DC Power Adapter Reduction WT-2.5/GT-55 2.1mm to 2.5mm plug converter

DC Power Adapter Reduction WT-2.5/GT-55 2.1mm to 2.5mm plug converter is an inline adapter that converts a 2.1 mm DC plug into a 2.5 mm DC socket. It is intended to be fitted between an existing power cable or charger and a device that requires a larger barrel connector. The adapter preserves the original power supply while allowing compatibility with equipment that uses a 2.5 mm input.

Advantages

The adapter provides a compact and lightweight solution to connect devices with differing barrel sizes without modifying the original charger or cable. It maintains the existing polarity and the continuity of the power line, allowing quick and reversible connections. Its simple construction makes it suitable for field use and for temporary or permanent setups where replacing the entire power supply is impractical.

Suitable for

• Small electronics with 2.5 mm DC input
• Routers and network equipment requiring a 2.5 mm barrel
• CCTV cameras and surveillance devices with 2.5 mm jacks
• Powering audio devices or LED drivers that accept 2.5 mm plugs
• Testing, prototyping and temporary power connections

Key specifications

• Function: converts 2.1 mm DC plug to 2.5 mm DC socket
• Connection type: barrel/plug adapter, inline
• Outer barrel diameter: accepts 2.5 mm plug
• Inner pin diameter: compatible with 2.1 mm plug
• Polarity: preserves original plug polarity (center positive or negative as per source)
• Construction: compact, low-profile inline adapter
• Typical use environment: indoor electronic devices and equipment

How to use

Insert the 2.1 mm DC plug from the existing power supply into the adapter's 2.1 mm receptacle. Then connect the 2.5 mm plug end of the adapter to the device requiring a 2.5 mm input. Ensure the plug seats fully and check that the device powers on as expected. Verify the power supply voltage and polarity before connecting to prevent damage to the device.

Usage recommendations

Use the adapter only with compatible voltage and polarity. Avoid forcing connectors and inspect the adapter for wear or damage before use. For permanent installations or higher current demands, consider using a dedicated power supply with the correct barrel size and rating.
