An excellent product, small in size and powerful enough. One goes to charge the battery and the other to power the LED module. Recommend.

Works great, good value, but be carefull not to reverse power the unit (having the power supply plugged on the module and the battery at the other end, and unplugged the charger). The current flowing from the battery back to the charger ruined the IC on one of my modules... I bough replacement ICs (cheaper than the complete module). I added a N Mosfet on the output +, the gate being connected to the input +. The it is blocked when input voltage is less than V_battery+Vth and avoid reverse current damages.

Conversor de tensão DC com ajuste de corrente para ser usados em fontes de alimentação ou como carregadores de baterias de excelente qualidade com indicadores a base LEDs a fim de monitorar sobre corrente e tensão. Eu o recomendo!

great product. stable output, low noise, even under load. (I use it as milliohmmeter - it reaches even resistance values till 1mohm @ 1A (used a professional milliohmmeter as reference) (this means that the voltage goes down to 1mV not just 1.25V as seen in the datasheet))

Das Produkt war wie beschrieben. Ich habe es mit einer elektronischen Ladung getestet und es funktioniert einwandfrei für meine Bedürfnisse.

Product was as described. I've tested it with an electronic load and it's working fine for my needs.
