Works well at a great price
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.

Easy to use.
Nice and compact. Easy to use. I was able to bring 2 40v kobalt batteries back to life. The batteries are at least 100 each. This unit was 65 so itâs a great value.

Exactly what I was looking for
I was looking for something just like this. The price is great. It came very quickly. It has about 3 foot leads, which are great with the alligator clips on the end. Works like a champ.

Good inexpensive power supply
I put this power supply through it’s paces today. “Short circuit protection” was a blown fuse on the unit. Came right back to life after replacing.The measurements were checked against a calibrated and certified fluke meter and was 2 to 3 percent off. Not bad, and I have not opened the unit up to see if it can be calibrated.The coarse adjustment knob is really sensitive. Expect to spend some time dialing in the spot on voltage.My unit is staying in constant voltage no matter what I do. If you experiment with constant current such as diode laders or LED’s, I am not sure how well this unit will work for you.Overall, you can’t beat this for the price.

Great hobbiest tool
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…

Great Bench Power Supply
I found this bench power supply to be exceptionally easy to use, very accurate, and very stable. I use it to test electronic circuits in design. The unit is small sized and doesn’t take up much room on my bench. The LED displays are bright and easy to read from a distance. This is now my main bench power supply.
how do I rate it? –
Works good
This comes with alligator clip leads. No need to order more if you don’t need them.

Good for general purpose
Like the digital meters, voltmeter is fairly accurate to about .1V. Ripple is low but increases as current draw does. One big negative is that it is really RF noisy being a switching supply. Not good for running transceivers or receivers. Was specially noisy on the HF bands around 14Mhz, no offset control to “tune” out the noise. Will be fine for general purpose use such as motor control and some prototyping. The price was right for a cheap general purpose supply that is compact on the bench. Can’t speak to reliability yet, will update in 6 months.Nov. 2024 update. Fan is noisy and turns on often even when the supply is not being used but turned on and just setting on the bench. Works ok for quick testing of devices, then I turn it off because of the fan noise. Will keep it since the price was very affordable.
