2 in 1 car cell phone holder: can hold cell phones and drinks in the car, providing high stability. The cup holder is made of high quality PC, so it is very durable and strong and will not break or wear out easily. The interior dimensions of the drink box are 8 .5 cm in width and 5.8 cm in height, which makes it easy to place drinks of different thicknesses and stabilizes the cup well. Spring-loaded protective fins are located on both sides of the area of phone placement and have a flexible range of approximately 16mm from left to right, allowing you to place your smartphone more easily. This makes it easier to keep an eye on the navigation system while driving. Easy to install: it can be installed on the air conditioning vent and can be easily removed. No additional tools required and easy to use. In summer, coffee drinks are cooled by the ventilation grill (if the vehicle is air-conditioned) and kept warm in winter.
