Problems solved by technology

[0003] The traditional USB data cable charges mobile electronic devices without supervision. After the battery is fully charged, the power supply is not disconnected in time, which will waste electricity at least, and cause the battery to be overcharged and even explode. , so a 5VUSB data cable with full charge and automatic power off is urgently needed
