The Sticker says 2.0mA 😂 nice china quality

I only needed to replaced that +ive side 75K resistor with 100K pot... and viola now I'm getting 24V from a 19V supply... Thanks a bunch. 😁

The circuit lay out fir the project is always helpful for construction of the project. Kindly add the circuit diagram. Vdo instructions are not enough to notice the exact modifications.

[popepaul]

Very useful for me as I am a novice at Electronics I don’t think anybody is showing the sort of hacks keep up the good work look forward to the next one and hi from the UK

[shubhagar]

I think u have a deep knowledge of pcb board, , i can't make such changes without knowing, , is there any way learn how...?

[neelkanthkalgaonkar]

You have not mentioned rating of output capacitors. Out of originals, one is of 1000 mf and the other of 470 mf. You are replacing one as 470 mf and other as 220 mf. You are silent on values of them. You will agree that the value matters significantly. Similarly you are silent on the max. rating amperage capacity we can get from 3.0 v to 24 v subsequent to modification. If possible please clarify on these points.

initially the adapter sticker says it 2mA, after upgrades you can't shows how many amps are supplied?

Welp, awesome vid as usual mate, but here's a little tip: if you're gonna use loud background music, but speak with a really low voice, a better alternative would be to simply not talk and write down the things you are doing in the video.
Otherwise great job as usual. Cheers.

Boa noite e obrigado pelo vídeo bem explicado. Se eu quiser pôr a voltagem mínima em 1, 5v, teria que mudar algum componente interno que é a referência? quanto ao último resistor introduzido ao circuito, não entendi onde foi colocado e qual o valor dele. Se puder tirar-me a dúvida...Obrigado desde já e forte abraço do Brasil.

Nice work, but if its rated for 12v 2amp, and you crank the voltage without limiting the amp output accordingly you risk of burning out the circuit no?

[mdriyasatali]

Par kya isme AMP me koi frk padega ???

[lebronmalakas]

This is legit!i try it and i realize im never need buck converter now! 😊

Edited
I try multiturn trimmer and its the best potentiometer for slowly moving of voltage 100k is value
19v adaptor playing around 2v to 30v

[RinksRides]

This is great! As I literally have a small mountain of these in my basement

[techie]

Good work... But where to get lcd display?link plz

[Terrestrial..]

Voltage regulators don't work with modern electronic light bulbs, only the older types as they require a set Voltage to run.

[thenarrowgate]

Nifty idea but is it really safe if onesn using it constantly at 24 volts say?

[veko]

Buen video 👍 pero el enlace Dropbox no funciona me parece. Que agregaste un resistor en paralelo al resistor a tierra

[robert]

Sorry, but this will work only with that particular adaptor that you are testing on.

[vinayakbhamare]

Can we get such type of digital charger. Please tell. Also mention rate too.
