ProXtend DCDONGLE-5525-4530-D is a compact DC adapter dongle that converts a 5.5 mm barrel connector to a 4.5 mm plug, enabling compatibility between power supplies and devices that use different outer and inner diameters. The adapter provides a simple mechanical connection without modifying the cables or connectors, allowing quick and reversible adaptation for a range of electronics including laptops, routers and cameras.

Advantages

The adapter is lightweight and portable, making it easy to carry with a power supply or in a tool kit. Its straightforward design provides a secure fit between a 5.5 mm barrel and a 4.5 mm plug, reducing the need to replace chargers or buy new cables. The product requires no tools to attach and detaches easily when not needed, offering a practical solution when standard connectors are incompatible.

Suitable for

• Connecting a 5.5 mm barrel power output to devices with a 4.5 mm input
• Temporary power solutions for laptops and notebook chargers
• Compatibility adjustments for routers, network equipment and modems
• Powering cameras, monitors and other small electronics with differing DC jack sizes

Key specifications

How to use

Align the 5.5 mm barrel connector from the power supply with the adapter’s input and push until it seats firmly. Insert the adapter’s 4.5 mm plug into the device power jack, ensuring correct polarity and a secure connection. Check that the power supply voltage and polarity match the device requirements before applying power. When finished, pull the adapter straight out to disconnect; no tools are required.

Usage recommendations

Verify device voltage and polarity compatibility before use and avoid forcing connectors. Use the adapter for temporary or occasional adaptation; for long-term installations, consider a dedicated compatible cable or power supply rated for the device.
