Banggood

It works well, it has a good voltage elevation range, unfortunately there is no way to control the amperage. Tested with a lithium-ion battery with 3.8v, increasing the voltage to 12.50v.

For that little price is worth every penny.

должны работать

I have already one piece that works fine until now. This is my second piece and also work very well. I recommend it.

ottimo prodotto rapporto qualità prezzo

Funciona bien, pero la calidad o más bien dicho la atención que se presta al ensamblaje del producto, es muy mala. Cumple la función, pero vino mal ensamblado, con los capacitores o condensadores en distinta posición. Debido a que en donde se indica la entrada encontramos un capacitor de 50v y en donde se indica la salida, uno de 35v, lo cual debería ser inversamente.

Involucro di plastica antistatica sigillato. Ottimo assemblaggio dei componenti e comode scritte sul circuito stampato per identificare i terminali. Potenziometro multigiri per la regolazione della tensione di uscita.

This one is Good But It didn't work to down a voltage 12v to 30v work 12v to 5v didn't work

i couldn't believe you can step up voltage :) this is actually working low price, good work great bang good
