Description
The Mercury DC09066EU is a replacement power supply that delivers 9V DC at 660mA, giving you a straightforward way to get a device working again after its original adapter has been lost, damaged, or worn out with age. It fits with a European (EU) two-pin plug and is built to meet European electrical standards, so you get safe and dependable power without any guesswork.
This power supply, sometimes called a mains adapter or PSU, uses a DC jack (barrel connector) measuring 5.5 x 2.1mm. That size is common across a wide range of small electronics, so before you order it is worth checking the plug on your existing adapter or the socket on your device to confirm the fit. Alongside the connector size, always match the voltage and current rating to what your equipment needs, as these figures matter just as much as the physical plug.
We stock this unit as part of our wider range of EU replacement power supplies, which cover several voltage and current combinations. Whether you are keeping a piece of audio kit running, powering a small router, or replacing an adapter for another low-voltage device, the DC09066EU offers a reliable option at the 9V, 660mA rating. If you are unsure which supply suits your setup, checking the label on your original adapter is usually the quickest way to find the right match.
