The reason why the Bluetooth headset cannot be charged in the charging bin is: the situation caused by the poor contact of the charging port of the charging bin (or headset).

The solution is: if the charging bin (or headset) charging port is in poor contact, it is necessary to contact the seller of the Bluetooth headset in time to deal with the charging bin (or headset) charging port to solve the problem of not being able to charge.

It can be understood that the Bluetooth headset is equivalent to the exclusive mobile power of the wireless Bluetooth headset, and the built-in battery provides USB-C or MicroUSB and other data interfaces, so it can be charged directly through the charger, regardless of whether the Bluetooth headset is in the battery compartment. The headset in the charging compartment will preferentially charge the battery in the headset when plugging in the data cable to charge.
