Hello, generally speaking, you can directly use the usb socket to charge the Bluetooth headset. However, it should be noted that the voltage and current required by different brands and models of Bluetooth headphones may be different, so it is best to use the original charger or compatible charger to charge to avoid damaging the device or shortening the battery life.
The answer is as follows: Yes, the Bluetooth headset can be charged directly with a USB socket. Many Bluetooth headsets come with a USB charging cable that can be plugged into a strip USB socket or a computer USB port for charging. However, please be careful not to use too much power or charger to avoid damaging your headset.
No, because the voltage is too high, the Bluetooth headset can not directly use the USB socket when charging, because the voltage is 12 volts, so it will cause the Bluetooth headset to be seriously burned, so you should use a professional charger to charge
