Review: Finally, a solution for lost power adapters - All of the replacement power adapters I've purchased in the past have not had the ability to see exactly how much current they are putting out. With this one, you have a digital readout and a rheostat that allows you to fine tune the power output. Also comes with a very complete adapter set and a polarity reversal connector for the occasional input that is wired in a reverse configuration.
Review: Reliable Unit with Handy Connector Attachments - Bought this unit to power a water pump for a water feature. It works reliably and does a great job. The included connector attachments are very helpful, making setup straightforward and efficient.

## Questions & Answers

**Q: Is the voltage selector knob fitted with position detents? Can the selector knob get easily bumped to the wrong voltage?**
A: Dear customer,
The rotation control is not loose and will not switch to other voltage positions unless it is turned by an external force.

Have a good day!

**Q: What is the actual tested, rated voltage/current for the USB-C tip? Seems like it is a 5V tip.**
A: Dear customer,
The USB-C tip has no rated voltage/current, the output voltage and current mainly depends on your device.
Wish you have a good day,
Meiyue

**Q: Does the selection knob lock in to position? It seems like I could plug in a low V device, have a pet bump the knob, and fry the device being powered?**
A: It doesn't lock.

**Q: How can you determine the amps it is putting out?**
A: This supply is rated at 3 amps, the only way to know how much is putting out is to measure it with an ammeter and it depends on the load. If you are powering something that only requires 0.1 amp it will deliver only that. On the other hand if you try to power something that requires more than 3 amps (say a 24Volt 100 Watt light bulb which would require more than 4 amps)) it will current limit at 3 amps.

### ⭐⭐⭐⭐⭐ Reliable Unit with Handy Connector Attachments
*by T***G on November 26, 2025*

Bought this unit to power a water pump for a water feature. It works reliably and does a great job. The included connector attachments are very helpful, making setup straightforward and efficient.

### ⭐⭐⭐⭐ Works like a power supply.
*by M***T on February 13, 2025*

Good: - Fairly easy to use - Acceptable build quality - No abnormal heat or noise - Comes with adapters - Its adjustable Cons: - Not as reliable as non-adjustable power supplies - Voltage adjustment knob tends to move, maybe tape it down if need specific voltage consistently - Voltage display inaccurate, maybe have a multimeter on hand to verify Note: I’d say it’s alright for most people to use in place of a power supply if they lost theirs or just need a replacement. I suggest using a bit above the required voltage when using it as the voltage could fluctuate, though you could use more or less if you know what you’re doing.
