1 is also a USB interface, with a data interface in the middle and one at the end to get electricity. When the power of one usb port is insufficient, another usb port needs to be inserted to increase the current. Otherwise, you will hear the sound that the mobile hard disk Kaka cannot rotate normally.
2. You mean that your data cable has three interfaces, the small interface is connected to the interface on the mobile hard disk, the two interfaces are connected to the USB interface of the computer to transmit data, and the remaining interfaces are only used when your mobile hard disk is connected to the computer and cannot be displayed normally, mainly to supply power to the mobile hard disk.
This is not a patent of SSK, and so is my other Maituo mobile hard disk. Good boxes and brands are equipped with three lines and can be purchased separately. The function is to supply power to the mobile hard disk with insufficient current to enhance the current, and the two nearest ones are connected to the computer. Only when the power supply is insufficient, it is necessary to connect the two.
4. Similarly, two of them are connected to the U disk and USB interface, and the other one is power supply auxiliary and also connected to the USB interface, but it is not connected in most cases.
5. Let me answer them one by one: Generally speaking, mobile hard disks use USB as the interface for data exchange, and a USB cable will be attached. It is the same as the use of USB flash drive.
1 is also a USB interface, with a data interface in the middle and one at the end to get electricity. When the power of one usb port is insufficient, another usb port needs to be inserted to increase the current. Otherwise, you will hear the sound that the mobile hard disk Kaka cannot rotate normally.
2.USB is a common pc interface. It has only four lines, and the general arrangement is: red, white, green and black from left to right. Red USB power supply: marked with the words "VCC, power supply, 5V, 5VSB". White USB data cable: (negative electrode)-data-,USBD-, PD-, USBDT-.
You mean that your data cable has three interfaces, the small interface is connected to the interface on the mobile hard disk, the two interfaces are connected to the USB interface of the computer to transmit data, and the remaining interfaces are only used when your mobile hard disk is connected to the computer and cannot be displayed normally, mainly to supply power to the mobile hard disk.
4. If some motherboards are short of power supply, use that slot. It is used to strengthen the power supply.
Please consult how to use the double-headed usb cable equipped with the mobile hard disk.
Single-headed and double-headed mobile hard disk is plugged into the USB port of the computer: one line in the double-headed is the auxiliary power cord, and two lines are the main lines.
When the data transmission speed of the hard disk is too slow and the current reaching the hard disk is too small, both data lines can be connected, which can improve the current transmission and data transmission speed. The short head is used for power supply and the long head is used for data transmission.
No, the voltage will not change. USB is 5V, and the two terminals are connected in parallel, which only increases the current. Because the current of a USB port is sometimes not enough, the mobile hard disk can't work normally.
The dedicated data cable of the mobile hard disk is used to supplement the power supply. There are two kinds of wires with USB interfaces at both ends: one is USB revolution USB bus, which is called USB extension cable; The other is USB to USB, which is generally used to connect computers, such as USB external sound cards and high-definition set-top boxes.
