  • 12 V 1 A output delivers steady 12 W power

ABLEGRID 12V 1A AC adapter

This ABLEGRID unit is a 12 V, 1 A DC power supply intended for devices that require a 5.5 mm outer and 2.5 mm inner barrel connector with centre-positive polarity. It suits owners of routers, small audio gear, LED strips or similar hardware that ships with a matching 12 W adapter.

Worldwide 100-240 V input range

The adapter accepts AC input from 100 V to 240 V at 50-60 Hz, so it works on mains supplies in most countries without a voltage selector. A fixed 1.2 m cable length limits placement distance from the wall socket, and the barrel tip size cannot be changed, so the connector must match the device exactly.

Centre-positive 5.5 x 2.5 mm barrel

The single specification that decides compatibility is the 5.5 mm outer diameter, 2.5 mm inner diameter barrel plug wired centre-positive; if the target device uses a different tip size, polarity or voltage, this adapter will not work. Buyers who need a different connector, higher current or adjustable voltage should look elsewhere.

Questions about this item

Should I pick the 500 mA or 1000 mA version for my device?

This unit supplies 1.0 A, so choose it when your device requires 12 V at up to 1 A; the 0.5 A rating in the listing simply shows the adapter can also run lighter loads.

What does the 12 W rating mean when I plug it into my router?

At 12 V the adapter delivers up to 1 A, giving a maximum of 12 W; your router will draw only the current it needs, so the 12 W figure is the ceiling, not the constant draw.

Does the 5.5 mm by 2.5 mm centre-positive barrel work with the AC 100-240 V input worldwide?

Yes, the input accepts 100-240 V at 50-60 Hz for global use, while the fixed 5.5 mm OD by 2.5 mm ID centre-positive plug connects to the device side.
