12V to 5V Mobile usb charger using any power transistor
HTML-код
- Опубликовано: 5 сен 2024
- Hello friends, today in this video i have shown how to make a simple mobile phone charger with using any power transistor and a 5.1V zener. Then you can supply this circuit from any 9V -12V battery or even any 12V car battery. If you are planning to input above 12v then put a bigger heatsink for the transistor.
Components required for this project:-
Tip41 transistor (any power transistor)
470 ohm resistor
47uf capacitor
5.1V zener
Heatsink
Usb female port connector
9V to 12V battery

Thank you for watching.
Is this functional and already tested?how many Amperes/Current is the output of this?
Bravo, finalmente una persona che fa notare con chiarezza quello che fà, dando anche le dimostrazioni di quello che ha effettuato.
Your project idea is great. But the problem with this circuit is it's series voltage regulator. Such circuit is not very efficient and is loosing a lot of energy as heat. As such circuits are used normally with 12V batteries which are limited in power. So the best idea is to use a switching regulator instead of series regulator. I will soon upload a video on such switching regulator. best wishes and keep the nice work up. Regards,
Just use a step down converter problem solved
@@RakshithPrakash You are right but charger have some other characteristics also on of them is constant current supply. also step down converter is not cheap. They are expensive some times.
@@RakshithPrakash 2596?
@@RakshithPrakash is it healthy....?
Sometimes we have the material to assemble but we do not see the idea that other applications may even have. I like it, congratulations !!!
Awesome idea and great project. Keep the nice work up. Best regards,
Hii bhai
This circuit has some serious drawbacks. A) No current limit B) Overheating due to lack of heatsink, exposing the transistor to thermal breakdown C) In case the transistor gets shorted, the full 12V supply will be the input to the phone charging system. This means immediate death of it. In general, this is a primitive "emmitter follower" circuit inappropriate for such an application. It would be much better if a 7805 stabiliser was used and due to the permanent danger of short circuit of the series transistor within the regulator, it would be much safer to use first a 7808 as a preregulator and then a 7805 after that one. In this way, the necessary power drop transformed in heat will be better shared between the two regulators. Again, a heat sink is necessary for both of them. The best way is to use a transformer type dc to dc converter, especially as regards safe operation. Buck converters are not safe in this respect. (Same effect as above if the switching transistor fails getting shorted).
Wow
....very usefull comments.
.thank you today I got a new idea
You just need a voltage regulator/reductor (Lm7805), one component only
Some things are not clear in the video, I didn't see how the capacitor was connected, you even instructed that heat sink should be used, everything supposed to be shown, I think. You really tried, please improve on the teaching
. जो बनाया उस में 4 पॉइंट ऊपर वोल्टेज 4 पॉइंट से है और एंड्राइड मोबाइल को 5 वोल्टेज चाहिए तो यह चार्ज नहीं होगा दिखा रहा है लेकिन चार्ज नहीं कृपया इसे बताएं ताकि 5 वोल्टेज पूरा मिले
Output voltage 5 but how is the ampere please
what capasitor use 22uf not seen this vedio
Thank you for this idea.
Thank you for idea
Isnt it better if the z-diode is parallel to the usb instead of parallel to the serial connection of the usb and the transistor? In this case you wouldnt loose 0,2V due to the transistor.
I'm not an expert so i dont want to teach someone. I'm just curious.
The diode is very limited in current
I just saw it, it was amazing.. :) 👍
Achha kam karega ah
*you don't see us where you connected the capacitor on the video. WHY?*
Hi is it possible to do 3.7v to 1.2v
Current acumulator...... Ampere sir?
Super
Can I ask if it is the same with 4 pins USB port?
Mhon intruksinya lur...itu tip/TR,nya panasnya apa ngk over ya bos...smntra sy pkai 78xx tanpa elco panasnya lumayan panas juga...klu lama2 bisa shot
Good👍
Bhai kya isse ic hit nahi hogi ...kya isko koi bi 12v ki supply de to chalega ..isse mobaile to kharab nahi hoga na ...
What is the output current?. If need 1.5 Amps output current what modification need in this circuit?
Channel bale baba kya achha kam karta hai ah bana skate hai mobile par koi effect to nhi padega
Use ic 7805
The circuit charges the mobile but the MOSFET gets very hot in only 10 sec.
amazing
Thanks
This one is legit I did a project hydroelectric everything work perfectly
What's the music.?
Dear inventor, it that systems is possible to charged automatically the Power source 12v battery 15amp, No stop to working 24 hours, to be free Energy. It that possible ? please do a video let us seen . ..
Z44n MOSFET se banasakte he kya
Ampere
wowww.. thx for idea, Why you did not just use LM7805 to convert from 12 v to 5 v sir?
I am making it in my video, but the regulator 7805 really hot when connected to phone. could you help me sir?
listen this conversation.. same problem
Yes, this is a liner regulator.
