Good product. I have not had a chance to use it productively but testing shows good.

I got the DC power supply - FNIRSI® DPS-150 Programmable DC supply with the 100watt power USB-C.Unfortunately the power supply went out after a week and about a month later the unit itself shorted out at 14 volts at 2 amps with a Bench stable supply providing 20V of input to the device limited at 3.5 amps. Internal diode clamped because of an inductive spike testing an ECU on the bench. Also the power mosfets where the heatsink transfer material is places also shorted out near where the input voltage comes in. It may be repairable but you have to buy the replacement AP50P04DF PDFN-8L chip on AliExpress and the D7 diode I can't find a datasheet on it. I guess I blew about 90$ just testing this thing out. I do like the display and the control via USB using PC software and datalogging the power use but with the internal components failing to hold less than 5 amps controlling a ecu and inductive spike of a single injector testing a mosfet on the ECU, this DC supply failed. If its a stable current it will do fine but with a fast changing current, it doesn't perform well unfortunately. It definitely needs input and output protection for use because once it shorts, it will pull full current on your DC supply. Needs a thermal reset fuse or an in rush current limiter on the input and output. I love the products, just not confident in the DC supply DPS-150 now for critical testing of other components

I’ve been using the Fnirsi digital power supply for a month now, and it’s been excellent for my LED projects. Its compact design makes it perfect for working in tight spaces. With the AC to DC adapter, I’m getting a solid 20.0V input and 5A output through the USB-C port.The interface is user-friendly.It only takes about 5 minutes to get the hang of it. There’s a button on the side that activates the power output, and the indicator lights turn on when it’s running. I also love how portable it is! I can power it using a 50,000 mAh power bank through the 12V port, which makes it incredibly convenient for on-the-go use.The PC software is available for download. The installation process is a bit quirky, but once installed, it runs smoothly without any issues.Overall, this is a fantastic product. Five out of five stars from me! Highly recommended for anyone working on electronics projects.

Great product. First power supply, Took me a minute to figure it out but it’s super easy to use. Great value for the price.

Checked accuracy with Fluke 87 V true RMS multimeter and found it reasonable to 1mV. Banana plugs difficult to insert but will probably loosen up over time. Liked power supply with multiple USB connections. Measured output to a cell phone charge to be 5.2V. Starting and stopping a little clumsy with button on right side. Liked rotating screen position to allow for different uses. Although I know the screen size, would have preferred it to be at least 4" (similar to NanoVNA or TinySA). Time will tell if this unit performs as now.

For the 5 minutes I was able to use this, I didn't like it at all. Took FOREVER using the dial to adjust values. Super annoying. Then it died on me. Thank goodness for Amazon Prime!

The build quality of this DC power supply is top notch. It is compact and convenient to use. Good value for money.The output this power supply is limited by the input voltage (USB PD 20v or 28v).
