The red line is positive. USB cable A total of four pins, of which two pins are data cables, two pins are power cables including grounding, red line: positive power terminal (the identification on the wiring is: 5V or VCC)
White line: negative voltage Data line (identified as: Data- or USB Port -)
Green line: positive voltage Data line (identified as: Data or USB Port)
Black line: Ground (marked by: GND). The general arrangement order is VCC, D-, D, GND, the arrangement is fixed, but there are two directions, the wrong connection of the data line can not identify the usb device at most, the power line must not be connected wrong, it is recommended that you read the motherboard manual or use a multimeter test.
Each USB interface can provide a current of +5V 500MA to the peripheral, if the connection is reversed, the light will burn the usb device, the heavy motherboard will be scrapped.
And very quickly, usually within 10 seconds of smoke.
The sequence from left to right is: red (power supply), green (data line 1), white (data line 2), and black (grounding).
The four wires in the data cable are: red is the positive electrode of the power supply, black is the negative electrode of the power supply, green line is the positive electrode of the data transmission, and white line is the negative electrode of the data transmission.
Some high-quality data cables will be wrapped with aluminum foil inside the four wires to resist outside interference, so as to achieve a better data transmission effect. The high-quality data cable is made of pure copper, fast charging speed and fast transmission rate.
Daily mobile phone charging only uses two lines in the data line, that is, a red line (positive) and a black line (negative) responsible for providing charging current.
The general arrangement is: red, white, green and black from left to right

USB is a commonly used PC interface, only 4 lines, two power supplies two signals, it should be noted that do not put the positive and negative terminals, otherwise it will burn the USB device or the computer's south bridge chip.
The data line on the charger is DC charging, there is no fireline and zero line, only positive and negative points!
Red, white, green and black are the standard wiring colors, corresponding to pins 1, 2, 3 and 4 respectively;
The four wires are 1- power 2- data 3- data 4- power
The general arrangement is: red, white, green and black from left to right
