Had a USB female end coming from a pioneer DVD radio that I had used for my iPhone in my truck. Figured I just needed a USB A to USB C cable to make it work with my new Android phone. Didn't work at all but I think because the pioneer was set up for Apple or just didn't recognize the Android format. Either way couldn't play my Android phone over my pioneer stereo..and no it didn't have Bluetooth which is why I bought the cable.
I bought these to use in the car with my dual port car charger. After receiving them, it seemed that one worked and one didn't. However, after playing with them further, I figured out that the USB A side connector into my charger is very picky and has to be pushed a certain way to work correctly. Not the best choice for my particular use.
