Power adapter for 5.5 x 2.5mm devices
This adapter converts a 5.5 x 2.5mm male DC plug into a 3.5mm female socket. It suits users who need to connect a 3.5mm barrel jack device to a power source with a larger 5.5mm connector. The 12cm cable provides a short bridge between the two interfaces. It is a simple gender changer for DC power connections.
Fits between 5.5mm source and 3.5mm load
The male end plugs into a 5.5 x 2.5mm power output while the female end accepts a 3.5mm plug from the target device. This arrangement frees the user from sourcing a dedicated power supply with the smaller connector. The short length keeps the link tidy inside a chassis or on a desk. No additional cables or tools are required for installation.
Replaces mismatched barrel jack cables
It upgrades a setup where a 5.5mm power lead cannot directly feed a 3.5mm input. The jump is worth it when the existing power source is otherwise suitable and only the connector diameter differs. Buyers who need a different voltage, polarity or current rating will not be served by this passive adapter alone. It does not convert power characteristics, only the physical plug shape.

Questions about this item
Will the 12 cm cable handle continuous current without overheating?
The 12 cm adapter is a passive connector with no active components, so it does not generate heat during normal power delivery.
Does the 5.5 x 2.5 mm plug or 3.5 mm jack produce audible noise under load?
There are no moving parts or electronics inside, so the adapter operates silently regardless of load.
What voltage and polarity must my power supply already provide for this adapter to work?
The adapter simply passes through whatever voltage and centre-positive polarity your supply delivers; it does not convert or regulate power.
