    a usb cable has 4 wires. 2 for power, 2 for data. some cables are used just for charging and only need 2 wires. to use data you must have one with all 4 wires otherwise its just a charging cable.

      Since USB 3 came out in 2008, USB has used 9 pins, and USB C connectors use 24 pins. Saying USB has 4 wires is like saying cars have 3 speed transmissions. That used to be the standard, and there are still some around, but it isn’t a correct, or is at least an incomplete/misleading statement.

    Unless you're imitating Drax, your question is incomplete or mistaken.

    Not sure if you meant "what", but some USB cables are just for power, where the "data" pair of wires are sometimes missing. A USB data cable has the "data" pair and can be used for power and data. If you really did mean why, then it is a competing "serial" data cable, meaning it only needs two wires for data, where each version obtains a higher and higher data throughput. It has beat out other serial cable technology.

    Because it's an effective design.

      It’s an accepted design, and meets most people’s needs, but I wouldn’t say it is a good design. Particulary, the older micro USB 2.x connectors. They are very fragile, which is terrible for something like a phone that is constantly on and off its charger.
