DC Power Gender Changer for 5.5 x 2.5mm Connectors

This gender changer adapts a 5.5mm x 2.5mm DC power jack from female to male, extending reach by three metres. It suits installers routing power to CCTV cameras, LED strips or router equipment where the existing cable falls short. The TPE and PVC jacket protects the conductors during fixed or temporary runs.

Practical Limits of the 5.5 x 2.5mm Barrel Interface

The 5.5mm x 2.5mm barrel standard carries low-voltage DC only and has no locking mechanism, so vibration or tugging can unseat the plug. Polarity is not encoded on the connector itself; reversing tip and sleeve polarity will damage connected gear. The three-metre length adds voltage drop, so the supply must compensate for the extra resistance.

Installation Notes and Common Pitfalls

The moulded female-to-male ends push together without tools, making the physical connection straightforward. Most failures come from mismatched tip polarity or exceeding the cable’s current rating, which causes overheating at the joints. Securing the cable with ties near each connector prevents strain from pulling the plugs loose over time.

Questions about this item

Should I choose the 5.5 x 2.5mm version for my device?

Yes, select this version only if your equipment uses a 5.5mm outer and 2.5mm inner barrel connector; otherwise the plug will not fit.

What does the 3m cable length mean for my setup?

It gives you three metres of reach between the power supply and the device, allowing flexible placement without stretching the original lead.

Does the 5.5 x 2.5mm barrel connector limit the current I can draw?

The supplier rates the assembly at 8A, so the connector and 3m TPE/PVC cable together support up to eight amps of continuous DC current.
