What this adapter powers

This 12 V 1 A mains adapter converts 100-240 V AC at 50-60 Hz into regulated 12 V DC at up to 1000 mA. The barrel plug has a 5.5 mm outer and 2.1-2.5 mm inner diameter. A 1.5 m cable and a screw-terminal DIY connector are included.

Who it suits and who it does not

It suits devices that draw 12 V and stay below 12 W such as LED strips, CCTV cameras, Bluetooth speakers or small routers. The unit automatically limits current to the load up to 1 A. Buyers whose equipment needs more than 12 W or a different voltage should look elsewhere.

Installation notes

Plug the adapter into a standard Type A mains socket and connect the barrel jack to the device. The screw-terminal DIY connector lets you attach bare wires without soldering. The most common issue is a loose barrel fit if the device jack tolerances differ from 5.5 x 2.1 mm.

Questions about this item

What mains voltage range does the ALA-12V1A1.5M-BK adapter accept?

The adapter accepts 100 to 240 V AC at 50 or 60 Hz, so it works on standard household supplies worldwide without a separate voltage selector.

Will the 5.5 × 2.5 mm barrel plug with 2.1 mm centre pin fit my existing 12 V device?

Yes, the connector’s outer diameter is 5.5 mm and inner diameter is 2.1–2.5 mm, matching the common 5.5 × 2.1 mm and 5.5 × 2.5 mm barrel jacks found on many 12 V LED strips, cameras and speakers.

How can I verify the adapter is delivering the correct 12 V output after connecting it?

Measure the DC voltage at the barrel plug with a multimeter; it should read approximately 12 V when the adapter is powered and the attached device draws up to 1 A.
