After charging is complete, the battery display is full, the equipment led turns green, and the LED indicator of the wireless charging board turns green.

If you use the old Low-power charger, such as 5v/1a or 5v/0.7a charger to connect the wireless charging board, the wireless charging board led will be bright blue-green, the charge can still be charged, but the charging speed and full power will take longer than normal time.
