Korad U202 DC power supply - screw connectors reviews

beliw 2.5 volts it is producing audible humming sound.
i hope it won't blow

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.
