3V - 24V 1.5A 36W Universal Adjustable DC Power Supply Kit AC Adapter Speed Control Volt Display ON Off Switch with Variable 8 Plugs

Everything about this experience was smooth. Ordering was easy, delivery was fast and greate customer service. The AlloverPower 3V - 24V 1.5A 36W Universal Adjustable DC Power Supply Kit AC Adapter Speed Control Volt Display ON Off Switch with Variable 8 Plugs itself is top-notch. Giving five stars because nothing went wrong and everything went right. Highly recommend!

I have an ultrasonic cleaner for cleaning vinyl records. It includes a little motor for spinning the records through the ultrasonic bath, but as designed, it's a bit fast. I used this to attenuate the amount of power it received so the motor would rotate more slowly. It worked perfectly.

Solid and accurate. I have this semi-perm bundled with a similar sized volt-ammeter to test LV LED (pkg to 5 or 12V), charging packaged "lost brick" items temporarily and other short-term supervised uses. Excellent value and much smaller and useful than a large ultra-regulated knob & button covered box that click-clacks & flashes. Wall (120V) cord a bit short & knob covers wide range so touchy, but not loose and amazingly unvariable voltage (based on external meter) Amps output dependant on draw from whatever it's connected to. Similar products offer less range and price equal or exceeding this AlloverPower unit, longevity unknown but has handled brief shorts and remote interrupt (OV shutoff) well. Plugs are good quality and very helpful. One of honest: Buy this now you need or will soon need project, handiman, hobby or 'where's that pwr brick' (wired to + center) must haves.

I bought this to hopefully use this multiple devices. One was a hand held CB and the other was a ccrain Hand Crank radio that has an internal battery you can charge. For the CB it worked great. The radio began smoking so I discontinued use. You can change the voltage, the issue could be that the listed voltage on the device you want to use might be inaccurate. So, I recommend paying attention while using this so that you do over heat up a resistor.

I wanted an adapter to control voltage on miniature incandescent bulbs on a model to a very precise voltage (22.5 V) and found this inexpensive power supply which turns out to be precisely controlled to 0.1 V and easy to install, use, and read. Users needing a specific voltage should note that the voltage changes under load (due to basic electronics) but the continuous adjustment makes it easy when the load is connected to slowly dial up to the desired voltage. Surprising bargain for such versatility.

I'm very happy with this power supply because it is adjustable and I can test it with any different products that I need to test or plug in and just dial in the right voltage it's really cool highly recommend this part

It’s simple: a 3-24dvc power source. Used it in a generator class for excitation voltage and to troubleshoot an AVR. Also used it in conjunction with dc plugs with pigtails, and the Milwaukee top-off to troubleshoot a large tonnage chiller’s PLC, and power supply board. It’s cheap enough not to get if you find yourself working with VDC control equipment and need to power something that was powered by something that went bad (as a VERY temporary fix to keep temps. in check while you make the more permanent temporary fix), or whatever else you need from 3-24dvc. Very handy to not have it. Solid buy.

Wanted this for a little project I'm working on just to have a quick and easy way to vary speed of a small DC motor... I didn't expect the world, just a crude dc source with a knob. Arrived in a clear plastic bag inside a bubble envelope... Wiring was disheveled as if it was a return unit. Plugged it in, clicked the knob, nothing. Hmmm. Maybe it's just the display that's broken? Checked with a voltmeter. Nope nothing. This vendor wins the prize. This is the first piece of electronics I've ever bought that was completely dead... If you're thinking of getting one, and wanna roll the dice, rest assured you won't get this one. It'll be in the trash a few seconds after I do a quick autopsy to see if the internal build/design is worth getting another from a different vendor.
