Review on 💡 Kungber DC Power Supply Variable: 30V 10A Adjustable Bench Linear Power with LED Display & USB Output, Coarse and Fine Adjustments by Jonathan Fernandez

I was looking for an inexpensive power supply to work with Raspberry Pi modules, Arduinos and related devices. The Kungber Variable 30V 5A DC power supply seemed like a good choice to me. I have a small workspace and the 3.4" x 6.1" PSU was a plus. The packaging was more than sufficient to ensure safe transport. In the box, the power supply was wrapped tightly in a plastic bag. The power supply came with an unconnected IEC power cord and a pair of patch cords with banana plugs on one end and alligator clips on the other. A small instruction manual is also included. The power supply makes a solid and well-made impression. The on/off switch is located on the back of the device above the power cord. It's a bit cumbersome, but not a big problem. LED indicators are clean and clear. I found the CC and CV controls to be very responsive. The USB Type-A port on the front is handy for charging your phone or powering most Arduino configurations. The mounting pins accept standard 4mm banana plugs and at least 16 gauge tinned wire. As with most power supplies, the center ground pin is grounded. The accuracy of the voltage and current display is within acceptable limits. With an output voltage of 5 volts, 625 milliamps, the noise was about 320 millivolts. As a power supply for experimenting with microcontrollers and similar devices, I think the Kungber Variable 30V 5A DC DC power supply is an excellent choice.
