DC Power Supply Variable 0-30V 0-10A, Adjustable Switching Regulated Bench Power Supplies with Encoder Corase & Fine Knob, 3.6A USB & Type-C Quick-Charge, Overcurrent Protection(OCP)

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.

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.

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

Product itself is solid. But it must be emitting a high frequency sound, the moment I turn on the power supply, my 2 year old Shetland sheepdog goes nuts. Barks, howls, whimpers... I just need to use this far away from fido. FYI, for Dog owners.... Never seen this type of reaction from our dog before, but even when the dog is out of line of sight and can't tell I turned on the supply, he goes off. Took off 1 star because of this issue.

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.

I did not push this very hard, but all the controls are easy to use and the display is bright and clear. It seems to be a solid product at the price point. One minor disappointment -- I was somewhat disappointed that the included clip cable had only lugs and not banana plugs.

I bough this power supply to test car parts and to use for my DIY projects. It also came with the aligator clips, so you can test things right away!

Total garbage, it wont work, and the picture in the product is a total scam, the power supply will not go over 25 volts, dont waste your money.
