Product information

Description

ProXtend DCDONGLE-7450-5517-AC is a compact DC adapter dongle that converts a 7.4 mm power plug to a 5.5 mm plug, providing a passive and reliable connection between mismatched barrel sizes. The adapter enables use of an existing power supply with devices that require a 5.5 mm input when only a 7.4 mm plug is available, maintaining the original polarity and offering a quick mechanical fit without electronics or voltage conversion.

Advantages

This dongle offers a simple and space-saving solution for matching incompatible DC barrel connectors, avoiding the need to replace power supplies or device cables. Its passive design preserves the supplied voltage and polarity, and the solid construction ensures stable contact and minimal insertion play. The adapter is lightweight and portable, suitable for carrying with laptop chargers or network equipment power supplies.

Suitable for

  • Connecting a power supply with a 7.4 mm plug to devices requiring a 5.5 mm DC input
  • Temporary power solutions for laptops, routers and POS equipment
  • Field repairs, testing and setup where matching barrel sizes is necessary

Key specifications

  • Input barrel diameter: 7.4 mm
  • Output barrel diameter: 5.5 mm
  • Connector type: DC barrel adapter (male to female conversion)
  • Design: passive, no voltage conversion or active electronics
  • Typical use: DC power signal only; maintains existing voltage and polarity
  • Construction: compact, lightweight mechanical adapter

How to use

Insert the 7.4 mm plug of the power supply into the adapter’s 7.4 mm receptacle until it seats firmly. Plug the adapter’s 5.5 mm output into the device’s DC input jack, ensuring correct polarity and a snug fit. Verify that the device powers on and operates normally; if the device does not power, disconnect and recheck connections and voltage compatibility. Do not attempt to use the adapter with power supplies that exceed the device’s rated voltage or current.

Usage recommendations

Use the adapter only when the power supply voltage and polarity match the device requirements. Avoid forcing connectors or using the adapter with loose or damaged jacks. For permanent installations or where electrical safety certification is required, consider using a dedicated compatible power adapter or professionally fitted cable.
