DC power extension dongle ProXtend DCDONGLE-5525-5517-AC 5.5mm to 5.5mm

ProXtend DCDONGLE-5525-5517-AC is a DC power extension dongle with 5.5 mm to 5.5 mm connector ends that extends the reach of compatible external power adapters and devices with standard 5.5 mm DC jacks. The adapter preserves connector polarity and provides a simple, low-profile connection for power delivery between devices such as CCTV cameras, routers, and consumer electronics that use the common 5.5 mm DC plug format.

Advantages

This DC power extension dongle offers a compact and reliable extension solution without requiring soldering or modifying existing cables. Its standardized 5.5 mm to 5.5 mm connectors ensure compatibility with a wide range of devices and power supplies that use the common barrel plug size. The connector design maintains polarity and physical fit, simplifying installations and reducing cable clutter while preserving electrical continuity.

Suitable for

• Extending power to CCTV cameras and PTZ cameras
• Connecting routers, modems and network equipment to remote power supplies
• Powering consumer electronics such as audio equipment and small appliances with 5.5 mm DC jacks
• Temporary or semi-permanent setups where cable length needs to be increased

Key specifications

• Connector type: 5.5 mm barrel plug to 5.5 mm barrel socket
• Polarity: maintains standard center-positive wiring (preserves existing polarity)
• Application: DC power extension for low-voltage devices
• Form factor: inline dongle with low-profile barrel connectors
• Typical use voltage/current range: suited for common low-voltage adapter outputs (consumer and security devices)

How to use

Insert the 5.5 mm male end of the dongle into the female DC jack of the power supply or adapter, then plug the 5.5 mm female end of the dongle onto the male plug of the target device. Ensure connectors are fully seated and check that the device powers on. Verify the adapter voltage and polarity match the device requirements before connecting to avoid damage.

Usage recommendations

Use this dongle only with devices and adapters that share the same 5.5 mm connector size and compatible voltage/polarity specifications. Avoid excessive bending or strain on the dongle and connectors; route cables to prevent sharp bends and secure connections for stable power delivery.
