DO NOT BUY THIS PASSIVE CHARGER.

I had an S5 and currently an S9, never had charging cord problems with the S5, and so far the same with the S9, and 2 of the cords I have were extra cords I bought to use in the car for the S5, the S9 plugs are different, I have adapters on those 2 S5 car cords to fit the S9 jack and still no problems with charging.
