How come my Samsung s6 edge will only charge with one usb cable?

[AC Question]

Hello, so the other day I was able to use multiple usb cords to charge my s6 edge. Now today only one of my usb cords charges my phone. I've tried switching the cords around into different ports. But none of them work. Only my one black cord works. What's the reason for this? & how can I fix asap. Help pleaseeee
