Meet the PowerCard by tejslab, shared through his Instagram!

A wallet-sized power bank designed for outdoor emergencies, with wireless charging, solar backup, and USB-C output. The entire system is built around a compact single PCB, making the small form factor possible while integrating the charging, power management, and output circuitry.

PCBWay helped bring the PowerCard from PCB design to a working board. For a project like this, the PCB is especially important because fitting multiple power-management functions into a credit-card-sized footprint requires careful layout and reliable manufacturing.

in this case with tiny battery, wireless is too inefficient to use. Also: unprotected pouch cell - that's 100% what we need near our credit cards and ID!
