If you look at the plug of a the USB cable you’ll see it’s got 4 strips of metal.
Each of those strips plugs into a wire. The cord is actually 4 wires surrounded by a protector.
The left and right most strips carry power.
The middle two carry data.
There’s two for each because one is positive, the other is negative.
If you’re security conscious, you can slice open the protector.
The middle two (data) are connected to the white and green wire.
So if you cut those two, you can use the cable to charge from any random charger without worrying that someone is going to try installing things onto your phone via the wire.
