Pack of Ten DC Adapters

This pack contains ten black DC power adapters that convert a 7.4 mm by 5.0 mm male plug to a 5.5 mm by 2.1 mm female jack. They suit installers and hobbyists who need to match CCTV cameras or small electronics to existing power leads.

Check Plug Dimensions First

Verify that your source cable uses a 7.4 mm by 5.0 mm male tip and that the device requires a 5.5 mm by 2.1 mm female socket. Polarity is not marked on the adapter, so confirm the centre pin wiring on both sides before connecting power.

Steady Current Path Under Load

Each adapter measures 47 mm by 13 mm by 13 mm and provides a direct metal-to-metal contact path without active components. The connection remains stable during continuous operation because there are no semiconductors or regulation circuitry to overheat or throttle.

Questions about this item

Does the pack of 10 include any cables or soldering tools, or just the DC connector tips?

Only the 10 connector tips are supplied; no wire, heat-shrink or tools are included.

How do I confirm the 7.4 mm x 5.0 mm male and 5.5 mm x 2.1 mm female sizes match my existing power lead?

Measure the outer and inner diameter of your current plug and jack; they must match 7.4 mm/5.0 mm and 5.5 mm/2.1 mm respectively.

Will the 47 mm overall length add noticeable bulk between my CCTV camera and its power supply?

Each adapter is 47 mm long, adding less than 5 cm to the cable run — generally negligible for fixed installations.
