  • TypePower
  • Converts 5.5mm x 1.7mm male to 5.5mm x 2.1mm female for wider device compatibility
  • Four adapters per pack provide spares for multiple installations or future repairs
  • Compact 41mm length fits tight enclosures without adding bulk

Connector Sizing for DC Devices

This pack contains four DC power adapters that convert a 5.5mm x 1.7mm male plug into a 5.5mm x 2.1mm female socket. They suit hobbyists repairing cables or installers connecting CCTV cameras and similar low-voltage equipment. The yellow colour helps identify the adapter in a tool bag or behind a rack.

Check Plug Dimensions Before Buying

Verify that your existing power supply terminates in a 5.5mm x 1.7mm male barrel and that the device you are powering accepts a 5.5mm x 2.1mm female barrel. The adapter body measures 41mm long by 12.5mm in diameter so confirm there is physical clearance at the connection point. Polarity is not altered by this passive connector.

Four-Pack Enables Multiple Installs

Supplied as a set of four identical tips, the bundle lets you prepare several cable runs or keep spares for field repairs. No software, drivers or additional hardware are included; the adapters are purely mechanical connectors for extending or repairing DC power leads.
