This is a car phone holder I used previously. I'm selling it because it's a waste to throw away. The second and third photos show a magnetic type that attaches with a suction cup. The arm is adjustable in angle and can extend, and the magnetic part is a ball joint. The fourth and fifth photos show a charging type that attaches to the air conditioning vent (charging via micro USB, charging operation confirmed). The side arms open with the button on the top of the back. The sixth and seventh photos show a magnetic type that attaches with double-sided tape. It's a ball joint.
