DC Power Supply Variable, Bench Power Supply with Encoder Adjustment Knob, Output Enable/Disable Button, Adjustable Power Supplies with USB Quick-Charge, Short Circuit Alam (30V 10A Black)

Very compact, easy to use.

User friendly and nice,very good product.

I bought this to power my silver cell. and it works perfect. a great feature that you really need for a silver cell. is it kicks off and alerts when the silver grows into the anode material. the accuracy readings are very close when you check against a multi meter. easy to connect. its compatible for any dc source. the adjustment can be fine tuned. it comes with cables and clips. its lightweight. and small enough to easily store. ive used it down to 1 volt and less than an amp. and used it to deplate silver plated items perfectly going up to 25 volts with no issue. the fan works great regulating its internal temp. i ran it 10 days straight in my silver cell. with no breaks. and it worked like a champ.,

It has been working great for me so far. Even the overcurrent protection is spot on. I use power supplies like these to test new battery-powered device prototypes to determine their operating voltage range and current limits, by artificially limiting voltage/current to realistic battery conditions and simulating power drain under load. This supply allows me to do all of that with ease and has proven very accurate. It's polling rate could be slightly faster, but I'm not gonna knock it at this price. It absolutely gets the job done for a hobbyist-friendly price.

The Encoder Knob Feels Much Better Than Buttons I didn’t think I’d care much about the adjustment style, but the encoder knob makes changing values fast and smooth. It feels way less annoying than repeatedly pressing tiny buttons to move voltage up and down. Output Enable Button Is More Useful Than I Expected This ended up becoming one of my favorite features. I can set voltage/current first, then enable output when I’m ready instead of connecting live power immediately. That feels a lot safer when working on unknown boards. USB Quick Charge Is Actually Handy I originally thought the USB ports were kind of a gimmick, but I’ve used them more than expected for: Phones USB-powered tools Small development boards Nice bonus without needing another charger on the bench. Feels More Powerful Than Most Beginner Supplies 10A gives enough headroom that I don’t constantly hit current limits during normal electronics work. It feels much more capable than the tiny beginner units I started with.djustment style, but the encoder knob makes changing values fast and smooth. It feels way less annoying than repeatedly pressing tiny buttons to move voltage up and down.

Love this DC Power Supply. It even remembers the last setting when turning it off and back on. That is very important when using the same voltage for most of my testing. It is so much better than using a car battery. I love the ability to control the amperage, so I don't have to use an inline fuse. It also shows how much wattage something is drawing, so you can tell if there is a problem with a device.

I've been using this power supply for a couple of years, and I'm always impressed by the ease of use of the controls. It is very easy to use, and I like the two stage process where you set up your voltage and amperage first, then push the output button. I also appreciate the color indicators that show when you have reached your target voltage, and I like to watch the progress of the charging process in real time. Good quality piece of kit for a reasonable price.
