This technology is characterized by reduce time that an electronic device, such as a mobile phone or laptop, requires to fully charge the battery. Today’s more advanced systems can complete charging in less than half an hour.

For it to work, the system is integrated both in the device to be loaded and in the one that is plugged into the current, specifically, in the firmware, and some solutions are also capable of transferring data, in addition to charging.

An attacker could use these problems to rewrite the firmware of the fast charge device to control the behavior of the device power supply.

clarified from Tencent.
