Construction and Materials
Moulded USB Type-A plug with internal strain relief, soft PVC over-mould on the barrel socket, stranded copper cores, black PVC outer jacket. Standard USB-A pinout (VBUS / GND).
Typical Applications
Useful where a 5 V device uses a 5.5 x 2.1 mm jack but only a USB port is available — small fans, LED controllers, ESP / Arduino sensor boards with barrel jacks.
Compatibility and Fitment
USB-A host port, USB charger, or 5 V power bank supplying up to standard USB 2.0 / 3.0 current limits. The barrel socket mates with any 5.5 x 2.1 mm male plug — not for 5.5 x 2.5 mm or 4.0 x 1.7 mm.
Custom Builds and Ordering
Cable length, jacket colour, polarity, and connector orientation can be tailored to your build.

We support low-volume prototypes and high-volume production runs with consistent batch testing on every shipment, and can match the connector housing colour to your brand if requested.
Packaging and Shipping
Each DC plug power cable is bulk-packed in PE bags and shipped in export cartons. Standard packaging fits courier pallets; custom retail blister packs, header cards, and private-label boxes are available on request. Lead time for stocked items is typically 3–7 days; custom builds 2–4 weeks depending on quantity.
Quality and Compliance
Every assembly is continuity-tested and visually inspected before dispatch. Our manufacturing partners hold ISO 9001 quality systems; specific regulatory approvals (UL, CE, RoHS, REACH) for finished assemblies depend on the chosen jacket material and connector brand — please confirm requirements when requesting a quote.
