Converter Cable for Barrel Plugs

This 17 cm DC converter cable bridges a 5.5×2.1 mm female jack to a 5.5×2.5 mm male plug with centre pin. It lets you power devices that require the larger tip using an adapter fitted with the smaller barrel. The pack contains three identical cables for spare or multi-device use.

Passive Adaptor — No Active Components

The cable carries only copper conductors and moulded connectors, so it adds no active circuitry, no fan and no semiconductor junctions. Power draw and thermal output are therefore identical to the source adapter, and the cable itself generates no audible noise. Voltage and current limits are defined entirely by the power supply you attach.

Sustained Use Within Adapter Rating

Because the adaptor is passive, its behaviour under continuous load matches the rating of the connected power supply and the connector contact area. No derating or thermal throttle occurs inside the cable itself. Ensure the supply’s output current stays within the 5.5×2.5 mm plug’s design limits for reliable long-term operation.

Questions about this item

How do I connect the 5.5×2.1mm female end to my AC adapter without reversing the polarity?

Align the centre pin of the adapter tip with the female socket and push straight in until it seats; the 17cm cable then presents a 5.5×2.5mm male plug for your device.

Will the 5.5×2.5mm male connector wear out and need replacement after repeated insertions?

The gold-plated pins resist oxidation, so under normal daily use the connector should last for years without requiring replacement.

What is the practical current limit before the 17cm cable becomes a bottleneck under sustained load?

The 17cm length keeps voltage drop low, so the limiting factor is the 5.5×2.1mm female socket rating rather than the cable itself.
