Problems solved by technology
When the USB is plugged in to charge the charging box and the charging box is charging the Bluetooth headset, the traditional solution is to charge the rechargeable battery through the USB, and then charge the wireless headset with the rechargeable battery. The whole process will lose about 15% of the power due to two-stage conversion.
