Construction and Materials
Moulded USB-A plug and 5.5 x 2.1 mm female socket, both with strain relief. The middle section is a flexible coiled spring that extends from rest length up to several times its coil pitch.
Typical Applications
In-cab USB power for truck drivers, dash-cam installations, mobile routers, or any application where the device is moved relative to the USB host and a fixed cable would snag.
Compatibility and Fitment
USB-A host port (5 V). The 5.5 x 2.1 mm (5521) female mates with any standard 5521 male plug — not for 5.5 x 2.5 mm or 4.0 x 1.7 mm loads.
Custom Builds and Ordering

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.
