You can adjust the voltage by placing a multi-meter on the output, synchronously, using a screw driver to adjust a potentiometer. It can be minute adjustments to achieve a precise voltage.

Kindly reminder
These boards are adjustable current limiting, fixed 3A current limit.
Please make sure that this module within its working range before using.
Please don't output short circuit, otherwise the board would burn out.
When setting the parameter, please make sure output voltage is stable before using the module to avoid any possible damage.

Tips:
Please check if the product package is intact before opening.
Please check if the negative and positive terminals are accessed correctly before operating.
The input voltage should not be over 28 V to avoid damage.

Customers like the performance of the transformer. They say it works well, the potentiometer works well to dial the voltage output, and it's simple to use. Some say it'll work great for all sorts of electronic projects, and is reliable. Some mention that it'd be a dream in terms of form factor and performance.

Customers appreciate the value of the transformer. They say it's an excellent value for money, versatile, and great as a low-cost electronic firework. Customers also mention that the buck converters are incredibly cheap and excellent quality.

"...Love it overall, great package size, efficient and a wonderful value. Good to have in the bin for later projects." Read more

48 customers mention26 positive22 negative

Customers are mixed about the quality of the transformer. Some mention that the build quality is good, reliable, and stable. They say it has a nice stable output at 1/4 W load. However, others say that it's fragile, easy to break, and not stable at all.

"...They're extremely easy to use and the build quality is good too, aside from the functional but impossibly cheap set screw...." Read more

"...So it's too cheap to really be useful...." Read more

"...It has been stable and consistent for over a month now...." Read more

"The boards are very tiny, and easily damaged. I had a circuit that was working using them that stopped working and ruined a bunch of components...." Read more

45 customers mention20 positive25 negative

Customers are mixed about the output voltage of the transformer. Some mention that it manages the voltage on the capacitor very nicely, and can regulate power at 5V very well. However, others say that it changes the voltage to an extreme amount, and is difficult to control.

"...So I permanently glued it to my setup. And now the potentiometer is not changing the voltage on 3 of them...." Read more

"...This is a high efficiency buck converter, good for actually pretty decent loads, and you get 6 of them...." Read more

"...WORSE - the moment I put a load on the output, the voltage dropped a few decimal points. So I had to start all over again...." Read more

"...are incredibly cheap and excellent quality.. over preform and stay dang steady.. These are without a doubt the best cost to preformance ratio bucks..." Read more

37 customers mention24 positive13 negative

Customers are mixed about the size of the transformer. Some mention that it's very compact and can easily fit it into projects. However, others say that the boards are very tiny and easily damaged. The pot is small and the buck converters are smaller than picture suggests.

"The boards are very tiny, and easily damaged. I had a circuit that was working using them that stopped working and ruined a bunch of components...." Read more

"...This looked like a good option - small and "agile".As others have written - it's HARD to adjust...." Read more

"...These work perfectly.Pros:- Extremely small- 2 +/- output pads- No noise-..." Read more

34 customers mention21 positive13 negative

Customers are mixed about the ease of use of the transformer. Some mention it's easy to set up, and easy to solder wires to, while others say that the potentiometer is way too finicky and nearly impossible to set. They also say that it comes with no instructions or data sheet.

"...They're extremely easy to use and the build quality is good too, aside from the functional but impossibly cheap set screw...." Read more

"...Install is just a bit harder." Read more

"...Setting the voltage out put, is fairly simple. Worked, went from 20v to 12v no problem little fiddly but not to bad." Read more

"...Simple to use, gets the job done.No idea why Amazon wanted them rated for Warmth and Sheerness but tossed in 5 stars for those too...." Read more

11 customers mention4 positive7 negative

Customers are mixed about the noise of the transformer. Some mention that it has relatively low noise on the output, and is great for a silent mod. However, others say that the noise is high, annoying, and can be heard in an otherwise silent room. The voltage seems unstable, and the pitch changes randomly.

"...have mentioned: these are noisy (RF) devices, so particularly audio is subject to interference...." Read more

"...Pros:- Extremely small- 2 +/- output pads- No noise-..." Read more

"...and they were getting way too hot, and there was a ton of noise on the output line..." Read more

"...seem stable enough for micro controller. It does make a funny noise when under ANY load... I think I can deal with it" Read more

44 customers mention12 positive32 negative

Customers find the adjustability of the transformer to be difficult and fragile. They also say the adjustment knob is small and sensitive, making it difficult to adjust with accuracy. Customers also mention that the potentiometer is very small and difficult to use. Overall, customers are dissatisfied with the adjust ability of the product.

"...the only issue I had was adjusting the voltage output as the adjuster is so itty bitty...." Read more

"...As others have written - it's HARD to adjust...." Read more

"...on your application but I do like the idea of being able to fine tune the output...." Read more

"...As others have mentioned, adjusting voltage is a bit tedious and requires a small (tiny) screwdriver and it is somewhat hard to dial in, but it..." Read more

It worked great when I tested one of them. So I permanently glued it to my setup. And now the potentiometer is not changing the voltage on 3 of them. I am pretty sure I didn’t turn it too far but who knows maybe I applied too much force. So just be gentle I guess. Giving it 1 star because the product was great when it worked. But didn’t even last a few seconds of adjustments.EDIT: I changed my mind. They are working really good now. Yeah the potentiometer can be finicky but it works. By trial and error you can get the right voltage. Just be careful to go really slow and gentle while changing voltage. Don’t push down too hard and turn slowly.

5.0 out of 5 stars Very stable
Reviewed in the United States on July 28, 2023
I haven't tested much beyond setting the voltage and forgetting it. I used it to create in all-in-one module for adding bluetooth to an older car stereo and it also powers a wireless charger. It has been stable and consistent for over a month now.

I have read other reviews of input voltages exceeding the rating of the filter capacitor, so it's something to be wary of, but unfortunately there is no way to check the voltage rating of it so I cannot vouch for that.

Love it overall, great package size, efficient and a wonderful value. Good to have in the bin for later projects.
