What these adapters do
This pack contains four DC power adapters that convert a 7.4mm x 5.0mm male plug into a 5.5mm x 2.1mm female socket. They suit hobbyists, technicians and installers who need to match a barrel connector on a power supply to a device with the smaller 5.5mm x 2.1mm input.
How they fit into a project
Each adapter measures 47mm x 13mm x 13mm so it sits inline without adding bulk. No soldering or tools are required; simply push the male end into the source cable and plug the device into the female side. The black housing blends with typical CCTV or small-electronics wiring.
Behaviour under continuous use
The solid metal contacts maintain a stable connection while the moulded body resists heat from sustained current flow. Because the adapter is passive, its reliability depends on the quality of the cables and power supply used with it. It is not suited for applications that demand a locking or waterproof barrel connector.

Questions about this item
How much current can the 7.4mm x 5.0mm male plug handle before it overheats?
The adapter uses a 7.4mm x 5.0mm male to 5.5mm x 2.1mm female barrel connector rated for typical low-voltage DC applications.
Do the adapters get warm or make noise when powering a CCTV camera continuously?
These are passive barrel connectors with no active electronics, so they produce no noise and negligible heat during continuous operation.
What cable diameter fits the 5.5mm x 2.1mm female jack on these adapters?
The female jack accepts a standard 5.5mm outer diameter and 2.1mm inner diameter male barrel plug.
