Delinx2Pcs AC DC Converter Module Universal 110V 120V 220V 230V to DC 5V 12V Isolated Switching Power Supply Board (DC 12V 1A Version)

The item is in good quality and condition, as expected.

I took of the DC jack of an Arduino Uno R4, and soldered it in it's place, as it will go through the voltage regulator that way. Worked great. I wish it was easier to mount though, I 3D printed a mount so that I could put it in an enclosure with other components

this little thing is tiny! i mean 'tiny', which is kind of nice when your install room is limited.. i have it running two quiet pc fans in what was a too hot av receiver amp.. think of 3/4" x 1 3/8" x 1/2", and you will know that the soldering tabs will require a fine tipped iron to wire up... you will have problems if you are planning on using grandpa's 'old weller'.... safety is an issue with any unenclosed board, but since it is inside the amp enclosure i just placed it in a thick bed of hot melt glue... it works great and does what i needed it to...

I've used these power supplies before and found them excellent. They do not need lots of space and easily provide the power promised.

I used this in a panel build for a project. It supplies 5vdc to an Arduino, TFT touchscreen and to trigger an SSR (solid state relay).It's small but does the job with no heat output. A++

It may be to early to rate this converter before using it, but i noticed a lot of reviews complained about the two converters attached to each other. Mine did to, BUT they just snapped apart, very easily. All i did was wiggle them and it snapped apart. Maybe the manufacturer fixed the issue, at least mine were easy to break apart.
