Product quality is not good
Potentiometers don’t do incremental changes. Power LED doesn’t discharge. I don’t have a great experience.

Basura
No hace nada. El voltaje simplemente pasa. Los potenciómetros para ajustar el voltaje de salida no hacen nada, e incluso el interruptor que está etiquetado como ON/OFF no hace nada

Buck converter
Works as advertised. No issues with reducing voltage. Would bye again. Great product!

Great value and it works
Works great. A proprietary battery for a device I have died, so I used this attached to a big 12v DC battery to simulate the exact voltage and amperage that the broken battery provided and it works perfectly. Very good value for money.

I got a replacement that WORKS! 😄
First one sent to me was erratic and the adjusters did not work. After a few minutes of adjusting it started smoking. Requested a replacement and the replacement works! Feels like a score when you can get questionable to poor electronic quality from you know what country. I'm happy for the price. Expect duds if u can tolerate the hassle of exchanges.

Does not work
Does not work I bought one of these two power a high voltage motor and while I was testing the amps, I could not get the voltage to go up or down and when I measured the amps, it broke the light wouldn’t turn on. It wouldn’t produce volts or amps.
