12V 3A AC Adapter for 36W Devices

This BASEUS power supply delivers 12 volts at up to 3 amps for a maximum of 36 watts. It suits devices such as LED strips, routers, CCTV cameras, digital pianos and other equipment that uses a 5.5 mm barrel connector and requires DC12V input.

Plug-and-play with polarity check

The unit accepts 100 to 240 volts AC at 50 or 60 hertz and provides a 5.5 mm by 2.5 mm DC plug that also fits 5.5 mm by 2.1 mm sockets. Polarity is inner positive and outer negative; reversing it will prevent operation or cause damage.

Verify socket size, voltage and current draw

Confirm your device uses a 5.5 mm barrel jack with 2.1 mm or 2.5 mm centre pin and requires exactly 12 volts DC. Ensure its maximum current draw does not exceed 3 amps and that the polarity marking matches inner positive before ordering.

Questions about this item

How can I verify the adapter is delivering 12V 3A after plugging it in?

Use a multimeter on the 5.5 mm x 2.5 mm plug to confirm the inner pin reads +12 V and the outer sleeve reads ground while the connected device draws up to 3 A.

What comes in the box and which cables must I provide?

The package contains the 36 W AC adapter with a fixed 5.5 mm x 2.5 mm DC plug; you must supply the AC mains cord and ensure your device uses the same 5.5 mm x 2.5 mm or 2.1 mm jack with inner-positive polarity.

Which version should I choose if my device draws 2.5 A at 12 V?

The single 12 V 3 A model covers 0–36 W loads, so it safely powers a 2.5 A device without needing a higher-capacity variant.
