How to increase the power of the charger

[@sidyajv]

As an electronics enthusiasts i find your videos to be very informative and amazing. Such knowledge can only be gained through experience and im glad you share this with everyone. Thank you.

[@Inspironator]

Although many changes were needed, this video is educational by showing the approach and considerations to upgrade the power output of switching power supplies. Great video!

[@guillermosantana1565]

Thank you for sharing this information with us and your experience. I have read most of the comments from your followers and I tell you, that is very impressive. I am an electronics enthusiast and have very little experience learned much from it and will share the video. From the Dominican Republic Guillermo keep it up.

[@willyrivero470]

Excellent information. Just what I needed for experimenting. If you have more examples please show us. Thanks a lot!

[@shauryakrishna7084]

This channel shows me videos that I was searching for ages

[@RealOmarWahdan]

Finally Very clear and clean video. Thank you very interesting.

[@PaintmanJohn]

WOW. You taught an OLD DOG to RECYCLE junk he was about to put in the TRASH. EXCELLENT TUTORIAL.

[@casperel4everr]

Piece of cake, i did that step by step in a record time of 39 days. 🤣

[@iceberg789]

at least you did it in 39 days. some of my projects are going on for years.

[@power45118]

Yeah i did it with in 2-3 days didn't get any considerable output and burned the transistor further experimenting 🥺

[@recardothompson5960]

😄😄 atleast you did it

[@jeanedouar1971]

1 year now still thinking to do it

[@MCSGproject]

a lot of you may not understand, but this is a very quality video

[@eknaap8800]

But not a quality comment, without capitals and proper punctuation... Sad.

[@rhalfik]

I am a big fan of your work. You have a talent for design.

[@sincerelyyours7538]

Good video. As they say, the parts to make it costs pennies (usually), the knowledge to make it is priceless. In my case just finding the magnet wire to rewind the xfmr would cost many times simply replacing the ps with a bigger/better one but where would the knowledge come from? However, the safety concerns expressed in the comments are valid. Opening up and modifying any mains level electronic device is dangerous so don't do this unless you know and understand the risks. The shock you receive could be deadly!

[@sleepwalkerbg1]

Regards , Kasyan. Excellent channel. As your colleague , if you dont mind, i would add one precaution and warning - safety margins when winding SMPS transformer. In your video , i saw that you haven't left any space from end of winding to the end of transformer body. If you look closely , industrially made transformers have winding that is in wound in the middle of body ad have some space between ends. Sometimes they also use some insulating "sleeves" for ends of wire that connects to the transformer pins. That ensures better primary to secondary insulation and that can be dangerous from the safety point of view. Everything else is excellent , thank you for detail explanation , i really enjoy watching your videos. Keep up the good work.

[@alfieroseburg8887]

All your videos show your expertise on electronics and very valuable advise. Very clear videos and with diagrams. I think i will finally decide to try your template files so I could try Jlcpcb boards.

[@christophermontilla4748]

Good day. Is it also pssible to step down a 19volt laptop power brick to output 12volts just by modifying the windings. Without using any extra components such as a regulator.

[@gabrielM1111]

[@jesseisnoice3740]

Thanks, I can definitely do this at home 😭

[@thekef3013]

Its actually not that hard, but its still kinda pointless :D

[@whatitmeans]

It is possible to built or adapt this transformer circuits in a way that if nothing is connected as a Load, the whole circuit works as an open circuit for input stage??.. i mean, that if nothing is connected and the transformer still plugged, it stay there with zero power consumption

[@englishrupe01]

[@DimitriPappas]

Very interesting in principle! In practice however, a 2A 5V charger replacement could be purchased for less money than the time (=money) it would take to make this modification. Great knowledge for enthusiasts and engineers, though! Using the same principle, one could modify a much higher-amp PSU to an even higher output, thereby saving money! :)

[@JessicaRyan7of9]

Awesome. Would be nice to see you make a 5volt psu with 2.5amps please.

[@transgrl]

Cool video but for the effort you may as well just buy a suitable power supply in the first place

[@talclipse]

Your missing the point.. this is a fantastic video but you just can't see why it is..

[@transgrl]

@@talclipse no I understand that it's cool that you can change components of a plug for it to have a greater output of power but it's not worth it

[@keithking1985]

The idea is learning and the satisfaction you get from being able to do something like this... that guy was right you missed the point of the video....

