Pros & Cons

Pros

✓ High-res 4-digit LED shows 0.01V / 0.001A readout for volts, amps and watts
✓ Wide 0-30V and 0-10A range with coarse plus fine adjustment knobs
✓ OUTPUT key presets voltage/current without powering the load
✓ Built-in 5V/2A USB port charges phones and USB devices directly
✓ Eight protections: over-voltage, over-current, over-temp, short-circuit

Cons

✗ 110V US input only - no 220V support for international users
✗ Switching design - more ripple than linear supplies for analog work
✗ Fan idles until 122F/50C - little airflow during light loads
✗ Single output channel - can't drive two voltage rails at once

SpecPicks Verdict

Key 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
