Meet the DEMASLED DC 3.3V 2A power supply, a compact and dependable source designed for small electronics. With a labeled 5.5 mm outer and 2.1 mm inner barrel, it delivers up to 6.6 W of power and supports devices that run on 3.3 V. The form factor fits neatly behind shelves, inside project enclosures, or alongside a breadboard setup, making it a practical partner for makers and hobbyists.

Designed for indoor use, this 6.6 W supply stays cool under typical loads and maintains a steady output when current remains at or below 2 A. Its durable build and secure barrel connection help reduce connection wobble during long sessions of tweaking and testing, giving you a calmer workspace while you iterate designs.

What it powers well

• LED light strips and small indoor fixtures that operate at 3.3 V
• Breadboard experiments and compact electronics projects that need a reliable power source
• Replacement adapters for missing or damaged original power supplies

Why choose this DEMASLED unit

• Secure connections thanks to the 5.5 mm outer barrel and 2.1 mm inner barrel
• Built-in protections for short circuits, overload, and overvoltage to support safe operation
