I have designed a power bank specifically for a mobile router, which allows it to be used for up to 7 hours without needing to be connected to a power outlet. It features a 7812, Step-UP, and BSM 3S circuit, along with three 2500mAh Li-ion 18650 batteries. I haven't completed the wiring and final design yet, but I will share the final version once it's finished :)

There is a socket at the back that provides a 12V output to power the mobile router and also allows it to be charged from there.

On the front side, there are LEDs that indicate the charging status.

I used xDesign for the design and Keyshot for visualizations.
