Power Supply Adapter 5V 3A

High-Capacity 5V 3A DC Output: Efficiently converts household AC grid voltage into a steady, regulated 5V DC output up to 3A (15W max), serving as a reliable high-current power source for demanding 5V electronics.

Standard 5.5mm x 2.1mm Center-Positive Plug: Equipped with a universal DC barrel jack connector for seamless, plug-and-play compatibility with single-board computers, microcontroller kits, and USB power hubs.

Universal AC Input Voltage Range: Compatible with standard global electricity grids (100V–240V AC, 50/60Hz), providing versatile performance across standard wall outlets.

Compact Wall-Plug Design: Space-saving, low-profile plastic housing plugs directly into wall sockets or power strips without blocking adjacent outlets.

Silent & Energy-Efficient Performance: Solid-state fan-less design offers 100% silent operation with low standby energy consumption and smooth voltage ripple control.

Built-in Safety Protections: Integrated circuitry guards connected devices against short circuits, continuous over-current, over-voltage spikes, and thermal conditions.

Housing & Casing Style: Fully insulated, flame-retardant ABS plastic wall-mount enclosure designed for safe indoor operation.

Contact & Connector Style: EU standard 2-pin AC wall plug with an integrated DC output cable terminating in a center-positive 5.5mm x 2.1mm barrel plug.

Technical Specifications:

Input Voltage: AC 100V–240V (50/60Hz).

Output Voltage: DC 5V.

Output Current: 0A–3A Max (3000mA).

Rated Power: 15W.
