Review: I just got this today, and so these are my initial impressions. The quality is decent. Judging by the relay sounds, it has four voltage ranges: 0 - 4.0, 3.5 - 9.3, 8.8 - 13.8, 13.2 - 18.4. The displays always show the output, so for example you can't see what current limit you are setting without a load attached. Being illuminated, they are easy to read. The knobs are both single-turn potentiometers, despite the manual stating that the voltage control knob is multi-turn. It is not difficult to select a voltage to 1/10V accuracy, which is all the display provides. You can select to 1/100V with a multimeter attached and a very steady hand, although it requires some back and forth to home in on the desired value. Two minor negatives: 1. My unit had something loose inside when I received it. I took the cover off to find out what. It turned out to be a small chunk of solder. 2. It smells bad, although that is fading and I do not expect it to be an ongoing issue. The unit operates as expected. It looks good. It's cool and quiet. I'm happy. Feel free to ask questions if you have any. UPDATE 3/8/2023: I've had it for almost nine years and it still works great.

## Questions & Answers

**Q: I just bought one and I can Adjust the Voltage but not the current, is there something I don't know?
Also lost my manual. Can't find a link. Thanks..**
A: I use mine for electroplating. When I hook it up, the amperage is adjustable and the voltage sets itself. I don't know why this is, but since I use milliamps and amps for plating, and I can adjust it, that is what I need. I suggest that you contact Tekpower customer service/technical department for further info.

**Q: Can this be used to power a car amplifier in home ?**
A: It depends on the amp draw of the amplifier.  This piece of equipment, though, is meant for temporary bench testing and not for a continuous power supply.  You would be better off looking for a power supply designed for continuous use.

**Q: How many watts is this?**
A: 18Vx3A = 54W

**Q: so what is the smallest mA this device can deliver?**
A: The lowest for me is 0.05 mA (50uA). For adjustments that depends a bit on the sensitivity of your finger. I needed to simulate a 4-20mA current sensor. I found that I could get better control by adjusting the voltage rather than the current. It was very easy to tune it in 0.2mA steps and I was kind of able to tune it in 0.01 mA steps but at this point it took me like 30 seconds to dial it and I was barely touching the nob.

As a lot of people said, it stopped working after 1 month. The voltage keeps dropping. It can only maintain 0.25a or so. So frustrating! 😞
