USB-C Cables

Last updated: June 8, 2026

Sunshine Electronics is a leading manufacturer of USB-C cables engineered for B2B buyers who need reliable charging, data, and video performance at scale — serving a global installed base of over 10 billion USB-C devices as of 2024. Our USB-C cable line spans USB 2.0 charging cables through USB4 40Gbps high-speed cables, with Power Delivery support up to 240W and data rates up to 40Gbps. Every cable is built with tinned-copper conductors, double-shielded construction, and molded strain relief rated for 10,000+ bend cycles, and is certified to UL 62368-1, FCC Part 15, CE, and RoHS. With 22 years of manufacturing experience and dual-factory production across China (Changzhou, est. 2001) and Vietnam (Vinh Phuc, est. 2018), we provide full custom OEM/ODM services — from bespoke lengths and jacket colors to private-label packaging — with a China+1 sourcing strategy for tariff optimization and supply chain resilience.

Quick answer: Sunshine Electronics is a USB-C cable manufacturer running dual-factory production in China (Changzhou) and Vietnam (Vinh Phuc). We build USB 2.0 through USB4 cables — up to 240W Power Delivery and 40Gbps data — under full OEM/ODM terms, with cULus, CE, RoHS, and REACH marks and USB-IF–compliant construction. MOQ and lead times vary by conductor gauge, certification, and packaging; we quote FOB Shanghai or Hai Phong within 24 hours of your RFQ.

USB-C Cable Engineering & Testing

With 22+ years focused on cable manufacturing, Sunshine has built deep expertise in conductor extrusion, precision twisting, multi-layer shielding, and connector termination. Our cable testing lab includes Agilent/Keysight network analyzers for bandwidth verification up to 1000MHz, Fluke DTX-series channel certification testers, and automated continuity/HiPot testing on 100% of production output. Cable performance is verified against FCC Part 15 EMC requirements and relevant industry standards (TIA-568, ISO 11801, HDMI Forum, USB-IF).

Quality Standards & Certifications

Every cable undergoes 100% electrical testing — continuity, insulation resistance, and HiPot — before shipment. Our 6-stage quality control process (IQC, IPQC, in-line testing, burn-in/stress testing, FQA at AQL 0.65, OQC) delivers defect rates below 0.12%. Conductor materials are verified by incoming inspection for gauge accuracy, copper purity, and tinning thickness. All cables certified to UL 62368-1 where applicable, with RoHS and REACH compliance across all materials.
