Excelente explicacion, gracias y felicitaciones

[@maninlauriano6422]

Um dia vou enteder
Parabés

[@Ansarimasoom0009]

Bhai mobile charge ho jaye ga nhi

[@user-ed4zg4xe3v]

❤

[@sivashankar5206]

Base & emitter connection wrong connection to be changed in opposite directions instead of diagram shown

[@tgorafa]

Aunque le ponga el doblador de media onda nunca podrá obtener más de 5watts que es la potencia original del transformador.....5vol x 1 amp

[@sharbanthakur7220]

I can use bd139 and bd140

[@roomengineer]

Yes for sure 👍

[@gamingwithpavan7942]

Bro in same way make the inverter from 5v to 110v or 220v 150 watt

[@vothanh7717]

Chiều điốt và tụ hoá đấu sao?

[@sharbanthakur7220]

I can use 13005a and mbr 204þ

[@omkarpatade8795]

Mobile charging hota hai kya

[@sahebsakshit4052]

Sir circuit diagram Di ji ye please

[@naveednaveedu2314]

Battery charging add

[@daikelperezdecorcho2675]

El circuito me da 180v de salida, coloqué un cargador de móvil y no funciona. Cómo puedo ajustarlo a 120v?

[@mikejbhartiya]

Use AC capacitor instead of two 10u/220v . There may be one 104j/440v AC capacitor work perfectly. 👌

[@rafinmashrafi2855]

How many hours it can glow a led light

[@roomengineer]

15 to 20 minutes in single 18650 battery its depend on battery mah. You can add 2 or 3 battery in parallel for more backup and also add heatsink on transistor.

[@asshishir7112]

Bro.. 33 ohm resistor Can be fitted...... Plz... Tell me

[@roomengineer]

yes, it will work perfectly.👍

[@asshishir7112]

Brother I want to talk to you. How to talk .. . Plz.. Tell me.

[@muhammadyasyen3180]

How many volts does the circuit output? How many hours does the battery last if you charge the phone only?

[@roomengineer]

This circuit will give only 110v 20w output. Connect more battery in parallel for more backup.

[@sunnysam2894]

Can i use 12v input in this project??

[@roomengineer]

No, this circuit work with 4v to 5v only. You can use more battery in parallel for more backup.

[@EE_L_SudeepGanguly]

8:47 Does it really work ????

[@subhajitsamanta612]

yes, it works. I tried it but its glow is very low and low backup, use 2 or 3 battery in parallel and use a MOSFET(IRFZ44N)
instead of D882 n-p-n transistor & don't forget to use a heat sink, after changing these components I got better result, i.e., it lit up my study room sufficiently for 1 & half hour. 👍

[@subhajitsamanta612]

@Hamza Shahid No, I'm talking about this circuit. This circuit is right but when I tried it, I saw that one 3.7V li battery does not provide so much power to light up a 9W led sufficiently. So, using 2 or 3 battery in parallel will give you more current that will power the led sufficiently and when high current flows in your circuit, you need power transistor(e.g, TIP41,2N3035,BD882,MJE13003 etc.) or MOSFETs but different transistor has different frequencies. So, you should use D882/MJE13003/MJE13005 transistor.

[@subhajitsamanta612]

@Hamza Shahid I used IRFZ44n as it was available to me, I recommend you A MJE13003/MJE13005 transistor with a heat sink, you easily find it in a old mosquito bat and if you don't have an option and D882 transistor (shown in the above video) is available to you, use it with a big heat sink, it will do your work. Thanks!!

[@subhajitsamanta612]

@Hamza Shahid Ok, then this circuit will easily do your work. When n-p-n transistor or n-channel MOSFET is used for switching then connection is like this [ base of BJT = gate of MOSFET, emitter of BJT = source of MOSFET, collector of BJT = drain of MOSFET]. yes, middle pin or drain points to ground. But in this case, you have to connect one end of transformer to gate of MOSFET, another end of transformer to drain or middle pin and connect ground to 3rd pin or source. Keep up with electronics !!
