Perfect Tesla Car Mount Charger!
This charger is amazing! Fits my Tesla screen perfectly, charges my phone fast, and the magnetic hold keeps it secure. Love the LED RGB lights and heat protection — looks great and works flawlessly. Highly recommend!

Would be better with longer cable and without the LED light.
I like that the install is very easy, non-permanent, and can be very quickly removed if needed. It fast charges and the magnets are strong (the reviews that say it doesn’t hold probably aren’t using a MagSafe case). That said I have two annoying issues: 1) There is a light that comes on when the car is turned on. If you don’t put your phone on the charger it will say on for a minute or two and then eventually turn off. 2) The included USB-C cable is too short. It only just barely reaches the outlet in the front bottom center console. It would be better if they had included a 6ft with a 90-deg connector to draw power from the back seat ports. 3) It doesn’t not include a charger. In all, the mount and charger are fine, but be prepared to spend an extra $20 on a longer cable and charger to make it all work.
