Power supply for 12 V devices

This BASEUS AC adapter delivers 12 V at up to 2 A with a maximum output of 24 W. It accepts a universal 100-240 V input at 50-60 Hz, making it suitable for CCTV cameras, LED strip lights, routers, Bluetooth speakers and other 12 V equipment drawing less than 24 W.

Thermals and protection

A built-in smart chip provides automatic cut-off for overload, over-voltage, over-temperature and short-circuit conditions. The adapter runs from a standard US wall plug and maintains stable output across the 0-2000 mA range without requiring active cooling.

5.5 mm x 2.5 mm barrel connector

The centre-positive DC barrel plug fits devices with a 5.5 mm outer diameter and 2.5 mm inner diameter. This single connector replaces lost or damaged power cords for compatible security cameras, WS2811 LED pixel lights, keyboards and DIY projects.

Questions about this item

How do I connect the 5.5 mm by 2.5 mm barrel plug to my CCTV camera?

Align the centre-positive tip with the camera's DC jack and push firmly until it seats; the universal 100-240 V 50-60 Hz input means you only need a standard wall outlet, no extra wiring.

Will the internal protection chip need replacement after extended use?

The built-in overload, over-voltage, over-temperature and short-circuit cut-offs are self-resetting solid-state circuits; they do not wear out and require no scheduled replacement.

At what load does the adapter hit its thermal limit first during continuous operation?

The 24 W maximum output at 12 V 2 A is the ceiling; sustained loads above 2 A trigger the over-temperature cut-off before any other protection activates.
