This is a simple insert for the car cup holder that can hold your phone. An additional feature is that there is a slot to keep your USB cable in place when it is not connected to the phone.
This model is incredibly practical if your car has Google's Android Auto or Apple's CarPlay , or if you just want to manage the cables while charging your device!
It has originally been designed to hold a OnePlus One in an Opel Corsa (E). The default settings for the USB slot should fit most common micro-USB cable ends.