Regulate voltage producing Lot's of heat. Install a good heatsink for the ic
@@TechIdeasAGI have install the heatsink, but it still hot. like an iron for my clothes.. do you have any suggestion to flow the current from battery and voltage regulate by 7805? thx before
I have bd140, can I use this to flow the current from batt
Heatsink is necessary.The transistor will get hot.
DC charger Apne banaa to Diya lekin usmein charging badhega ya nahin
Can I use 13005 transistor???
How much is the maximum current in output
Thank you
How many ahmpere output in this circuit?
And which no. Transistor you use in this circuit?
And this is safe circuit for bike battery?
6volt battery ai circuit use korte pari ki?
Love stuff like this.....your vid shows a 22uf cap, but your description says a 47uf cap, which is it ? does it matter? also, my
female usb port was taken from a board, and has 4 pins...how would i know which is positive ? thanks, keep those vids coming please....
Middle two pins are for usb andfor the polarity you have to check it manually
@@TechIdeasAG Does the capacitance matter?
@@kassimnazeer3690 yes that matters
hi what happen if you use a 5v cellphone charger to plug a pc 12v fan, will it work normally or slower
Yes , will run slower
Capacitor ko kis me connect kar na hai
สุดยอดเลยครับ
Mobile ki battary fulyge
Kitne ampiar ka hai sir.?
Sir ye kitne amp nikae ga surkit
music name pls
Some things are not clear in the video, I didn't see how the capacitor was connected, you even instructed that heat sink should be used, everything supposed to be shown, I think. You really tried, please improve the teaching
Capacitor goes between the output of the DC 5 Volt, Electrolytic capacitor is Polarity sensitive not the black strip lead on the capacitor is the negative, it should be connected to the negative of the 5V output, Transistor will dissipate heat so in order to not burn it up or make it too hot put a heatsink on it, you can get them online, it goes on the metal part of the transistor. That is all. I did not make this video, but I am a hobbyist in Electronics and I can help. Comment back to me if you have any further questions.
Sir can I use 7805 instead of tip 41…
7805 jal jata hai. Mobail swaha hone ka khatra hai
yeah
A posição ( polarização) do capacitor?
Mạch này tôi làm qua rồi. Hiệu suất kém. Tip 41 nóng lắn. Ngốn điện ắc quy lắm
47uf me 63 voltage ka capacitor laga sakte hai kya please reply
Yes, ofcourse
Transistor 908 ka hai chalega
Kitna amp ka hai charger
The transistor is going to overheat and burnout
You don’t show how you connect the capacitor
The output is 10volt
phone go boom
Video main 22 uf or video ke niche likha hai 47 uf
It will not charge the phone
Bcoz its less than 5v
Chargers generally output 5.1/5.2 vdc
And u have not shown ampere reading
Must be atleast ,2 amps per hour
It's work solar panel
What was the use zener diode plz
Study zener diode on the internet. This only releases the 5 volts for the cell phone.
how much Amper 500mA. ???????
It depends on the transistor
what one would need to have more than 2 Amps or more for fast charging
Then use 3055 transistor
@@TechIdeasAG ok thx good joob
O meu continuar saindo 12 v
Just Buy Buck Converter and you're done.
Biasa nya pakai ic 7805
Olá amigo parabéns pelos vídeos, me ajude como posso fazer um dispositivo simples para descarregar as baterias de LIPO usadas em drones
Where is the capasitor 22uf
1:52 blind are you
👏👏👏👏👏👏👍👍👍👍👍
Or jo ic itna heat ho jata os ka solution....
Why is it that the final voltage of my work is higher? I have reached 5.6v🤕😢
Use lm317 🤔🤔
Amigos les quierondecir que no valeee. En si si funciona perooo reeecaliennnntaaaaa fuerteeeeee yo lo a una moto ya que queria instalar para cargar mi celular pero recalienta exesivamente le puse un disipador igual calienta le puse como hacen con dos condenzadores e igual manera recalienta mucho sii carga solo que recalienta fuertisimo y da la señal de que quisiera explotar. Una desepcion mejor comprarse un cenicero o adaptador para colocarle un chupon que venden para cargar en el carro eso si funciona, para mi eso es mejor que estos siperder el tiempo haciendo estas cosas
7805 ic 5v UBS
Chat chat 3Ma ear
Paano malalaman kong 5v or 6v
चुटिया किसी और को बनाना 7806 सिर्फ 5 वोल्ट निकलता है मोबाइल चार्जिंग सिर्फ दिखाएगा लेकिन चार्ज नहीं होगा चार्जिंग के लिए 1 Amp चाहिए 7806 सिर्फ 5 वोल्ट निकलता है मोबाइल चार्जिंग दिखायेगा लेकिन मोबाइल चार्जिंग नहीं होगा
Transistor tip41 kis chees ko todne par milega sir?
