Portable Lab Power Supply

This is the portable lab power supply I built to meet my own needs. Since it's been incredibly useful for me as a maker, I decided to share it with you!

To build this device, you'll need to purchase a few electronic modules and have some basic soldering skills.
 

I do have a stationary bench power supply on my worktable, but I often work in other places—like at my PC desk, on the floor, in the car, or even outdoors. Very often, just to check something, I had to grab a device and bring it to my worktable. That was often annoying due to the weight, time, or space constraints.

So I came up with the idea of creating a portable power supply that covers 99% of my power needs, is compact, and can even power my USB-C soldering iron. Since I built this one, I honestly can't remember the last time I used the stationary one (of course, that depends on everyone's individual needs).
