Universal AC adapter for small electronics

This 12W switching supply delivers selectable output from 3V to 12V at up to 1A, covering routers, speakers, CCTV cameras and LED strips. Eight interchangeable barrel plugs plus a Micro USB tip handle the most common 5.5x2.1mm, 5.5x2.5mm and smaller connector sizes found on household devices. Inner-positive polarity matches the majority of centre-positive equipment. It is not a laptop charger and cannot power toy cars or battery chargers.

Steady 12W output across the voltage range

The adapter maintains its full 12W rating whether set to 3V, 4.5V, 5V, 6V, 7.5V, 9V or 12V, so sustained loads do not force a drop to a lower wattage at higher voltages. Input accepts 110-240V at 50/60Hz, making it suitable for worldwide mains without a separate voltage selector. The fixed 1A current limit means devices drawing more than 1A at any setting will not operate reliably.

Polarity and plug fit decide compatibility

Inner-positive, outer-negative barrel polarity is mandatory; equipment requiring the opposite polarity will not work and could be damaged. The supplied tips cover 5.5x2.1mm, 5.5x2.5mm, 4.8x1.7mm, 4.0x1.7mm, 3.5x1.35mm, 3.0x1.0mm, 2.5x0.7mm and Micro USB, so the single specification that determines fit is whether your device uses one of those exact connector sizes with centre-positive wiring.

Questions about this item

Does the 12W adapter run hot or make noise when powering a router all day?

The 12W switching supply stays cool and silent during continuous use because it only draws the current your device needs up to 1Amp at the selected voltage.

What must I already own to use the 5.5x2.1mm tip with my CCTV camera?

You need a device that accepts 5.5x2.1mm centre-positive DC input and operates at one of the seven voltages between 3V and 12V.

Will the 5.5x2.5mm extended tip fit the 5.5x2.1mm jack on my older LED strip?

No, the 5.5x2.5mm plug has a larger inner diameter and will not make reliable contact with a 5.5x2.1mm socket.