[@transgrl]

@@keithking1985 the title says how to. This is supposed to be like a tutorial but you would just buy a better power supply.

[@GS-bd9zh]

Then y u watch the video 😂

[@Damjanhd]

I need opposite! To raise voltage from 12V to 24V, how to do that???

[@jessicaganser2982]

Just double the amount of turns on the autput and change the voltage of your Z diode to 22.8 v and make sure that the components on the output can handle the voltage. Im not sure but I think it is right.

[@mohimadvani6425]

very informative video. 👍👍

[@MCsCreations]

Really interesting, man! 😃 Great job!!!

[@sidyajv]

Can you demonstrate with explanation how can we turn a PC SMPS to a variable power supply.

[@TheJavaSync]

[@jussapitka6041]

I bet the components are already driven above their specifications, and this is doing it even more.

[@thekaiser4333]

How much do you bet?

[@GlynWilliams1950]

Great video. Thanks for the detailed explanation

[@DaunTalasChanel]

Thanks

[@robozstarrr8930]

interesting, would have been nice to know the AC input voltage applied during the initial output analysis and upon completion how it performed over the entire input AC voltage range.... not to mention temperature rise of key components ( before and after )... Cheers

[@frantickoala994]

Based on the plug I'm going to go out on a limb and say 220 to 240 volts would be the input. Tbe plug type is type C which is European Asia South America ungrounded

[@robozstarrr8930]

@@frantickoala994 thxs, kinda figured that, the label on the power supply listed input Voltage: 100 to 240 V AC. normally when you measure an output voltage one states at what input voltage. it's also a good idea ( & design testing ) to measure the output ( range ) over the entire input (range) as there will be some variation . . . and especially after any modification(s) have been made.

[@californiakayaker]

@Kasyan TV What is the micro socket on that tester for ?

[@opinair]

Good job

[@gabrielM1111]

You have to be crazy to do all this work when you can buy what you made for $5. What would be interesting is to know how to change a 5v 5amp power supply to 12v 5amp

Worth learning the structure and funtionality of the adaptor, but never recommended to fix the components just because of the danger

[@CristianDiPuorto_glockshock]

Incredible how cheap chinese manufacturers are. Slightly higher quality components cannot cost that much more and performance gains are amazing. Have you checked if all the components are within their power rating range? What about temps?

[@bkahlerventer]

Chris Donuts, all manufacturers do this cutting costs on components. I work on retro computers from the 80s out of the US such as commodore 64 etc. You must see the cost cutting there. Going into the history of commodore business machines, the cost cutting is very core to the heart of commercial electronics as consumers view electronics as luxuries. Wallwarts tend to be cheap and fail. When they do, you buy another cheap one to replace it. Problem is where do you stop cutting costs and make it durable?

[@animarkzero]

The question is if the Power-Transistor can withstand the higher current without cooling?

[@keithking1985]

The answer is no it wont!! That's what I thought too. And usually this channel would have pointed this out but they didn't. I wonder if they just missed it....

[@kalashnikov_47z]

Please do same thing With 36V 10A Powersupply Increase voltage/ increase current 😅

[@anindyamitra5091]

I don't like this topology as it often fails, you can't tell when it fails. And this kind of power supplies must not be used to charge any mobile device, its insulations are as unreliable as its price. Many death cases can be found, associated with it. They must be banned for being used as a charger. Anyway I appreciated your modification on this thing.

[@somedude2492]

These are switching PSUs. They are insulated from the line by the transformer. Inside the case, they are perfectly insulated. Don't go scare random people on the internet please.

[@anindyamitra5091]

@@somedude2492, I don't need to scare anybody, everyone has their own intelligence to judge which is correct. I have worked with this kind of stuffs, and this kind of power supplies (using one MAIN switching transistor) can often fail, excluding rare occasions. I have also opened the transformer myself and saw that it doesn't have more than one layer of insulation tape between primary/auxiliary and secondary winding. And the insulation too isn't a proper kapton tape. And everything isn't insulated. Metal-body smartphones are also available in the market that has a common ground connected directly (galvanically) to the external metal body, which may lead to shock if the 0.5mm thin insulation in the transformer or the 1nF 1kV capacitor in the charger fails for some reason. If you don't believe me, you don't have to, go check out DiodeGoneWild 's youtube channel or bigclivedotcom 's youtube channel. They have explained everything practically. Please do some research before criticising someone. After that if you can prove me wrong, I will withdraw my words from the comment section.
