130W Power Bank - QC4.0 & Power Delivery

thingiverse

I built the power bank by assembling a 5s Li-ion battery, hooking it up to a BMS, and adding a few more modules to make it all work. The Power Bank has 3 USB Type-C ports for charging and I added an OLED Display which shows detailed information about the battery inside. You can check the voltage of each cell, the total battery voltage, and the battery charge percentage.

You can use some old 18650 cells, pair them with a few more components, print a case, and assemble it all together!Components used:Arduino Nano: https://s.click.aliexpress.com/e/_DF3H0bTI used the "Mini" version5V Regulator: https://s.click.aliexpress.com/e/_DnkuIxTResistor Kit: https://s.click.aliexpress.com/e/_DDeQzNL5S BMS: https://s.click.aliexpress.com/e/_Dep9MP5Fast Charge Module: https://s.click.aliexpress.com/e/_DCA65shOLED Display: https://s.click.aliexpress.com/e/_De9pfMvPush Button Switch: https://s.click.aliexpress.com/e/_DFAQcNPI got a 12mm one, 3-6V, Momentary, BlackI would suggest you get the 12-24V version since my LED died3mm LED Holders: https://s.click.aliexpress.com/e/_DkPJjKH3mm LEDs: https://s.click.aliexpress.com/e/_DeVmaBFM3x25mm Bolts: https://s.click.aliexpress.com/e/_Dev4lrfM3x12mm Bolts: https://s.click.aliexpress.com/e/_Dev4lrf5x5mm M3 Inserts: https://s.click.aliexpress.com/e/_DlU5gNXM3 (OD 5mm), 5mm Lenght5S USB Charger: https://s.click.aliexpress.com/e/_Dl7UAcd-This module goes out of stock fast so the link may not work18650 cells - try to source them locally, I used Samsung 30Q cellsUSB Type C Tester: https://s.click.aliexpress.com/e/_DBB8caZUSB Type A Tester: https://s.click.aliexpress.com/e/_DlpwuHf
