NICE-POWER DC Regulated Power Supplies (SPS-C Series)
4-Digit LED Display
The large and bright HD 4-digit LED display provides accurate voltage and current readings that are easy to view even in low-light conditions. Moreover, you can check the power output readings and working status of the adjustable DC power supply on the display.
High Precision Output
High-quality circuit board and premium components ensure stable and accurate output of DC regulated power supplies. The NICE-POWER variable power supply comes with a precise voltage resolution of 0.01V and a current resolution of 0.001A.
5V/2A USB Charging Port
The NICE-POWER adjustable switching regulated power supply is configured with a 5V/2A USB charging port, which allows you to charge your mobile phone, tablet or other devices anytime, anywhere. No more complaints about mobile phones or repaired devices not being charged in time.
Compact and Lightweight
The NICE-POWER bench power supply measured only 8.4(D)x3.3(W)x5.5(H)inches and weight of approx. 2.6lbs, which is a great space saver on your workbench. The lab power supply can be moved around without any frustration.

I bought this to help balance and charge my 2016 Prius C-type battery modules (not for the faint of heart-- make sure you do your homework before attempting this), and I have to say this power supply exceeded my expectations. It has a constant current mode and a constant voltage mode, but the interesting and convenient feature is that it switches automatically between these two modes according to the load you attach. If you set the max current to 2 amps, and the max voltage to 8.0 volts, it will deliver 2 amps while the battery voltage is at 7.7, 7.8, 7.9 and then when it reaches 8.0 volts it automatically switches to constant voltage mode and the current drops. It doesn't go to zero at first, because the battery was at 8.0v in part because of internal resistance, so the thing gently lowers the current and prevents the voltage from exceeding 8 volts. This was extremely convenient, as it allowed me to leave it unattended for periods of time without worry I would damage the modules by over charging. There are purpose-built battery chargers that will also do such things, with some added benefits of measuring the battery capacity in the process, but honestly I wasn't really interested in doing a deep exploration of every module, and I wanted to balance them all at once. Even quite expensive battery chargers can't produce the high current you need for large parallel banks of EV modules, so this ended up beating out the hobbyist battery charges so badly I returned those and I'm keeping this.The way I used it was to switch the whole battery from series to parallel by reversing the orientation of every other module (again-- you have to know what you are doing to try this, I have a degree in EE), and then I ran a 14 AWG wire connecting all the negatives together, and another connecting all the positives together. I just hooked up the power supply to the bank all at once. I set it to a max voltage of 8.0v and a max current of 4 amps (which divided by 20 battery modules is way below the 0.1C current standard), and then I could walk away and let the device do its thing. If you go to the trouble to check the output voltage delivered with the value that the unit displays on the screen, be sure to measure the voltage at the terminals-- as the voltage drop at 4A in the leads is significant. I found the readout to be decently accurate (though its only 2 decimal places past the decimal point, so not an ultra-high precision voltmeter by any means). I really like it. When its working hard, the fan turns on to prevent overheating, so it has a little personality to it to boot.It is a sign of the times that I was able to buy a $35 module, and a $30 power supply and then repair a hybrid battery that the repair shop wanted $3600 to fix. Today I have a perfectly working Prius C-type, a really sweet power supply, and $3535 dollars in my pocket. SMH.

Very nice power supply for the money. Accurate, versatile and nice quality. I needed another so I bought this model again. So nice, I bought it twice!

It works fine for what I need it for . I repair car stereos and is the perfect power supply for me.

Voltage and Current adjustment is very easy with coarse and fine adjustments. Screen is bright and easy to read. Serves the needed application at a very affordable price.

I use this for powering my telescope, computer, and camera equipment while observing. I would have preferred red displays - I took the unit apart to add red filters to the display and had a chance to inspect it. Solder joints are very clean and the whole thing is intelligently laid out. Construction is very solid. There is a 4-pin socket with the letters RX and TX marked - probably a interface for calibration.

This is a handy device for troubleshooting, and came at a very reasonable price.

I've never had one of these before, and the user manual wasn't a lot of help, but Youtube had several excellent videos. I'm using this in a project where I have a lot of LED's, and this lets me test circuits without over-driving them. I'm also using it to determine the correct voltage and current for no-name and salvaged led's. The leads are sturdy enough, and the connect posts handy screw-type. The panel display is large enough for my old eyes to read, and the nobs work smoothly adjusting voltage and current. One thing to watch out for - the nobs to NOT align with the display - so the the nob directly RIGHT of the current setting is actually the fine voltage control. It is NOT bad design, the positions are good for a compact unit. and once you have the muscle memory, its no problem. I have found it to be very stable and it matches my multi-meter readings, so I'm going to say its accurate. For the price it is AMAZING! I should have gotten one of these years ago...

It worked for about 2 days and then failed. it looks good but after a few days it simply did not work anymore. I was just looking for 5volts and then 12 volts to test a few very low power circuits, nothing challenging. I guess I'll disassemble it and attempt to troubleshoot it. 0 voltage output at this point. Bench power supplies should be reliable. this is not.
