Everything worked at first. After charging a USB-C phone for the past month, it now doesn't fit properly and won't charge the phone unless I press and hold it. Micro-USB is still great for charging my headphones, but I wanted a 2-in-1 device. Also, my Samsung phone doesn't seem to recognize "Super Fast Charging" with this connector. Fast charging only. I've been using a 4-in-1 connector with separate wired dongles for each phone in my car for a number of years and it still works perfectly. Connector C on this cable is defective.
