Premium Charge Cable for PlayStation 4
Yes it can connect to your ps4 Controllers.
Yes this ps4 charger should work. If it doesn't work then you should try it on your 2nd USB Port on your ps4 and if that doesn't work then you should get your USB Ports Checked out because that could be the reason why it isn't charging up your controllers.
If the controller is compatible with PC then yes.
Yes, it works just like any other mini USB charger :)
I purchased my charging cable about 5mos. ago and it still works like the 1st day I brought it. It's a really thick cable. I'm unsure of how long it last but so far so good.
