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

Perfect tiny 120VAC to 5.18 VDC power supply. Quick shipping.

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.

Don't think you can beat these for the price. Make very sure you read the operational specs and know your load characteristics before you buy. These come with both units as a single unit that requires a bit of care when you separate them at the very tiny circuit board joints as this requires care and patients and a good tool with extremely small not aggressive saw teeth; don't recommend trying the use of a simple knife or box cutter as these things are very fragile and any slight error will destroy the soldering pads . Once in service this item can't be beat for the price in my opinion. I have been an Electrical Engineer since 1972 and my opinion is that for the price and effort these beat building your own from components, which is my usual method for a lot of years; just remember to stay withing the operating limits and don't recommend these in applications that require a lot of current regulation and ripple suppression.

Bought these to power Bluetooth adapters and they work great for that.

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.

I have ordered these multiple times and used a number of the 5v 2a power supply in IoT projects that needed an internal power supply (mostly ESP8266/ESP32 based). 2a is a bit overkill, but I have found these to reliable without taking too much space.

I like small things - but these are too flimsy for me to trust them with 120V. As others have pointed out, they come on a single board, but the break points are not done well, so you end up destroying one of them and with the traces so close it's impossible to get a safe design for the 120V in to work on the broken one. It's too small to test even - you'll have to put it into an assembly where it's safe before you can probe and test the supply before use.

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