Review: Great power supply for the money. - Great power supply. Weighs like it’s build good. So far it’s been working great no complaints. Seems to be accurate in the currents and pretty stable.
Review: This Power Supply does its job very well - 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.

## 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.
- Compact and Lightweight: The measures of the variable dc power supply is only 7.51 x 3.56 x 5.81 inch and the weight is only 2.47 pounds, which saves more space on your workbench and is convenient for you to carry when you need it.
- If your area uses 110V, flip the voltage switch on the back of the dc power supply to 115V (otherwise it may not reach the 30V output voltage).

### ⭐⭐⭐⭐⭐ It’s fantastic and handy to have
*by B***K on December 11, 2025*

I got this for a van build that I wanted to test out circuits and equipment for 12v and 24v before I have all the systems wired in. It works great for my dual voltage needs and I’m sure I’ll use it for other projects. It’s really small, lightweight and easy to use. FYI I couldn’t tell in the picture but it does come with a good set of test leads that have clips to attach to your equipment wires. No need to buy extra like I did.
