Very good video and easy to understand right to the point. you would make a great teacher and your multimeter is awesome. but I must say the most impressive part of the video was in the beginning when you opened the retaining clips with your fist somehow. I always fight with those to open and usually damage the case with a screwdriver doing so thank you and cheers from canada

Emeğinize sağlık efendim. Allah CC sizi her zaman hedeflerinize ulaştırır. İnşallah.

Another excellent video. I think the customer would be very happy. In many countries the user would just throw the charger away and buy a new one.
