The MOST Versatile DIY Power Bank (Part 1) with USB QC, Wireless charging, RGB & More

This video is sponsored by JLC PCB
$2 for 2-Layer PCBs & $5 for 4-Layer PCBs: https://jlcpcb.com

This is the successor to my ultimate 18650 power bank, this version focuses on practicality, portability, safety, and more advanced controls. This power bank is also modular and customizable in that it can be connected to modules that convert the power to AC, DC, USB, or other forms. The removable battery of 92Wh (Samsung 50E) means that it is close to the largest battery legally allowed on an airplane. This development version of the power bank is opensource, links below.
