Universal 3V - 24V 1.5A 36W Adjustable DC Power Supply Adapter Speed Control Volt Display with Variable 8 Plugs and 1 Polarity Reverse Cable Cord

Works exactly as needed, on an ultrasonic record cleaner to slow down motor rotation.

I bought this power supply to run 40 turnouts on N scale my model railroad. I have a lab power supply, but it has fan noise. I will be buying another to run my led lighting. I like the selection of adapters. One reason I bought this is the screw in two wire DC connector.

Comes with many adapters and is very handy for easy electronic testing. Accuracy is close with +- 0.2v underload Drawbacks: 1.5amps is not a great for long term use. Good for testing but not for permanent power Brick gets fairly warm during use above 9v

I bought a couple of these for my LED systems that y use when I'm doing my videography stuffs. They where for my LED lights for livestreams. You can't always change battery between a live event. But I have to say it's multi purpose adapter. Because I can also power my camera if I need too. I can power up switches for networking during livestreaming. So they are super handy to have. The only thing I could wish for, is that the dial has steps. Right now sometimes you have to be soft to find the right amount of Volt. And it did not happened yet, but people could accidently step on the dial and change the value

I like the precision and ability of being able to dial in the exact voltage I need for a specific application and the LED display of that voltage. The addition of the polarity reversing patch cable is paramount in this case. I needed a charger that would be capable of charging a specific device in the opposite polarity of what most items are. This made it a very universal charger in my opinion. It works on a standard that allows me to purchase any additional charging tips that I may require for a given device. It came with several popular tips. I have only used it a couple of times and don't know the longevity yet but I am hoping it lasts for a good long time.

We got this power supply as a replacement for a pretty high end Korg piano. The previous owner had hacked some sort of pc power supply that finally quit. The options, various voltages, and multiple plugs, including a reverse polarity adapter made this the perfect choice. We’re back playing music and it works really well so far! Dialed it up to 21 volts, and bam! Music!

I bought this because I needed a 3vDC power supply and the future flexibility of an adjustable supply with so many connectors and an LED display was very attractive. I unfortunately discovered that the power supply cannot be adjusted below 3.59vDC. The adjustment knob is a little too easy to turn as well. The voltage can be changed considerably by bumping the transformer. I’d probably get one of the power supplies with an embedded switch that you have to put a flat blade screwdriver in to adjust if I had known these things up front.

Excelente
