If his new number shows that it is full, then it proves that he is full, if there is no signal display?

You can basically charge after a period of time, because sometimes the link is automatically disconnected after full charge, as long as you see his charging temperature. If there is a signal indicator, then look at the signal indicator, if not, you can only determine the approximate time.
When the charge light goes off, it's full. When wired charging is full, the indicator light is green, and when wireless charging is full, the indicator light is off.
The charging box is connected to the USB-C charger, and wired charging is carried out for the charging box. The specification of the charger is above 5V\/500mA, and the charging current is greater than 2A, which can achieve the fast charging effect.
