The charger has only one working state, that is, discharge (power supply), and charging is actually to discharge the battery. So for the charger, charging is also discharge, discharge one is to charge, the other is to supply power to other devices (to provide working power). Do you mean that when the charger is charging, the wireless router can not continue to be used, it is completely OK, but at this time the \"discharge\" is still the battery. Or you mean that the charger in addition to the normal charging port, there is a DC output interface, this interface can be used? If yes, this situation depends on whether the charger has a power surplus.
