    To be honest, didn't try it yet, but I believe that's good, while looking at good quality pcb. 1.30e per piece is really ok price.

    Very fast delivery that step-down module does what it's supposed to do.

    Do not expect to have 3A (as advertised) at the output of this module or at 3.5V, before ... the fusion, (module at 90 ° in one minute). effective up to 2.5A and again with a voltage of 4.75V and still a high temperature. Continuous test at 2A, with a permissible module temperature, it works but still at 4.8V, which is close to the low limit allowed by USB standards (4.75V) ... Voltage stable output between 8 and 22V input (I was not higher). The yield is ~ 75%.

    These seem well built and preform as described however 1.5 amp is about the limit. At 1+ amp draw they get hot to touch! I mounted several modules to an aluminum heat sink which made them run much cooler and they will likely last much longer. Great product just beware of its limitations.

    Modulo di alimentazione molto compatto e funzionale. Buona la corrente erogata particolarmente adatto per progetti che necessitano di una sorgete con range di tensione variabile ma alimentazione stabilizzata a 5V 1.5÷2A.

    Good product, excellent for battery operated applications that require usb power as well. Output is stable 5v, no hum or ripple so all good.

    It is working as expected. I have connected five of these in parallel to a 12v power supply.
