Four-Piece Adapter Set for CCTV
This pack contains four DC power adapters that convert a 3.5mm x 1.35mm male plug into a 5.5mm x 2.5mm female socket. They are intended for small electronics projects and CCTV camera installations where the existing power lead needs a different barrel size. Each unit is new and supplied in a red finish.
Consistent Pass-Through Without Active Electronics
The adapters contain no regulation or conversion circuitry; they simply join the centre pin and barrel of the two connector sizes. Voltage and current pass through unchanged, so the load sees the same supply characteristics as if the original plug were fitted directly. Mechanical contact pressure is maintained by the sprung barrel of the female socket.
Limited to Barrel-Connector Compatibility Only
The interface is restricted to devices that already use 3.5mm x 1.35mm male and 5.5mm x 2.5mm female DC barrel connectors. They cannot adapt screw-terminal leads, USB power delivery or any proprietary laptop power tips. Polarity follows the physical orientation of the plugs, so the installer must verify centre-positive or centre-negative wiring before connection.

Questions about this item
Does the 3.5 mm x 1.35 mm male plug draw extra power or run hot when used continuously?
These passive adapters add no active circuitry, so they do not consume additional power or generate measurable heat during all-day operation.
What must I already have for the 5.5 mm x 2.5 mm female socket to deliver power?
You need a power source fitted with a matching 5.5 mm x 2.5 mm male plug — such as a CCTV supply or bench PSU — that provides the voltage and current your device requires.
Will the 3.5 mm x 1.35 mm male end fit the barrel jack on my older router or camera?
It fits only equipment that specifies a 3.5 mm outer diameter and 1.35 mm centre pin; measure the original jack before relying on the adapter.
