Why can't the phone charging cable charge Bluetooth headphones?

Mobile phone charging cable and Bluetooth headset interface is not the same, mobile phone charging cable is generally Micro USB or Type C interface, and Bluetooth headset is generally Micro USB or Lightning interface. Even if it is the same interface, it can not be charged directly, because the battery capacity and charging voltage are different, which may damage the device. In addition, Bluetooth headphones need a special charging box to charge, because the charging box can control the charging voltage and current to ensure charging safety and charging efficiency. Therefore, we should use the correct charging method and pay attention to the charging requirements of the device to protect the device and extend the service life.


Cell phone charging cables can't charge Bluetooth headphones because they use different charging ports. Mobile phone charging cables usually use Micro USB or USB-C ports, while Bluetooth headsets usually use Micro USB, USB-C or Lightning ports. The shape and pin arrangement of these interfaces are different, so it is not possible to directly connect the charging cable and the Bluetooth headset for charging. In order to charge a Bluetooth headset, you need to use a charging cable or charging dock specifically designed for it.


Generally, the situation like this is because the connector of your phone's charger and the connector of the Bluetooth headset charger are different, just like when we go to plug in the socket, one is three holes, one is five holes, and this situation is definitely not universal
