  • The perfect universal power supply!
Style: 3~24V3A 72W
I cant believe how handy this thing is. Works on everything. Perfect for trouble shooting or supplying non typical voltage to stuff.

  • Very good!

This power supply is amazing, I can charge almost everything at home now!!!

  • Seems generally fine for most applications.
Style: 3~36V4A 144W
I tested the voltage on a lab grade multimeter, both without load, and with a 4 ohm power resistor. The supply voltage to actual voltage was always within 5-6%, and it does drop under load. E.g. Under load it read 12.1, was delivering 11.6, with load removed it popped up to reading of 12.2 and actual of 12.17. While it'd be nice if it had both coarse and fine control knobs, the accuracy of the device doesn't really benefit from that level of precision. Noise on the oscilloscope seems similar to my low-end lab power supply. Seems generally ok. ... show more

  • Very handy to have! Voltage and Amperage seems accurate. I recommend it for the price.
Style: 3~24V3A 72W
I really like this handy power supply. Good variety of connectors, and the alligator clips are very nice to have. Very handy digital readout. I use this as a basic power supply when not at my bench, and for powering breadboard projects. Price is good, quality seems good also.

  • So wonderful to have!!
Style: 3~24V3A 72W
For the last 35 years I’ve been collecting and storing different voltage and amperage DC power supplies/inverters so that when one fails or I get a new device that needs one, I’m easily able to find what I need without having to buy one. I probably have two or three different boxes. Well, with this handy device power supply I can pretty much power anything I need due to it having variable current selection as well as nearly every tip/connection option I could ever imaging needing! I just used the first one I got to power anything slot car track I bought for my sons. And one of the best things about it (besides it costing half the price of the dedicated ones from the company) is that with the voltage being completely variable, I can adjust the speed of the track perfectly so that the cars aren’t flying off all the time! It’s great and I love the design that allows me to see the exact voltage it’s putting out. I also hooked it up to some LED string lights that we have and it’s nice that I can adjust the brightness of them as I thought the regular 12v power supply made them too bright for my liking. So I find these to be a great value for the money. I already have two and pretty soon I’ll be able to recycle some of the older power supplies I have laying around and just use these when the need arises. I wish that these had been available years ago as they make life so much easier. ... show more
