Korad U202 DC power supply - screw connectors
Details
The Korad U202 power supply is a compact power supply with 150 Watts of power and an excellent price/quality ratio. This power supply operates quietly, as its fan only activates when the output power exceeds 150 Watts. Moreover, the resolution of 10 mV and 1 mA is excellent for a budget-friendly power supply. Lastly, the U202 has two fast charging 24 W USB ports, output switch control, and over-current & over-temperature protection.
This version uses screw connectors for the output terminals. If safety terminals are preferred, please check out the Korad U202 with safety terminals instead.

I have loved this little power supply since it arrived. I only bought it because of the 2, fast charge USB ports on front for my tablet and phone. I figured I could fit it on the desk next to the big one, charge directly from it and have it handy if I needed a more power supply.
I was honestly surprised when it arrived because it is much better than I expected.
Very good building quality and accurate. And for the price, it's practically a gift. I highly recommend it. 5 stars in every way.
