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

This NICE-POWER 30V 10A variable DC power supply is a great addition to a workbench. It’s easy to adjust, provides stable output, and works well for electronics testing, repairs, DIY projects, battery charging, and general lab use. The adjustable voltage and current controls make it very practical for a wide range of applications.The display is clear and easy to read, and the controls are straightforward, which makes setup simple even if you’re using it for different projects. I like that it offers both voltage and current adjustment, so you can dial in the settings you need with good precisio
Limited use so far, but am impressed with features and the coarse/fine knobs make it easy to set both voltage output and current. Appears to have good build quality. The price makes this a good value.
I’ve been using this power supply for a couple of weeks now pulling an average between 4 and 6 amps continuously.Voltage accuracy has been very good, no fluctuating of voltage very stable. When running long tests output remains consistent.NOTE: although the unit was an excellent choice and performed very well it did fail one week in after turning it on in the morning it started to fluctuate voltage and would cut off, when I turn it off and back on lights briefly comes on then shuts down. Although I need a second bench p/s I held off for now waiting on the dual p/s from nice-power hoping for a
This is an awesome bench power supply for a great price. You have coarse and fine control for both voltage and current output, plus power/on and current/on buttons for safety. You also have a 5 volt, 2 amp USB/A output option for providing stable power to prototype controllers like arduino or raspberry pi. I've used this bench power supply for a few projects, and it is a definite electronics tinkerer necessity. I've used it to test everything from GPUs to power tools, and it has been great. It was also great for cold-diagnosing problems with various electronics after a recent flood, to see if
It puts out what it says it does, shipped fast, lightweight, not noisy. Definitely recommend for the price.
Wish I got one of these sooner! I’m trying to repair a Power tool battery and this is such a handy tool. I can balance charge the pack without having to completely diss assemble. It took me a minute to get used to the adjustable part, the fine adjustment is limited so if you don’t start in a middle position you may run out of adjustment and will have to re do the other setting. It’s not a big deal, maybe it’s normal for this kind of tool. I’m not much of an electronics expert but I was able to use this and like it very much. It’s also one of those very versatile tools for tons of other uses. T
Amazing for the price, going to get another one real soon. I definitely recommend
