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
In: Technology
Could be because of different fast charging stantards. Some may use USB PD or Qualcomm quick charge which use higher voltage (USB PD goes up to 20V) and lower current, therefore they don’t need thick cable. Others just use 5V and high current (Realme uses 5V 6A charging), and you need really thick cable for 5 or 6 amps. So if you try so use cable from a phone that uses higher voltage with a phone than uses high current, it very likely won’t charge at full speed. It should work other ways though.
