    As more and more Type-c interfaces are used in various digital devices, the demand for Type-C cables is also increasing. Like the previous generations of data interfaces, Type-C also has both data and current transmission functions. Naturally, I care more about current transmission capabilities. The following is an evaluation of a USB3.0 Type-C data cable.

    1.Packaging and appearance

    High-end packaging box with UV and gravure design on the surface. The combination of black and green looks more mysterious.

    Open the lid on the surface of the box, which is attracted by a magnet. There is a visual window inside to see the product. The cable is fixed and protected by blister and it is also more convenient to display.

    The wire is tied up with a white leather strap, The material of the Cable is TPE, and the surface is very smooth.

    The rubber core adopts the blue color commonly used in USB3.0 specifications, and there are 5 reeds in the back, which are standard USB3.0 plugs.

    The overall length of the cable, including the plugs at both ends, is about 103cm.

    The wire diameter is about 4.35mm, which is quite thick, which reduces the convenience of daily carrying.

    The net weight of the product is 30g

    2. Function test

    The test voltage is 5V, and the maximum current is 3A

    3. Dismantling report

    Disassemble the plastic shell, the connectors inside are all wrapped by plastic.

    There are core welding on both sides of the PCB.

    Cut the white outer skin of TPE, you can see that there is a layer of shielding net inside.

    There is also a layer of aluminum foil inside the shielding net, double-layer shielding, and double-layer protection.

    Remove the aluminum foil layer to reveal the cores of various colors. Black and red are power cords. The others are data transmission lines.

    The blue wires we saw just now also have shielding layers, and there are two wires inside.

    Dismantling is complete, take a group photo


    Because of the limitation of the A port, the A TO C cable can only achieve the USB3.0 protocol. The material used for this cable is strong and it is completely in accordance with the standard 3.0. The shielding layer and tin foil are complete, the internal resistance is amazing, and the internal cable is thick. Make the whole line thicker, of course, without sacrificing performance. In short, this is a rare A TO C line. I hope that the new brand will not forget its original intention and move on.
