💡 HiLetgo 5pcs LM2596S-ADJ Power Module: Adjustable 3A DC-DC Buck Regulator for 5V/12V/24V Review

This power regulator has been a great addition to my automotive DIY projects. Through trial and error, I found that this adjustable module delivers consistent voltage, even when subjected to heavy loads. It has also been incredibly reliable during use. The only downside is that the size is a bit bulky, which can make installation challenging in tight spaces. Overall, I highly recommend this regulator for anyone looking for a solid power solution for their garage or shop.

I've lost count of how many Pis I've powered with this! You are so comfortable! Quite often I have, say, 12VDC, 19VDC or similar with no AC outlets and I want to put a Raspberry Pi in there. Just take one of these, set it to 5.1V with a voltmeter, THEN connect it to the Pi's 5V GPIO pins. Another good one! ATTENTION! DO NOT connect directly! Always set it with a voltmeter first. They come from the factory, are set very high, and will fry the Pi!

My old Engel had a non-digital thermostat so the knob position was a certain amount below the ambient temperature. It's not good if the temperature fluctuates around 30 degrees a day. The refrigerator is rated for 120V/24V/12V and the DC power supply ranges from 11.5V to 40V depending on the power input used. I could only find one digital thermostat labeled 12V and I needed one that could handle 12V to 40V so I bought these and placed one between the power supply and the thermostat. It worked…
