So if USB stands for universal serial bus, that, to me, means there is only one stream of charge, however some cables are significantly faster than others. Is this due to the width of the cable? Or quality of the material in the cable?
In: Technology
Resistance: longer cables and/or those with thinner wires will have a higher resistance, which may limit the power that the device can charge at. Also, copper has a lower resistivity than aluminum, but is more expensive.
There are also some cheaply made cables that lack any conductors for the data pins, which may prevent the device and host from recognizing that they are supposed to be a charging setup, preventing higher currents from being drawn.
