Review: Great little machine. - I bought this to power my silver cell. and it works perfect. a great feature that you really need for a silver cell. is it kicks off and alerts when the silver grows into the anode material. the accuracy readings are very close when you check against a multi meter. easy to connect. its compatible for any dc source. the adjustment can be fine tuned. it comes with cables and clips. its lightweight. and small enough to easily store. ive used it down to 1 volt and less than an amp. and used it to deplate silver plated items perfectly going up to 25 volts with no issue. the fan works great regulating its internal temp. i ran it 10 days straight in my silver cell. with no breaks. and it worked like a champ.,
Review: Fantastic little power supply! - It has been working great for me so far. Even the overcurrent protection is spot on. I use power supplies like these to test new battery-powered device prototypes to determine their operating voltage range and current limits, by artificially limiting voltage/current to realistic battery conditions and simulating power drain under load. This supply allows me to do all of that with ease and has proven very accurate. It's polling rate could be slightly faster, but I'm not gonna knock it at this price. It absolutely gets the job done for a hobbyist-friendly price.

## Features

- High-precision Encoder Knob: Different from general knobs, this DC power supply has a precise encoder knob. You can press the knob to switch each digit, and then turn the knob to customize each digit in the range of 0-9. Set the voltage or current you want more accurately.
- Output Enable/Disable Button: In the process of using the bench power supply, Output button can prevent us from forgetting to turn off the output and causing damage to the load. Just press this button to turn on or turn off the output of the power supply. This makes it more convenient for you to use the variable power supply.
- Overcurrent Protection: When the OCP function is turned on, if the load equipment is short-circuited during operation, the adjustable power supply will automatically stop output and send a buzzer to alert the user. Protect the adjustable power supply and load from damage.
- Precise 4-digit LED Display: The dc power supply is equipped with a high-definition 4-digit display with data accurate to 0.01 V and 0.001 A. It has constant voltage (C.V.) and constant current (C.C.) modes, which can be switched automatically. You can see the working status indicator on the display. Additionally, you can adjust the brightness of the screen according to your needs.
- USB Fast Charging Port: The variable power supply is configured with an 18W fast charging port. No more mplaining about mobile phones or repaired devices not being charged in time. The NANKADF dc power supply allows you to avoid this dilemma. It charges your devices quickly anytime, anywhere.

## Questions & Answers

**Q: Does using the usb port show how much current is drawn?  can this port's current be limited for testing?**
A: Current drawn on the built-in USB port is not indicated on the display.  The display shows only voltage and current associated with the main power outlets when output is enabled.  When output is not enabled, the display shows voltage and max current settings.  A USB connector could be connected to the main power output connectors and any voltage and current through that connector would be shown on the display.

**Q: is this machine good for gold and silver plating?**
A: I don't know what voltages are required for plating, but, it is a very good supply for the money.

**Q: Can this be used as a short circuit killer to repair phones and circuit boards?**
A: Yes, as long as it doesn’t exceed the max output rating 5A. It will go into protection mode beyond that point.  I use mine daily and for the money it is top notch.

**Q: Description says 100w, but at 10a x 30v, that should be 300w output. is the description wrong?**
A: It means you can get 10 Amp at 10v

### ⭐⭐⭐⭐⭐ This Power Supply does its job very well
*by W***N on February 12, 2026*

I've been using this power supply for a couple of years, and I'm always impressed by the ease of use of the controls. It is very easy to use, and I like the two stage process where you set up your voltage and amperage first, then push the output button. I also appreciate the color indicators that show when you have reached your target voltage, and I like to watch the progress of the charging process in real time. Good quality piece of kit for a reasonable price.
