Customers appreciate the value of the power converter. They say it works great for the money, is cheap, and is better than the switching voltage regulator component alone.

"...Value for the money? Absolutely worth every penny, so why did I give it 4 stars?..." Read more

"The price was right and these seem decently made. About half of them worked perfectly. With the others, I had trouble maintaining a stable current...." Read more

10 customers mention10 positive0 negative

Customers find the power converter straight forward to use. They say the POT has good range and is easy to set using a voltmeter. They also say the converters save time on boards troubleshooting and that the soldering on wires is a breeze. Customers also say they are good reliable step down converters.

"Installed three. Buck converters are the easiest, and I wonder how other companies charge so much. All three worked as needed, adjustment was great." Read more

56 customers mention37 positive19 negative

Customers are mixed about the performance of the power converter. Some mention that it works great, while others say that some did not function and some couldn't be adjusted. Some say that the boards were at least functional, and that they work well at converting solar power. However, some customers report issues with the boards not functioning and some boards that couldn' t be adjustable. Overall, the opinions are mixed and the product is a bit disappointing.

"...Testing on the bench, no-load showed this device was capable of performing as advertised...." Read more

"...I have opened and tested 4 of them and have seen no issues at all. They work as intended...." Read more

"...many turns to get down to 1.5 to 5 V. At low power these will run discontinuous and generate a noisy output that causes the reading on my Fluke DVM..." Read more

"...They seem to work well, although are a bit finicky to adjust...." Read more

16 customers mention7 positive9 negative

Customers are mixed about the output voltage of the power converter. Some mention that it puts out a good constant voltage, has a wide voltage range, and a useful power control feature. However, others say that it doesn't change and that the output is completely independent of input voltage.

"...These are not bidirectional; they will not boost voltage, only attenuate. Minimum differential is about minus 1.5volts between the input and outputs." Read more

"...The POT has good range and is easy to set using a voltmeter...." Read more

"...My expectations were not exceeded.Short version - input voltage was too high (totally my fault) and it failed...." Read more

"...Puts out a good constant voltage. They have gotten hot depending on the application, but never burned out...." Read more

15 customers mention10 positive5 negative

Customers are mixed about the quality of the power converter. Some mention that the build quality seems fine, it's super stable, and is a nice product for work. However, others say that it has extremely poor build quality, bad quality control, and shoddy soldering.

"...Definitely a plus for the electrical hobbyist." Read more

"...I tested all 10 and they work, build quality is really good...." Read more

"...this is my fault, this is also a safety issue because these pieces literally blow apart (the capacitor even leaves a smell behind) if they are wired..." Read more

"The price was right and these seem decently made. About half of them worked perfectly. With the others, I had trouble maintaining a stable current...." Read more

9 customers mention6 positive3 negative

Customers are mixed about the adjustability of the power converter. Some mention it's very sensitive and easy to adjust, with fine adjustments to dial in precise voltages. However, others say that some did not function and some couldn't be adjusted.

"...LM2496S - who knows, do we care? - Basic reference circuitry with an adjustable potentiometer - right for more, left for less. -- For..." Read more

"...They seem to work well, although are a bit finicky to adjust...." Read more

"...Very sensitive and easy to adjust...." Read more

"Easy to adjust in, wide voltage range, usable form factor. Noticeable whine after about 0.5A draw...." Read more

Buyer Beware
First thing first... This is absolutely my fault...While connecting this Buck Converter to a DC power jack I mistakenly wired the POS (+) and NEG (-) backwards and blew it up (see the picture). There is absolutely no reverse polarity protection for this Buck Converter.The first thing that went was the LM2596S IC voltage regulator, then the first capacitor, both blew in a spectacular manner shooting pieces all over my room (well, not ALL over, but pieces did fly, you understand).Value for the money? Absolutely worth every penny, so why did I give it 4 stars? For the simple fact that if you aren't paying attention when soldering it together you may end up with metal fragments in your eyes and everyone makes mistakes every now and then.While I understand this is my fault, this is also a safety issue because these pieces literally blow apart (the capacitor even leaves a smell behind) if they are wired incorrectly. Everyone makes mistakes, I don't think it would be that difficult to add a diode to limit the flow of current to one direction, then again, that's why I'm not making these and selling them.
