I have a OnePlus phone and I know that to fast charge it I need to use a special USB cable.
But Samsung phones, for example, also have their own fast charging cables.
So why can’t those phones fast charge with the other manufacturer’s cables if the cable is able to transfer enough power anyway?
At the end of the day the cables are simply transferring electricity, and the more watts the faster it should charge, no? At least that’s the way I see it
