Delinx 2Pcs AC DC Converter Module Universal 110V 120V 220V 230V to DC 5V 12V Isolated Switching Power Supply Board (DC 5V 2A Version)

Used this in an old intercom system to provide bluetooth thru the aux input. This little converter fit nicely inside the cabinet, attached with some velcro. It is quite small and light. Left it on for hours and ho issues with heat. 110V draw is nominal so was able to use 18 gauge wire from 110 source to this. Cut an old USB cable to provide power to bluetooth. Probably 20 gauge. Holes for wires are quite small, but what I used fit fine. Anything bigger may be an issue. Or you could use a push on connector. Yes, you get two of them that need to be separated. Just used my dremel with a thin abrasive blade to score the seam and then snapped apart. Easy peasy. I'm sure you could do the same with a sharp knife. There appear to be no electronics of traces in the area you need to cut.

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...

They are so far working well for my use. Compact, very little heat and a good 12.14 volts give or take on the output side with a steady 120 volts input. Am basically using as fan drivers and or lighting for bench tools such as solder station fume fan and so on. Only draw back to these is no repeat no mounting holes and basically require clips or something equivalent to mount them. I got glued the edges a piece of insulating substrate which was hot glued in place. They work. Very nice build quality. Only 4 stars until I see how long they hold up. One is cooled and the other open air in cased. Really don't believe these will have any problems.

These are small. I was able to fit two of them in a 2.4"W x 2.2"H x 1.3"D box. Hot glued down. AC voltage in, and two sets of 5V out for two USB ports for charging. Neat little boards, and a neat little project. Put them on a guitar pedal board because somebody always needs to charge their damn phone or tablet on stage.

Really nice and well built with what looks to be top notch materials, i really like these for my projects.

Perfect for its small size and its performance. I am using it to power a NodeMCU/8266 board from the mains and it just works...5VDC out as needed. The solder tabs provided a convenient attachment for wires. I am counting on the NodeMCU board's in line capacitor to smooth the output a bit...no problem. The ultra small form factor prevents it having any convenient way to mount it to a surface...wound up hot-gluing it in place...not pretty but it works. The component leads are a bit too long and must be cut off to use the underside of the PC for mounting.

I used these 4.2 volt converters to power two of my old under the counter battery LED units. These units turned the LEDs on and off when it sensed movement. The LEDs worked with 4.5 volts from six AA batteries connected in parallel. These batteries had to be changed too often as the system drained them very fast. The converters fitted perfectly inside the LEDs case and the units work as new. The converters are not heating up and are performing as expected. All for the price of one set of AA batteries!!!.

Works as advertised but delivered whenever they fell like it.

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

used to to directly connect a 5v eufyCam security camera to 220v line using a DIY switch plate. Works like it supposed to.

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

It powers my Blink camera from the porch light. I connected a USB-C cable from the mini power supply to the camera and 'Bingo'.

These little rectifier buck converters work great! As adveratized.
