Without current limiting its a disaster waiting to happen esp when using as a lithium pack charger

Cool idea, but you have a limited voltage range and no current control. It would be better idea to keep the original charger and hook up one of those buck/boost converters, then you'll have everything in the control and no danger of mains voltage.

dont forget the thumb nail, charging a 18650 cell at 12V+ and 8A, lmao.

Pro tip, if you random charge 12V lead acid batteries, charge them at 14.4V @ 10% total current rating with 2 diodes(rated fot 600V@10A) for reverse voltage protection, at a certain point of charging the battery will start to leak voltage back into the charger and overheat the charger or damage the charger. The diodes will get a bit warm but that's expected.

You have fallen for the common misconception that the thing you plug your phone or laptop into is a “charger”. It’s not. It’s a 5V or 19.2V power supply. The”charger” is in the phone or laptop. Adjusting the voltage doesn’t somehow magically turn it into a “charger”. It is simply a variable power supply.

nice job and good idea. I would have left the ferrite bead on the end of the cable for noise reduction. These switching supplies are very RF hostile.

This is just a variable voltage power supply. When you use this to charge your battery, if charging is completed, you have to disconnect the battery from this power supply immediately, becz this doesn't have auto cutoff, over voltage protection, reverse polarity protection.

extremely, theres loads of videos, just search convert atx psu into benchtop variable power supply. All these require a few extra components not typically sourced from household appliances. But you can make a super simple fixed voltage psu from an atx with the 12v, 5v, and 3v that comes from the box. Search that up if that's your fancy. Can source all but the screen in everything from alarm clocks to ghetto and busted blue tooth speakers. . But who needs an externally sourced screen of you have an extra voltmeter laying around. It also helps to purchase banana clips for easy connect and disconnect> ALSO If you have twp EXACT copies, I mean. Chip set and everything. You can parallel two atx to get a max of 24volts. if they aren't identical. You're going to run a major fire risk as the weaker of the two atx will be doing ALL the work
