The USAMS US-SJ581 (U82 Series) is a future-proof, high-performance Type-C to Type-C cable designed for the most demanding devices. It is one of the few cables on the market that supports the PD 3.1 (EPR) protocol, allowing it to handle a staggering 240W of power—enough to charge even the most powerful gaming laptops and high-end workstations.

Key Features:

• PD 3.1 Next-Gen Charging – Supports the latest Power Delivery 3.1 standard with Extended Power Range (EPR), delivering up to 48V ⎓ 5A (240W) and fully backward compatible with 140W, 100W, 65W, and lower-power devices.
• Integrated E-Marker Chip – Built-in intelligent E-Marker communicates with the charger and device to safely regulate high-wattage current, ensuring stable charging and preventing overheating.
• Premium Zinc Alloy Shell – Gold-plated, high-density zinc alloy connectors offer anti-oxidation performance and superior wear resistance, with in-mold molding to prevent cracking or loosening over time.
• Extreme Durability Design – High-density nylon braided cable is tangle-free, wear-resistant, and engineered to withstand thousands of bends without performance degradation.
• Tinned Copper Core – Multi-strand tinned copper wiring minimizes resistance and power loss, delivering consistent and efficient current across the full 2-meter length.
• Reliable Data Syncing – Supports standard data transfer speeds of up to 480 Mbps, ideal for syncing photos, music, videos, and documents while charging.
