A:AnswerThe cable has an Apple Lightning plug on the end, which will only work with Apple products. I use mine to charge an iPhone SE (2nd gen.). Charges it in about 1 to 1-1/2 hrs (depending on how low it was to start). This can be used with iPads as well.
Samsung S9 needs a USB-C plug, so you'd need a cable with USB-C plugs on each end to work with this block that plugs into the wall socket.
