🔌 Maxmoral 2pcs DC-DC Buck Converter Power Module: Efficient 3A Adjustable Step-Down LM2596 Voltage Regulator for Converting 24V to 12V, 5V, 3V Review

received quickly one of the two didn't work. Was returned quickly. The one that worked was good. I wanted to go from 12 volts to 5.20 volts and did the job. It doesn't have a meter so you must have a voltmeter to count

Used to step down a Li-ion battery to 3.05v for a cordless guitar battery that previously used 2 AA batteries. The fee is a bit higher than I was hoping for, but it still suits my use case. The light on the board even gave me a good idea of the battery charge level.

No matter how much power you put in, you'll get it. No matter how you turn the POT voltage, it never goes up or down. Of course it can't move very well past what you put in, but if you put 12.43 volts on and it stays at 11.65 volts no matter which way you turn the adjustment screw well, it tells me there is one poop is.

I bought this product to use with some of the older electric trains I am working on. Wanted to get a constant voltage for my train lighting (LED) and auxiliary motors from the variable track power. From the package and using jumpers I connected the device to my variable DC power supply. A few turns of the potentiometer and I got a stable 3 volt output from 3 to 20 volt input. Small enough that I can fit it almost anywhere, including some of the smaller HO trains I work on. Excellent value for…

At first I thought it was a problem with the power module as I couldn't change the output power. I finally figured out that the potentiometer needs to be turned more than 15 turns before the output voltage starts to change. I have a 24VDC power supply and the power module is set to 5.00VDC. After plugging in my Raspberry Pi, I checked the voltage again under load and it was still 5.00V DC. I was very happy to see that the voltage did not change under load. I've been using it for 1 month with no
