Good explanation. If you just need to test laptops, you could buy the universal adapter that goes with those barrel jacks. Still, the power supply can be useful for many other things, so it all depends on one's needs.
IMO, this is far more useful, given that it can run anything from an 8.5v Chromebook to a 20v ThinkPad, with enough power for a higher-amperage gaming machine. It's just generally more versatile.
@Dodoid True. Some machines are picky, especially Dell laptops. My Precision M6400 might run from a 65 watt universal adapter, but the performance will definitely be throttled (and the computer will certainly complain). How much wattage could that bench supply put out?
Unfortunately, the MacBook still doesn't work. I haven't had all that much time to get back to it, but what further diagnostics I have done haven't really told me anything other than "SMC's gone weird". As for what's actually causing it, I haven't a clue. Power supply wise, just look around and buy something that suits your needs. Do keep in mind that some beefier laptops (for example, an ASUS gaming laptop I used to have) will draw quite a lot of power, so a larger power supply capable of supplying more amps can be rather useful.
If you'd like to do this, and don't already have connector tips, I recommend you get this pack, as it includes the cable, AND has some of the more exotic connectors for stuff like older Samsung laptops, and especially the 3 and 4 pin connectors for the Latitude C Series and ThinkPad 760 series respectively! www.dx.com/p/replacement-power-cable-with-11-12-adapters-for-laptop-notebook-129303
I made a diy universal laptop charger by using a universal connector from Walmart for small gadgets that have laptop connectors and took a laptop charger and a charging port it works in, then I solder the Walmart connector to the charging port and connect it to my old laptops charger to use many other laptops including my old one

where do you get voltage, ampereage and polarity if not on laptop?
What’s a good bench power supply on a budget that’s adjustable? And did you find out what’s wrong with the MacBook in your MacBook repair vid?

How connect Dc jack data wire
actually the voltage does not matter that much 12-20 volts is ok, the laptop self adjust to the provided voltage
Where do you get the barrel jack set from?

It sounds better today
