  • Universal power supply review
Size: 60W Color: Black
This unversal power supply adapter works well and supplies the voltage expected. Like all these universal power supplys they have multiple connectors which are necessary but tend to be a bit short. Overall it works well.

  • Good if you understand what you are getting
Size: 60W Color: Black
The other reviews here are helpful. The voltage is not lab-equipment stable in that it does sag a bit with temperature. It’s also dirt cheap for a variable output power supply with a digital readout. Mine is driving 120mm fans in a small rack enclosure and the adjustability is great and it’s been in a hot environment for weeks chugging along. ... show more

  • Base size and fine tuned voltage adjustment - didn't work for me, but probably works for some
Size: 60W Color: Black
I had to return this mainly because the primary use I had for it was for a rechargeable razer. The problem is the base of the adapter for the size it uses, is too fat to fit into the razer. The base (the black part the adapter end protrudes from is 0.39" at the smallest and 0.46" when you get closer to the end that plugs into the adapter. I only take the time to explain this as it wasn't on my radar at all. All the round ones seem to have the same size base. I also was not a fan of how fiddly the voltage adjustment was. Dialing in a specific voltage isn't as easy as you'd think. The adjustment is by 100th of a volt. This seems like overkill. Notches (as another reviewer suggested) would be nice, but just making it so it would go up by a 10th of a volt, would probably be sufficient. ... show more

  • Great power supply

Infinitely adjustable, not just presets like some of the others. Easy to fine tune. Comes with many attachments too

  • Mostly works
Size: 60W Color: Black
I bought this power supply to test the electronic devices I build because of its reported power output and adjustability. So let's start with the positive. This power supply does, indeed, provide power. When tested with a reliable multimeter, the voltage displayed on the LED readout is what the multimeter reports. So that's a significant positive. Now, let's move onto the negative. The power seems flaky at best. I haven't taken the device apart yet, but judging by its weight, the power output is most likely PWM, and if the frequency is too slow, more sensitive devices will have a problem with it. A perfect example is found right here, in the advertising: the Raspberry Pi. After running into a number of small, inexplicable glitches in one of my projects, I placed it on hold and switched this power supply to my Raspberry Pi 3B+. That's when the kernel began complaining of low voltage. The LED read 5.1 or so volts and never dropped below it, so I increased the voltage to 5.4 volts. The kernel messages for low voltage went away, but would come back intermittently. So I bought a dedicated 5V, 3A power supply for the Pi and so far, no low voltage kernel messages. So that's a knock on it right there... Next, the dial to adjust the voltage is touchy. Very touchy. It's nearly impossible to get 5V; you'll usually end up with 4.87V or 5.22V or some other "close but not exact" values. Great for checking the voltage but bad if you want to find voltages that are too low for the device. Also bad for electronics where the dial gets bumped or nudged from 5V to 7V and the magic smoke gets released. Overall, it's a good design and will definitely worth for most devices. Just be aware that it may not work for you, if you need reliable power. ... show more

I just received my power supply and was surprised to find out it was used/a return. The box's seal was broken. A tip was already attached to the cord with was loose in the box. The power switch was already on. It appears to work, but there should be better quality control or a warning/ discount for seconds. Beware. ... show more
