DC Adapter 4.5mm to 5.5mm Connector

This DC power adapter converts a 4.5mm x 3.0mm male plug to a 5.5mm x 2.1mm female jack. It suits users needing to connect a power source with a smaller barrel tip to a device requiring the larger 5.5mm x 2.1mm standard. The compact blue housing measures 45mm by 12.5mm. It is sold new as a single connector piece.

Ideal for CCTV and Small Electronics Projects

This adapter fits installers extending or repairing cables for CCTV cameras and similar low-voltage devices. It also serves hobbyists building custom power leads for small electronics projects. Buyers needing a 5.5mm x 2.5mm male input or a different gender configuration should look at other connector types. It does not carry data signals or support high-current applications beyond typical DC power limits.

Fits Into Custom Cable Builds and Repairs

Use this adapter to join an existing 4.5mm x 3.0mm power lead to a 5.5mm x 2.1mm device socket without soldering. It frees you from sourcing a specific fixed-length cable when only the tip size mismatches. The simple male-to-female design adds minimal bulk to the connection point. Ensure your power supply voltage and polarity match the device requirements before connecting.

Questions about this item

What device needs a 4.5 mm x 3.0 mm male plug so this adapter can connect it?

Any power supply or cable that already has a 4.5 mm x 3.0 mm male tip can plug into the adapter's male side, letting you feed a 5.5 mm x 2.1 mm female jack.

Will a 5.5 mm x 2.5 mm barrel jack fit the female side of this adapter?

No, the female socket is 5.5 mm x 2.1 mm, so a 2.5 mm centre pin is too large and will not make contact.

How can I confirm the adapter is passing power after I plug it in?

The connected device should power on normally; you can also measure voltage at the female jack with a multimeter to verify continuity.
