S7 Fast charge not working

[AC Question]

My s7 I've had for a few months now has been speedy with fast charge and I loved it. I recently noticed it's taking me ages to charge my phone. I timed it one day and got 3 hours and 11 minutes from 1% to 100% and when I looked it up on the internet it is supposed to be like 1 hour and 22 minutes. I have it enabled, on the drag down menu I it says fast charging, my block is the one that came with the phone and my plugs are in all the way... can anyone help me?

The Key to get a Fast charging is to use the white cable and
adapter according with these comments - But I believe
the post -18 on this thread maybe correct solution
