Construction and Materials
Moulded USB-A plug and moulded 5.5 x 2.1 mm barrel plug, both with strain relief boots, stranded copper cores, smooth black PVC jacket.
Typical Applications
Powers small fans, LED controllers, ESP / Arduino sensor boards, and other 5 V DC loads that use a 5.5 x 2.1 mm barrel jack — from a USB charger or power bank.
Compatibility and Fitment
USB-A host supplies up to standard 2.0 / 3.0 current. The 5521 barrel plug fits 5.5 x 2.1 mm female jacks only — not for 5.5 x 2.5 mm (larger inner pin) or 4.0 x 1.7 mm equipment.
Custom Builds and Ordering
Cable length, jacket colour, polarity, and connector orientation can be tailored to your build. Contact our sales team for OEM / ODM lead times, MOQ, and custom connector combinations on this DC plug power cable line. 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.
