Adjustable power supplies can be expensive, especially ones with extra features that you sometimes just don’t need. This power supply, available at Adafruit, is simple and affordable. It allows you to adjust the voltage range from 3 to 12 volts DC and 5 amps. It’s also very small, allowing you to take it with you as needed.
I can see a lot of very practical uses for this simple power supply, especially if you are working with LED strips.
They give it a 9 out of 10, saying it’s “Affordable for the power it can output.”
