Buck Converter, Icstation DC 5-23V to 0-16.5V Adjustable Voltage Regulator Buck Boost Converter Setp Down Power Supply Module

I got this too use as a bench power supply for small electronics projects. These projects don't require a precision instrument, so this tiny unit fills the bill perfectly.The case is a little tricky to assemble. The six pieces plus two buttons have to be aligned correctly with tabs inserted and then held together with two screws. If you have trouble getting the pieces to stay together, some painter's tape will work to keep things in place until you get the screws in.One of the buttons was too large to fit through the hole in the case. I was able to file it down to fit in a couple of minutes.I used a 19 volt power supply from an old laptop. I cut the barrel connector off, stripped the wires and tinned the ends with a soldering iron. They were a bit too thick to fit in the connectors, but crimping them with pliers fixed the problem.As can be seen in the photos, the output voltage runs a bit higher than indicated on the screen. This is inconsequential for my projects, but if necessary, you can hook the power supply up to a meter and adjust to offset to the exact voltage.Great product, at an excellent price. Just for grins I added a photo of the computer power supply and adapter this unit replaces. At about 5% of the size and weight, my workbench is much happier.

I read some other reviews that the voltage was off and it was difficult to assemble...I didn’t experience either of these things. I checked the output voltage with my voltmeter and it was .01v off around 5 and was .03 off around 10. I used a small power supply for like a laptop or something similar. Works very well for what I needed it for.

I tried this to step down a 12v external battery to 8.5v to run a camera and it works great! Very easy to set, however, I've had 1 camera almost get fried because the voltage got reset back up to 12v. I'm looking for a way to lock off the voltage adjustment buttons to make sure I'm not in the middle of a shoot and it kills my camera.Also, be aware that if you want to step down to 8.5v and you battery has 9v, 12v settings, you have to use the 12v setting because the regulator can only go +1v down from the input voltage or more. So the 9v will only go down to 8v.I was just not comfortable with setting the power source to 12v and dissipating that much voltage.

I even search by the number on google, but no instructions available. And the voltage input is too low !!

I'm using this to fix a badly designed USB-C to MagSafe adapter cable, adding the needed voltage regulation inline to bring it down from 20VDC to 16.5. It works, but I'm going to have to remove the connectors and solder wires to the board permanently, because I just can't seem to get the screw terminals to secure the wires well enough that I don't get short circuits and sparks.The problem with this design is that the screw-down connectors are way, way too close together. So it's really easy for an unjacketed ground wire to flex enough to touch a stray strand that's bunched up slightly, resulting in fireworks.Fortunately, the product seems to have a self-resetting fuse, but it would still be better if this product had either banana plugs or 2.5mm DC plugs or something else that's easier to work with safely than these awkward little screw terminals.Either that or they could rotate them so that half of it goes in from the side, or move the two terminals farther apart, or... there are any number of approaches that would rectify the problem, but a half-millimeter-thick plastic separator just isn't nearly enough clearance in the real world.

I bought this for a wall-mounted Fire 7 setup to control my home automation. It's a little tricky to put together, because there are no instructions, but it took me a few minutes and two tries (I mounted the back panel wrong the first go around).I hooked it up to a 12V source, and since my Fire 7 needed 5V, I stepped the output down to 5V. On the other end I got a nice 24AWG right angle microUSB cable, cut off the USB A end, and crimped the ++ and -- together. After plugging my Fire 7 in, I noticed on the LCD readout that the amps out was only like .4, and the Fire 7 was having trouble charging. I looked at the power block that came with the Fire 7, saw it said the output was 5V 1.0A, so I upped the voltage out on the regulator a little bit. It's now putting out 5.7V and .95A, so it's enough to charge the Fire 7. I did go too high, trying to get the amps to 1.0A, but the Fire 7 didn't like that. However, it seems to have an internal stop and it immediately stopped charging, and after bumping the voltage back down, it started charging again.Also, I don't know if it's just specific to me, but my regulator has a high pitched squeal at anything below 5.6V output. Once above that, the squeal goes away.

It has absolutely no instructions the plastic pieces don't fit together I had to put it in a vice. I don't care if there is a PDF print out the sheet and stuff it in the bag 😒

I purchased this little DC-DC Voltage Converter for a project in which I am trying to restore some old LED TV Studio lights that had burnt out constant current drivers. I used this to prototype how much voltage and current the LEDs drew so that I can design a custom driver PCB to get them back in working order. It worked like a charm, and is a wonderful product!
