Voltage sag during a wind storm fried the power supply to my aquarium light. Bought this to replace it. The end it came setup with plugged right in, I just dialed it to 20v and the lights are on! Read more

Truly Useful

Charles Sewell—December 22, 2025✓ Verified purchase

Eliminate batteries on so many electronic devices. A little hard to adjust to a certain voltage but I still prefer the adjustment knob over switches. Read more

★★★★☆

Good for DIY and small projects, NOT permanent use.

T.R. Welter—April 25, 2025✓ Verified purchase

The media could not be loaded. Supplies the right voltage, slightly higher than on the. but it's kind of unsteady at certain points. I could only upload one video but around 9 volts. It's all over the place. 12 volts. It's a little unsteady, but in the lower end around 3v or the up around 24 it's fine. Came with a decent number of accessories and the alligator clips make it super useful for what I'm using it for with small electronics projects. Knob the control knob is a little loose. You have to be very gentle to get to a precise voltage and it maxes out at about 75% and has a dead band all the way to fully turning the knob. Just a small quality control thing. But I noticed it.
