Customer reviews
Customer Reviews, including Product Star Ratings help customers to learn more about the product and decide whether it is the right product for them.
To calculate the overall star rating and percentage breakdown by star, we don’t use a simple average. Instead, our system considers things like how recent a review is and if the reviewer bought the item on Amazon. It also analyzed reviews to verify trustworthiness.
Learn more how customers reviews work on AmazonCustomers say
Customers have negative opinions about the voltage of the power supply. They mention that it displays an LUP error when the voltage drops slightly. Customers have different opinions on value, performance, and quality.
AI-generated from the text of customer reviews
Customers are mixed about the performance of the power supply. Some mention that it works pretty good, works great at low power levels, and is suitable for a solar powered station. However, others say that it didn't work or didn''t deliver power.
"...you check it with a multimeter and verify the actual reading, it works pretty good." Read more
"...But guess what? The replacement worked for a bit, and then it started smoking! Yeah, not exactly what you want from a voltage converter...." Read more
"...No issues working with the mag lock app or spliced in exit button. Couldn't be happier." Read more
"It just not what I need, it works well, I need more amps going through it, it just can't handle more than 4 amps" Read more
Customers have mixed opinions about the quality of the power supply. Some say it's very nice and well built, while others say it quickly self-destructed with defective components.
"...Modules are incredible well built circuits that allow your imagination to make complicated devices with ease...." Read more
"...Supposed to have current protection. But it fried itself on a simple LED light. So OPP isn't perfect." Read more
"...Don't get me wrong, these are VERY NICE units, well built and I would buy again for a project that was not requiring as much energy efficiency as..." Read more
"...a solar power controller, Battery Charging" and for the most part, it's perfect - easily settable max voltage and current, just what's needed for..." Read more
Customers have mixed opinions about the value of the power supply. Some say it's excellent value for the price, while others say it was a waste of their time and money. The UI is clunky, and the unit failed after 1 hour of operation.
"...The UI is pretty clunky, but that's to be expected in these kinds of cheap toys...." Read more
"Price is very reasonable. Operating instructions could be clearer as far as cycling through the different settings...." Read more
"...Input was 12v 3a and I was only converting to 19v 1a and it could not handle it at all...." Read more
"I really like this unit. It is also cheaper than if I built one myself...." Read more
Customers are dissatisfied with the voltage of the power supply. They mention that it displays an LUP error when the voltage drops slightly. Some customers also report that the unit is defective and dies when applying voltage input. They also say that the voltage reading is ever so slightly off.
"...has not decreased, I am going to say that the meter is not reading the amperage correctly as of today the meter is say .30 of a amp draw opposed to..." Read more
"...I believe this is a bug in the firmware, because if they wanted you to adjust every time, why would it save the voltage?..." Read more

Returned that one and got a replacement. The replacement works as advertised, the voltage reading is ever so slightly off. Even after re-calibration it’ll be around 0.2V off the actual reading. But as long as you check it with a multimeter and verify the actual reading, it works pretty good.

Other then this I like it. It took me a good 1/2 hour learning all the functions (some are totally useless to me) BUT/and but! U can't change from C° to F° ok thats another flaw. Wthell u have English on the Display, 50% of us use F°. Funny funny funny 😄

But gets the job done
I returned one of these because the ammeter display was grossly wrong (was 1.0A, but displayed 0.35A). The replacement does precisely the same. Calibrated it to read 1.0A, but it was still grossly wrong at other currents - it appears the unit was assembled with the wrong shunt resistor. Oh, well, I can work around it, but taking off two stars.
Minor Flaw #2:
Works great at low power levels, but could really use a fan at higher power levels. I only need this for lower power levels, so I'm OK. Adding provisions for a fan (i.e. mounting bosses) would make it easy to improve performance at no cost to the manufacturer. Take off half a star.
Positives:
Small, in 20 minutes of experimentation it seemed to work great. The UI is pretty clunky, but that's to be expected in these kinds of cheap toys. The display is sharp, bright, and large enough to be legible even to my old eyes. The nice thing about not having a fan is the absolute silence. I'd buy again, but I'll wait six months until this batch is used up and I can buy one from a new batch that hopefully has an accurate ammeter.

Es posible utilizar este equipo para suministrar mayor voltaje del que genera tu fuente de poder, siempre y cuando el amperaje de consumo sean menor al total generado por tu fuente de poder. Es decir, si necesitas 20Vdc a 1amp, y tu euipo genera 12Vdc a 4amp, entonces podras utilizarlo sin problema! Pero si tu equipo genera 12Vdc a 1amp, ni de chiste podras usarlo, ya que no hay suficiente para incrementar el voltaje.
El equipo tiene muchas otras funciones programables y es muy amigable. Si necesitas conocimientos de electronica y electricidad para usarlo, no es para principiantes.
