DC Power Supply Variable, 32V 10A Adjustable Switching Regulated DC Bench Power Supply with Intelligent Charging Mode, 18W USB Interface, Precision Encoder Knob

This power supply's accuracy on voltage is spot on, the current is with in spec, the controls are easy to use, and the body doesn't seem that cheap. The capacitors are Chengx. They aren't bad but they are pretty decent. The precision capacitors are precision caps. The pcb seems high quality. The LCD display is what you would expect. But over all I think this is a pretty decent power supply and will be good for beginners. The transformer inside its quite beefy for the rated output, so that's a plus. The internal out put cables are pretty thick, they should hold up to the full 30v 10a. I used th

I have an extensive off-grid home and I use the Kungber 30v/10a Variable DC Power Supply Variable to test items that I intend to add to the system. For me, testing an item often involves finely tuned DC input at *EXACTLY* 27.30v to match my Lithium Ion battery array made from upcycled Hybrid Car Batteries.The power supply arrived well packaged, with all needed leads, manual (actually readable, unlike many imported items), power cable and support information. I was genuinely shocked that it included a card promising a lifetime warranty, that fingers crossed, I'll never have to make use of.I set

They get a one-star dink for the first unit being defective (it was shorted internally and never got off Constant Current mode), but it was quickly and easily replaced (thanks Amazon Prime) and the new unit works great.The dials are a bit fiddly to get just exactly right, but it gets close enough and stays set very well. To save everyone time, here's the TLDR on how to set it up for use:1. Turn on, set what maximum voltage (Constant Voltage mode) you want the supply to provide using the "V" dials. Do not mess with the "A" dials.2. Once voltage is dialed in, clip the two leads to each other (mi

The device itself is beautiful and modern looking. My wife stopped and asked - what is that cute thing? It's small enough to fit on my hobby bench and really makes the space look bright and organized.I'm not an electrical engineer just a hobby tinkerer. The voltage output was off by less than 0.1 volts across the range vs the reading on my multimeter. I consider that good enough for my applications but if you are a professional electrical tech you might want to get a better unit.The two minor annoyances are that the power button is on the back and that there is a pretty big delay between turni

This charger has been running non-stop without any issues for over 4 days while I top balance my new LiFePO4 cells. This charger/power supply is a beast. It's only slightly warm and the fan hasn't even kicked on yet. Granted, I'm charging with low wattage, but I'm impressed by its ability to stay cool.There are two features that really swayed me to this particular power supply. The first is the coarse and fine adjustments. This feature seems to only be found on the pricier power supplies. The second feature I really liked was that it showed watts. While this isn't exactly critical to know, it'

22APR24 Update: I bought this "variable power supply" for charging my DIY LiFePO4 batteries at the recommendation of others that also DIY their own LiFePO4 batteries. After having used this variable power supply to charge...YES, CHARGE my 12 volt DIY batteries a number of times, I can honestly say that I am STILL VERY PLEASED with my purchase. I have used the Kungber to charge 2, 50 amp hour batteries and 1, 150 amp hour battery at least a few times each to bring them up to full capacity. I believe I also used it to charge the 280 amp hour battery that I also built. Needless to say it took a w

Excellent quality device for a very reasonable price. Large, easy to read LEDs, and the coarse/fine controls make it easy to set a precise voltage or current limit. I've been using a very old Lambda power supply that was huge, weighed a ton, and didn't have the voltage or current capacity of this one. In fact, I could put several of these into the same space as my previous supply.One thing to be aware of is that the constant current function is not instantaneous. For example, if you set the supply at 5 volts with a 20ma limit to power an LED directly, you'll likely blow out the LED. The curren

I’ve been using it almost daily for several weeks, and I have to say it’s quite good for the price. It’s a bit more accurate than my previous one, voltage stays pretty steady under load, and the 2Amp USB on the front is a nice bonus. From my limited experience (and without digging through the internals) it seems like a pretty standard power supply, but a well-engineered one. I even like that the off/on switch is on the back of the unit, because that makes it less likely that I’ll turn it on by accident.I really only have one notable gripe, but I do think it’s important to be aware of this befo
