Review: Works perfect and came with MANY adapters. - Works exactly as needed, on an ultrasonic record cleaner to slow down motor rotation.
Review: Nice one. - 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.

## Questions & Answers

**Q: it is a linear adjustable output....   or does it have specific switcj steps/adjustment points for output voltage....**
A: On mine, there are no specific steps. There is a knob to turn to achieve whatever voltage you need down to 1/10 volt

**Q: Can this be used to charge a Bluetooth speaker?**
A: That's one of the things that I do with mine, Jack. I use it to charge smaller electronics including a Fugoo XL Bluetooth speaker.

**Q: can you split the DC side to two wires, one positive and one negative?**
A: Hmmm... I'm not sure I understand the question. The output is a 5.5mm x 2.1mm barrel connector with the center terminal positive and the outer sleeve negative. I don't know how how you'd have DC or AC current without two wires from the source.

**Q: will this power a Jackery 1000W at 30V - is there a compatible connector?**
A: Absolutely not. The maximum voltage output is 24v, maximum current is 36w.

### ⭐⭐⭐⭐ Great product with limitations
*by A***R on September 9, 2022*

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
