Product details

Versatile, precise power for your projects

The Meiyue Adjustable Power Supply offers a wide 3–24V voltage range with a maximum 5A output and 120W, making it a flexible companion for LED strips, micro devices, and DIY builds. The real-time LED readout helps you dial in exact voltages to match your device’s needs, reducing the risk of overvoltage or underpowering.

Key capabilities at a glance

  • Wide input: AC 100–240V, 50/60 Hz, allowing use at home, in a workshop, or while traveling with compatible outlets.
  • Adjustable DC output: 3–24V with precise control and a max of 5A to cover many small electronics.
  • Powerful yet compact: integrated design with a rotating knob for on-the-fly changes and a clear voltage display.
  • Safe by design: multiple protections including over-voltage, over-current, over-temperature, and short-circuit cut-offs.

The kit includes a comprehensive set of accessories to adapt to different devices. You get one main adapter, 14 DC plugs for common sizes, and a reversed polarity cable to connect or adapt safely to various devices. This reduces the need to buy separate power bricks for each gadget.

Two practical use scenarios

  • DIY electronics and prototyping: adjust voltage as you test sensors, microcontrollers, or LED strips.
  • Maintenance and upgrades: power printers, small hobby motors, routers, and audio gear with a stable, controllable supply.

Tips for safe operation

  • Never exceed the 120W rating or the device’s rated voltage/current. Start low and increase gradually.
  • Use the included plugs and polarity cable to match your device’s connector.
  • Keep the unit indoors and away from moisture or extreme heat.
