No, the Honor 30pro phone does not support reverse charging, but it has a built-in 4000mAh battery and supports 40W wired fast charging.
The 40w wired fast charge of the Honor 30pro uses an exclusive charging protocol to achieve fast charging, so the original charger must be used to achieve it. When charging, there will be a super charging logo, from 0-100% charging time of about 58 minutes, the general temporary charging speed is also fully sufficient. It should be noted that the glory 30pro charging is not the whole 40w, the measured power will be reduced to about 24w at 60%, the trickle charging time at the back end is longer, in fact, it is not full, and the speed of 70% takes only about half an hour.
