DC Power Adapter 4.0mm x 1.35mm Male
This new DC power adapter converts a 4.0mm x 1.35mm male plug to a 5.5mm x 2.1mm female jack. It suits small electronics projects and CCTV camera installations. The compact black connector measures 41mm x 12.5mm. Use it to extend a cable to a desired length or replace a broken connector.
Who should use this adapter
It fits setups needing a 4.0mm x 1.35mm male input and a 5.5mm x 2.1mm female output. Builders needing a different barrel size or a male-to-male gender should look elsewhere. The single piece includes no cable or additional tips.
Critical connector specification
The decisive spec is the 4.0mm x 1.35mm male to 5.5mm x 2.1mm female connector pairing. Verify your device requires this exact male tip and female barrel combination before ordering. Mismatched dimensions will prevent a secure power connection.

Questions about this item
What size DC barrel jack must my device have to accept the 4.0mm x 1.35mm male plug on this adapter?
Your device needs a 4.0mm outer diameter and 1.35mm inner diameter barrel jack to fit the male plug.
Will the 5.5mm x 2.1mm female socket on this adapter accept a 5.5mm x 2.5mm male plug from an older power supply?
No, the 2.1mm centre pin is too narrow for a 2.5mm male plug; the connection would be loose or fail.
How can I confirm the adapter is passing power correctly after I connect it?
The connected device should power on normally; you can also measure voltage at the female socket with a multimeter.
