arrived very early. packaged well, works as expected as you can see from pics I had 12.2volts input and had 5volts output, I will use this for a power bank I’m working on, happy so far.

el circuito regula bastante bien la tensión de 12v a 5v.

I have used this to power PAM based amps without a problem, don't forget to add an inline smoothing capacitor between audio circuits for a better sound. It's powered other 5v devices no problem as well. Great DC-DC Regulator with a huge range of voltage inputs.
