I want to turn all my power tools and batteries a universal connector like USB-C. I have a 3d printerand skills so getting the manual interface is easy enough, but I don’t a lot about ports and tech. I’m learning fast, but I’m not quite there yet.
From what I understand, I’d need to put a female port on the battery which isn’t difficult and has been done plenty for charging.
I’d need to put a male plug on the tools to interface with it, and my initial research says I can’t just solder the power pins to the cables in the tool, I’ll need a circuit board that requests the 20v from the usb source? Is that doable? It looks like I can pick them up on AliExpress. But I need a qualified adult to verify that’s what I need to do.
From there, would I be able to cord them with this method or would I need to build a better usb charger port?
Is there a better port to use? Usb-C is nice and small so I can fit it in wherever I like, but can it handle tool use? Would it be better to do usb or something else?


yes. Brace and bits, screwdriver, hammer + chisel, a few hand planes a few handsaws axe.
These tools’ biological battery power source can be easily re-charged on the go by inserting waste vegetable matter. Lubricate regularly with beer (or other fermented waste vegetable matter).
That’s what i mostly use; I’m dealing with wood mostly though - and of course i do it in order to pass time, not to make up rent, so slower is just fine for me.
Scythe is worth having just for the coolness of the word - unfortunately I don’t have any use for one. Adze would be another good one I’d like to find cheap and sharpen up.
But I’ll grant the power tools awkward situations like up a ladder, stretching over precariously, a battery drill one handed can be useful.’
I generally prefer fermented fruits and honey. Although I suppose rhubarb is a vegetable, and one of the things I grow with hand tools.
