Review: Works well at a great price - 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 automatically switches to constant voltage mode and the current drops. It doesn't go to zero at first, because the battery was at 8.0v in part because of internal resistance, so the thing gently lowers the current and prevents the voltage from exceeding 8 volts. This was extremely convenient, as it allowed me to leave it unattended for periods of time without worry I would damage the modules by over charging. There are purpose-built battery chargers that will also do such things, with some added benefits of measuring the battery capacity in the process, but honestly I wasn't really interested in doing a deep exploration of every module, and I wanted to balance them all at once. Even quite expensive battery chargers can't produce the high current you need for large parallel banks of EV modules, so this ended up beating out the hobbyist battery charges so badly I returned those and I'm keeping this. The way I used it was to switch the whole battery from series to parallel by reversing the orientation of every other module (again-- you have to know what you are doing to try this, I have a degree in EE), and then I ran a 14 AWG wire connecting all the negatives together, and another connecting all the positives together. I just hooked up the power supply to the bank all at once. I set it to a max voltage of 8.0v and a max current of 4 amps (which divided by 20 battery modules is way below the 0.1C current standard), and then I could walk away and let the device do its thing. If you go to the trouble to check the output voltage delivered with the value that the unit displays on the screen, be sure to measure the voltage at the terminals-- as the voltage drop at 4A in the leads is significant. I found the readout to be decently accurate (though its only 2 decimal places past the decimal point, so not an ultra-high precision voltmeter by any means). I really like it. When its working hard, the fan turns on to prevent overheating, so it has a little personality to it to boot. It is a sign of the times that I was able to buy a $35 module, and a $30 power supply and then repair a hybrid battery that the repair shop wanted $3600 to fix. Today I have a perfectly working Prius C-type, a really sweet power supply, and $3535 dollars in my pocket. SMH.
Review: Great Value for your dollar!!! - This 15v 10a variable desktop power supply is an extreme bargain for what you pay. It's simple and basic, but it works fairly accurately, and it is cheap, cheap, cheap. Maybe I should say inexpensive, as cheap has negative connotations:) More usb ports and a couple of usbc ports that are metered would be awesome, but that might drive up the price, and I was looking for a very inexpensive desktop variable supply. It's only been a few days and a handful of hours of use, but I am very happy with it so far.

## Features

- Precise 4-digit LED Display, Auto Power Calculation: The NICE-POWER DC power supply variable is a professional switching power supply regulation device with a high resolution of 0.01V and 0.001A. The variable power supply features a big bright 4-digit LED display that shows the adjustable power supply output values of Voltage (V) / Current (A) / Power (W) in real-time. The high-definition backlit 4-digit LED display provides an accurate and clear readout for the voltage, current and power values even if you are in low-light condition
- OUTPUT Switch Control: Sometimes we need to switch between different voltage or current outputs in experiments or work, but we often forget to turn off the output and causing damage to the load. The adjustable DC power supply OUTPUT key is designed to solve this problem, just with a single press of the added OUTPUT key, you can easily turn the output on or off. The required voltage and current can be adjusted without actual output power, which makes this benchtop DC power supply more secure and more energy saving. Also, you don't need to remove the load or turn off the power each time, making the variable DC power supply more convenient and efficient to use
- Reliability and Safety: Safety is our priority, all lab power supplies are certified. The adjustable switching regulated power supply is built with premium electronic components and reliable circuit designs that include multiple protection functions, such as leakage, grounding terminal, over-voltage, over-current, over-power, over-load, over-temperature, short-circuit protection to ensure stable working performance and prolong the life of the adjustable DC power supply effectively. KINDLY REMIND - For safety considerations, the DC power supply comes with only 110V input which meets the US standard voltage. 220V input is NOT available for this bench power supply
- 5V 2A USB Port, Intelligent Cooling Fan: Complaining about mobile phones or repaired devices not being charged in time? The NICE-POWER adjustable DC power supply allows you to avoid this dilemma. The variable power supply has built-in 5V 2A USB charging interface which can quickly charge any USB devices anytime. The adjustable power supply features with intelligent temperature-controlled fan and heat sink for excellent heat dissipation when the working temperature of the switching power supply exceeds 122℉/50℃, greatly reduce working noise and improving the DC regulated power supplies working efficiency and lifespan
- Compact Design, Lightweight and Portable: The DC voltage stabilized power supplies adopt stable vertical design with the shock-absorbing rubber feet on the bottom of bench supply, making it safer and more stable when using. The size of adjustable DC power supply is 8.4*3.3*5.5 inches and the lab power supply weighs only 2.6 lbs, which is very light and portable. You can carry your bench supply in and out of various workplaces
- Various Applications: This benchtop power supply is suitable for electronics repair, communication equipment maintenance, electrolysis, electroplating, brush plating, lamp test, aging test, burn-in test, production line test, DIY, labs, schools, laboratories scientific research and teaching etc. The NICE-POWER DC power supply is a nice choice for beginners or professional electricians and DIY electronics hobbyist
- Quality Assurance, Customer Service: Purchasing from NICE-POWER, you will get DC power supply variable 30V 10A*1, output power cord*1, input power cord*1, user manual*1, efficient after-sales service and technical support. We will inspect all lab power supplies and accessories before shipment to ensure that the quality of the adjustable switching DC regulated bench power supply received by each customer is good. If you have any questions about our variable power supply, please let us know without hesitation, we will response back within 24 hours
- Stable Output, C.V./C.C. Automatic Conversion: This variable DC power supply is a low noise, low ripple adjustable continuous output power supply that can work at full load for a long period of time. The bench power supply can be used as a constant-voltage (C.V.) power supply and constant-current (C.C.) power supply even when the load is changed. The constant voltage/current mode can automatically switch with load changes, you can check the working status indicator on the LED display
- Front Power Switch, Precise Coarse & Fine Adjustment Knobs: Upgrade from the old-fashion switching power supply, the brand new version power switch is on the front of DC regulated power supplies, you do not need to turn to the back to turn on/off the adjustable switching regulated power supply, easy and convenient to use. The adjustable switching DC regulated bench power supply features with potentiometer coarse and fine voltage/current adjustment knobs, you can set the desired voltage and current on NICE-POWER bench supply effortlessly
