SMUGDESK 2PCS 5.5mm x 2.1mm Female to 3.0mm x 1.1mm Male DC Power Adapter Cord

Two-piece 5.5 mm × 2.1 mm to 3.0 mm × 1.1 mm DC

This pair of converter cables bridges a 5.5 mm × 2.1 mm female jack to a 3.0 mm × 1.1 mm male plug. Each cord lets you power equipment that expects the smaller barrel size from a supply fitted with the larger one. The twin pack suits workshops or home labs where several devices share the same mismatch.

Steady current through the conductive core under

The high-quality wire core maintains stable current transmission during extended operation, reducing the chance of power flicker or unexpected shutdowns. Precise plug dimensions keep contact tight so vibration does not loosen the connection. The insulating jacket resists wear and preserves insulation performance over long periods.

Compact barrels and dual cables simplify

Both ends use standard barrel profiles — 5.5 mm × 2.1 mm female and 3.0 mm × 1.1 mm male — so they slot into existing router, CCTV camera, LED strip or small monitor ports without adapters. Two cables in the pack let you equip a pair of devices at once, keeping bench clutter low. No latch or locking mechanism is present, so the fit relies on friction alone.
