12 V 1 A AC adapter with dual barrel plugs

This BASEUS power supply delivers a fixed 12 V output at up to 1 A, providing a maximum of 12 W. It accepts a universal 100-240 V AC input at 50/60 Hz. The cable terminates in a 5.5 mm barrel connector that includes interchangeable 2.5 mm and 2.1 mm centre pins for broad device compatibility.

Works only with devices that need exactly 12 V

The adapter cannot supply voltages other than 12 V and will not safely power equipment requiring more than 1 A. Current delivery is limited to values from 0.1 A up to the 1 A ceiling, so higher-draw loads will trigger the built-in overload and short-circuit protections. Polarity and plug dimensions must match the device exactly before connection.

Replaces lost or failed 12 V 1 A bricks

It serves as a direct substitute for original adapters supplied with CCTV cameras, DVR or NVR recorders, 12 V LED strip lights such as 2835, 5050 or WS2811 types, routers, speakers, scanners and similar low-power gear. The jump is worthwhile when the original unit is missing, damaged or lacks the over-voltage and over-current safeguards integrated into this model.

Questions about this item

Should I choose the 5.5 mm × 2.5 mm or 5.5 mm × 2.1 mm plug for my device?

The adapter ships with both 5.5 mm × 2.5 mm and 5.5 mm × 2.1 mm tips; match the tip to the socket on your CCTV camera, LED strip, router or other 12 V equipment.

What does the 12 W rating mean when the adapter is powering a router or LED strip?

It delivers a steady 12 V at up to 1 A, so any device drawing 0.1 A to 1 A at 12 V — such as a router, speaker or 12 V LED strip — will run within its 12 W limit.

How does the 100–240 V 50/60 Hz input affect use in different regions?

The wide-range input accepts mains voltages from 100 V to 240 V at 50 Hz or 60 Hz, letting you plug the same adapter into sockets worldwide without a voltage converter.
