    Funciona bem, testei um com uma bateria 18650 e outro com duas em paralelo, perfeito, só recomendo cuidado no trimpot que faz saltos de voltagem complicados de se monitorar

    I have buy the item because it was very interesting but testing it I can not get the desired output. for example I have set output to 12v but just with a little load the voltage drop to 5-6volts. The output declared from banggood are not true/real for me.

    Nifty module that can charge LiIon battery and simultaneously provide 3.7-27v output for my many projects, great product!

    Fragile packaging, had no bubble plastic, too risky not to have damaged the parts.
