DC power adapter 5.5 mm x 2.1 mm to 3.5 mm x 1.35 mm
This pack contains five identical adapters that convert a 5.5 mm by 2.1 mm male barrel plug into a 3.5 mm by 1.35 mm female jack. They are intended for anyone who needs to connect a power source with the larger barrel to a device that accepts the smaller jack. Typical uses include laptops, CCTV cameras, LED strip lighting, routers and similar low-voltage electronics.
Passive connector with no active cooling
The adapters are passive components, so they generate no heat of their own and produce no audible noise during operation. Power draw is determined entirely by the connected supply and load; the adapter itself adds no measurable consumption. Because there are no moving parts or electronics inside, thermal performance and acoustics are not applicable considerations.
Five-piece pack for multiple connection points
The bundle supplies five units, allowing several devices or cable runs to be adapted at once without purchasing separate packs. No software, drivers or additional accessories are included; the product is purely a mechanical converter. Having multiple adapters on hand simplifies installation where several endpoints share the same power source type.

Questions about this item
How do I connect the 5.5mm x 2.1mm male plug to my device's power input without forcing it?
Align the centre pin with the socket before pushing straight in; the outer barrel should slide smoothly over the sleeve — twisting while inserting bends the thin 2.1 mm pin.
What part of the adapter is most likely to wear out first with repeated plugging and unplugging?
The spring contacts inside the 3.5 mm x 1.35 mm female jack lose tension over time, causing intermittent power; keep a spare from the five-pack for quick replacement.
At what point does voltage drop become noticeable on a long cable run using these adapters?
The small 1.35 mm centre pin adds resistance, so on thin cables the drop appears first under sustained loads above a few amps — keep cable lengths short.
