From the point of view of the charging plug, the fast charging principle of fast charging and flash charging is the same, but the method is not the same, among which the common fast charging is to improve the charging power of the mobile phone by increasing the charging voltage, so that the charging time of the mobile phone can be reduced, and most mobile phones use this technology

The flash charge is to speed up the charging speed of the mobile phone through the form of low voltage and high current, so the plug of the two chargers should not be used carelessly, and the wrong use will damage the battery to a certain extent.

In simple terms, you can draw an equal sign in your head, fast charge = high voltage, flash charge = low voltage, obviously, although fast charging can be achieved, but the difference in voltage and current, the impact on the mobile phone battery and circuit board can be huge.
