The Black Shark 4 and 4 Pro have been teased with 120W fast charging. The official poster went into a bit more detail – 4,500 mAh battery can be filled in under 15 minutes by the 120W charger. And now, thanks to a 3C certification, we have details on the charger itself.
The MDY-12-ED is the power brick in question. It tops out at 20V output at 6A current with a note “only for altitude 5,000m and below”. That shouldn’t be a problem as a quick check of Wikipedia shows that there no major cities anywhere near the 5,000m mark. Presumably, this is regarding charging on planes.
