It is not only a car cup holder, but also a good phone card slot. The car cup holder extender can hold the driver's and co-driver's cups or drink cups at the same time. The base and drink cup base can be freely rotated 360. Allows you to adjust the drink base to any position that does not hinder your driving, and the phone or card slot can be placed on the left or right side, making it easy to take hands-free calls, or charge your phone. Keep the mobile phone within of sight at all times without blocking of sight to your driving safety. The bottom is equipped with non- silicone, which can make the car cup holder stand firmly on the cup holder during driving, so that your mobile phone will not fall, and water and drinks will not shake and overflow.
