If you have one of these thin Tzumi Qi chargers lying around, you can use this to repurpose it as a car charger!

Printed in ABS to stand up to the heat.

I did find that with a larger phone such as an iPhone 15 Pro Max the insert cannot be fully pushed into the slots or else the wireless charging will not engage. I solved this by using some double sided tape with it sitting slightly above the fully seated position.
