Hi friend thanks for the informative series. I truly learned a lot and appreciate what you are doing

Good day Haseeb, the easiest way to open the charger is by applying a small amount of petrol / gasoline with a cotton tip to the plastic seam (where you put the screwdriver) going around the charger. It would come apart in less than 3 to 5 minutes with no damage to the case. To stick it back you can use B7000 glue...I have opened a few chargers like this...regards

Hello, I love your videos, why do you use a Series Lamp, does it have to be Incadescent?

Thank you for your video. Can you please explain ( at 1:46 ) why 333V on cappacitor means the cappacitor is just only rectifying voltage? And what leakage must be so that the transistor can be considered as faulty.

Thank you so much in creating your videos, it has helped lots of people including me. I am writing to you if you could make a video of LTC3865 a dual synchronous step-down DC/DC switching regulator explaining in detail all the functions of each pins, what voltages currents should be there and what causes the Run pins, TK/SS to shut down. Thank you

Hello sir, I have a question, With the power supply on,why does the mosfet burn when I measure the voltage between the gate and minus after bridge with the voltmeter?😭😭😭I burned 3 mosfets and the resistors in the drain.

Not sure how you found that transistor was faulty? Diode reading was 0.7 at worst case? In circuit? Please explain if you have time. Thanks!

Just dip a piece of cotton in petrol and apply all along the gap between the two tops and wait just for 2 minutes it will separate by just applying small force no need to fight with it to open it😂😂😂😂
