  • TypeAC Adapters
  • Powers devices from 3V to 12V with a single adapter
  • Includes eight interchangeable DC tips for broad device compatibility

Universal 12W AC/DC Adapter

This 12W universal adapter supplies selectable DC voltages from 3V to 12V at up to 1000mA. It targets owners of household electronics such as routers, TV boxes, tablets, MP3 players and CCTV cameras that require a centre-positive barrel connector. The unit accepts 100V to 240V AC input at 50Hz or 60Hz for worldwide use.

Plug Selection and Polarity Checks

Eight interchangeable tips cover diameters of 2.5mm, 3.0mm, 3.5mm, 4.0mm, 4.8mm and 5.5mm with various pin sizes. Installation is a matter of choosing the tip that matches the device jack and sliding it onto the cable. The fixed centre-positive polarity cannot be reversed, so devices with centre-negative jacks will not work. Users must verify both dimensions and polarity before connecting.

Power Limits and Device Compatibility

The adapter delivers a maximum of 12W and 1A, comfortably running devices rated at 100mA, 200mA, 500mA or 800mA. It will not support equipment that draws more than 1A or exceeds 12W, nor will it suit devices requiring a different voltage range or polarity. Always confirm the appliance's input specifications against the adapter's fixed output capabilities.

Questions about this item

How do I verify the adapter is working correctly after setup?

Connect the correct tip for your device, set the voltage selector to match the required output between 3V and 12V, and confirm the device powers on; the adapter supplies up to 1000mA at 12W maximum.

What comes in the box and what must I purchase separately?

The package includes the power adapter, a kit with eight DC tips (2.5×0.7 mm, 3.0×1.1 mm, 3.5×1.35 mm, 4.0×1.7 mm, 4.8×1.7 mm, 5.5×2.1 mm, 5.5×2.5 mm, 3.5 mm mono), a switch key, and a manual; no extra items are required for basic operation.

Which voltage setting and tip should I choose for my device?

Match the adapter's output voltage (3V, 4.5V, 5V, 6V, 7.5V, 9V, or 12V) to your device's input specification, then select the tip that fits the DC jack dimensions exactly; polarity is fixed centre-positive.
