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)

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.

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.

This thing is major cool! Compact, lightweight, 10 amps of power, and precise voltage and amperage control. I also love the fact that the output is switched on and off without losing the display settings. Performs very well.

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.

For a professional workbench or homelab setup, the DC Power Supply Variable with Encoder Adjustment is a versatile and compact solution that offers a significant step up from basic analog-knob units. Its combination of digital precision and safety features makes it a reliable choice for everything from charging batteries to testing custom PCB projects.Precision Controls and ErgonomicsThe high-precision encoder knob is the standout feature of this station. Unlike traditional potentiometers that can be sensitive and hard to dial in, this encoder allows you to press the knob to select a specific digit and rotate it for fine-tuned adjustments. This ensures you can set your voltage and current with 0.01V and 0.001A accuracy, which is essential when working with sensitive microcontrollers or 3.3V logic. Workflow and Safety FeaturesOutput Enable/Disable Button: This is a major workflow improvement. It allows you to set your parameters and verify them on the display before actually sending power to your load, preventing accidental overvoltage damage to your components.Overcurrent Protection (OCP): The built-in alarm and automatic output shutoff provide a critical safety net when testing new circuits for shorts.USB Fast Charging: The inclusion of an 18W USB port is a convenient addition for keeping mobile devices or USB-powered peripherals charged without cluttering the bench with extra adapters.Compact Bench FootprintMeasuring approximately 7.5" x 3.5" x 5.8" and weighing under 2.5 pounds, this unit is remarkably portable. It saves valuable space in a crowded rack or electronics station, making it easy to integrate alongside an oscilloscope and soldering station.The "Leads" FactorWhile the performance and technical features are excellent for the price point, the physical design is strictly functional. The unit does not include built-in hangers or integrated storage for the test leads when they are not in use. While this can lead to some bench clutter, it is a common trade-off in budget-friendly "switching" power supplies. For a cleaner setup, many users find that adding a small magnetic hook or 3-D printed hanger to the side of their bench is an easy way to address this.Final VerdictIf you are looking for a high-precision, digital-entry power supply that prioritizes accuracy and safety over industrial "frills," this unit is an outstanding value. It delivers consistent, reliable power for a wide range of electronics applications, and its small form factor is perfect for any modern workstation. You truly get a lot of technical performance for what you pay for.

This variable dc power supply is easy to set up and go. It works flawlessly. The alligator clips are okay, but I suggest buying extras. They grip strongly, but bend easily at the pin. You’ll need them eventually anyway. It has a cooling fan built in and only runs when needed automatically. You can’t go wrong at this price. It has a built in fuse for any accidental overload. It looks very professional sitting on my bench.

Great power supply. Weighs like it’s build good. So far it’s been working great no complaints. Seems to be accurate in the currents and pretty stable.

Very compact, easy to use.

User friendly and nice,very good product.
