  Time will tell, but seems like a great purchase.

  Just got it, so take that into consideration when reading this review. However, after opening, powering it on, and spending an hour putting it through some initial testing I am VERY happy with this purchase with the exception of one itty-bitty issue (see last paragraph).Obviously time will tell, but it looks and feels like a quality unit. I purchased the 30v-10a unit and after measuring with a good multimeter, the NANKADF accuracy is dead-on below 15 volts and within .005 volts at higher voltages. That's more accurate output than a wall-wart and most PCB power supplies (7805, etc). The encoder knobs are wonderful and let you dial in the voltage/current level you desire easily and error free.I did not find the audible "beep" when turning/pressing knobs to be either loud or annoying as others have suggested in their reviews, however you can disable this although I found the included instructions a bit confusing.1) Press the output button continually until the unit goes into setting mode.2) Press the VOLTAGE button until the AMP number shows "4".3) Turn the VOLTAGE button until the WATT number shows "0".4) Press the VOLTAGE button until the AMP number shows "6".5) Press the VOLTAGE button once more to save the settings and return to operational mode.My only complaint is that after selecting and setting the 4th digit for both the Voltage and Amp displays, the unit automatically defaults to the 3rd digit for subsequent adjustments when it should remain selected on the 4th digit. For example, if I want 25.64 volt output, I select and set the first digit to "2", select and set the second digit to "5", select and set the third digit to "6", select and set the fourth digit to "4". My next turn of the Voltage knob should either increase or decrease the "4" in the fourth digit because that was the last digit I selected. However after a 5 second delay, turning the knob changes the value of the "6" in the third digit and so I have to press the knob moving through the display to get back to the fourth digit to adjust it again. While I don't anticipate spending a lot of time adjusting tens of mV, it is nonetheless a little aggravating.Ver másVer menos

  Great affordable test bench power supply

  This item works really well. It is a great affordable work bench power supply. It's incredibly straightforward to use, and is easy to connect to. The power provided has been stable in the times that I've used it, so I like this device.

  Great little machine.

  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.,Ver másVer menos

  Fantastic little power supply!

  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.Ver másVer menos

  High-Precision Bench Power at a Budget Price

  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.

  Nice supply!

  I like the fact that you need to enable the supply. This is a feature that might help to prevent your project to go up into flames, hi, hi. The display will show the selected voltage before you apply it to your device.
