Fitst thank you for sharing your knowledge. I really appreciate it 🙏🏼 Question: I live in Mexico (127VAC) and SMPS was switched to 220V (insted of 110V) so it get damaged during working for some time. Now is making a buzzing sound and switching on and off. Is this a similar damage?

Peace be upon you. I have the same power supply, but it makes a buzzing sound and the output voltage is 16. There is no control over the variable resistor, and when loaded, the voltage drops. What is the reason?

Yo my main man Has! Has tell me, have you ever tinkered in upgrading 110v powertool chargers to 220v? I'm getting so tired of carrying around extra step down transformers because the cordless drills (for some weird reason) are always way cheaper in 110v! I have saved up for some Makita and Metabo HPT tools for jobsite BUT carrying around extra transformers is always a pain.

10:55 Sir, please don't teach us to regulate the output voltage WITHOUT any load. As you know, a lot of power supplies output higher voltage on idle, and then it drops to correct value when you apply the load.
