12 V 5 A desktop adapter for low-power 12 V

The YOOFONE 12V5A-BK converts 100–240 V AC mains to a regulated 12 V DC output rated at 5 A maximum. It accepts any device that draws 5 A or less, including typical LED strips, CCTV cameras, routers and small DC motors. The barrel plug measures 5.5 mm outer diameter with a 2.1–2.5 mm centre pin and positive-centre polarity. A screw-terminal female barrel connector is included for tool-free wiring.

Silent convection cooling with full protection suite

The unit operates from 0 to 40 °C with no fan, relying on its ABS enclosure for passive heat dissipation. Built-in safeguards cover short-circuit, over-voltage, over-current, overload and over-temperature events, cutting output automatically when a fault is detected. The supply produces no audible noise and presents no fire or explosion hazard under normal use.

Screw-terminal barrel plug speeds installation

The bundled female DC barrel connector lets installers secure bare wires by tightening screws instead of soldering, reducing assembly time for LED strips, 3D printers or security systems. No software or configuration is required; the adapter is ready to use once the polarity and voltage requirements of the load are verified.

Questions about this item

How do I connect the 5.5 mm by 2.1 mm barrel plug to my LED strip without soldering?

The adapter includes a female DC barrel connector with screw terminals. Strip the wires, insert them into the terminals matching positive to the inner pin and negative to the outer sleeve, then tighten the screws.

What maintenance does the ABS enclosure and internal protection circuitry require over time?

No scheduled maintenance is needed. Keep ventilation slots clear of dust and ensure the unit operates within the 0 to 40 °C working temperature range.

At what load does the over-current protection trip during continuous operation?

The adapter delivers up to 5 A continuously. If the connected device draws more than 5 A, the over-current cut-off activates and shuts down the output.
