12V 3A AC adapter for 12 volt devices

This BASEUS adapter converts 100V-240V mains power into a regulated 12V 3A DC output. It fits equipment drawing from .1A up to 3A, covering 100mA through 3000mA loads. The self-adapting barrel jack accepts both 5.5mm x 2.1mm and 2.5mm centre-positive ports. A 3.3ft cord connects the brick to the device.

Replaces fixed-current 12V bricks up to 3A

Swap out any 12V supply rated at 1A, 1.5A, 2A or 2.5A when the original unit fails or is lost. The wide input range handles 50Hz and 60Hz grids worldwide without a voltage switch. The jump is worth it when one adjustable adapter covers several devices instead of keeping multiple fixed-current units.

Built-in protection maintains output during

Short-circuit, over-current, over-voltage and over-temperature circuits engage automatically under continuous load. The adapter suits CCTV cameras, LED strips, keyboards, speakers, routers and similar 12V electronics running for long periods. Intelligent identification matches the exact current the connected device requests up to the 3A limit.

Questions about this item

What barrel-plug sizes does the 12 V 3 A adapter fit?

The self-adapting jack accepts 5.5 mm x 2.1 mm and also works with 2.5 mm centre-positive plugs.

What is the mains voltage range and how do I connect it?

Input is 100 V-240 V at 50/60 Hz; plug the IEC lead into a wall socket then insert the barrel tip into the device.

Does the 3.3 ft cord or the adapter itself need periodic replacement?

The unit has built-in short-circuit, over-current, over-voltage and over-temperature protection, so only the cord would need replacing if it becomes damaged.
