There is no problem and the power can only be 40w.
As long as the voltage of the charging bank and the voltage of the data line can be equal, it can be charged any way. Both sides are fine.
45w, that is not Huawei's charging head, Huawei fast charge is a private agreement, 40w certainly can not reach,
Wireless charging probably also wants Huawei's own, or qi, anyway, there is no 30w.
It can be charged, and the regular charger can automatically adjust according to the charging power supported by the phone.
