55w wireless charger cannot be used. The reason is that the millet 12spro supports up to 67w wired fast charge, but only supports 30w wireless fast charge, so the use of 55w wireless charger will appear charging speed can not reach the maximum power, and because the charger exceeds the maximum charging power of the phone, it may also cause damage to the phone.
It is recommended to select a wireless charger below 30w for charging.
