Quad Lock Wireless Charger

thingiverse

I wanted a cheaper alternative to Quad Lock's expensive wireless charger head to use with a Brodit Proclip in my car. I had to experiment quite a bit to find something that would work with the iPhone 12/13's reduced wireless charging distances, whilst also providing enough structural integrity to withstand the forces of attaching and detaching the phone to the quad lock. The result seems to function well, charging is reliable and nothing gets too hot. The hole mounting pattern for the base is 30x38mm with 3.3mm holes. It is designed for the ProClip system but could be mounted on anything. Here are the components I used: 3x M3 heat set insert 3x M3 8mm counter sunk bolts 1x M2.3 8mm self tapping screw (to secure PCB) 4x M3 10mm self tapping screw (to mount to ProClip) 1x 10W Qi charging module - I used [this one](https://www.aliexpress.com/item/1005002631844096.html) from AliExpress To assemble, glue the coil part of the module (with the wires facing towards the Quad Lock) to the top plate. Use a soldering iron to set the M3 inserts, then mount the base to the ProClip or mounting surface. Then fix the PCB with the single M2.3 self tapping screw, and fix the whole thing together with the 3x countersunk bolts.
