## Long description

ProXtend DCDONGLE-7450-4817-H is a compact DC adapter dongle that converts a 7.4 mm barrel connector to a 4.8 mm barrel connector, enabling devices and power supplies with different barrel sizes to connect without replacing cables or chargers. The adapter provides a simple mechanical interface for power delivery and is suitable for quick swaps between compatible equipment such as laptops, routers and other electronics that use these DC barrel sizes. Its small form factor keeps the connection neat and portable while maintaining direct power transmission between the host cable and the target device.
Advantages
The dongle offers a straightforward plug-and-play conversion between 7.4 mm and 4.8 mm DC barrel connectors, eliminating the need for multiple chargers or custom cables. Its compact construction allows for easy storage and transport and permits fast connection changes during field use or maintenance. The adapter preserves the polarity and physical fit of barrel-style DC plugs and minimizes additional bulk at the power input of the target device.
Suitable for
Connecting a power supply with a 7.4 mm barrel plug to a device with a 4.8 mm barrel jack
Temporary power solutions during repairs, testing or diagnostics
Field technicians who need quick adapter swaps between different equipment
Consolidating chargers when multiple devices require different barrel sizes
Key specifications
Input connector: 7.4 mm DC barrel plug (male)
Output connector: 4.8 mm DC barrel jack (female)
Connector type: Barrel (coaxial) DC power adapter
Form factor: Inline dongle, compact and portable
Material: Durable plastic housing with metal contacts for electrical connection
Polarity: Matches standard centre-positive or centre-negative layouts as per connected devices (preserve device polarity when in use)
How to use
Insert the 7.4 mm barrel plug from your power supply into the dongle’s 7.4 mm input until it seats securely, then plug the 4.8 mm end of the dongle into the device’s DC input jack. Confirm that the power supply voltage and polarity match the requirements of the target device before connecting. Use the dongle only for making a mechanical connection between compatible barrel sizes; it does not convert voltage or provide surge protection. Remove the adapter by pulling straight out on the connector to avoid bending the barrel ends.
Usage recommendations
Verify voltage and polarity compatibility before each use, avoid excessive bending or leverage on the connected plug, and store the dongle in a dry, dust-free place when not in use to maintain reliable connections and long-term performance.
