• Fully supports PD 3.1 EPR protocol, with maximum output power up to 240W (48V/5A), providing full-speed charging for high-performance gaming laptops, mobile workstations, and high-power devices.

• Utilizes a four-channel parallel copper core structure, with each channel supporting up to 5A current, totaling 20A current-carrying capacity, ensuring stable long-term full-load operation.

• Built-in intelligent power negotiation chip automatically recognizes device power requirements and allocates power output accordingly.

2. High-Gloss Mirror-Finish Aluminum Alloy Industrial Design

• Connectors are made from aerospace-grade aluminum alloy with precision CNC machining, featuring an eight-step mirror polishing and anodizing process that presents a premium titanium space gray metallic luster.

• The high-gloss mirror finish not only enhances visual quality but also provides fingerprint and corrosion resistance, maintaining its shine even after prolonged use.

• The structure passes 2,000 plug/unplug tests and 50N lateral pull tests, ensuring stability during high-power connections.

3. Four-Core Parallel Reinforced Transmission Architecture

• Cable core adopts an independently shielded design with four sets of power channels (45/0.08BS+250D)*4Cu and four sets of data channels (16/0.08BS+250D)*4C.

• Each power channel has a resistance ≤8mΩ, with total line voltage drop <0.8V@240W, achieving a charging efficiency of up to 98%.

• Supports USB4/Thunderbolt 4 data transfer standards, with theoretical transfer rates up to 40Gbps, meeting high-speed large file transfer needs.

4. Professional Heat Dissipation and Safety Management System
