Questions about this item

Does the adapter include the 5.5×2.1 mm barrel plug and the 1-to-4 splitter, or must they be purchased separately?

The package supplies the AC/DC adapter with a fixed 5.5×2.1 mm centre-positive barrel connector and a 1-to-4 power splitter cable, so no extra cables are required for typical 12 V devices.

The listing mentions Level VI efficiency and a 30 W maximum — which version should I choose for a device that draws 1.5 A at 12 V?

The single 12 V 2.5 A model delivers up to 30 W and automatically adjusts output from 50 mA to 2.5 A, so it covers a 1.5 A load without needing a different capacity.

What does the 30 W rating mean when the adapter is powering a CCTV camera that needs 12 V 1 A?

The 30 W figure is the maximum continuous power the unit can supply; at 12 V 1 A the camera draws only 12 W, well within the adapter’s capability, and the intelligent adjustment provides exactly the current requested.
