A:AnswerGakaxy A 51 don't know, but yes fast charging. I bought on line what i thought was a fast charger and cable lasted a month, so I bought the original cable that goes with my S8 and it works perfectly.
A:AnswerThis will fit any phone that uses a Type - C charging cable. This charging cable is for Type C port phones. I looked up the Samsung 9 and it says it is. Just make sure to look at the picture and compare your charging cable to this one. By the way, I purchased 2 of these and I am 100% satisfied! These are legitimate Samsung charging cables.
Good Vibration!
