5V 4A (4000mA) switching power supply - UL Listed
This UL-listed switching power supply delivers a clean, regulated 5V DC output at up to 4A (4,000mA / 20W) via a standard 5.5×2.1mm centre-positive DC barrel jack. It accepts 110–240V AC input and is ideal for powering LED matrices, NeoPixel strips, and other high-current 5V projects.
Key Features
- Output – 5V DC at up to 4A (20W)
- Connector – 5.5mm OD / 2.1mm ID centre-positive DC barrel jack
- Input – 110–240V AC (universal)
- Certifications – FCC, CE, UL listed
- Stable Output – Minimal voltage droop at high currents
Compatible Accessories
- 2.1mm Barrel Jack Extension Cable (1.5m)
- Breadboard-Friendly 2.1mm DC Barrel Jack
- 2.1mm DC Barrel Jack to Alligator Clips
- 4-Way 2.1mm DC Barrel Jack Splitter
Ideal For
- RGB LED matrices and NeoPixel projects
- Addressable LED strips (WS2812B, LPD8806, etc.)
- High-current 5V devices and multi-motor setups
Package Contents
- 1Ă— 5V 4A Switching Power Supply (US plug, 5.5Ă—2.1mm DC barrel jack)
Important: This supply ships with a US 2-prong plug. A plug adapter or replacement figure-8 (IEC C7) cable is required for use in Australia.
Note: This supply is not suitable for powering an Arduino via its DC jack, as the Arduino's onboard regulator requires at least 7.5V input.
