Review: Great for Electroplating and power supply for my Silver Cell. - This puts the power where you need it, plus its light weight and compact. Started using it for electroplating but currently its growing crystals in my Silver Cell. Easy to adjust voltage and good quality for the price!
Review: Great for electro-etching - Works great. Used it for electro-etching aluminum and it maintained both 9 and 12 volts and limited amps according to what I set it to.

## Features

- Upgraded High-Precision Encoder Knob: Just "set" Voltage and Current instead of "adjust". You can press the Voltage and Current encoder knob to select the Digit you want to adjust, then rotate the knob to set the value from 0-9. Each Digit can be set easily by the accurate encoder knob. The encoder switch replaces the potentiometer switch, making your work easier, more accurate and efficient
- Precise 3-Digit LED Display: The NICE-POWER DC bench power supply has a resolution of 0.1V and 0.01A, and you can easily adjust it in the range of 0-30V and 0-5A. The 3-digit back-lit LED display provides more accurate and clearly visible readings for the voltage and current value, even in conditions of low voltage
- Small and Diverse Applications: Worried about the bulky power supply? This compact and sophisticated DC power supply weighs much less than a laptop at just 1.54 pounds, saving more space on your workbench. And you can use it in various scenarios such as laboratory, LED test, repair, electrolysis, burn-in test, electroplating, brush plating, electronic DIY, etc

## Questions & Answers

**Q: Does it have reverse-voltage protection?**
A: Yes the device does have a protection circuit inside. But in my use of the product it does not allow you to set a current limit. I brought 2 new devices and the current limiter just does not work on this product line.

**Q: Two questions: a. when I press power off, it stays on for about 2 to 3 seconds, why? b. How to limit 12v 1A output, current display is always 0**
A: It stays in power because of the capacitors so after you turned it off it will take time to empty the capacitors. 
If the current is 0 that means you do not have any load connected or it is so small. You cannot limit both voltage and current at the same time, you can use as Constant Voltage which will keep the output voltage at 12 V and the current will change according the load that you connect.

**Q: Does the come with a 110v power cord and the positive and negative output alligator cords?**
A: Yes, it comes with a 110v power cord and the positive and negative output alligator cords.

**Q: Does this unit do 220v?**
A: No. This power supply does not have an input voltage switch

### ⭐⭐⭐⭐⭐ Great for Electroplating and power supply for my Silver Cell.
*by N***F on January 23, 2026*

### ⭐⭐⭐⭐⭐ Great for electro-etching
*by A***. on January 13, 2026*

Works great. Used it for electro-etching aluminum and it maintained both 9 and 12 volts and limited amps according to what I set it to.

### ⭐⭐⭐⭐⭐ Works well, fairly accurate, be careful with the power inlet on the back
*by R***1 on January 23, 2025*

I needed a constant-current power supply for something I was working on, but wasn't sure how much use I would get out of one afterwards. Not wanting to spend a lot of money, I came across this supply that not only has the constant current capability I needed at the time but also a constant voltage function as well. This is the perfect size to sit with the rest of my bench equipment and looks right at home sitting on top of my bench DMMs. While the functionality of the unit is as advertised, I did have to knock off 1 star. That is for the standard IEC power inlet on the back. I at first thought I had a DOA supply but found that some IEC power cables are very loose in the socket on this supply, thus not making a good connection. I can work around it, so not a reason for me to return the supply.
