nicely done. some more explanation of the comparator....but we can figure that out. Thanks

[@Electricquantism402]

Thanks 👍👍

[@mountris7can]

My adapter has an IC with six legs,not the same(its so tiny that specifications dont even exist),what do I do in this case,how shall I detect the resistor to pull out??..Nice video and work by the way..thank you in advance

@@Electricquantism402 I dont even know..but the coupler on the other side of the board writes on it: "EL 817 C024",if thats a useful clue...

[@arishimran2206]

Why did you choose resisters in series and left other

[@Electricquantism402]

Mentioned that its directly connected to inverting input pin which controls the feedback depending upon its resistance between output and inverting input pin..

[@arishimran2206]

@Electricquantism402 and wasn't connection of single resistance the same

[@JPAG0806]

👍👍but: How to open such a sealed housing without damaging......

[@Electricquantism402]

Apply thinner and wait for a while, then open.
Or use small hammer and smash from all sides by placing the housing on floor..

[@KapilDahiya-dc2uw]

Ampier loss 😢 so only voltage

[@XS1GOLIATH1]

Will it give the same ampere as before after converting it? If it was a 19 v 3A default will it still give 15v 3A after converting?

[@Electricquantism402]

For compensation of 65w power, it increases the current when voltage is decreased.

[@XS1GOLIATH1]

@@Electricquantism402 even better, hope it won't over work the switching driver. But yeah Thank you for that.
Looking forward for more videos in your channel.

[@ElectronicBlood]

I have many of them

[@Electricquantism402]

Good.. enjoy by converting them.👍👍

[@lucvorstenbosch7938]

Hello, I have a strange problem with modification of the adapter. I can make the voltage adjustable but when I touch the metal of the potentiometer the voltage goes to zero and I have to restart the adapter. It happens each time. When I try to use different potmeter or resistance the adapter will try to start but stops directly.

[@Electricquantism402]

Which IC is in your adapter?

[@LP-yd4ww]

Resistor is ?? Kohm.

[@Electricquantism402]

Yes..8.06Kohm which is default resistor.

[@MonkeyBlueAss]

removed resistor in 8.06Kohm and the new resistor is 1k in series with the potentiometer
