Product was as described. The board is very well marked and the assembly instructions are very good. Operation is fine. Very smooth output.

Performs well. Took time to assemble with clear instructions. Output 1.2v to 15volts not only 12v. Love the clear enclosure. Mine is 110v.

I just finished it last night and now i have a nice adjustable desktop power supply. Thanks from the united states! !

everything is ok, I still have to solder it, but it’s the second one I’ve bought. the other one works well, just don’t exceed the current (a few hundred amps).

What a beautiful little project. Took about 2-3 hours with my very novice soldering skills. Instructions were very clear. And there’s even a great video to follow along — even without understanding what’s being spoken in the video, it is very clear. Thanks for a great little kit! !

Everything fine, excellent seller.

Excellent little power supply with a very good quality/price ratio, and quite pretty by the way.
Very practical for testing components and small assemblies before final integration.
The circuit is absolutely not compact, the components breathe and cool, the layout is explicit so it’s quite educational to understand how a power supply with decoupling works.

Ive had issues with getting items through the speedx delivery service in east us, but this one made it after i made an arbitrary update to my delivery instructions on their platform.
The only complaints i have about the item really come down to the case. One of the acrylic panels was broken and i needed to hot glue it back together. Another panel had holes that didnt properly line up with the output screw terminals, which means i need to remove that panel anytime i want to install different output wires.
The circuit works nicely and has current limiting built-in. If you short the probes, thats maximum current which could possibly damage the circuit if it were not for the current limiting. Because of the current limiting, voltage drops immediately down to ~0.02v.
You can set the output anywhere from 1.5v to 17.7v, so it’ll work well for low voltage projects.

A fun little cheap project to learn about pcb’s. The directions could be a little better and easier to understand.

Excellent kit with clear building instructions in chinese and english. Works very well once assembled. I have just added a power switch on the 12v circuit and longer wires for the output.

Easy assembly. Works nicely
