This. Is. A. PSU?
Yes, this is a PSU. It has a USB-C output and a regular screw terminal block input. It contains the IP6518 from Injoinic Semiconductors, which is an all-in-one USB PD Source Controller. This PSU can be pretty helpful in emergency conditions. It can charge devices with a maximum power of 45W. It supports many protocols, including but not limited to USB-PD, QC, BC. A case has been designed around it to provide ruggeddness from the environment. To use it, just plug in two wires into the screw terminal, and connect a USB-C cable, and you're working with it.
To assemble, put 2x M3 threaded inserts in the bottom enclosure, and then place the PCB over it, and cover with the Top enclosure, and screw it up!
I built this project not just for actually using it, but for personal experience with power devices, and specifically SMD electrolytic caps.

Questions
How big is the Psu charger PCB?
It measures 48 × 30 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Psu charger use?
20 parts, built around the IP6518. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.
Where can I download the Psu charger KiCad files?
From the Keyaan-07/PSU repository on GitHub, at the commit this page was made from: the board is hardware/psu-charger.kicad_pcb and its schematic hardware/psu-charger.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Psu charger design in my own project?
Its repository states no licence, so its author keeps all rights: ask Keyaan-07 before reusing the design.
