Works very well

I use on my USDR+ CN KO HAM radio. Solid, no interference and dial in exact voltage. Would buy again.

Enjoy the way you can adjust the volts.

That’s one sensitive control there!

Size: 3-24V 5AVerified Purchase

This works actually better than my expectations – but the problem I have with it is that the knob is just too darned sensitive. I got this to use as a 5v power supply, and it does a good job at that.

But you even brush against the voltage knob, and it’ll be at 4.5 to 5.6v with almost no movement. This needs to be as close to 5v as possible, so I adjusted it then sealed it with Marine GOOP sealant. That kept the knob from wandering – but I’m thinking I should have had to do that. A bit more resistance in the mechanism would have been nice!

Overall, like I said I’m very satisfied with it. The selection of tips fits virtually every electronic device out there (except some of the older USB connectors) so it’ll likely fit your use. And I hated taking a star off for something as minor as the knob, but that’s a significant drawback…

Would I buy one again? Yes – if I need a variable power supply again I would. Still have a lot of that GOOP left, after all… 😉

Bought to tesk Beelink GT-R 5 mini system issue

Reviewed in the United States on August 7, 2023

Size: 3-24V 3AVerified Purchase

Was having issues with a Beelink GT-R 5 micro computer shuttling on and off constantly. Tested the provided power supply and it would fluctuate from 16.9-19.1v. After setting this to 19v, plugging it into the system, there were no more issues. The only thing that I would mention is that the dial for the voltage is “very” sensitive. Make sure to put it some place that it will not be knocked over or bumped up against. After using to test, bought a power supply specifically for the system. Have used it on several other items and it works very well.

One size fits all

Size: 9-36V 3AVerified Purchase

Awesome product. Variable voltages makes it ideal for many uses as a charger or power supply. Lots of power for quick battery charging. Voltage does not vary under load conditions. Voltage setting accurate to within .2 volts. Highly recommended.

Solid and versatile

Vine Customer Review of Free Product( What’s this? )

This is a great little power supply, especially if you have lost an adapter or are testing to see if an adapter is not working. It is ideal for a hobbyist. It comes with 12 different barrel type tips for different sizes of connections. It goes from 3v to 12v, but the best part is that the voltage is infinitely variable. You don’t have to select 3, 5, 9 etc. You turn the knob through all voltages. So you can choose exactly what you need. It is solidly built and should last well.
If you need this, the price is ok. I ordered it more from a sense of nostalgia from the old experimenting days (when I had a couple like this). I likely won’t use it enough to justify the price, but then, I didn’t pay for it!! 🙂

Was able to find the right voltage and adapter part easily for a christmas lamp that I lost the dc connector for. Looks okay but I put tape over the lcd desplay so it’s not allways lit up.
