Hi I am an embedded systems engineer with over 16 years of experience designing compact consumer electronics, custom PCBs, lithium battery systems, and wireless power products from concept through prototype and production files. This project is mainly a stack-up and feasibility challenge: 2.5 mm leaves very little room for the cell, coil/ferrite, PCB, thermal path, and enclosure, so I would first lock the realistic thickness/capacity tradeoff, then develop the wireless power/battery management PCB, ultra-thin mechanical CAD, BOM, Gerbers, and prototype assembly plan. Qi compatibility can be targeted, and Qi2 can be evaluated depending on coil, magnet, and certification constraints. I can provide the design files and support a fully functional prototype. Similar portable hardware and power electronics projects cannot be shared publicly, but I can show relevant examples privately if needed. A few details would help finalize the design direction: desired battery capacity, target phone models, required card/wallet dimensions, whether magnetic alignment is needed, and whether the first prototype is for proof of concept or investor/customer demo. Please contact me to discuss details.

⭐⭐⭐⭐⭐ I've carefully reviewed your project, and the biggest challenge isn't the electronics—it's achieving a truly functional 2.5 mm overall thickness while integrating the battery, Qi/Qi2 wireless charging hardware, PCB, and enclosure. This requires careful architecture and component selection from the start. I have experience designing compact electronic products, including custom PCBs, power management, battery integration, and production-ready hardware. My approach is to optimize the design for both prototype performance and future mass manufacturing. The project would include: System architecture and feasibility review Custom PCB and wireless power design Ultra-thin battery selection and integration Premium enclosure CAD design Manufacturing-ready Gerbers, CAD files, BOM, and documentation Functional prototype support and testing Proposed milestones: Feasibility study and system architecture Schematic, PCB, and enclosure design Prototype fabrication and validation Final production files and design handoff Before starting, I'd like to confirm the target battery capacity, desired wireless output power (5W/10W/15W), and whether Qi2 compatibility is mandatory or preferred. I can provide all editable design files and support development through a fully functional prototype.
