## Summary description

ProXtend DCDONGLE-5525-4530-AS is a DC power adapter dongle that converts a 5.5 mm outer diameter DC plug to a 4.5 mm plug.

Use it to adapt power supplies or chargers to compatible equipment such as routers, CCTV cameras, or portable electronics where the 4.5 mm inlet is required.

## Long description

ProXtend DCDONGLE-5525-4530-AS is a compact DC power plug adapter that converts a 5.5 mm outer diameter barrel connector to a 4.5 mm barrel connector. The adapter provides a straight mechanical connection while preserving the existing polarity, enabling power supplies with common 5.5×2.1 or 5.5×2.5 plugs to feed devices that require a 4.5 mm inlet. The small form factor makes it suitable for use where space is limited or where replacing cables is impractical.
Advantages
The adapter offers a simple and reliable mechanical conversion from 5.5 mm to 4.5 mm barrel size without modifying the power source or device. It maintains electrical polarity and contact continuity, minimizing the risk of connection faults. Its compact metal/plastic construction (typical for barrel adapters) allows for repeated insertions and stable seating in common DC jacks. The straightforward design requires no tools or wiring to use.
Suitable for
Connecting chargers and power adapters to routers and modems with 4.5 mm inlets
Powering CCTV cameras and surveillance equipment that use a 4.5 mm barrel connector
Adapting portable electronics, audio equipment, or LED drivers that require a smaller DC plug
Key specifications
Input barrel outer diameter: 5.5 mm
Output barrel outer diameter: 4.5 mm
Connection type: straight DC barrel adapter
Polarity: preserves original polarity (center positive or negative as originally wired)
Construction: compact inline adapter suitable for common DC power jacks
How to use
Insert the 5.5 mm male plug of the power supply into the adapter input until it seats securely. Then plug the adapter output (4.5 mm) into the device’s DC inlet. Verify that the power supply voltage and polarity match the device requirements before connecting. No tools are required; ensure the adapter and connectors are free of debris and that connections are firm to prevent intermittent power.
Usage recommendations
Check device voltage and polarity compatibility prior to use. Avoid forcing connectors or using the adapter with damaged plugs. For outdoor or exposed installations, protect the connection from moisture and mechanical strain to ensure reliable operation.
