I'm wondering how long it will be before this is used in a malicious way. Here's a translated quote:
Using BadPower, an attacker can invade a charger and other devices that support fast charging technology, causing the invaded device to output an excessively high voltage when it is externally powered, resulting in the breakdown and burning of components of the powered device, and may even further damage the received power. The physical environment where the device is located poses a safety hazard.
