and then increase the current, so flash charge technology can also be called high-current charging technology.
So flash charge and fast charge that is a little faster, from the market effect, the difference between the two is not big, but if you want to say, the fastest charging technology on the market at present, or the number of OPPO Find X Super VOOC, which is currently commercially put into the highest end of the charging technology.
Flash charging uses low voltage and high current, which is higher than the high voltage and low current of fast charging, but the versatility is poor, only official accessories can be used, fast charging and flash charging are safe.
