Bench Power Supply Power Leads

@arrowj Wow, that certainly looks impressive, my home made power supplies aren't quite so neat.

Even USB-C is only max 100W so not sure how that will power a soldering iron pencil. I have to admit I don't know the wattage, but judging from my own pencil it seems like an awful lot more than 100W.

I have banana plugs, various other 'ends' and a spool of 18AWG silicone wire with HD insulation thickness. Make anything I want. The 'standard' universal end thing is 4mm.

Have you seen Bill's power supply videos? There are two, one is for small stuff (95W laptop brick) and the other is several hundred watts from an old PC or in my case purchased as I have no old PC's kicking around.

Here is what I started with Set of leads

@zander

The first batch of Pinecil's were rated 12-24v @ 65W. After some heated discussion on the discussion group, it was decided that it would be downgraded to 12-21V @ 60W, due to concern over the connection of the DC jack to the USB-PD chip, which has a recommended maximum of 21v, and absolute maximum of 28v. --Pine64 Wiki

I have not used it yet as I am still waiting on some supplies, but I powered it with the Lenovo 65W GaN charger (PD 3.0) for my Laptop and it works a treat. Extremely fast, and that particular charger does not require adjusting the PD setting of the iron as is apparently the case for certain devices that do not negotiate power requirements quickly enough.

I was wondering about the size of connector and appropriate wire to have on hand. Thank you!! I also bought that kit (under different branding). I think it will handle most of my testing needs, and I am getting ready to use them now to get familiar with the power supply. Mostly I want to make up custom cables for charging Li-ion batteries, powering μcontroller boards, and things of that nature. I could also wire up a barrel jack for the iron I suppose. I am not sure if the PD circuitry is in both ends of a USB C cable and cutting one end off would ruin it. Maybe a barrel connector would be a better choice.

EDIT: I have not watched those videos, but one of them is in my queue. When I want a second power supply I intend to go that route.

It isn't a problem if your using a micro or mini usb. But type c has something called power delivery.

It allow you to get not only 5v but also 9v,12v,15v,20v.

This video from great scott makes it clear

@e-danil I was wondering if PD or QC chips built in to the cable would cause issues. A Great Scott video I have not seen. Added to my queue. Thanks!

@arrowj please watch the video to understand what I am trying to say

@e-danil I watched it immediately.  Great explanation. I am going to make up a barrel jack to banana cable instead. Thank you much!

@arrowj I am wondering where would you connect the barrel jack to. one side banana leads the other side what

@e-danil Banana leads to bench power supply and barrel jack to Pinecil
