What this adapter powers

This 12 V 2 A AC-to-DC supply delivers 24 W through a 5.5 mm × 2.1 mm centre-positive barrel plug. It accepts 100–240 V AC input and includes a 3.9 ft power cord, making it a direct replacement for the original brick on compatible routers, switches, CCTV cameras, LED strips and listed Yamaha keyboards.

Who it suits and who it does not

Buyers needing a 12 V 2 A source with the exact 5.5 × 2.1 mm connector for the devices named in the specifications will find a drop-in fit. It does not serve equipment that requires a different voltage, a higher current rating, a locking connector or a larger barrel diameter.

Build integration

The compact 2.9 × 2.1 × 1.1 in body sits inline on the mains lead, so it needs only a standard wall socket and a device with a matching jack. Built-in overload, thermal, short-circuit and over-voltage protection removes the need for external fusing, freeing bench space and reducing cable clutter.

Questions about this item

What connector size must my device accept for this 12V 2A adapter to fit?

The plug is a 5.5 mm outer by 2.1 mm inner barrel with centre-positive polarity, so the device jack must match those dimensions.

Will this adapter safely power a legacy router that only draws 1 A at 12 V?

Yes, the supply delivers up to 2 A but the router will draw only the current it needs, and the built-in overload and short-circuit protection guards older hardware.

How can I confirm the adapter is operating correctly once connected?

The unit has no status LED, so verify the target device powers on normally and measure 12 V at the barrel with a multimeter if required.
