12 V 2 A desktop power adapter

This 12 V 2 A AC adapter delivers up to 24 W from a 100-240 V 50/60 Hz mains supply. A 1.4 m cord ends in a 5.5 mm × 2.5 mm barrel plug that also fits 5.5 mm × 2.1 mm sockets with inner-positive polarity. It is built to power compatible 12 V DC equipment such as CCTV cameras, LED strips, routers and similar low-draw devices.

Suitable for fixed 12 V DC loads under 24 W

The unit suits installers and hobbyists who need a compact wall-mount supply for security cameras, LED pixel lighting, USB hubs, TV boxes or DIY projects drawing no more than 2 A. It is not for buyers who want to charge battery-powered laptops, phones or MacBooks, nor for devices that require a higher current or a different voltage.

24 W continuous output with 1.4 m reach

The adapter comfortably handles any 12 V load up to its 24 W rating, including WS2811 LED pixels, small hard-disk enclosures, GPS units and BT speakers. Headroom ends at the 2 A limit; equipment needing more current or a battery-charging function must use a different supply.
