The main difference between them, I think should be the use of different charging scheme, flash charging line data line should be relatively thick. At present, there are two kinds of fast charging schemes for mobile phones, one is high voltage and low current, and the other is low voltage and high current. The flash charging data line is generally a low voltage and high current scheme. Then, the voltage of its charger is relatively low, but its current passes through larger, if the current passes through larger, then its data line will be thicker, which refers to the charger of the same category. If it is a relatively large wattage in general, referring to more than 67 watts, then his charging line is basically no difference, all are more than 5~6a.
Fast charging and flash charging are both fast charging technology, but the principle of the two is not the same, fast charging is used to improve the charging voltage and speed up the charging speed. The flash charge is to increase the charging current and speed up the charging speed. The essence of both methods is to improve the charging power, the greater the power, the shorter the charging time. In addition, the low voltage and high current of flash charging will have a higher safety factor than the high voltage and low current of fast charging, but the versatility is poor.

Fast charge technology is to increase the charging power of the mobile phone by increasing the voltage during charging, thereby reducing the charging time.
Fast charging may take more than an hour, flash charging as long as 4 to 50 minutes.
