    Speaking of the magnetic interface, users who have used MacBook in the early years should know very well that when the data cable interface is close to the charging interface, they will automatically attract each other by magnetic force, and the “plug and plug” action can be completed with one hand, which is very easy to use. convenient. Such a good charging experience can also be achieved on a mobile phone, and only a magnetic charging cable is required.

    Step 1. Appearance and basic specifications


    Model: IET2020C3
    Material: Nylon+Aluminum alloy
    Connector :USB C/ Micro/ Lighting
    Power: 10W
    Output: 5V 2A
    Length: 1M

    The measured line length is 104CM,Meet the daily use of charging and data transmission.

    Step 2. Functional test

    cable resistance test,The resistance is only 0.0021 ohms, which is very small.

    Step 3. Disassemble

    The joint is a detachable magnetic design. Very fashionable, users only need to put the connector on their phones, when the phone need to charging just magnetic the cable. Reduce the damage to the mobile phone interface by plugging and unplugging.

    The front and back of the cable have the same design, and the aluminum alloy shell is smooth and shiny.Suitable for customer OEM own LOGO in this position.

    There are 7 contacts at the magnetic cable. 4 coils can be connected at the magnetic joint. Strengthen the magnetic attraction.

    Remove the aluminum alloy shell and peel off the glue layer. You can see the PCB and solder joints. The four wires are connected to both sides of the PCB.

    Let us cut the cable and take a look at its internal structure. It can be seen that under the nylon braid is a white PVC skin with four wires inside, each of which is composed of pure copper wires. Red and black are power cords, which are thicker. Green and white are data transmission, which is relatively thin.

    The disassembly is complete, and all the accessories are taken photo together.

    Step 4. Summarize

    The overall feel of this thread is relatively soft. The characteristic lies in the magnetic design, which can better protect the mobile phone charging joint. It is convenient for driving people to charge, or it is more convenient to use in the case of insufficient light and poor eyesight. No need to spend time and energy to find the charging joint on the mobile phone to realize one-handed charging. Compared with the traditional integrated cable, this design is also more novel and more suitable for young people who like to try new things.
