Great power supply for any electronic projects
Got this for my teenage son for Christmas as he has begun to show interest in electronic projects. This has been s reliable and affordable option for powering various electronic projects. It offers stable voltage and adjustable current, making it versatile for different needs. The design is compact, and the display is clear, showing both voltage and current readings. It's easy to use and works well for hobbyists or professionals needing a consistent power source. Overall, it delivers good performance at a reasonable price, making it a solid choice for those in need of a DC power supply.

WORKS GREAT! (Once you set the input voltage switch properly!)
I purchased this power supply to test some antique tube-based geiger counters that originally ran on obsolete high-voltage batteries connected in series. Since modern replacements for these 45V or 67.5V batteries can be quite expensive, I wanted a reliable and adjustable power source to confirm the functionality of my equipment before making a larger investment. This power supply turned out to be a perfect solution.Right out of the box, I was impressed by its compact size—it was smaller than I expected, making it easy to fit on my workbench without taking up too much space. The setup was straightforward, and adjusting the voltage was simple and precise. I tested it on multiple pieces of vintage electronics, and it performed flawlessly in every case. The voltage output was stable, and I encountered no issues with noise or fluctuation, which is crucial when dealing with sensitive tube-based circuits.If you're working with old tube electronics or any other equipment that requires adjustable high-voltage DC power, this unit is an excellent choice. It's cost-effective, reliable, and easy to use. I would highly recommend it to anyone needing a flexible power solution for vintage or specialized electronic projects.

Works well for the price
Works well enough. It's exactly what you would expect from a basic power supply at this price. Relatively accurate current and voltage setting and I appreciate that it shows you watts instead of having to calculate yourself. I ran the 30V 10A unit overnight at the full 10A output and it did it with no problems.Minor Complaints:The beep sound is a bit loud, but I think it's a piezo buzzer and you can probably just open up the unit and put something over the hole on the buzzer to lower the volume. Also there isn't an enable/disable output button and instead you have to turn the whole unit on and off which involves it booting up (takes about 3 seconds) and making a loud beep sound. Many load conditions will cause the switch mode supply inside to create audible noise.Overall I'm pretty happy with the product since it powers circuits perfectly fine with no issues and that was all I really needed.

Nice compact and inexpensive power supply.
Had a problem with one of these power supplies and the company took care of it. Excellent customer service. This is a Switching type of power supply so there will be some noise on the output but can be filtered a number of different ways. The Display is bright, large and very easy to read and moderately accurate. Would be nice if calibration information were provided in the owners manual. Also wish it had an output on/standby switch so I could turn connected systems on/off without turning the power supply actually on/off. All the linear power supplies that I have designed and built have that feature and very handy at times.Overall a nice compact and useful power supply but not sure I would use it with

Works great, but clips could be better.
So far, my experience with this has been good; it's easy to use and feels solid. The unit was lighter than I was expecting and fits well on my workbench. Nice addition to my setup. My only complaint is that the alligator clips are cheap and hard to open with the rubber sleeve on. The sleeve makes it nearly impossible to get the friction you need to open the clips, and once you do, it's too easy for a finger to twist and bend the clip (like my negative clip did on its first use) Do your self a favor and buy some better test leads for this and you'll be happy! Additionally, the USB is separate from the output voltage and is not controlled by voltage or amp adjustments. Also, the USB-C is PD QC, so if you are trying to use the USB-C on a device that does not support it, you get nothing.

VERY impressed with this totally adjustable PSU - Great Value!
A switching PSU, but lighter than I was expecting. It works GREAT! It is a fully adjustable PSU. Pretty amazing technology for the very low cost. Works fantastic for my application (high current sub-woofer amp). I would highly recommend this for "bench" use, or otherwise (CB Radio, HAM)...or just for a test repair PSU. Fantastic!

Great Power Supply for the money
It's a great little desktop variable power supply. I purchased this mostly for balancing the cells on my LifePo4 batteries. It has worked flawlessly. Both course and fine adjustments work smoothly and one increment at a time. To balance my battery cells, I pull the battery down to about 80% and then connect the power supply. I then adjust the supply to apply roughly .250 amps and leave it there until the BMS shuts off the charge. A useful added feature is the USB ports, which work well. I have cranked it up to 10 amps to speed the process by bringing the battery voltage to about 13.2 volts and then turning it back down. In doing so, the fan automatically comes on and runs for 30 seconds or so, then shuts off. Some reviewers mention that the fan is loud; it is. However, I do not find it to be excessively loud, and in my mind, I want it moving some air so I expect it to be audible. The more it blows, the better it is. It moves a lot of air, it does not have to run long. I have no problem recommending this power supply.
