How to increase the power of the charger 

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

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

😄😄 atleast you did it

1 year now still thinking to do it

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

Hi can you please tell me how to change a 5v 5amp power supply to 12-14v 5 amp? Would use it to run my cb radio. Thanks alot

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

Go to technical long channel it is his regular work

there are MANY problems with that

Hi im looking to do the same thing to run a cb radio at around 13v. Do you know how?

I do.... But i just like quality products

ha ha ha

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

@@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

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....

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

Then y u watch the video 😂

He already did it :)

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

@@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.

How much do you bet?

Hushhh, baje kotha

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.

@@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.

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.

Find a pin from the main ic that goes through a resistor to the output. Cut the trace, solder a trimmer potentiometer in there. Should get to 15/15.5v.

Chris Donuts - If a Chinese manufacturer can save 25 cents, on a million units, they can make an extra $250,000 profit. It’s not right, but that’s how it works. Most people don’t have the ability to check the device’s claimed output power, which means that the manufacturer can place anything on them. (Have you ever seen the rechargeable power banks, rated at 100,000 mAh? LOL) As long as people want cheap stuff, instead of quality stuff, China will keep making the cheap stuff. We’ll just keep throwing the broken ones into our landfills. After buying two or three cheap ones, you could have bought a good one, which will SAFELY provide the proper current, it will last for a long time and your phone will charge much faster. It makes me laugh, when people spend $800 on a phone, but won’t spend 10 or 15 dollars for a good charger. You’re also right about making sure that all components are within their operating range. This is very important, since most Chinese electronics are manufactured, right at the edge of their component’s specs. Then, you have to consider that most, if not all, of the semiconductors are counterfeit, which makes their ‘ratings’ worthless. Also, the person making this modification has to identify which specific components need upgrading, due to the increased current. This isn’t something that can be done by beginners, or an average hobbyist. This was an interesting video. It can help people learn how SMPS’s work, but it’s also a recipe for a house fire. Especially, if the person doing the modification, doesn’t take all of the above factors into account. Seriously, just buy a better charger. It’s also worth getting a basic USB tester, so that you can verify that you’re getting what you’re paying for. Consumers shouldn’t have to re-engineer their chargers, just so that they match the manufacturer’s claims.

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?
