Review: In-depth and unbiased review - I was just like you, the person who is reading this right now, on the fence and looking for a more guided review, well here's my take on it. Short story, I was looking for some buck converters, something cheap and quick to arrive and works as expected. After testing all five of these today, I can say that this item does all three, but how did I come to that conclusion. Other reviews have mentioned that you'll need to swing the potentiometer a lot, and testing all 5 confirmed this to be accurate, now in my testing, I set up a bench top power supply, set it to 14.4v DC and each one needed on average needed 6.5 turns counter-clockwise to even register a 0.2v decrease, I've shared a full table of how many turns you need to affect a change, for me I want to use these in an automotive case and stepping down to 5v DC, this needed an incredible 11.5 turns counter-clockwise. Ok, so in a 30 minute test, I ran an incandescent car lamp just to see how stable it is and also how much heat it generated; unloaded it was set to 7.5vDC, with the lamp connected the load pulled the 7.5vDC down to 7.42vDC which impressively is only a 1% drop! After 12 minutes the board got upto 41.5°c and I tested it on a very warm day with an ambient temperature of 28.9°c, so an increase of 12.6°c which isn't too shabby either. I could ramble on about the other 4 units, but they all behaved exactly the same! Once you understand their behaviour these are a robust little unit. I've left on on test with 28vDC input and 7vDC output drawing 10w of power and will update in a week's time to see if they will pass an endurance test also. The only very small issue I can see is the output capacitor (220uf 35v VT) could be a little bigger, but I don't mind adding my own 470uf. Overall, I'm more than pleased with this purchase and if the test passes, I'll update this review and order some more
Review: Pretty good overall. - These little gems are brilliant. Granted, there's no way they will power your house, but then, that's not what these are about. When you need to derive a lower voltage power supply from a higher one, these are the puppies to go for. They are adjustable from (In my testing) 1.3V up to around 34-36V DC The instructions suggest making sure the input exceeds the output by a minimum of 1.5V I would further add that if you only want (For example) a 5V output, try to keep the input as close as you can, this minimises the power and so, heat, the unit has to dissipate.

## Features

- Input Voltage range: The Input voltage range is DC 3 V to 40 V. Note: Input voltage must be 1.5 V higher than output voltage, no boost.
- Output Voltage range: The output voltage range is DC 1.5 V to 35 V and is continuously adjustable, with a maximum output current of 3A.
- Easy to DIY Manually: Connect the power supply, monitor the voltage with a multimeter, adjust the swirl button on the blue potentiometer to obtain the required voltage, boost clockwise and boost counterclockwise. Note: The factory default setting is 18V. Before the voltage starts to drop, you need to rotate in the reverse direction for about 7-8 revolutions, 1 revolution means +/- 1V
- High Precision and Quality: The buck converter consists of a 36u thick circuit board with high Q inductors with high power output LED indicators, suitable for various electronic projects.
- Quantity: 5 piecess; Size: 43 * 21 * 14 mm (with potentiometer).Hurry up to add a shopping cart and click to buy!

### ⭐⭐⭐⭐ Surprisingly ok
*by M***. on 14 July 2024*

Initially thought these were faulty because the output voltage wasn’t changing with the screw adjustment. Turns out that you have to screw the adjuster in a lot before the voltage starts to drop. Once the voltage starts changing the adjustment is ok.
