Soon after arriving I noticed it's size and quality of build, and was very good for the price. Also my power supply was very well packaged. I have always played around with electronics and now I'm dabbling in ham radios so a power supply became necessary. I have used for many, many hours and can say it's a durable unit that performs well. Small in size, but has large digital screen that displays output voltage and amperage. Good appearance and easy to use. I wish it had a two separate power outputs, but I didn't want to spend extra money for a power supply with that option. (My choice) Bottom line is after hours of use I haven't experienced over heating, loss of applied power or any glitches. I would purchase again.

It supplies 30 volts DC at 5 Amps. It supplies 14.9 volts DC at 10 Amps. Thus, it is the power supply that puts out 14.9 V max at 5 amps max, and 30.0 volts at 5 amps max. You cannot get 30 volts at 10 amps! It is well built and it functions well. I like its small size, too.

Likes:Low cost, small footprint, nice displays, good looking, easy to set voltage and current settings (limits), well constructed inside. Load testing results show this power supply delivers as advertised. Limits at 150WattsVoltage setting: Push to select digit to be adjusted, then after ~3sec it goes from a voltage setting to a voltage measurement.Voltage setting: Push to select digit to be adjusted, then after ~3sec it goes from a current limit setting to a current measurement.Dislikes:EMI.Like most switching power supplies it comes with electronic noise (EMI), most of it under load.There is also a small amount of ripple at the output (~100mv) however I wouldn't say it is excessive (could be filtered out post power supply for light duty use)Great little power supply for battery charging and general purpose applications, however I would not use this for radio work.

Stable easy to use and controls are easy to understand.Worked great with my 12v QMX+ QRP Ham radio where initial startup suggestions tight limitation on current (during initial tests)

Besides being an excellent shop power supply, it also has a current regulating feature that’s great for powering current devices where the amount of current flowing through the load is more important than the voltage being applied.Set it for 30ma and set the voltage above the vf of a device like an LED and protect the LED from over current damage.Nice feature. Everything else works as expected.Nice PS.

Using it to power a Humminbird fishfinder indoors for training purposes. Works great set at 19 VDC.

Overall, gets the job done by allowing you to current limit and set voltage pretty precisely. One con with this device is the fan noise(on all the time), which isn't terribly loud when you just turn it on but gets obnoxious over and extended time. I simply disconnected the fan itself as I don't run it more that 30w at a time.

The accuracy of the displaced value of voltage and current is high and true to what you really get at the output terminals.

Feels plasticky and cheap but works fine.

I’m using this power supply for a electrolysis tankIt works very well for my application!

If you are using this for a set-and-forget applicaiton its great. Have used almost continuously for months with no issues.The problem with this unit is the interface to make adjustments. You have to press the knob to select which digit to modify then turn the knob. If you accidentally turn the knob while pushing it, you can destroy your circuit (example, if you want 3 volts but unit is flashing on the 10s unit, if you accidentally turn the knob a tiny bit while pushing it in, then it will jump to 13 volts, and you have to press button 3 more times to get back to the tens unit to drop the voltage down again). So using this for variable voltage or current, example while bringing up new circuitry, is not a good idea.
