Mount for securely attaching a smartphone to a vehicle's air vent. The car phone holder is compatible with smartphones that are 5.5 to 8.5 cm wide. Access to the smartphone's charging port remains unobstructed, allowing the device to be charged while driving. The phone can be rotated as desired, for example, for horizontal navigation. By adjusting the tilt angle, an optimal view of the display is always possible, even in sunlight. The smartphone holder is attached to the air vent without any adhesive or drilling, making it suitable for almost any car and easily removable when needed.
