Flash charge is a fast charging technology that provides higher power output for charging devices in a short period of time. According to different technologies and standards, there are several common types of flash charging:
< br >
1. Qualcomm Quick Charge (Qualcomm Flash Charge) : Developed by Qualcomm, widely used in Android devices. It uses a special communication protocol that can provide higher power output from the power supply, thus speeding up the charging speed.

It is important to note that different fast charging technologies are usually only compatible between specific devices and chargers. Therefore, when choosing chargers and devices, it is recommended to ensure that they support the same fast charging technology for the best charging results.
As far as I know, there's wired fast charge, wireless fast charge, and reverse fast charge.
