Simple is efficient, efficient is productive
I'm no chemist.. i needed a Dc power supply for my electroplating & cleaningI didn't need 3 displays or bells n whistles.This was a Score.Not only is it exactly what I hoped. Constant, accurate adjustable DC current.It further came with at least a dozen different connectors & adapters.Meaning i can further charge my electric bikes, cordless tools, Bluetooth speakers, And everything else in my house that has a rechargeable battery.So essentially everything.All for one & One was only $18 bucks.Definitely recommend . .Definitely One of my top pics of the year to date.5⭐'z and up high.

It's electric!
Works as is should. Very handy!

Good for DIY and small projects, NOT permanent use.
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.

Works on telescope conversion. Very steady voltage
I'm an astronomer and I want to do some limited astrophotography by putting a camera on the back of a driven telescope. I bought an old Meade DS-2000 114m Newtonian, with an Autostar controller, strictly for this purpose. Back in the day, the DS-2000 was a really good telescope, with a reliable tracking system. The big problem is that it only took 8 AA batteries, with no option for ac, or even a 12v battery pack.I've been doing this for 30+ years now. I bought the telescope, which appeared to be in excellent shape, but untested, from shop Goodwill for $54 delivered. I wasn't disappointed. The scope looks almost unused. But I really don't want to run it using AAA batteries.I bought this Transformer because of the variety of connections, including the double snap fitting, like you'd use on a 9v battery. The battery holder in the telescope is connected by one of these connectors.After getting the Transformer set, I tested it by using the alligator clip connection. It ran the telescope perfectly. This telescope uses 12VDC so I set the Transformer to 12v. The power supply is very solid and steady through the Transformer, which I tested for 40 minutes.The idea of using the snap connection didn't stand the light of day; I realized I'd be running negative to positive, and vise versa, which obviously wouldn't work unless I switched some wiring around. So, I just sacrificed the alligator clips by cutting them off, and soldering them to the wires in the Meade. This left the barrel, which I easily connect to the Transformer wire barrel, to power the telescope.I ran the telescope for almost an hour, watching the voltage readout, and telescope tracking. The voltage remained rock steady and the telescope tracked perfectly for more than 30 minutes, before needing correction (excellent for this telescope).

works fine
second one I bought, good little low current power supply

Very first time turn on . No light nothing. No charge anything
Trust blinking voltage not stable. After 1 min stop working. Tried anything not led light again

Very imprecise
Ultimately mostly does what I needed it to, which was serve as a variable speed controller for computer fans in a DIY air purifier. The dial is SUPER sensitive, with no detents, markings, or any other way to get consistent, accurate voltages. It also changes voltage over time, I'm going to guess due to resistance variance from heating. Speaking of which, this gets WAY warmer than the basic 12v wall wart it replaced. I'm betting this thing is just a very simple 'dimmer switch' type design with a single variable resistor. I wonder if any power savings I get from running the fans slower is just being dumped here in heat instead.Part of the reason I bought this one specifically was the many included heads, including type-c. I was curious if I could crank this up to 20v with the type-c header and charge my laptop with it. The answer to that was "no." I don't know if that's a problem with this though, I don't know exactly what is required to charge via type-c on my laptop.If you need to set a very specific voltage, or even just have it stay constant if not at an exact value, look elsewhere.

If you know what you're doing this is awesome!
For the price and what comes with it this is the best little multi use power supply in a tiny form factor! It works exactly how I need it to and the included stuff is such a bonus in helping me fix some of my stuff I just made new plugs for it!It also doubles as a battery voltage meter if you unplug it with the knob still on lol I unhooked it the other day and saw it was reading 4.1 volts off the battery I was charging before I unplugged it from the wall! Definitely a cool feature not sure if it's supposed to do that but it's cool that it does! HahaCharges pretty quickly too anything I've used it for has charged way faster then included cables when you charge batteries directly and safely at a much better amperage then the cheapo USB cords with barely half an amp compared to this thing pushing 2-3 amps for things that can take it
