I use these in quite a few projects
These step down regulators really work well. I have used them in both solar and industrial applications. The price is great and they provide a lot of value for the money. These little buck converters are super easy to install and very durable as well.

Works great!
If 24v is too much for your "clamps" this bad boy will step it down to 12v so your sensitives can handle it just fine!

Great for Starlink mini off 12v battery
Hooked up to 12v batteries in my van to run our Starlink mini. To avoid extra battery draw, add a switch between the fuse and converter so you can turn it off when not using the mini. This is oversized for my application and doesn’t heat up at all, even in its somewhat confined space.

Does A Fine Job But, Be Ready With A Small Screwdriver
This little box does what it says and does a fine job. Putting out 12.2 consistent volts from a 24 volt battery. Wiring was a challenge though, mainly due to the itty bitty, teeny weenie screws, and the micro space between the screw positions.

Works great
Works as it should bought this to help with using a 18v ryobi battery on my kayak for fish finder and charging my phonrs

12v to 5v. Yes.
Converts 12V to 5V for installation of Ring cameras on a solar barn. Been working well for approx. 6 month now.

Ideal for my Tesla that has a 16 volt lithium low voltage battery. Many devices can only accept 13.8 volts and overload at higher voltages. I incorporated this device into the cigarette lighter socket and it is brilliant. 10 amps runs my 35 watt mobile transceiver. Make sure to get at least the 10 amp version, if using this type of connection, and always have a fuse inline.

Used this to knock down the voltage of a small 24V solar panel to 12V. The solar panel is then hooked up to a 12V battery to keep it trickle charged. Worked great for my application.

Does exactly what's needed and seems to operate as advertised.

Bought this for the raspberry pi 5 and its not giving even the 5 amps the pi requires and this is supposed to be 10 amps. Very disappointed.
