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

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

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

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.

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 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.
