Universal AC adapter kit

This 24 W universal AC adapter converts 100 to 240 V mains input into selectable DC output from 3 V to 12 V at up to 2 A. It ships with eight interchangeable barrel plugs and a Micro USB connector for 5.5 × 2.1 mm centre-positive devices.

Sustained-load behaviour

Built-in over-voltage, over-current, short-circuit and over-temperature protection keeps the unit stable during continuous operation. The compact housing maintains high energy-conversion efficiency across the full 3 V to 12 V range without thermal throttling.

Replaces fixed-voltage wall warts

The kit replaces multiple single-voltage power supplies for routers, speakers, CCTV cameras and LED strips. It is not suitable for laptops, toy cars or battery chargers, and polarity must match centre-positive only.

Questions about this item

Does the 24W adapter run hot or make noise when powering a router all day?

The unit uses high-efficiency conversion and built-in over-temperature protection, so it stays cool and silent during continuous 24W loads.

What must I already have to use the 5.5x2.1mm plug with my device?

Your equipment needs a 5.5mm outer, 2.1mm inner barrel jack with inner-positive polarity and a voltage requirement between 3V and 12V at up to 2A.

Will the 3V-to-12V selectable output work safely with my older 9V CCTV camera?

Yes — set the switch to 9V, confirm the camera draws 2A or less, and the adapter’s over-voltage and short-circuit guards protect the legacy gear.
