12V 2A Switching Power Adapter – 24W, 100-240V AC Input, 5.5 × 2.1 mm DC Plug, ABS

The 12V 2A Switching power adapter is a desktop-style switching power adapter that converts mains AC power into a regulated 12V DC output at up to 2A, for a maximum power rating of 24W. It accepts a wide input range of 100–240V AC at 50/60 Hz, so it can be used in most regions without a voltage selector. The output is delivered through a standard 5.5 × 2.1 mm barrel-style DC plug, which fits a very large number of routers, IP cameras, LED strip controllers, audio devices, and small network appliances. The adapter uses pulse-width modulation (PWM) switching regulation rather than a bulky iron-core transformer, which keeps the housing compact at approximately 90 × 50 × 30 mm and reduces heat generation during long runtimes. Its ABS plastic enclosure is lightweight and resistant to everyday handling, and the inline “between-way” form factor places the adapter body on the mains cable rather than occupying a wall socket directly, which helps in power strips and crowded outlets. Typical applications include CCTV cameras, modems and routers, small LED lighting installations, and bench testing of 12V electronics. This 12V 2A switching adapter is a practical replacement or spare unit for devices that require a stable, regulated 12V supply at currents up to 2A.
