5.5 mm to 3.5 mm DC converter cable
This 15 cm cable converts a 5.5 mm by 2.1 mm female barrel jack into a 3.5 mm by 1.35 mm male plug with a centre pin. It lets owners of power supplies fitted with the larger tip power devices that require the smaller connector. The short length keeps the adapter close to the socket without adding bulk. Buyers needing a longer reach or a different tip polarity will need another solution.
Build and daily use
The moulded connectors and 5.9 inch cable are lightweight and flexible for desk or travel use. A female 5.5 mm jack accepts the charger tip securely while the male 3.5 mm plug inserts into the device port. No screws or latches are present so the connection relies on friction alone. Users who need a locking or right‑angled connector should look elsewhere.
Practical limits of the barrel interface
The cable passes whatever voltage and current the source and load negotiate; it adds no regulation or protection. Polarity follows the centre‑pin convention of both tips so mismatched polarity will not be corrected. The 15 cm length introduces minimal voltage drop but offers no strain relief beyond the moulded boots. Installations that require in‑wall rating or high‑current certification are not supported.

Questions about this item
What barrel size does the 5.5 mm × 2.1 mm female input accept?
The input side is a 5.5 mm outer diameter by 2.1 mm inner diameter female barrel connector that mates with a matching male plug on your power supply.
How much clearance does the 15 cm cable need behind the device?
The total length is 15 cm (5.9 in), so allow roughly that much straight run from the device’s power jack to the adapter body.
Which end do I plug into the AC adapter and which into the device?
Connect the 5.5 mm × 2.1 mm female end to your AC adapter’s male tip, then insert the 3.5 mm × 1.35 mm male end into the device’s power jack.
